Book: Wall Around A Star

Wall Around A Star


Something is coming.

Something very large is spanning the immense emptiness on the way to something inconceivably larger still …

And in it I sleep.

I sleep as I speed through the great nothingness, the width of a planet in every second, with nothing for thou­sands of years’ time behind me, and nothing for thousands of years before. I dream as I sleep. I dream of vast worlds and the unseen threads of purpose that join them; of ships like worlds, and of worlds erupting in ion bursts as they die. I have been sleeping for a time so long that there is no language to describe it. Then, for a moment, I wake.

Is it time?

I reach out to the distant starcloud before me. The stretch is immense, and it weakens me. I catch at a star and taste its planets. I savbr some of its living things, and bring them closer for HIM.

HE does not stir.

It is not yet time.

I waken some of my sleeping puppets and hurl them ahead to survey and to learn. And then I return to sleep, while the great cloud turns majestically before me, and we draw ever nearer. Now and then the least of my slaves and senses whisper to me. Strangers have appeared. They touch the farthest outreach of my person. They come, they scramble about; they die.

They are not important. I do not trouble to wake fully for them, because the time is not yet.

But it is coming. It is coming soon. 


Jen Babylon was physically exhausted, but he was too angry to go to sleep. He dropped his briefcase of tapes and transcripts, too precious to trust to a bellboy, in his hut and stamped back along the beach toward the only lights visi­ble, the tethered schooner that served as a bar and late- night snack shop. For a miracle it was not raining, but the mosquitoes were out. In five weeks in Western Polynesia he should have had time to get used to them. But that hadn’t happened. He hadn’t gotten used to the hostility of the Free Polynesians, either, and if the desk clerk hadn’t been one of them he was certainly a sympathizer.

He stopped, his train of thought interrupted. Somebody was walking up out of the lagoon.

For a moment he had, been startled; few of the guests swam after sundown, when some people thought the sharks came in from the open sea. But swimming, after all, was one of the things people came here for, and there was no northern-hemisphere insistence on lifeguards or regular hours here. So it was not surprising there was a swimmer. It was not even surprising that the swimmer was female, and apparently entirely nude. Here there was no northern- hemisphere hangup about skin, either. What was a little surprising was that she was walking straight up to the beach, not sidestepping the little patches of sea growth, not even staying on the paths raked free of shells and broken coral. She reached the high-water mark, and stopped, look­ing around in what appeared to be some uncertainty.

Babylon stopped a meter or two short of where she stood. >She was a striking woman. Not beautiful, perhaps.

Too slim to be classically beautiful, and her coloring was— strange. It almost did not exist. Even in the weak light from the Moon and from the rigging of the distant schooner he could see that her hair was so pale as to be almost transparent, like spun lucite, and her eyes were al­most colorless behind colorless lashes.

He realized he was staring, and stammered, “Excuse me.” There was a little pile of clothing tucked between the roots of a banyan. He said helpfully, “Is that yours?”

She looked at him in a strange way. Not as one person usually looks at another, making contact eye to eye, but as one looks at a statue, or a machine. It was not in any way hostile, but Babylon could find no other way to interpret it. He felt himself on the defensive. “Excuse me,” he said again. “I’m going to have a nightcap.” Just at the pier he turned. She was standing there, with the clothing in her hand, looking thoughtfully at one of the chambermaids going from cabin to cabin to turn down the bedspreads.

He ordered a brandy and ginger ale. His anger had be­gun to simmer down, but a certain amount of irritation re­mained to mix with the fatigue. His grant had been for eight weeks in the islands, traveling from one tiny atoll to another to find the oldest surviving Polynesians and get them to speak what they remembered of the native tongue into his bubble-recorder. Of course, there was no such thing as a pure Polynesian tongue anymore. The grand­fathers’ grandfathers of the old people he talked to had al­ready begun to incorporate words of French and English and Russian into their everyday speech; the consonants had shifted to match the white man’s way of writing them down, rather than retaining the original, not quite reproduc­ible sounds of the untouched islands. But that was his spe­cialty. Jen Babylon’s first doctorate was in evolutionary linguistics, his second in semantic analysis. He was the world’s outstanding expert in the history and development of tongues. “Babylon’s Algorithms” were taught in every university in the world, as a procedure for mapping loan words from a known contaminating tongue against current dialects and reconstructing the lost original of the dialects.

Not just in this world. Babylon’s contributions to linguistic theory were among the very few specimens of human sci­entific thought that any of the other races of the Galaxy considered worth the trouble of knowing about That knowledge gave Babylon a good deal of pleasure. It was a source of pride for him. Sources of pride were welcome. Babylon had spent his youth as a college grind, subsisting on scholarships, seldom finding time enough to go out and raise hell with his peers, seldom finding anyone who wanted to share hell-raising with him when he did. He was not the sort of man who attracted women. He was too short, a little too plump, a good deal too soft ever to look heroic or macho, and although he could speak easily in fifteen languages and get by with some difficulty in half a dozen others, he had never learned the words to talk to a girl.

So when the woman from the beach entered the bar he glanced at her only briefly, and then turned away.

She was dressed now—at least, she had wrapped a pareu around her, though she was still’barefoot and her glassy- soft hair was wet. To his surprise she came up to the bar next to him. She inspected the stool beside his, sat on it, and said, in a voice almost as colorless as her eyes, “I’m going to have a nightcap.”

Well, there were times when you didn’t really need the right words. “Would you like to join me? Yes? I’m having brandy and ginger ale.”

She looked at the drink as he held it up. “Yes,” she said. “Brandy and ginger ale.”

But even after he had bought her a drink the woman did not seem to want to talk. She was willing to listen, appar­ently, as she tasted her drink and stared about the little bar. “I’m going back to Boston in the morning,” he offered, without getting a response. She seemed interested in the rope festoons and seashells that were the principal decora­tions. There was almost no one else in the bar; February was not the tourist season on Moorea, and the hotel’s com­plex of thatched-roof cottages was almost deserted. He tried again. “I’ve been out in the smaller islands. I’m in linguistics.”

The woman did not respond, but the bartender looked up from his American newspaper crossword puzzle. “Were there a lot of those Polyndsie-libre types out there?”

“Quite a few,” Babylon admitted. “I think I would have had more cooperation from some of the old people if it hadn’t been for them. But they didn’t make any real trou­ble for me.”

“Bet they didn’t,” the bartender said. “They caught one of the ringleaders, you know. That Te’ehala Tupaia. A mad bomber! Worst of the lot. Between them and the Kooks, this place is going to hell.”

Babylon was startled. “No! I didn’t know you had Kooks out here.”

The bartender shrugged moodily. “Not right here, but over yonder”—he waved toward the distant lights of Pa­peete, climbing the mountain on the other side of the strait—”there’s plenty of them all over Tahiti. I never go there anymore. Would’ve stayed in Cleveland if I’d wanted to see a bunch of nuts dressing up like freaks and acting like the world was coming to an end. Maybe it is. When I was a boy—”

Jen Babylon didn’t want to hear about how things had been when the bartender was a boy. “Are there Kooks where you come from?” he asked the woman.

She glanced briefly at him through her pale eyes, then away. “No.”

“There are plenty in Boston,” he told her. “It’s a new religion. They said that object that was discovered a few years ago—Cuckoo, most people call it—anyway, they think that when it reaches our Galaxy we will all be de­stroyed. Or reborn, as something bigger than human. Or something …” She wasn’t paying attention. At least, she wasn’t looking at him, although there was something about her that made him sure she was hearing every word. He was receiving mixed signals from her, and it was both irri­tating and in some way provocative.

More irritating than provocative, on balance; he was still not over the anger left from his unsatisfactory conversation with the desk clerk. Were there any messages for M’sieur Jen Babylon? Perhaps yes. Perhaps no. One had so many messages—but it was obvious the hotel was nearly empty, and there were hardly any signal lights glowing over the room indicators. But couldn’t he just look? With great re­gret, m’sieur, not at this moment, since the press of duties was so formidable. And m’sieur’s bags could not be brought just now, but surely within the hour, perhaps. Babylon had stalked out, jangling the key to his cottage. He was certain that there must be messages, if only one from the univer­sity to explain why he had been called back so urgently from his field trip.

“Do you want another drink?” the bartender asked. “Looks like you’ll be here awhile.”

Babylon realized that the staccato drumming that had been nagging at his consciousness was rain, beating down on the moored old copra schooner with the sudden violence of any tropical storm.                i

“Might as well. How about you?” he added to the girl.

She stood up. “No.” She moved toward the door without looking at either of them.

“Miss, where are you going? It’s pouring out there,” the bartender cried.

She paused in the doorway. “I’m going to Boston in the morning,” she said. Babylon and the bartender glanced at each other, then turned together to stare out of the port­hole. She strode steadily down the pier, ignoring the down­pour, looking neither to left nor right until the rain swal­lowed her.

It was five drinks later before Babylon was willing to follow her. The rain had diminished, but not stopped. By the time he reached his hut he was soaked and more irrita­ble than ever. The desk clerk did not even answer his call; the vision cube glowed orange and empty, with a taped voice saying brightly in four languages that the guest’s call would be returned as soon as possible. Babylon understood them all, and none of them made him happier. He was more certain than ever that the clerk was a Free Polynesia fanatic, with the cold rage toward all Europeans that he had experienced on the outer islands. But knowing that did not suggest anything to do about it. He slept.

He did not sleep well—too many drinks, too much fa­tigue, too much irritation. At first he was dreaming of his speech laboratory in Old Cambridge, and the dean was snapping at him as he tried to puzzle out an obscure un­known language. His best Pmal translators could offer no clue; his computers rejected all programs as nulls or errata; and he was aware that more than his job, or even his life, depended on the outcome. He woke abruptly, in a sweat of fear, fumbling for his glasses.

It was still raining. He had slept less than an hour, but a cold wet wind was coming in through the slatted blinds. He closed them and climbed back into bed, reassuring himself that it was only a dream.

This time his dreams were more pleasant. A beautiful woman who seemed transparent as glass was leading him through a marvelous drusy cave. All about them were fac­eted diamonds and opals and rubies set into the rock walls. Not rock; even the walls glimmered and glowed, like a pre­cious metal. The woman did not speak, but he was content to be with her in silence. And then he looked away, and turned back to her, and she was gone. In her place was a cluster of great bright flowers that hung in air, while giant butterflies swam among them. It was hard to tell blossom from butterfly. Both seemed to be speaking to him, too low to understand, in tones like the chiming of a golden bell • . .

He woke up.

There was a chiming, and it came from his stereo cube. The bright orange number 4 danced under a legend that read messages waiting.

He sat up on the edge of the narrow bed, rubbing his eyes as he peered nearsightedly at the stereo. Jen Babylon was one of the very few human beings who wore glasses, rejecting both contacts and surgery, preferring to accept the amused stares of his colleagues and of strangers. And of course the confounded things were never there when he wanted them. He could see, behind the glow of the messages-waiting legend, what looked very much like the fluttery figure of his dream, but its outlines were fuzzed and unreal as the dream itself.

His search for his glasses was not in the least helped by the fact that his head was feeling the drinks he had had the night before, or that it was only five in the morning, more than an hour before he had planned to get up. When at last he found the glasses, next to the bed where they always were, the image snapped into clarity.

It was a butterfly! Or not quite, but something with filmy wings and more eyes than seemed necessary, dancing back and forth in the limited loop of the stored image.

It was a TWorlie!

Babylon’s jaw dropped. There were only a handful of TWorlie on Earth. One of the oldest and proudest races of the Galaxy, they spent little time on the new member of the Galactic Confederation, the Earth, or its semicivilized peoples. And this one, he saw at once, was not on Earth. The TWorlie came from a light-gravity planet, far out in the Orion arm. One of the reasons they disliked Earth was that its heavy pull crushed them to the ground; a TWorlie on Earth had to creep around the surface like a wounded moth, prisoner of a tenfold weight increase that its filmy wings could not support. But this one was flying free.

Bemused, he stared at it for several minutes before it occurred to him that the message itself might answer his questions. “Release message,” he ordered the stereo, and at once the repeating loop opened out and the butterfly crea­ture drew itself up and spoke to him, dancing and whisper­ing. It was speaking in its native language, Babylon knew, but the whispery-chirpy TWorlie speech was not one of the galactic tongues he understood at all. “Translation mode,” he commanded, and obediently the stereo interrupted the audio portion of the message to recirculate the message through its built-in Pmal circuits. Out here in the islands one could not expect really sophisticated machinery, but the artificial voice-over was clear enough:

“Communication for Dr. Babylon Jen,” it rattled. “Mode urgent. Concur requisition to study unidentified spacecraft. Urge immediate compliance.” And the image faded.

Babylon got up and made himself a cup of coffee from the autobar. It was strongly laced with chicory or some other substance, not at all what he was used to in Old Cambridge, but it contained caffeine enough to shock his nervous system awake.

He stood frowning at the lightening sky across the strait. What requisition? What was he being urged to comply with immediately? Above all, what “unidentified spacecraft”? And how much of his uncertainty was due to the inade­quacy of the stereo’s primitive translation circuits, and how much to the peremptory nature of the T’Worlie?

The stage chimed gently to remind him that there were other messages. He sighed and said, “Release next mes­sage.”

As he turned back to the stereo an ugly image was form­ing. It was not flesh and blood at all. It was a queer, box­like shape that hung in space within the three-dimensional stage, so lifelike that he could almost smell the acrid reek of the faint wisps of steam that issued from its edges. It was a robot, probably Scorpian—and again, since it hung easily in air, almost certainly not originating from Earth.

The creature spoke, and the Pmal rattled out its transla­tion:

“Jen Babylon,” it rapped, “you are not under any cir­cumstances to accept transmission to Cuckoo. The conse­quences will be extremely grave. You have been notified.”

Babylon swore softly to himself; it was a morning for confusing messages. “Release next message,” he com­manded; might as well get all the confusion at once.

This one at least was human—even a human being he knew! It was the dean of his department, Margaret Koose- man, seated at her desk and beaming pleasantly at the transmitter. “I’m terribly sorry to interrupt your trip, Jen, dear,” she said, “but this is a very great honor! Not only for you. The whole school will benefit.” Her leathery old face was flushed with pleasure. “By now,” she went on, “you will have received your travel itinerary, and I suppose this message will catch up with you somewhere before you get to Boston. Please come to see me as soon as convenient. I want to take you over to the public-relations people so we can get a little publicity out of this appointment for you. I can’t tell you how much I envy you!”

And the stage went to orange fuzz again.

Babylon did not try to interpret. He snapped, “Release last message.”

But all it was, was a telephone code and instructions to call someone named Ben Pertin at it; and, when Babylon tried the number, it did not answer.

That was a puzzle of a whole other kind. Ben Pertin! He knew the name. It was an old school chum whom he had not seen in a good many years. Why would Pertin be call­ing him here? For that matter, how had Pertin tracked him down? He had not himself known he would be staying at this hotel until the peremptory recall order and travel in­structions caught him between atolls, the day before … And something else nagged at him about Ben Pertin, al­though he could not think just what.

It was all very puzzling. Babylon, sitting on the tiny porch of his shack, with the rising sun making ripples of blood on the gentle lagoon, could understand only that he was being asked to do something, which someone else didn’t want him to do, but which the powerful dean of his department could see a solid advantage in for herself.

He shook his head and got up for more coffee from the autobar. One alien creature told him to do something. An­other ordered him not to. His dean was all smiles and sweetness without saying what she was being sweet about; and he had a call from someone he hadn’t seen in years; and why was it all happening? What had suddenly made a respected, but really rather obscure, professor of quantum- dynamic linguistics suddenly so interesting that people sought him out?

There was no answer. He lifted the cup to his lips—then caught sight of the stereo box. The time! He should have been packed and out of there! That Polynesie-libre desk clerk had failed to call him; and now he had about ten minutes to get to the island’s hoverport!

Jen Babylon’s specialty was the deep structure of lan­guage. The fact that it was technically called “quantum- dynamic linguistics” offered clues as to what it was all about, but hardly one human being in a thousand could have explained what the name meant, and fewer than one in a million had any real grasp of its principles.

Linguistics had come a long way since the early studies of Chomsky and Babbage and Korzybski and Claude Shan­non. As the pure study of the structure of language, it dated from Chomsky’s discovery that sentences which seemed identical in structure were, in fact, essentially and wholly different from each other, and that, even more puz­zling, every English-speaking person knew this without knowing that he did. The sentences were not complicated: “John is easy to please.” “John is eager to please.” Every­one understands both those sentences, and generations of grammar-school teachers have shown their ten-year-olds how to parse them, as if they were identical. Then Chom­sky came along. He pointed out that they could not be the same since if you translated them from the active to the passive voice they could not follow the same rules. “It is easy to please John” is good English. “It is eager to please John” was instantly recognized as a false sentence by everyone who spoke the language, even the ten-year-olds. From clues like this Chomsky developed his theory of deep structures and of an underlying rule of law that pertained to all languages—every language that had ever existed on Earth, and even every language that ever could exist, any­where. Sometimes his rules were called transformational grammar, and that was the beginning.

At about that same remotely historical time, Korzybski began that search for meaning he called semantics, Shan­non developed the notion of the unit-quantity of informa­tion that he called a bit, and many workers, building on the pioneering Babbage and others, developed rules of expres­sion that permitted them to draw diagrams and equations to test statements for truth or falsity. Boolean algebra and Venn diagrams played a part in what Jen Babylon did, but they, too, were only a beginning. The science was known as quantum linguistics when he came to it. The “dynamic” part was his contribution. For with Babylon’s Algorithms, it was easy to write computer programs that could pene­trate the deep structure of even a totally unfamiliar lan­guage, given almost any contextual clues at all.

Jen Babylon, however unprepossessing he might seem at first contact, had revolutionized his science, and now, still young, he was receiving the rewards and paying the penal­ties. Sometimes they were the same thing. Travel was one of the perquisites, but it also kept him from any permanent relationships. He needed the freedom to go where his work took him, sometimes at a moment’s notice: to Indonesia to work on the symbolism of predawn man’s first few scratched symbols (were they true writing? the most ex­haustive studies had yet to be sure); to Baffin Island, to tape a few dying words from the suddenly discovered last survivor of a vanished Eskimo tribe; here to Western Poly­nesia. Even to the Extra-Solar Studies Commission in Bei­rut, when a thorny problem came up in designing transla­tors for the languages of the other galactic races. So he spent a great deal of his time in aircraft. When he missed his shuttle to the supersonic field on Tahiti, he had experi­ence and resource enough to find another hovercraft from the other side of Moorda; he battled through customs, car­ried his bag in his hand, and leaped onto the hydrogen- fueled 3000-class jet just before the doors closed and the loading ramp pulled away.

He was used to having people stare at him as he made one of these last-minute rashes. This time, though, the heads were turned in a different direction, and to Baby­lon’s surprise he saw the woman from the hotel beach standing in a distant aisle, looking as remote as ever while an Air France stewardess expostulated with her. At least this time she was dressed! But she seemed to be wearing the same pareu, no more carefully tied than before. Whatever the problem was, it was submerged in the seat-belt sign’s urgency; Babylon strapped himself into his reclining couch. The big hydrogen jet streaked off the long over-the-water runway from Faaa-Faaa Airport and pointed its narrow nose toward the distant North American shore. As it climbed at its steady 3,000 kilometers an hour Babylon pressed the sleeper button, and his chair elevated and ex­tended itself to become an upper berth. He had cultivated the ability to sleep when he could; and he began to drift off easily …

And then came abruptly awake.

Ben Pertin! The man who had called him, the man he had not seen for years—suddenly Babylon remembered why that was so. They had lost touch, true, but there was a stronger reason than that.

It had been just a few years after graduation, in an acci­dent while spearfishing in Long Island Lake. Pertin was always a restless, ever-moving sort of person, always look­ing for a new experience.

He found one there, at the bottom of Long Island Lake. His oxygen regulator failed, and he drowned.


The stewardess woke him up in plenty of time for him to drink a cup of coffee, splash water on his face, and be ready to disembark, but the Kooks had other plans. They interfered. The main landing strips at Logan-over-the-Sea were blocked by a Kook demonstration. The plane had to circle nearly an hour, at a prodigious waste of hydrogen fuel, while the airport police struggled to get the religious procession off the runways. By the time the plane got to its dock, and Babylon had completed the customs formalities and reclaimed his bag, it was full morning, and he decided against going back to his apartment. It was time to find out what this was all about.

He had difficulty getting to a phone because the rem­nants of the Kook mob were still being rounded up in the main lounge. They were disagreeable-looking people. It was an article of faith with the Criers of Cuckoo to renounce everything of this world; they wore clothing till it fell off them, they ate barely enough to sustain life, they preached the imminent coming of Cuckoo the Savior and Destroyer at every hour of each day. All of this left them little time for any of the normal preoccupations of humanity—such as earning a living. Their fasting had the additional effect of making them terribly, scarecrow lean—very much like the only race of indigenous humans that had been found on the strange, extragalactic object itself.

That, and their other habits, had one more effect. They smelled bad. Babylon averted his face, and tried to avert his nose, as he called the university’s code on the stereo- phone. “This is Jen Babylon,” he told the message-taker.

“Please enter an appointment with Dean Kooseman for me in, let me see, half an hour.”

The empty golden glow inside the stage stirred silently, and then a sweet mechanical voice said, “Thank you, Dr. Babylon. Your appointment is confirmed.”

He tagged his suitcase for delivery directly to his apart­ment and hurried toward the Cambridge subtrain.

He stopped short, staring at a knot of the Kooks being herded toward the limits of the airport.

Because of Babylon’s specialty, he had some familiarity with the languages, and thus with the appearance and life­styles, of a dozen or more of the major races of the Galaxy. And because the application of his algorithms required contextual clues, he had spent a good deal of time studying the collective societies of the creatures from Bootes, and the methane worlds that swung around the core stars, and the plantlike beings who swam in the seas of a planet in the Orion gas cloud. Like everyone who lived in a major city, he sometimes caught a glimpse of, sometimes even met, some TWorlie or Arcturan as they limped around the hos­tile Earth streets.

But—here? For among the ragged human Kooks there were three who were not human at all, two doughy, soft Sheliaks and a creature who looked like a purple sea anem­one. That was hard to understand! As recently as the few weeks ago when he left for his field trip, the Kooks were scarce, unimportant, and, of course, always human. Barely human; they came from the cast-offs of society. But if they were now attracting the great old races of the Galaxy there had been some significant change . . «

Dean Margaret Kooseman, at whatever age she was past eighty, should have been retired decades ago to make room for younger people. But she was kept on, year to year, be­cause of her immense prestige in the field. It did not mat­ter to the academic decision-makers that most of that pres­tige was borrowed from the discoveries and innovations of her underlings, whose papers were always coauthored by M. Kooseman, Ph.D., D.H.L., Sc.D. She got the credit, be­cause she was the boss. “Jen, dear!” she cried, getting up to brush her leathery Hps across his cheek. “Isn’t it exciting? Did those crustaceans bother you on Moorea?”

At eighty-plus, she was still a surprising woman. “What crustaceans?”

“Why, giant crabs of some sort. It was on the news this morning. They swarmed ashore out of the sea.”

“I don’t know anything about giant crabs, Margaret.” He sat down on the edge of the very soft, very deep armchair she kept so that she could put her visitors at the disadvan­tage of being trapped in it. “I was laid over in Greater Los Angeles for almost ten hours, so it’s been some time since I left Moorea, and that must have happened after I left. Any­way, that’s not what I want to talk about.”

“Of course not, Jen dear! You’ll do the school great credit. When the call came in from Tachyon Transmission Base requesting your services I was simply thrilled.”

Tachyon transmission! But he was not surprised; the summons, and the warning, had certainly come from off Earth, and there was no other real way to travel in space. All physical objects were bound by Einstein’s immutable speed law; it was only when coded as tachyon bursts that one could travel a light-year in less than one year. “What I don’t know,” he said, “outside of why I’m supposed to do this in the first place, is where I am supposed to go.”

“Why, Cuckoo, dear. I thought I told you. Didn’t you get my message?”

“I got your message and you didn’t tell me. For God’s sake, Margaret, why am I supposed to go to Cuckoo?”

“Because you are the world’s greatest expert in quantum-dynamic linguistics, of course.”

“But why?”

“Oh, well, Jen,” she said vaguely, “they didn’t exactly state, but of course it doesn’t matter. It’s not just your own career that’s at stake, or even the school’s honor. It’s quite a feather in the cap of the human race! There’s not a lot of respect for humanity in most of the Galaxy, you know. To have those stuck-up creatures send for a human being to solve a problem that they can’t handle is—well, it makes me proud! And there’s no use asking me what the task is because I don’t know, but of course it doesn’t make any difference.” She was looking faintly annoyed. “It will only take a minute of your time,” she pointed out.

He scowled at her. “That’s not true.”

“Yes, it is, Jen dear. Oh, not for the you that goes to Cuckoo, no. That might take days, I don’t know, perhaps even weeks. But the you that’s here in this chair will be right back in it this afternoon. You just walk into a box, and then a minute later you walk out of it again, and that’s all there is to it. The scanners read out the total data on every atom of your body, and then they transmit your blue­prints over the faster-than-light tachyon beam to— wherever. Wherever in the Universe you want to go. In this case, Cuckoo. And when the blueprints get there, they’re read and used to form high-energy plasma into an instant, exact, living duplicate of yourself. He is you in a sense, Jen, that’s true. But the other you—the real you that’s sit­ting in my chair right now—that you will be sitting there again when the other one’s a zillion light-years away.”

“But—Cuckoo! Why, that’s clear out of the Galaxyt And besides, I’ve heard of foul-ups. Transmissions that got garbled. People coming out of the other end in the form of messes that you wouldn’t believe.”

“No, Jen, not anymore. The signals are self-regenerating now, and that just doesn’t happen—well, not often, any­way. Unless they’ve decided to edit the transmitted person in some way, to make it possible for him to survive in the new environment—but why are we talking about this, Jen? It’s all the other you, isn’t it?”

“I don’t want to go to Cuckoo!”

The dean leaned back and looked at him thoughtfully.

“Jen, dear,” she began, sweetly enough, “I’ve always said my department is about as loyal to the university as any faculty we have. Of course,” she added meditatively, “I certainly would not want to put any pressure on you. You know that. It’s not the way I do things. Never fear, if you chicken out there’ll be plenty of other volunteers! So, in a sense, it doesn’t matter. But on the other hand—”

Here it comes, Jen thought, as she reached across the desk to pat his hand. “On the other hand,” she said, “there’s your own future to consider. I’m not getting any younger.” She smiled the shark’s smile that had been in the dreams of generations of students and junior faculty mem­bers. You never knew when Margaret Kooseman was going to open those jaws and eat you up. “When I retire, Jen, I’ll of course nominate a successor, but the final decision is up to the faculty senate. And then this would look very good on your record. I mean, if you had any interest in becom­ing dean yourself.”

“Margaret! That’s blackmail!”

“No, Jen, just the facts of life. You’re due over at the Tachyon Transmission Base in three hours.”

“Three hours! I can’t be ready that fast.”

“There’s nothing to get ready, Jen. I’ve had two of your graduate students pack up your Pmals and your microfiche library already. It’ll be there when you are.”

“But— But—clothes! Personal possessions!”

“You won’t have any need for personal possessions on Cuckoo, Jen. They’ll give you everything you need. So that’s settled.” She beamed at him fondly. “And listen, Jen. If you and that pretty graduate student of yours are free tonight, two of the trustees are coming to my place for dinner. I’d be honored to have you come and be intro­duced, as the university’s first volunteer for Cuckoo!”

For all of his life Jen Babylon, like most of the human race since the beginning of time, had been one, single per­son, with a single past and a single future and no complica­tions about which “he” was “him.” There was something terribly troubling about facing up to the knowledge that in just a few hours he was going to be split in two. Two of him! Two Jen Babylons! One here, living the cherished fa­miliar life; the other in some unimaginably distant place, doing heaven knew what. It was not even comprehensible, in an intellectual sense. But there was something heavy and quivering at the pit of his stomach that comprehended it fully, and was in shock.

The mechanical voice of his cab sang sweetly, “You have arrived at your destination, sir. Please insert your credit tab under the flashing orange light and then exit on the curb side of the taxi.”

He was at his home. “Oh,” he said. “All right.” In spite of having slept three separate times in no more than thirty- six hours, he felt no more than half awake as he stumbled into the lift shaft and up to his small fiftieth-floor apart­ment. It wasn’t until he had tried the electrokey three times without getting the door open that he realized it was locked from inside.

Someone was in his apartment. He knocked, frowning. Perhaps it was Sheryl, the graduate student who had sup­plied as close as he came to a relationship. But it was not like her to be in his apartment when he wasn’t there, espe­cially since she probably had no idea he was nearer than Bora-Bora or New Guinea.

When the door opened it wasn’t Sheryl. “Good God!” Babylon said, startled. It was his mysterious caller of the night before, Ben Pertin.

But it was not the Ben Pertin he had known in the un­dergraduate days. This one looked far older and more worn than the dozen years between could explain. “Jen! It’s good to see you,” Pertin exclaimed, and then responded to the expression on Jen Babylon’s face. “Sorry about the way I look,” he said wryly. “Tilings are pretty rugged on Cuckoo.”

Babylon shook his hand absently and then, realizing that it was after all his own threshold that he was standing at, entered his tiny apartment. Pertin had been there for some time, it appeared, and had made free use of it. Glasses were stacked at the utilitarian kitchen area, and the neck of an empty bottle protruded from a trash basket. The sleeping couch was in its daytime mode, but the dangling edges of bedclothes showed that it had been used. “Your friend Sheryl let me in,” Pertin explained apologetically. “I meant to clean up before you got home, but—”

“It doesn’t matter,” Babylon said automatically, and then realized it was true. In comparison with Pertin’s pres­ence here—from Cuckoo!—it mattered not at all.

“I’m sorry if I’ve been rude,” he said, “but you’re quite a surprise! The thing is, I’ve just been told I’m going to Cuckoo myself.”

“You are! God, Jen, that’s marvelous! I hardly dared hope you’d do it.”

“Actually,” Babylon said, “I don’t seem to have much choice.”

Pertin’s face fell. “Well, I’m sorry about that,” he said, with embarrassment. “But we really need you! You see, we just-—”

“Wait a minute, Ben. What do you mean ‘we’?”

“I mean us, all of us on Cuckoo—all the people, and the other races, too. That’s why I came here to get you—and, of course, I’m still there, too,” he added, in a tone that seemed packed with both pain and rage.

“Because you were tachyon-transmitted here?”

Pertin nodded, and sat down in one of Jen’s chairs, reaching for a half-finished drink. “The Sheliaks’ll be fu­rious,” he said. “They forbade me to do it, but you’re needed, Jen. A few weeks ago we sent out a probe and it found something. A ship. Or perhaps a fleet of ships; or a city—it’s hard to tell where one leaves off and the other begins. It’s immense, and it’s terribly old. And we can’t get close to it.” He finished his drink moodily, started to get up to make another, and then, remembering, looked guilt- stricken. “I hope you don’t mind my helping myself, Jen? Would you like one?”

“Go ahead, fix your drink. What about this ship?”

“It transmitted a message—aural, received by the exter­nal microphones on the probe, and visual, received on a dozen instruments at once. We can’t understand it. I’m convinced that it’s the key to entering the ship, but without it—well, it repeated the message three times. And then the lander probe stopped sending.. It was destroyed.”

“You must have Pmal translators—”

“Oh, hell, Jen, of course we do. They don’t work. The language of the message is so different from anything in the Galaxy, anything else we’ve encountered even on Cuckoo, that there are no analogs to work from. So we need the best linguistics person there is—and that’s you, Jen. So I came here, and I pulled a few strings with the tachyon- transit people, and they pulled a few at the university …”

“Thanks,” Babylon said, with an edge to his voice.

Ben Pertin seemed to shrivel suddenly, as if expecting a blow. And then he laughed. “Oh, I don’t blame you, Jen. Cuckoo’s the garbage heap of the Galaxy, and all of us on it are stepchildren. They transmitted us out there, and most of us die, and no one cares about that. And the ones that are left are trying to do a job—or some of them are, any­way—and no one cares about that, either. Cuckoo is big, Jen! You’d think all the races would get together to study it! But we can’t even get supplies. And most of the time it seems that half the beings there are principally concerned with trying to keep the other half from getting the job done. It’s rotten, Jen.” He grinned without humor. “And so you say, how do I have the nerve to make you come out there? Well, I do have the nerve, Jen. You’re needed. That’s all.”

He finished his latest drink and stood up. He frowned abruptly and caught at the arm of the chair for support. “Sorry,” he said. “I’ve been celebrating being home. Now I’ll just run along—”

“You might as well stay and have dinner,” said Babylon grudgingly.

Pertin thought that was funny. “What dinner?” he gig­gled. “I’ve been staying right here waiting for you—and, of course, I had to eat. There’s not much left, I’m afraid.”

Babylon said, “You leave a lot to be desired as a guest, Ben, but—” He shrugged. Obviously his old school friend had been under more pressure than he could handle. “We can go out and eat, you know.”

“Not tonight. There are a couple of people I need to see. One’s a girl I’ve been thinking of for a long time. The oth­er’s … myself.”

“Yourself? But Ben—” Babylon clamped his lips shut on what he had been about to say; it was far better for Pertin to look for that other self and not find it than to be told, just now, why it could not be found. “I understand,” he finished. “Good luck.”

“I do want to see you, Jen,” said Pertin, already halfway out the door. “Tell you what. I’ll come back tomorrow and take you out for a drink, all right?”

“All right,” said Jen Babylon. But as the door closed he was wondering which Jen Babylon would keep the date.


What is the etiquette when you are going to go away forever, but also stay behind untouched? Who do you say good-bye to? How seriously?

Forget the etiquette, Jen Babylon told himself. Who do you want to see again, if you are never to see her again?

The only reasonable answer was Sheryl, but Sheryl did not answer either her home line or her forwarding page. Babylon kept trying until the last minute before he had to leave his apartment, and as a consequence was late for his appointment at the Base. His jitney started off toward the great plaza along the banks of the Charles briskly enough; but at each intersection it hesitated, seeming confused. Its limited vocabulary did not allow it to explain its problem to its passenger, but as they approached the Base itself Baby­lon could see the answer. Six gray hovervans with bars on the windows bobbed gently at the approach to the Base, while furious militiamen struggled to clear a way. All the other approaches were blocked off hopelessly, and this one nearly so, by the largest mob Babylon had ever seen assem­bled in one place—and every one of them a Kook.

Babylon paid off the jitney and made his way on foot, marveling at the carpet of humanity that spread across the great lawn, the walkways, and even the roadstead. How strange they looked! Some were strange because they could not help it, being aliens from planets that circled stars thousands of light-years away: Babylon spotted several creatures that were in no way human, a doughy flying thing like a saffron amoeba, a VWorlie like the one who had addressed him so strangely, a couple he did not recog­nize at all. Of the humans, all looked strange because they cared so little for the way they dressed—or cared so much about demonstrating their difference that they wore the shabbiest and filthiest of garments. Others, the women in particular, looked strange because they had made them­selves so. Odd fashions had spread from the other galactic races to Earth. Customs from all over the skies had become a part of Earth’s culture, and some of these women wore psychedelic scents, diamond-spangled body paint; and all— all—were starved lean in mimicry of that one known “hu­man” race of Cuckoo. Babylon stepped across prone bod­ies, lying on the grass and yearning toward the great white block of the Base. A militiaman hailed him: “You! Get out of there. We’ve got to get these vans through.”

“But I’ve got an appointment for transmission—”

The militiaman shook his head. “The plaza’s blocked off till we get this mess cleared up. The Kooks aren’t so bad, we can fly the vans right over them as they stay on the ground, but you’d get creamed. Unless, of course, you want to lie down, too?”

Babylon grinned and turned away. There had to be twenty thousand people on the lawn. He marveled that this mad movement had grown so huge so quickly; there had been only a few isolated individuals as recently as a month or two ago. Off toward the river bank a militia platoon had kept a lane cleared, and he managed to get through. At the entrance to the Base he was stopped again, this time by an animated debate between a couple of civilians and a militia officer. “Are they Kooks, too?” Babylon asked a militia- woman with stripes on her arm.

She pushed her helmet back and frowned thoughtfully. “Wouldn’t say so exactly,” she said. “Least, they’re not the same as the dreary bunch on the ground. What they are is lawyers.”

“Lawyers? For what?”

“Something about the convicts in the vans,” she ex­plained. “Go on inside. You’ll see the whole thing in there, then you can come back and tell me.”

In the stately, echoing foyer to the transmission facilities there were fewer people but a greater stir. Stereostage cam­eras were set up at one end of the lobby, and a very pretty woman was talking animatedly to a group of young, angry men and women. They weren’t Kooks. What Babylon could hear of their conversation made it clear that they, too, were lawyers—apparently from the ACLU—trying to prevent something about the prison vans outside. “What they want to do,” one of the lawyers was declaiming, “amounts to an unconstitutional prolongation of their sen­tences.”

The young woman frowned thoughtfully. “But I don’t see how. These are all lifers, aren’t they?”

“That’s the exact point! They’re sentenced to serve their natural lives in prison! But what the Tachyon Base people propose is to send them off to this place, Cuckoo, as re­corded patterns, capable of being animated at any time at all—even a hundred years from now. So they may well be dead, and their sentences therefore completed, and yet they will still be subject to involuntary servitude thousands of light-years away!”

Babylon started to move closer, but his way was blocked by another militiaperson, this one a young woman with the crossed batons of a first lieutenant. “Whom do you want to see?” she demanded.

Babylon identified himself. “I’m due for transmission to Cuckoo right now.”

“They’re behind schedule—of course,” she said, and pointed. “Wait over there. There’s priority stuff to go be­fore you do.” And she was gone before Babylon could question her. He reluctantly sat down on the bench indi­cated, where a small boy, perhaps ten years old, perhaps less—perhaps anything at all, Babylon conceded to him­self, because he was no judge of such things—sat kicking the toes of his shoes together. He was hunched up in the attitude of patient obedience to the whims of grown-ups, but he looked up at Jen Babylon. “Hello,” he said.

Babylon nodded, and sat down at the other end of the bench. There was increasing noise from outside the Base, the shouts of militiamen, the whine of hovervans, and a rumble from the crowd of Kooks. He wondered if the mili­tia had carried out their plan to drive the hovervans right over the worshiping Kooks. If so, it hadn’t gone well— there was a sudden crescendo of shouts, and then the drone of the fans muted to idle. Babylon wondered what the Kooks would think if he joined them. Or if they knew that he, or at least a copy of himself, would be on Cuckoo within the hour.

“My name is David Gentry,” the boy said.

Babylon nodded.

“That’s my mother over there,” the boy persisted. “Her name is Zara Gentry. She’s famous.” He kicked a foot to­ward the stereostage cameras to show the woman he meant, his hands thrust down in his pockets.

“That’s nice,” Babylon said, only half listening. At the desk before the transmission chamber itself a worried- looking man in a red suede jumpsuit was fumbling irritably through some papers. Babylon leaned toward him and caught his eye. “I’m supposed to be transmitted now,” he called.

The man scowled and read a name off one of the pa­pers. “John Babylon?”

“Actually it’s Jen. Jen Babylon.”

“Whatever it is.” The man shuffled that paper to the bottom of the stack. “You’ll have to wait.”

“But I’m scheduled for Cuckoo—”

“Of course you are! You and fifty-seven others. We’ll call you when we’re ready, don’t worry.” And he was off, moving faster than Babylon would have believed likely.

“They’re all mixed up here, Mr. Babylon,” the boy said. He was a nice-looking kid, with startling green eyes undef the long lashes of childhood. “Are you scared?”

“What?” Babylon’s full attention was caught at last. He frowned at the boy, then shrugged. “You know,” he said, “I think I am, a little. You see, I’m going to be transmitted by tachyon beam to another planet—”

“I know,” the boy said scornfully. “Who doesn’t know all that? I wouldn’t be scared.”

“You wouldn’t?”

“You bet I wouldn’t! Boy! Going off to another planet, way outside the Galaxy, meeting all those great alien races and all—boy!”

“You make it sound pretty nice,” Babylon said wryly. And, the way the boy described it, it really did. The part that was far from nice was that, for at least one of him, it would be a one-way trip.

“I hope David isn’t bothering you too much?”

Babylon looked up, startled. The voice had been attrac­tively, huskily feminine. The face matched it, and it had the same arresting green eyes and long lashes as the boy. “This is my mom,” the boy introduced them importantly. “Not only is she a newscaster, she’s been tachyon- transported herself. Twice!”

Babylon fished the name from his memory. “Zara Gen­try. Of course! I’ve seen you many times on the stereo. Your son isn’t bothering me at all, honestly.”

“I only talk to him when he isn’t doing anything else,” the boy explained to his mother. “Can I go get a drink of water?”

Zara Gentry looked around the great hall, now relatively quiet. “All right, but don’t get in anybody’s way.” She watched him trot away and then turned to Jen Babylon. “Aren’t you the one who’s going to Cuckoo to investigate something mysterious?”

“I guess so. I don’t know how mysterious it is—except that it’s mysterious to me, anyway. My specialty is linguis­tics. They seem to think I can help them.”

“Mmm.” She looked at him speculatively, and Jen Baby- Ion realized she was trying to assess whether interviewing him would be a waste of tape. Evidently she decided it would, because she relaxed and said, “Isn’t this awful? I’ve covered Base events a hundred times before, and they usually just go like clockwork.”

“Do you know what’s holding things up?”

“The Civil Liberties lawyers have asked for an injunc­tion—they want to keep the Purchased Persons from being transmitted—and they’re waiting to hear. Of course, that mob of Kooks out there means that the messenger from the judge’s office probably can’t get through anyway, so we may be here for some time.”

Babylon laughed. “Hurry up and wait. They dragged me back from Polynesia at top priority for this—and now I just sit here.”

“Polynesia?” The woman looked at him as if she were reassessing. “Were you there when those crustaceans came ashore?”

He shook his head. “After I left, I guess. I just heard some rumors, nothing more.”

“Pity,” she said, losing interest again. “It’s quite a story. They’re not the same sort of crabs that are local there. Something special. Quite large, and— Oh! Excuse me! Time to get back to work.”

And she was up and away, toward the great central doors of the foyer. Metal heeltips clicking against the ter- razzo floor, the militia squad paraded into the Base and formed a double file across the foyer. Between them, the ragged line of convicts shambled haltingly toward the transmission chamber. The noise outside showed that the Kooks were still there, but evidently the militiamen had managed to get through. And, judging from the fact that the ACLU lawyers were standing silently to watch the pro­cession, the request for an injunction had been denied. Babylon saw Zara Gentry excitedly directing her cameramen to cover the scene, and himself moved closer for a better look.

They did not seem as if they needed a squad of militia­men to keep them in order. They had the blank faces and preoccupied stare of all Purchased People, the convicts whose bodies were sold to whatever bidder chose to make use of them. They came in all shapes and sizes, as various as the gaping onlookers or any other random ordinary clutch of human beings. There was a young girl with flow­ing blond hair between two immense, squat, dark-skinned men, a stout grandmotherly woman of at least sixty follow­ing a scar-faced boy surely still in his teens. The militia squad did not seem to be earning their pay. Society did not appear to need much protection from the stumbling, slack- jawed convicts. Not a spark of volition was visible in any of them.

They came quite close to Jen Babylon as they lined up for their transmission. How many of them were there? Fifty-seven, someone had said, with fifty-seven individual life sentences at least among them, for no fewer than fifty- seven separate terrible crimes. Babylon wondered what the crimes might have been. Only doers of victim crimes or unforgivable crimes against the state—murder, rape, kid­naping, terrorism, and the like—were sentenced to be sold as some other creature’s puppets. And then only if the convicted criminal refused psychiatric help or was a multi­ple recidivist.

It struck Babylon that he was looking at people who would be his neighbors in a very short time, for they were destined for Cuckoo.

But that was wrong. Whatever made these fifty-seven creatures individual would be blanked out by the power of the creatures who purchased them. They would be no more than containers for alien personalities. Babylon wondered uneasily what their new owners might be like. They could be almost anything. With all the races of the Galaxy ex­changing representatives, there were a great many who could not survive in such appalling stews as the damp, oxygen-rich air of human birthright. The opposite was equally true, to be sure, but humans were not made wel­come on some of the more advanced planets, whereas nearly every race had sent at least a few observers to see quaint, primitive Earth. Some came in edited forms, rebuilt to adapt to terrestrial conditions. Others bought convicts like these from the penal authorities, and impressed their own wills on the human bodies.

So whatever these fifty-seven might have been in their own persons, when he met them again on Cuckoo they would be Other. They would become alien in their drives and motivations, whatever their physical forms might have preferred, and every act and thought and sensory impres­sion would be relayed to their distant owners, on whatever chlorine-aired or stormy liquid world they inhabited. There was a superstition that long-term Purchased People came to resemble their owners—whether primate or lizardlike, en­ergy beings or dissociated swarms. This was nonsense, Babylon thought. Probably it was nonsense …

But he was glad, all the same, that he was not one of the fifty-seven.

“Hey, you—hold it!” It was a militiaman’s voice, but there was more laughter in it than threat. The knot of Pur­chased People clotted to a stop, and a small figure darted through them and past the laughing militiamen. It cata­pulted into Jen Babylon and stopped.

“Excuse me, Mr. Babylon,” it said. “Mr. Babylon? Have you seen my mom?”

It was the kid, David Gentry. Babylon turned him around by the shoulders and steered him toward his mother, vivaciously speaking into her microphone while her cameramen were shooting the Purchased People, and as he watched the boy scurry toward her a hand fell on his shoulder. It was the man in the red jumpsuit.

“Mr. Barnaby?”

“That’s ‘Babylon.’”

“Yes. Come with me for briefing, and don’t get mixed up with that lot. You transmit right after them.”

“And about time,” said Jen Babylon.

The official stiffened. “Do you think I don’t know that? Shocking how these people interfere! The traffic that’s pil­ing up—the schedules that have to be rerouted—shameful! I’ve always said it’s a mistake to coddle these jailbirds,” he said, glaring at the Purchased People as he led Jen past them. “Scan ‘em and file ‘em, use ‘em when you need ‘em—what’s the use of letting them walk around when they’re not being used for anything? I tell you, Mr. Barab- bas, criminals ought to be treated like criminals and not like regular full-fare paying passengers like yourself! No wonder the country’s going to the aliens!”

It all happened so quickly there was hardly time to won­der if it would hurt. It didn’t. There wasn’t any pain at all. They inventoried his clothing and the contents of his pock­ets, gave him a claim check for the baggage that had been transmitted on ahead, and pointed to a door. He went through it, expecting a waiting room. It wasn’t a waiting room. It was a tiny chamber, close as a coffin, and the door slid terminally shut behind him. A sweet electronic voice urged him simply to stand still. He closed his eyes on the studded walls and then, even through closed lids, saw a brilliant flash of searing blue light. His skin tingled. He heard one sharp crack, like a jumping spark. A bittersweet sensation washed through his mouth, and he caught a sting­ing whiff of something acrid and strange—ammonia? Something worse?

And then it was over.

Something shifted all his senses. The sensory illusions were gone. The electronic voice announced that the trans­mission cycle was complete. A door opened, not the same one, and Jen Babylon pushed through into the foyer of the Base.

He caught the stout man’s scarlet sleeve. “Is that— I mean, is it all—”

The man looked at him pityingly. “Your first time? Yes. It’s over. Go about your business.”

Babylon let go, taking a deep breath of the air of the world he had been about to leave—the world that one of him had already and irretrievably left. It tasted very sweet.

He gazed around the foyer with pleasure. The last of the prisoners was just being conducted out through the double doors, and Zara Gentry and her son were gone. The voice of the man in the scarlet suede suddenly erupted from be­hind, lashing at an assistant: “Can’t you keep count? There were fifty-seven of them, it says so right here!”

“Fifty-eight,” the assistant said doggedly, waving at a luminous-number counter on the wall.

“Fifty-eight including him,” snarled the stout man, jerk­ing his head toward Babylon.

“No. Fifty-nine including him. See for yourself, chief.”

“Ah, what’s the use?” demanded the man. “How can they expect us to do a good job when the traffic piles up like this? That whole party for Sun One is due for trans­mission right now, and we’re not realigned! If we could just get this crowd cleared out …”

He was staring nastily at Babylon, who took the hint and strode briskly across the foyer and out the double doors.

There it was! Earth! He was still there! The grass- fringed bank of the Charles had never looked more beauti­ful, and even the last of the convicts, now being herded back into the hovervans, looked merely pathetic. Or most of them did. Strangely, one of them was looking directly at Jen Babylon. It was one of the big, dark-skinned men, eas­ily two meters tall and muscled in proportion. Babylon could not make out the expression on the man’s face. But there was an expression, and there should have been none.


A sweet electronic voice urged Jen Babylon to stand still. He closed his eyes on the studded walls and then, even through closed lids, saw a brilliant flash of searing blue light. His skin tingled. He heard one sharp crack, like a jumping spark. There was a moment of strain and vertigo, and then a door opened and he pushed through into the— Into a place where he had never been! No time had transpired for him. He felt no sense of change. The thought in his mind was, Ah, well, that’s done, now I can call Sheryl about that dinner with the dean—

And then he saw where he was; the thought perished, and something trapped in terror inside his mind screamed, Dear loving God, what have You done? This is mel A harsh flood of light stung his eyes. He tasted a dry, sour tang at the back of his throat. He was floating! There was nothing under his feet, nothing but air. He felt a terrifying sense of falling. As any .organism will when first deprived of the comforting anchor of its home gravity, his body spasmed in panic. He flailed wildly. His glasses went flying. One hand struck something light and fragile, and a sharp reek of vinegar struck his nostrils. He bounced against some sort of machine, caught an edge of it, and stared around. A creature with filmy wings and the tiny, hideous face of a bat was twittering shrilly at him. The creature was too tiny to be frightening, no larger than a crow, but it was furious. “Did I hit you? Sorry,” he said. It stared angrily at him out of an excessive number of eyes and flew out of sight.

He caught his breath. The truth was all beginning to penetrate. Good-bye Sheryl. Good-bye comfortable little apartment, good-bye hopes of becoming dean. All those things now belonged to the life of someone named Jen Babylon; but he was not that Jen Babylon. He never would be again.

He shifted position, lost his grip, and floated, tumbling, out into the room again. It was disorienting, but his mind was too full of sudden rage to care. It was a fraud! He had been cheated! It was not some disposable duplicate that was condemned to live out the sorry tatters of a useless life on Cuckoo—

It was himself!

From just outside his range of vision a voice spoke:

“Ah, welcome, dear fellow Earthman! Allow me to assist you.”

Long, dry, leathery fingers gripped his shoulder and stopped his tumble, and Babylon saw his rescuer. At first he thought it was an organ-grinder’s monkey, escaped from some antiquarian zoo: red vest, hat with a bright green feather, bright shoe-button eyes. A chimpanzee!

But the creature lacked the broad, protruding lips of the circus animal, and it spoke in easy English. “You did, I’m afraid, upset the TWorlie,” it chattered, “and we’re both a little bit in the way here. Allow me to assist you. Your first experience in free-fall, no doubt? Yes, I remember the feel­ing. But we don’t bother much with gravity here. Not here,” it chattered, courteously tugging Babylon toward a corridor lined with handholds, “and not anywhere around here. Not even on that great clumsy ball out the window— Oh, of course; there’s no window in the tachyon chamber, is there? But not to worry. You’ll see all you want of Cuckoo, I promise. And more.”

He clapped a skinny black hand to his unsimian high forehead. “My manners! I’m Napoleon Chimsky, Dr. Baby­lon. You can call me Doc Chimp. Now we’d better move along. Have you got everything?”

“I didn’t bring anything,” Babylon said bitterly. “Some stuff was sent on ahead—and, oh, yes!” He clapped his hand to the bridge of his nose. “My glasses. They came off when I came out of that machine—”

He stopped, suddenly aware that, for the first time in a score of years, he was seeing clearly without them. The chimpanzee chuckled. “You’ve notice^ eh?”

“I can see!” Babylon cried.

The chimpanzee bobbed his high-domed head. “A little service of the management,” he said largely. “As long as you were being coded for transmission it was easy enough to make some, ah, minor improvements. It’s called editing. Things like eye readjustments, minor circulatory problems, even malignancies—they can all be edited out automati­cally. I think you’ll find there’s not a plaque of cholesterol anywhere in your system, Dr. Babylon.” His stare became thoughtful. “It’s little enough to do for us, everything con­sidered,” he said obscurely, and then, “But please come along! It’s really not a good idea to stay here.”

With one hand dexterously catching at handholds, the other tugged Babylon gently down a corridor. Babylon in­voluntarily shrank back at the entrance. There was neither up nor down, and the corridor looked like an endless deep well dropping away beneath him. “Disconcerting? But you’ll get used to it!”

The TWorlie flew past them, chattering angrily. “Mim- mie’s a bit annoyed with you, I’m afraid,” Doc Chimp chuckled. “We’re all at sixes and sevens here, right now, because of the large shipment coming in and all the com­plications.”

“You mean those prisoners who were being sent?”

The chimpanzee nodded disdainfully. “The Purchased People, yes. And the legal problems. They should have been out of the tachyon-transporter long ago, but we’ve had orders to keep their codes stored for a while … And, of course, there’s worse than that.” He sighed, then bright­ened. “Well, just go through that door, Dr. Babylon. There’s somebody waiting for you. I’ll go back and soothe Mimmie a bit.” And he turned and was gone, launching himself back down the corridor with an amazing thrust of his skinny arms.

Babylon pulled himself carefully through the doorway, and looked around.

“Jen! Jen Babylon! Is it really you?” And Ben Pertin came off the wall toward him, arm outstretched.

Babylon hardly heard what Pertin was saying to him, hardly knew what he was responding. This person was not the Ben Pertin he had gone to school with, wasn’t even the copy who had visited him in his apartment only days ear­lier. The pleasant face was lined and bloated; the grip was flabby, the breath a clear sign of heavy and recent drink­ing. Pertin was not only unkempt, he was hardly even clean. His hair had not been cut in many months, and had not even been washed in a good long time. It swung behind him in two snarled tails as he moved. When the copy ar­rived on Earth, it had no doubt taken time to wash and dress and get a haircut before Babylon saw it; but this was the real Ben Pertin.

But the flabby face was split in a grin of incredulous joy. “You made it! I didn’t really hope you’d be in time. Did anyone see you?”

“In time for what?” Babylon demanded.

“Going down to the surface! It’s all fixed. There’s a ro­bot ship going to pick up mass for the tachyon plasma tanks, and we’ll be on it—but what about it? Were you seen?”

“A TWorlie, I guess,” Babylon said.

“Old Mimmie! That’s all right. He’s on our side … or I think he is,” Pertin mused. “It’s the Sheliaks you have to worry about, and Valeria, and the damn Sirians—and worst of all the Scorpians. Well! I’ll be ready in an hour, and the ship boosts ten minutes after that. So all we have to do is hide you until then.”

“What am I hiding from?” Babylon demanded. “Look, Pertin—what have you got me into?”

The smile faded, and the worn, bloated face sagged into lines of misery. “I guess I played a pretty shabby trick on you, Jen,” Pertin admitted. “But it’s important. Look, let me show you.” He dived back to the console where he had been loosely lashed to the wall, and struck a series of but­tons. The blank wall—or floor, or ceiling—toward Baby­lon’s left hand dissolved in a silvery mist, shrinking ab­ruptly into the sharp image of a steel-colored ball hanging in emptiness. “That’s it, Jen,” said Pertin. “That’s Cuckoo. Wait while I wipe off the cloud cover—there.” The silvery shine disappeared from the globe as Pertin made adjust­ments. “That’s it, Jen. The whole big damn balloon. Bigger than a billion Earths. Oceans. Continents. Jen, there are rivers that are a thousand kilometers wide!”

“I don’t see any rivers,” Babylon objected.

“Because they’re too small to show at this magnification. Look closely. Do you see those little dots, here and there— that one in the lower-right-hand quadrant? Those are the parts we’ve explored. The biggest of them is about the size of Australia—and all together, we’ve mapped less than a millionth of the surface. It’s as if we’d explored the Boston Common, and that was all we knew of Earth.”

“And you’ve been doing this how long?”

Pertin shrugged morosely. “Ten years and a bit,” lie said. He shook his head angrily. “Not much progress, right? But it’s not our fault! If we had the support— If we could get our requisitions filled for high-velocity scan­ners— If we could launch ten thousand satellites, with all the instrumentation we need— If anybody just cared! But we get nothing. Not even from Earth. Not even replace­ments. We’re all worn out here, Jen. The ones of us who still care are tired. We’ve all died a dozen times—and there’re plenty of beings here who don’t believe we ought to do even as much as we’re doing!”

“Hey, slow down!” Babylon said, rubbing his head. “You’re giving me more than I can handle. What do you mean about dying a dozen times?”

“Oh, you know. Transmitter copies.” Pertin was staring angrily at the great sphere. “There’s dead Ben Pertins there”—he flashed a red arrow at one of the dots—”and there, and there. And a couple that aren’t dead, quite, but might as well be for all the purpose their lives have—if we don’t solve this thing.” He made some adjustments and all the red arrows winked out but one. “Anyway,” he said, continuing to stare at the wall, “Doc Chimp’s going to come back for you in a minute, so we can hide you until the ship’s ready. I’ll explain all the rest of it as we go.”

“No, wait,” Babylon objected. “Where are we going— and why?”

“To check out that abandoned spaceship, naturally,” Pertin said impatiently. “Why do you think I got you here—so you could make a chess partner? You’re here be­cause I think you’re the only one who can help out.” He glanced sharply at the door, as there was a distant sound of chatter. “That’s Doc now,” he said.

“You didn’t tell me where!”

“Oh, that part’s easy enough,” said Ben Pertin, pointing to the globe on the wall. “That red arrow there, where one of the dead Ben Pertins is. That’s where we’re going.”

The place where Jen Babylon found himself was an enormous hollow polyhedron, orbiting around the great bubble that was called Cuckoo. Doc Chimp whispered to him as they skulked through the corridors, stopping in sud­den fright at every noise, and Babylon gleaned that each face of the figure was designed for beings of a different race. “There’s hundreds of them here, Dr. Babylon,” he hissed, towing Babylon with one long, skinny arm as he guided them through the passages with the other. “And most of ‘em crazy! But I guess Ben Line’s told you all about that.”

“Ben who?”

“Sssh! Not so loud. Oh, that’s your old friend Ben Per­tin. This Ben Pertin, that is. He gives himself a different middle name each time he replicates—me, I’m just old Doc Chimp, no matter how many of me there are. And there’re plenty now, believe me. Here we are!”

The enormous strength in those skinny limbs stopped them without a jar, and he hurled Babylon into a small chamber. “Got here without being spotted!” the chimpan­zee crowed as he followed. “Hope this place is all right,” he added anxiously. “It’s only a little hole in the wall. Used to belong to the TWorlies, they used it mostly for nesting, I think. Smells like it, too. But it’s not so bad, and anyway it’ll only be for a little while. Let me close the door,” he added nervously, pushing himself back to the entrance. “There. Now, let’s see if you’ve got the names straight. That’s Ben Lincoln Pertin you just saw. There’s another one around somewhere, Ben Yale, but I don’t get along with him so well. Neither does Ben Line.”

“It must be pretty confusing.”

“Oh,” the chimp said, considering, “not really. You can always tell Ben Line by—” The bright monkey eyes nar­rowed evasively.

“By what?”

“Oh, well, Dr. Babylon, I guess it’s no secret. He drinks.”

Babylon burst out in laughter. “No, that’s no secret.”

Doc Chimp looked aggrieved. “He’s my friend, Dr. Babylon. He’s got a lot on his mind, and I’m really glad you’re here, for his sake.”

“Well,” said Babylon, considering, “I’m glad to be here—I think.”

“That,” giggled the chimpanzee, “I doubt. I’d be a liar if I said that myself. I’ve been here eleven years, two months, and a week, and that’s a bunch of days and nights, Dr. Babylon, especially as I’ve never been able to get them to tachtran a pretty little girl chimp out here for company.”

Babylon said, “I didn’t think—I mean, it never occurred to me—”

“You didn’t think I was interested in that? Or capable of it, maybe? Really, Dr. Babylon! I guess you’ve never been at Yerkes or the Max-Planck Institute. There’s whole colo­nies of us back on Earth. They made us, you know. Loos­ened up the skull so the brain could grow, changed around our face structure and throat musculature so we could make words—I make them pretty well, don’t I? They used to think we’d come in handy for getting into small places where human beings couldn’t go. And we did. We came in even handier in free-fall, though. So,” he said wistfully, “where I wound up was Sun One. Or one of me did. Heaven knows how many of me there are, scattered around the Galaxy—and not a girl chimp among the lot of us. Now,” he said, stealing a glance at the tiny watch face almost hidden in the fur of his wrist, “I’d best go out and scout the territory. You just make yourself comfortable, Dr. Babylon. I won’t be long—and then we’re off!”

The lander was shaped something like an earthly gar­bage truck, square and equipped with hatches and endless- belt buckets to load up with whatever was at hand. It didn’t matter what. All the tachyon receiver’s plasma tanks needed was nuclear particles to engineer and shape into whatever elements were needed to reform the objects trans­mitted. The best substance was the densest, which was why the lander descended clear to the surface for solid matter instead of scooping up gases anywhere in Cuckoo’s atmo­sphere.

But the lander was a great deal bigger than any earthly garbage truck. Jen Babylon saw it through a port as they crept furtively through the empty corridors, and he decided it had to be a hundred meters in length, more than half of that in its other dimensions. They did not enter the main cargo section; there was a small built-in control section at one end, like the cab on a truck, and that was their destina­tion.

Ben Pertin was waiting for them as they arrived, and sprang forward to grasp Babylon’s hand. “You know,” he confessed, “I was beginning to think that I’d dreamed you being here—wishful thinking, you know! I’ve had so much of it these years—but it’s true, you’re here. And just in time!”

“In time for what?”

Pertin looked surprised. He pulled at one of his greasy pigtails in exasperation. “Why, to go and get some lan­guage samples, of course, and bring them back for proces­sing.”

“Processing how? With what? In Boston I had a ten- million-dollar lab—what do I do here?”

Pertin said irritably, “Oh, hell, Jen, we have equipment! Pmals and integrators—we’ve got the farlink computer that taps into almost anything in the Galaxy, although I admit it’s hard to get time on it. Anyway, you can always tachtran data back to yourself in Boston, you know!”


“Now, that’s enough ‘but,’ Jen!” Pertin snarled. “We don’t have time to argue. This thing’s going to take off in about five minutes. It’s under robot control, but Doc’s tin­kered with the programing. It will bring us right down to where the other party was lost—”

“Hey,” said Babylon. ” ‘Lost’? What do you mean, lost?”

“Oh, that’s all right,” Pertin said reassuringly. “We didn’t know what we were up against- that time. Now we’re warned. We’ll be okay, Jen.”

“You’re sure of that?” Babylon demanded.

Pertin hesitated, then grinned weakly. “How can you be really sure of anything?” he asked. “We’ve got a real good chance, though, and of course if worse comes to worst we all just hop in the tachyon transmitter and we’re right back here in the orbiter. Now, look, there isn’t much time. This is a robot lander, and it uses more G-forces than most of them, so you’ll have to strap yourself in. Doc? Help him out, will you?” He was fastening straps around himself as he spoke. “Next time you go down,” he said, crisscrossing webbing across his chest, “you’ll go de luxe. We’ve got land­ers that’ll let you down easy as a nesting dove—have to, you know, so we can fly the autochthones around. They’re built so flimsily that a good sneeze will wreck them. Not much gravity on the surface of Cuckoo, you know.”

He rambled on, while the chimpanzee secured Babylon’s harness and sprang into a niche of his own. Pertin didn’t bother to fasten himself; evidently he had enough confi­dence in those simian arms to dispense with assistance. And then they waited.

Pertin said, with a note of alarm, “Hey, we should have left before this. Doc? Did you screw the program up?”

“Not a chance, Ben Line! You know me better than that!” the ape protested.

“Then what the devil’s holding us up? I’d better take a look myself.” And, aggrieved, Pertin began to unsnap his harness.

Before he got out, Doc Chimp flung himself across the room to the door. “Wait,” he snapped, his monkey face contorted in worry. “Somebody’s coming!”

Somebody was. Now even Jen Babylon could hear the sound from outside, faint, staccato hissing like malfunc­tioning air brakes.

“It’s a damn Scorpian,” Pertin whispered, his face woebegone. “We’ve had it!”

A discolored metal cube sailed in through the door and halted itself in midair with a rush of steam. Metallic optics tilted themselves toward Jen Babylon, and a drumroll of sound struck his ears. Babylon recognized it as language, but it was not one of the galactic tongues he knew. Doc Chimp came to the rescue. “Here, take my Pmal,” he said. “Didn’t think you’d need one for this, but—” He shrugged.

The robot rattled peremptorily again, and the Pmal translator echoed in Babylon’s ear: “Jen Babylon. You were notified. You were not to come to Cuckoo. The con­sequences are grave.”

The words had an eerie familiarity for Babylon: of course, it was the same message he had received on Earth. Perhaps even the same robot. “What are you going to do?” he asked apprehensively.

“I am going to take action,” the robot thundered. “Since you would not remain on your foul damp planet, events must take their course. I propose to join you in this expedi­tion to discover for myself the nature of this wrecked spaceship. Then we will see.”

“We’ll see that you’re going to blow Cuckoo up!” Pertin flared defiantly.

“That is one of the available options,” the robot acknowl­edged. “It is strange and worrisome. It presents a threat to our orderly existence, and that cannot be permitted. But that decision has not yet been reached.”

“I suppose you’re going to try to prevent us from going there now,” Pertin said. “Well, you won’t get away with it!”

“I have no such intention,” the robot declared. “I have merely revised the programing to allow a short delay. I sug­gest you frail organics restrain yourselves; this lander will boost within fifty-five seconds 1”


As the robot lander made its occasional course correc­tions, it spun lazily sometimes this way, sometimes that. The port by Jen Babylon’s head sometimes showed the great sweep of black, oppressive nothingness that was the external sky, broken only by the distant spiral glitter of the Galaxy that contained his home. Then there was a shudder and a slow swing, and he was looking directly down on the vast bulk of Cuckoo. It did not grow as they approached. It had seemed endless even in the first minutes; but as they descended the scale enlarged. Mottled blurs resolved them­selves into mountain ranges and seas. Pale-hued splotches became clouds—cloud banks hundreds of thousands of kilo­meters across, many of them, with tints in every fre­quency of the spectrum of visible light. From where he clung behind Babylon’s neck, Doc Chimp chattered: “Im­pressive, isn’t it? A world with air and seas and land— twenty thousand times the diameter of Earth! Half a billion times the area!”

“Give it a rest, Doc,” Ben Pertin begged, staring at the instrument panel. “We’re about to enter the atmosphere— anyway, Jen’s head is bulged out with facts and figures by now. We don’t want it blowing up.”

“Thanks,” Babylon muttered; because the joke was al­most true. For many hours—he had lost count of how many—Pertin and the chimp had been talking endlessly, often both at once. In one ear Doc Chimp whispering fear­fully of strange cabals among the alien creatures on the orbiter; in the other Ben Line Pertin, alternately sobbing about his loneliness and his lost love, and boasting of how much they would accomplish now that Jen Babylon was here. Both kept a wary eye on the Scorpian, but if the robot paid any attention it was hard to detect. It hovered in the middle of the control cabin when the thrusters were off, occasionally darting to the instrument panel or to the ports with jets of hot-oil-smelling steam.

It was all too much to take in, but the central facts were certain. Fact one: Something strange was going on in the orbiter. Fact two: Something stranger still waited for them on the ground, a wrecked spaceship of unimaginable age, still capable of defending itself against intruders. And fact three: This was the end of the road for Jen Babylon. What­ever else happened, Jen Babylon—or some Jen Babylon— would live out his life on and around that peculiar body called Cuckoo; and from that verdict there was no appeal.

“Let’s hear what’s happening,” Pertin muttered, and moved a switch. At once the sweet electronic voice of the pilot program spoke to them from the instrument panel:

“Approaching entry point. Prepare for deceleration, in­creasing to twenty-eight meters per second squared, plus or minus three. Warning! Ten seconds. Five. Two. One—”

The safety rack squirmed behind Babylon’s body, drag­ging him with it. Outside, the black sky turned gray, then blazed into a sudden flare of orange as the thrusters hurled forth their vapor. He felt crushing pressure for a mo­ment—three full gravities!—then slightly less.

“Sorry about that,” Doc Chimp giggled in his ear. “Ben Line warned you this lander was a rough one.”

Babylon didn’t answer. He was staring at the spectacle outside the port. There they were, the layered clouds of Cuckoo: steel dust in the highest reaches, from crystals of frozen oxygen; lower down, luminous seas of rose, gold, green.

These were not the ragged, diffuse clouds of Earth. Their edges were sharp as knives. They were swarms of tiny airborne creatures, collective beings like the aliens from a world in the constellation Bootes, called Boaty-Bits. Each was a separate entity, but together they made a superindivid- ual, a flock or school or herd that moved together through the air. Lower still were real clouds … and below that, sinister and dark, the rough surface of Cuckoo itself.

“Prepare for landing,” trilled the sweet voice of the pilot program.

Another sudden surge of thrust; a twisting moment of vertigo; and they were stopped. Actually, the landing was surprisingly gentle. The surface gravity of Cuckoo was so insignificant that landing was only a matter of slowing the speed at the proper time. There was no clutch of gravity to cause a real crash, only the possibility of flying into the unyielding surface.

As Babylon struggled with the straps of his restraining cocoon there was a sudden stillness. Only a moment; felt more in the brain than perceived in any sensory organ. And then an immense sharp crash, like a pistol shot beside the ear. Babylon shouted in surprise and sudden shock. To his wonderment his fellow travelers seemed to take it as a matter of course. Even Ben Line Pertin only nodded, and offered a weak laugh.

“Worse than ever,” he crowed. “Why, they missed us by several minutes!”

“What in God’s name was it?” Babylon demanded.

Pertin sobered. “I told you the ship tried to repel invad­ers,” he said, busying himself with his own harness. “But it’s very old, Jen, and its reflexes are slow. And getting slower. Why, the first time I landed here it only missed us by a fraction of a second! Of course,” he added soberly, “its aim’s bound to get better as we get closer in.”

“Pertin,” blazed Jen Babylon, “I’ve had a bellyful of you! This is the last time I let you get me into something I can’t get out of!”

Pertin shrugged morosely. “Better get your gear on,” he suggested, strapping a slim cylinder to his own shoulders. “You want me to apologize? The hell I will. I didn’t ask for this job, either—and you might as well know there’s a good chance that this will be the last time for anything at all, for either of us!”

There was not much gear to put on, but none of it was familiar to Babylon. The Pmal translator was the easiest part, and the least strange: it was a simple language pro­cessor, but good enough for most galactic tongues, and Babylon had worked with far more complex versions of it back in the linguistics labs. A thruster was strapped be­tween his shoulders—”Walking’s much too slow here,” Doc Chimp chattered as he helped Babylon on with it. “Believe me, you’ve got to move briskly if you want to make it past the defenses!” And there were a dozen tools and imple­ments and weapons, none of which Babylon had ever seen before: getting into the ship was evidently not going to be easy!

The lander lay in a small declivity, with only the mottled sky of Cuckoo overhead. There was not much light; only what the distant clouds gave, no more than starlight on Earth. Babylon had hoped that on Cuckoo he would weigh some normal amount again, but the soap-bubble object was so tenuous that he seemed to weigh no more than a kilo­gram. Underfoot was a waste of sand, velvet-black, track­less, untroubled by any wind. But it was not featureless. Blue sparks of light flashed from random points within it, like the glow of a tropic surf with its luminescent organ­isms. Babylon could see the outline of his feet against the diamond sparkles of the sand more clearly than he could see the rest of him, or the others.

“Better get started,” said Pertin, his voice queerly strained as he peered over the gende rise toward their ob­jective. “Go easy with your thruster, Jen. Take time to practice; stay behind the rest of us, you can catch up later.”

Doc Chimp showed him the little lever that turned on the gentle steam jet, all the energy needed to move about in the insignificant gravity of Cuckoo. But even that was a lot! At first thrust he soared into the ebony sky, suddenly meters up in the air.

Doc Chimp, giggling, jetted after and caught him. “That way, Dr. Babylon,” he said, pointing. “No sense trying to get back to the orbiter this way—you’d never make it.” Then he sobered as they leveled off. “Question is,” he mut­tered, “will we make it at all?”

They were in the heart of an immense dark plain, and throughout it were scattered vast dark shapes. They looked like buildings, though Babylon knew that they were not But they were not natural, surely? He could not see the tops, could not even guess how high they stood. But far up he could see a section of a distant, pale cloud, cut off where a corner of one of the structures intersected it. It was at least two hundred meters over his head. “Doc, what are these things?” he demanded, staring about. “It looks like a city I”

“Heaven knows, Dr. Babylon. The T’Worlie say they’re natural—maybe living organisms. But, oh, don’t they look like a good old Earthly city skyline? Not as nice, though.” The chimpanzee was staring about worriedly. “We’d best move along—look, Ben Line and the Scorpian are halfway there.”

“Where’s ‘there’?” Babylon demanded.

“Right where those structures are thickest,” sighed the chimp. “You’ll see. Oh, never fear. You’ll see.” He twisted his spidery body in midair, activated his thruster, and soared away, Babylon following clumsily. The gentle Cuckoo gravity was forgiving and in a few moments he was able to control the direction of thrust well enough to keep a course. Below and behind him the lander had started its automatic scoops, shoveling the diamond-sparkly dust into hoppers for transport back to the orbiter, to be turned into plasma mass for the tachyon receiver. Directly under him was a cluster of jet-black prisms, then a tetrahedron of dull copper, then to one side half a dozen tall tapering cones that glowed pale gold. There were cubes like blocks of blue ice, glassy cylinders, spidery shapes that could not have ex­isted on a denser world—they stretched for endless kilome­ters across the sparkling sand, and ahead of them, past the forms of Ben Line Pertin and the robot, they seemed to cluster around a darker and less regular shape.

“That’s it,” Doc Chimp called over his shoulder, pointing as he flew through the sultry air. Real fear was in his voice as he added, “We’d better get there fast—looks like they’re waking up again.”

Babylon realized that something had changed. The struc­tures which had been only hazy outlines in the gloom were sharper and clearer now. His eyes had not become dark- adapted; the shapes really were brighter, with a glow from inside. As the chimp and Babylon caught up with the oth­ers, the Scorpian robot rattled peremptorily, and Babylon’s Pmal translated: “Caution! I sense a powerful electrostatic potential building up!”

“Get down!” Pertin yelled, gesturing toward the ragged shape at the center of the structures. The robot spurted steam and arrowed toward the ground, Doc Chimp and Pertin following quickly. Swearing, Babylon struggled to direct his thruster and join them. He made it—barely. As he touched ground and was caught by the skinny arms of the chimpanzee the brightest flash he had ever seen crack­led through the air above them, followed by the grand­father of all thunderclaps.

In the blinding blackness that followed, Babylon lay sprawled on the cold, dry sand, his ears ringing. He felt a tingle over his head and arms, and the air had a biting tang of ozone.

“Close,” Ben Line grunted, pushing himself erect. “Thank God they’re slow. It’ll be four or five minutes be­fore the next one.” He peered at the great irregular black shape before them, then gestured off to the side. “See that gouge?”

The diamond sand was plowed into a furrow so huge that Babylon had not seen it at first. It stretched as far as the eye could see, and in it structures like the ones all around them had grown. “That’s what this ship dug out when it crashed,” Pertin said, “and that’s the way we came last time. There’s not as much shelter there; maybe that’s why Doc and I got aced.” He said it so easily! Babylon thought. But he was talking about the death of his own self—or one of his selves—a self as real and aware as the one that was speaking. “There wasn’t any entrance on that side,” he continued, “and that’s probably why we got it. But tachyar surveillance shows one over here somewhere.” He was peering around the bleak, shattered face of the huge object before them. “Wish I could see it,” he grumbled.

The Scorpion robot, hovering just above them on the lazy wisps of its steam jets, rattled out: “Possible entrance structure detected. Ferronickel alloy. Surface oxidized as if from great heat and long exposure. Structure intact” A lance of red laser light sprang from one of the faces of the cube to indicate the spot.

Cautiously Babylon activated his jet, rising a bit to get a better look. “I think we can get in there,” he decided. “We’ll probably have to cut—”

“Get back down here, man!” cried Doc Chimp, clawing at his ankle; and the Scorpian reinforced him:

“Electrostatic potential building again,” it rapped out “Nearing maximum—”

Flash and thundercrack struck at the same instant, well over their heads, and at once Ben Line Pertin leaped up. “Now!” he cried. “Let’s see if we can get inside before the next one!” And he was already arrowing toward the spot the Scorpian had pointed out with the robot close behind. Doc Chimp grasped Babylon by the nape of the neck, activated his own thruster, and dragged him through the air.

“Sorry to be rude,” he panted. “But I don’t want to be airborne when that goes off again—”

“But there was plenty of time between shots before,” Babylon choked out

“Oh, Dr. Babylon, never think that,” cried the ape. “They speed up, you see. That’s how we got killed before. Now!” And he dragged Babylon down to the shelter of the - huge, ancient artifact.

A third bolt raged through the air they had just left. Babylon felt an electric sting in his teeth; it was that close.

Amazingly, Ben Line Pertin was jubilant. “Made it this far,” he cried, “and I never thought we would! Now all we have to do is get inside!”

Something, very long ago, had plunged through the shal­low gravity well of Cuckoo to wind up in this strange, black place. According to the tachyar observations, it was irregularly shaped metal with a gross mass in the tens of millions of tons—very similar to the orbiting objects they had detected high above the body, but had never been able to reach to study. Pertin’s conjecture was that one of the orbiters, ages ago, had crashed there. The reason was any­one’s guess; but the fact was their hope. Every other instal­lation on Cuckoo or around it had defenses of such might that it was impossible to get close. But this one was a wreck. Its defenses still existed, all these unimaginable ages after its crash, but they had been weakened, had become less sure and deadly.

“Deadly” was an appropriate word, Babylon thought, peering up at the irregular wall of metal that was the shell ‘ of the spacecraft. Black, rugged, shrouded in mystery, it seemed to emanate an aura of menace and immense age. Doc Chimp, peering up along with Babylon, whimpered faintly and shook his furry head. “Oh, Dr. Babylon,” he mourned, “what are us civilized primates doing here? That thing doesn’t want us!”

“Grab your tools and shut up,” Ben Pertin ordered. “We’re safe here for a little while—I think. But I don’t want to be hanging around out here if this thing gets the range and decides to blow us into atoms!”

“What can I do?” Babylon asked, as Pertin and the chimpanzee began pulling tools out of their backpacks.

“Stay out of the way,” Ben Line panted. “When we get inside youll have plenty to do, but this is specialist work. I got a Watcher to show me how the seals on their fortresses work—I think this is the same plan.”

“Keep an eye on that robot for us, won’t you?” asked Doc Chimp, extending a metal construction like a pair of dividers.

Babylon nodded, and turned away. The Scorpian, ignor­ing what the humans were doing, was thrusting away along the bottom of the derelict. So close, Babylon was able to get an idea of the object’s real size. It bulged out over their heads, roughly a globe a thousand meters through, but mis­shapen by design and by chance. Great wedges and cre­vasses had been torn out of it as it plunged through the air and along the ground; others seemed to have been designed

into it by its builders—whoever they might have been. Or whatever. It had piled up a scarp of debris and soil at one end as it struck, so that one side was buried under dozens of meters, while the other, the one they were on, lay nearly bare. Twisted and fused stumps of mysterious instruments jutted from it.

“Babylon!” Ben Pertin panted. “Now give us a hand!”

He and Doc Chimp had deployed the most complex of their tools, an affair of suction cups mounted on long pipe- stems. One set was affixed to a dimly outlined circular area that they had decided was an entrance port, the other to the scarred old hull itself. There was a crank that was meant to turn the inner circle; but in the fragile gravity of Cuckoo there was nothing for either man or chimp to brace himself against. Babylon grabbed the handle, overlapping the grips of the other two; but all three combined had not enough weight to move it.

As they struggled a drumroll from behind told them that the Scorpian had returned. “Desist!” their Pmal translators barked. “I will move that!” Panting, they backed away as the robot moved in. Metal grapples on its fore end locked around the handle of the crank. It positioned itself care­fully, and then erupted a shrieking blast of steam. The crank quivered and began to turn, and slowly the inset disk shuddered free. “Get back,” the chimpanzee chattered, as the Scorpian began to revolve with the crank. It looked like a hissing, white-plumed pinwheel as it spun faster and faster around the narrow circumference of the crank arm; and then it stopped, and the disk slid free.

An explosion of light came from inside. “Good heavens,” Doc Chimp cried. “It’s still got power, after all this awful time!” And so it did, not only for its weaponry but for a host of automatic machines, all activated by the opening of the port. A vast hooting clamor reverberated through the chamber. As the sound died, Babylon heard a beeping trouble signal from his Pmal.

“It’s language,” he cried. “The ship’s talking to us!” He checked the machine translator and found what he had ex­pected: its input circuits had diagnosed the presence of lan­guage, but it lacked any sort of translation match to deal with it.

“I think I know how to translate it,” Doc Chimp mut­tered hoarsely. “It’s telling us to get out!”

The Scorpian rattled: “Dr. Babylon! Are you recording all this?”

Before Babylon could speak, Doc Chimp interposed: “I’m doing it for him. Don’t worry, sound, vision, even smells and vibrations—it’s all in here!” He patted the bubble-recorder strapped under his arm.

“Then let us proceed,” the robot declaimed. “This cavity is an airlock. The ship itself lies beyond that second valve.”

Again the three terrestrials struggled to attach the gears and suction cups, and again the robot disdainfully ordered them away. The loud hooting continued, and the flood of light waned and waxed in varying hues and intensity. Babylon, leaping back to give the robot access to the crank, recognized the barest outlines of pattern in the sounds and lights, confirming the Pmal’s diagnosis. But none of it re­sembled any language family in his experience, and he took time to check Doc Chimp’s recorder to make sure it was all being preserved.

“What’s the matter, Scorpian? Getting tired?” Doc Chimp called. The shriek of steam was perceptibly weaker, and the flashing pinwheel slower as the robot toiled at the crank.

“Acknowledge datum,” the robot rapped. “Reaction mass significantly depleted. Project inability to repeat pro­cess more than one more time.”

“We won’t need more than this one,” Ben Line Pertin cried as the disk fell away. “We’re inside!”

And they pushed through the circular hole into silent gloom.

Whatever energies the ship had stored seemed all con­centrated in the external defenses and the lock itself. The interior was dark and still. Ben Pertin produced a search lamp, and the Scorpian suddenly did something that caused the end of one of its tentacles to flare into light. In the uncertain illumination they stared around.

If this were really a ship, Babylon thought, its crew must have been beings far larger than men. The passageways were tall and wide, and every outrageously unfamiliar structure was immense. They slid across wide planes of massive metal lace—perhaps decks? perhaps perforated for lightness? or for ventilation? The decks were at a crazy angle, and only the easy motion possible on Cuckoo’s sur­face allowed the party to move across them. They scuttled around immense rectangular structures, some pale green, others eye-straining deep metallic blue, and stared with awe at a thick column of blackness. Too light-absorbent to be anything material, it rose through one opening in the deck and vanished through another opening above.

Ben Pertin halted, flashing his light about in silence for a moment. “My God,” he said at last.

The Scorpian robot, sailing across the empty space, brought up sharply near his head. “Reference not under­stood,” it rapped severely. “Request clarification.”

Pertin shook his head wearily. “I can’t explain it to you. It’s just that—ah, Jen, what did I bring you out here for? I thought all we had to do was get inside and then it would all be clear. And now that we’re here, in this ship that’s heaven knows how many million years old—I don’t know what to do next!”

A furious drumroll came from the robot. “Clarification understood. Problem not significant. I will lead the expedi­tion from this point.”

“You!” Pertin said contemptuously. “How would you know? You weren’t even supposed to come along!”

Another drumroll from the robot, and the Pmal transla­tor rattled into Jen Babylon’s ear: “Objection irrelevant. Follow!” And the silvery cube steamed away. The white- hot spark of light at the end of its tentacle shrank with distance, outlining vast regular shapes that glinted with metal or soaked up the light like carbon black.

“Ben Line,” the chimpanzee quavered, “I don’t like this place, and most of all I don’t like following that tin can! If we primates don’t know what to do, how would he?”

Pertin scowled and rubbed his chin. “For that matter, how did he know we were coming here?” he asked. “There’re things going on I don’t understand! But what choice do we have? Have either of you got a better idea?” He paused for a second, then nodded. “I thought not, so let’s tag along. At least he’s moving slower now—too much reaction mass gone, I guess!”

Babylon tagged after the other two, his thoughts as bleak as the choking darkness they moved through. Doc Chimp, taking Babylon’s skill as now established, had left him to struggle with the delicate balance and aim of his thruster by himself; and in the black, with no reference points to guide him, his skills were barely up to it The distant spark of the robot was almost out of sight; the search beam Pertin carried was rapidly receding before Babylon could get squared away.

As his arms flailed, his wrist passed before his eyes and he caught a glimpse of his watch. He looked again, then swore in disbelief. Less than ten hours had passed since he had emerged from the tachyon transporter! Less than a week, really—never mind whatever time he spent as a stream of coded pulses between Earth and the orbiter—less than a week since he had been quietly taping Old Poly­nesian in the Southwest Pacific, with no worry greater than whether there would be fresh pineapple again at lunch. It was incredible. There had simply been no warning, no hint anywhere in the world he could see that he was about to be ‘ thrust into this mad adventure, played for stakes he did not understand, against opponents he did not know.

And meanwhile he sailed down immense black corridors on the trail of the winking flare of the Scorpian robot.

When he caught up with the party they were clustered around a narrow doorway that led into a vast black room. Pertin was expostulating with the Scorpian, to no avail. The robot rapped a contemptuous dismissal, and sailed into the blackness. The hot blue arc on its tentacle flooded the room with harsh light and the three terrestrials peered in­side.

What they saw was a hollow globe, with a bridge across it. At the center of the sphere the bridge widened to form a

disk rimmed with structures, faced with dials and knobs and buttons, patterned with strange symbols. Doc Chimp chattered nervously, “Are we going in there, Ben Line? It looks awfully strange to me!”

Pertin shrugged. “I think he’s found the right place,” he admitted grudgingly. “God knows how. That Scorpian knows more than he ought to! When we get back to the orbiter I’m going to have a lot of questions—questions about how this thing came to be and how it was destroyed. If it was an orbital fort, brought down by military action, was it maybe manned by mutineers against whatever rules Cuckoo? What sort of beings were involved? And what was their quarrel?”

“Mighty big questions.” Doc Chimp jumped and clutched a metal bar three meters above the bridge. A rail­ing, maybe, if giants had walked it. He clung there, squint­ing uneasily into the dark ahead. “Don’t ask them too fast. I think the answers could kill us again.”

Babylon pulled his shoulder pack forward and started his own set of omnirecording instruments. Doc Chimp’s might be adequate, but he chose to take no chances. There was no knowing what this race had used for communication— sound, modulated light, radio, perhaps even gamma-ray signals; the recorder would sample everything.

The rap of the Scorpian robot interrupted him. “Desist!” his Pmal rattled. “I have not instructed you to record.”

Babylon looked up at the shining hulk of the robot, which had flashed back toward him and hovered omi­nously overhead. “I’m doing my job,” he said.

“Correction! Language specimens of second priority! First priority assigned to technological data, emphasis weapons systems!”

Babylon felt a sudden rush of fury. “You idiot,” he snapped, “language is why I’m here! I know nothing about weapons!” He stopped as Ben Pertin touched his arm.

“Let me handle this, Jen,” the other man said, and con­fronted the robot. “Buzz off,” he ordered. “We have an assigned mission and you’re only a hitchhiker. We’re look­ing for records of some sort, not weapons.”

The robot hovered silently, its thoughts unguessable; then, without responding, it flashed away. “Oh, how I loathe that thing!” Doc Chimp chattered. “Come on, Dr. Babylon. Do what you have to do, so we can get out of here!”

How far all this was from the orderly acquisition of knowledge in some library or among some distant tribe! Jen Babylon could not believe that he was. here, in this ancient vessel, on this incredible world. Yet his reflexes worked as well as in Cambridge or on Moorea. He found himself in­volved in the puzzle of what, for these long-dead people, had constituted a language. The more personal puzzle of what was going to happen to him next remained outside his focus of thought. They sailed through immense black corri­dors, dived into pits of black mystery, emerged along the bridge that widened to form a disk. All this Jen recorded on his instruments and fed into the emerging pattern in his brain: the language, then, was not wholly unlike human, in that it used graphic representations (the markings on the instruments) and sound modulation (the challenge at the entrance) to convey information. That was pure profit! It could have been much harder.

Somewhere in the shadows they saw the robot’s hot blue arc, cutting into something or carving something away; Babylon shuddered at the thought of what forces it might be releasing, but did not hesitate. He reached out and touched the devices before him …

They were still alive! A dial glowed. Shadows began to flicker across the dark curve before him. “Oh, Dr. Baby­lon,” whispered the chimp beside him in awe, “we’re look­ing outside! Those are the towers!”

They were; the picture shook and then firmed itself. Babylon could make out the angular outlines of the crystal mountains—or crystal beings—around the wreck, and the vast swath it had cut when it fell. Squinting upward, he caught a pale shimmer of color, clearly the luminous sky of Cuckoo; but beneath them was only darkness shot with brief flares of scarlet and gold. “It’s the control room, all right,” he said. “The walls are a screen to show everything around—damaged now, I would guess, so that only part of it works. Help me find a readout or tape speaker—some sort of records!”

“I don’t know what to look for, Dr. Babylon,” the chimp complained.

“Neither do I! Use your brain!” The chimp turned away dolefully; Pertin was already touching, peering at, even smelling every object in sight. It was not even physically easy. Babylon decided that the operators of the ship must have been twice human height, and their hands must have had no human shape; everything was uncomfortable and unfamiliar. From the doorway Doc Chimp chattered:

“Look here, Dr. Babylon! There’s stuff missing!” There was a thing that might have been a cabinet, but its shelves were empty. “Somebody else got here ahead of us! Oh, Dr. Babylon, what do we do if they come back?”

“Oh, come off it, Doc,” Babylon snapped. “It was prob­ably ten thousand years ago—anyway, what do you sup­pose these things are?”

It was a rack of slim black hexagonal rods, neatly stacked on spindles on a massive block of something slick and black. Each hexagon was patterned along one face with markings that could be nothing but writing. Babylon gently pulled one off its spike. It was light enough to be plastic, strong enough to be steel, and apart from its mark­ings totally featureless.

It was Doc Chimp who found the answer to the puzzle. “That slot,” he chattered. “Wouldn’t one of them fit into it?”

They clustered around, peering at the six-sided slot in the corner of the block. They did not have to speak; Baby­lon knew the same thoughts were in all their minds: tape recorder of sorts? Or weapons-arming system? Or self-destruct commands? Or something wholly unguessable?

There was only one way to find out. Babylon slid one of the hexagons into the slot before either of the others could object.

There was a soft chime, and the block became semitransparent. Swirling plumes of colored light moved within it.

Babylon bent to his instruments, and the Pmal monitor beeped instantly. “Receiving apparent signal,” it whirred. “Wave shapes indicate high-order complexity. No apparent match in database.”

Babylon pulled the hexagonal rod out of the slot, and the colors died. “I think this is what we came for,” he said. “I don’t know what it is—ship’s log, maybe; maybe porn shows for the crew—who knows? But it’s some sort of cor­pus, in some sort of context. If we can get it back to far- link I think I might be able to reconstruct it.”

“Get what back?” Pertin demanded. “Those sticks?”

“All of them—and the block, too.”

“Jen! That’s got to weigh hundreds of kilos!”

“Do you have a better idea?” Babylon demanded.

Pertin stared glumly at the block. At last he sighed. “Guess we’d better get that damned Scorpian back with his torch; that thing’s never going to come loose any other way.” He tugged at the block experimentally. “Nope. Part of the structure. And how do we know that cutting it free won’t ruin it? And even if we did—”

But while Pertin was talking, Doc Chimp was tugging and poking and prying; down at the base of it he was pok­ing his long fingers into unfamiliar recesses, and something clicked. The chimp shoved at it with his skinny arms, and the whole block came ponderously free.

Babylon exhaled a sigh of relief. “Thank God for small favors,” he breathed. “Now we just—”

A dull explosion stopped him.

For a moment he thought the recording device had been booby-trapped, but Pertin snarled: “That crazy Scorpian! He must’ve bit into something that bit back! I’d better find out what he’s up to—and then we’d better get the hell out of here!”

The block would have weighed half a metric ton on Earth, but here its weight was only a few kilograms. Nev­ertheless, it had its half-ton of mass. When Babylon and the chimp pulled it out of place, it moved slowly at first, like a half-ton ice floe afloat in still water; but then it kept coming with inertia that would not be denied. They man­aged to get it moving back in the direction from which they had come, just as Pertin returned with the Scorpian’s bright light visible far behind. “He found his damn weapons!” Pertin yelled, half sobbing and half laughing, “and much good it did him! The idiot blew himself up. He’s going to be damn little use getting back with this stuff!”

Babylon cut his thruster, panting, as the massy block for a moment seemed willing to go in the right direction. “He can’t help us?” he asked in dismay.

“He can barely help himself—and he’s got a thousand kilos of bits and pieces that he’s pulling along. Come on! Let’s get this thing back to the ship if we can—the Scorpian’ll have to take care of himself!”

If we can . . . The outcome was in doubt. The three of them attacked the block like pilot fish nudging a shark, and slowly, slowly they made their way back through the ship, back out the entrance port, with the distant howling of the crippled Scorpian always behind; and then the trou­ble had only begun. Moving the mass was easier out in the gloomy canyons walled with those broken pillars of pale and shifting light, but the towers were not wholly quiescent now. They woke more quickly, fired their Jovian bolts more accurately. A dozen times before they were clear of the towers the lightnings struck close enough to leave them gasping and tingling.

With the line of flight reasonably clear, Doc Chimp, complaining vigorously, was sent back to help the Scorpian. The two parties arrived at the ebony plain almost together, the chimp gibbering frantically, “Ben Line! Dr. Babylon! Please, wait for me! Don’t leave this old monkey in this spooky place!”

In the faint light from the luminous, distant sky, Baby­lon could see that the robot had been sorely stricken. There were great gashes in its shiny surface, and the steam jets puffed only weakly and at strange angles; but it would not relinquish the net of objects it was bringing home. The

chimpanzee had a net of its own, larger than Doc Chimp himself.

And then Ben Line Pertin cried out in dismay: “The lander! It’s been hit!”

Clearly the towers had not suspended their attack while the party was in the ship. The lander’s scoops lay bent, scorched, half-retracted on the ebony velvet sand. There were great rents in its hull; the pilot window was shattered; fuel had leaked and burned out of split tanks.

They would never get back to the orbiter in that.

A wartime sailor of centuries before, seeing his torpe­doed ship go down in the middle of a shark-filled, stormy sea, must have felt as Babylon did at that moment. It was their link with the real, gentle world outside; and it was gone. “Jen!” Pertin roared in his ear. “Don’t daydream— get inside!”

“For what?” Babylon managed; but Pertin did not an­swer, and then his hands were full. Pertin was already dragging himself in through the shattered hatchway, tug­ging at the unwieldy block from the ship. Babylon guided it, flailing desperately out of the way as one corner of it threatened to crush his foot between its own bulk and the fabric of the lander, and then they were inside. To what point, Babylon could not imagine. The thing would never fly! Its shattered hull might protect them for a brief time, but when the lightnings found them again it would be all ‘ over for it—and them.

And one struck almost at once. Babylon’s muscles con­vulsed in a tetany of shock. Not more than a millionth of the energy of the discharge flowed through the hull and into him, but it was the worst pain he had ever felt. Dizzy and shaken, he felt himself thrust out of the way by the skinny arms of Doc Chimp, crowding in behind him. “Oh, Dr. Babylon,” the chimp chattered, “what a terrible place this is! And now what?”

Pertin snapped brutally, “Shut up and help me with this stuff! You too, Jen! Come on!”

“What’s the use?” Babylon demanded, but no one took the time to answer. Pertin was opening a gate in a locker behind the control couches, now smoldering faintly, and the chimp was thrusting the great block toward him. Cryp­tic lights raced and flashed in patterns over the gate, and Pertin exhaled a sigh of relief. “Get the damn Scorpian, Doc!” he ordered, tugging at the block from the ship. “Give a hand, Jen!”

Another bolt smote the ship, stunning Babylon. Doc Chimp rolled back into the lander on the heels of it, shoe- button eyes rolling in terror, chattering with fear. “Here he is, that clanking mass of “confusion,” he gasped, as the Scorpian limped slowly after him, “but what we need him for I’ll never know.”

“Just shut up and bear a hand!” Pertin was opening the gate again—

For a moment Babylon’s heart had leaped with hope— he recognized the box at last, a tachyon transmitter, their one remaining hope of escape. But when the gate opened and he saw what was inside, the hopeless anguish closed in again. The block was still there! Unchanged! The machine obviously had been too damaged to work, and they were doomed!

Queerly, Pertin and the chimp were pulling the block out and shoving the robot’s bag of tricks in its place—glinting crystal rods and disks, ebon artifacts of geometrically strange shape, hexagons like the ones Babylon himself had brought. “But—but it’s not working!” Babylon objected feebly.

The chimp stared at him, incredulously. Pertin did not answer: the lights flashed, the door opened again, the two wrestled the net sack out and turned to Babylon. “You next!” Pertin ordered.

“But—for what—”

“Dr. Babylon,” the chimp chattered pleadingly, “will you get in?”

Unwillingly, Babylon bent himself double and allowed himself to be squeezed into the chamber—helped, at the last, by Pertin’s firmly shoved boot. He felt the door slammed upon him.

For a timeless moment he was crushed into an unbear­able position, in a chamber without light or air—

And then the door opened again.

He was dragged out by a creature that looked like a fig­ure poked out of dough, sprouting tentacles that gripped him and pulled him free. The gloom of the wrecked lander was gone; he was in a harshly bright metal chamber, and as the Sheliak released him he flew across it and slammed into a wall.

He was alive. He was on the orbiter. Somehow he had been saved.

That was the greatest wonder. He was alive.

Dazed, Jen Babylon caught a cable and hung against the wall as a squirming, flailing Doc Chimp sailed at him, col­lided, scrabbled for a hold. Arms and legs grappling the cables, the chimp panted, “We made it, Dr. Babylon! Oh, this poor old monkey never thought he’d see this place again! Watch out!” Behind him, the smoking hulk of the Scorpian robot soared out of the tachyon chamber and crashed against the wall. It made no attempt to grasp a hold, and its jets steamed at random; it floated slowly out toward the middle of the chamber.

And that was all.

Doc Chimp moaned softly beside him and sprang out toward the chamber. There was a quick exchange with the doughy Sheliak, and then the chimp launched himself back . to the wall, his face working with woe.

“Oh, Dr. Babylon,” he sobbed, “poor old Ben! That’s the last of us. He didn’t make it.”

Babylon stared at him uncomprehendingly. “I—I don’t see how any of us did,” he managed.

The chimp’s sobs turned into what was almost a giggle. “Tachyon transmission, Dr. Babylon,” he said. “That’s all. Confuses you, doesn’t it?—but I thought you’d know, seeing you just came all that way from Earth.”

“But the machine didn’t work! I saw Ben take the block out again!”

“The original of the block,” the chimp corrected. “It’s still there, though the duplicate’s here—probably slagged to a cinder by now, just like poor Ben. Just like the originals of you and me.”

Babylon stared at him with horror. “Us?”

“The ones that stayed behind,” the chimp explained, and giggled hysterically. “So you’re beginning to understand, Dr. Babylon? And now you know how it feels! What it’s like knowing you just died, ten thousand kilometers away!”

It was more than ten thousand kilometers.

The lander was a smoking ruin. That other Jen Babylon lay half stunned, with the dead body of the chimp behind him at the shattered door of the transmitter and the wrecked Scorpian robot lodged queerly across his legs, waiting for the final bolt that would end his pain. Had he made it to the orbiter? Did some “he” still live—somehow, somewhere?

His last thought, as the final bolt caught him, was that, even if the answer was yes, it did not ease the terror or the pain.


Something wakes me …

Is it time?

I stretch out in my sleep and taste the troubling emana­tions from my watchers and my slaves. A ship has been invaded, an invader wiped out. There is nothing there to justify disturbing my sleep. But it is troubling.

I reach out to the farthest of my watchers and my slaves. One is floating in the all but liquid air of a giant planet With a ruddy, dark sun; one moves about a queer old city, far from her crustacean slaves; one has died on the surface of a cratered rock in the heat of a blazing star.

There is nothing to trouble me in any of this, or in any of the others. But I am troubled.

I have been troubled before by stupid slaves, by fools forgetful of their origins and their destiny, by craven idiots who rose against me, thinking to destroy even HIM. They were themselves inevitably erased. HIS misguided enemies have forever been erased and forever will be, with no need to disturb HIM. Until HIS time, there will never be trou­ble. There cannot be, for HIS plan allows no trouble.

HIS time? Is it near?

I reach out to every slaved being and instrument, and I find nothing. It is not yet time for HIM.

But soon.

I return to sleep, and to the waiting of many million years.


“I give you greeting,” said a voice in Jen Babylon’s dreams. He struggled against waking up, failed, and opened his eyes.

Hanging in the air in front of him was a creature with five oddly placed eyes in a bat’s gnarled face, supporting itself on filmy wings. “I am Mimmie, Dr. Babylon,” said the creature through the Pmal translator by Babylon’s head. “I am familiar with your work on linguistics and wish to associate myself with your efforts.”

Still more than half asleep, Babylon said automatically, “Good morning.” He pushed the restraining webs of this place he had slept in aside and sat up, catching himself just in time as the muscular effort almost flung him across the sleeping chamber … and memory flooded in.

“It is known,” the creature went on remorselessly, “that Earth sapients have prolonged start-up periods after power- down status. Query: Are you functional?”

Babylon straightened out, grasping one of the catch- cables and reaching instinctively for his glasses. His ears were still ringing, and he felt a stiffness in his joints that had not been there before coming to this strange place. “If you mean am I awake, yes.” Not finding the glasses, he remembered they were no longer necessary.

“Disjunct, Dr. Babylon,” the creature said politely. He had already recognized it as a T’Worlie, that oldest of space- going races, the ones who had originally discovered Cuckoo. Perhaps the T’Worlie he had met before. From it a series of pungent, not unpleasant aromas wafted: a vinegary scent of curiosity, burnt-honey of controlled impatience, coppery concern. “You seem perturbed.”

Babylon said bitterly, “I guess you could call it that, yes.”

“Confirmation,” the TWorlie agreed. “You are con­cerned over recent happenings on surface.”

“Wouldn’t you be? One of my oldest friends dead—”

“Reference is assumed to Ben Pertin,” the TWorlie piped. “Understood. Offer ameliorating data: There is no shortage of Ben Pertins in vicinity of Cuckoo. Fourteen-plus known specimens, at least three surviving.”

Babylon shook his head, incredulous. How could one re­late to these creatures who took life so lightly? Even the humans like Ben—like the late Ben—himself? Much less this thing that floated before him.

Still, the situation was interesting. His scholarly mind awoke to curiosity. Babylon had learned some of the TWorlie scent vocabulary as a part of his graduate studies. But to sniff the stoppers of tubes in the linguistics lab at the university was no real analog to the presence of a crea­ture sending them out in waves of feeling. Babylon shook himself, dismissing the burden of worries and fears as best he could. “Did you say you wanted to help me?”

“Confirmation. Mimmie, deceased, was our race’s great­est linguist, Dr. Babylon.”

“I see. And you studied with, uh, this Mimmie?”

“Negation, Dr. Babylon. I am identical with this Mim­mie. I am Mimmie.”

“Oh, I see. You’re a tachyon copy,” Babylon said, feel­ing an embarrassment that he could not account for.

Garlicky waves of amusement came from the TWorlie. “Confirmation. I am tachyon copy of Mimmie. You are tachyon copy of Dr. Jen Babylon.”

Babylon was startled, but then he grinned. “Right you are, Mimmie. As you say, Earth sapients have prolonged start-up periods after power-down. IH be pleased and hon­ored to work with you. Do you want to get started?”

“Disjunct confirmation, Dr. Babylon. Confirm that I want to get started. Potential negative feasibility of doing so. Council meeting has been requested with you in atten­dance concerning events resulting in loss of lander and dam­age to Being HG-87, Scorpian robot.”

Babylon was startled. “I’m going to be put on trial? When?”

“Negative trial, Dr. Babylon. As to time, twenty hours, error bar two hours plus or minus.”

“Great!” Babylon snarled. “I come all the way out here to do a job for somebody who gets himself killed in the process, I nearly get killed myself— Oh, hell,” he said, as the T’Worlie exuded a saffron scent of sympathy, “I guess there should be some sort of inquiry, after all. Twenty hours? Well. That’s a long way away; do you want to get started on the data I brought back?”

Since Pmal translators were a human invention, though greatly improved by technologies borrowed from other ga­lactic races, the T’Worlie was not entirely familiar with them; but with Jen Babylon working alongside he quickly joined in running through the first tests on the data from the wrecked ship.

Pmal translators operated in three separate modes: syn­chronic, diachronic, and morphological. For most human languages, the synchronic mode was usually enough. It only meant that the translator stored words and matched them against its library of known words. A sample of a few dozen lexigrams would allow it to recognize that the lan­guage was, say, from the Indo-European group rather than the Algonkian or one of the languages of Southeast Asia. Generally it could also instantly detect the rattle of Sirians, the tweeting of TWorlie or the half-dozen other principal galactic tongues. A few more words would generally cut between, say, the Germanic and the Latin; no more than a couple of sentences would allow it to determine that the language was not French or Portuguese or Romanian, but Italian, and then it was only a matter of discriminating the right dialect. From then on it deployed its database of lan­guages and grammars, and cross-mapping was easy.

Of course, it was not really that simple. Spoken lan­guages do not come in discrete packets of “words.” “Words” are a linguists’ invention. The analyzed sound trace of any spoken sentence shows breaks and fusions that do not correspond to the conventions of the written lan­guage. The Pmal circuits that learned to average out the actual pauses and redivide the sounds into the units of for­mal analysis were quite sophisticated; they were, basically, what made Dr. Linebarger’s translators work.

When the synchronic mode failed, the Pmal had the diachronic resource. It matched root words against its data­base of known protolanguages, looking for resemblances according to a complex algorithm of vowel and consonant shifts. It was this aspect of linguistics in which Jen Babylon was one of the Galaxy’s great experts. But it failed him now. The portable Pmal could not even make a beginning. Even the programs Jen Babylon had brought from Earth, now stored in the farlink memory, could find no analogs in any of the families or phyla or even macrophyla in the store.

Remained morphological mapping. In this mode the portable Pmals were very slow, and even Jen’s own pro­grams pored over the possible match between sounds, col­ors, and rhythms of the data taped from the block, match­ing them against hypothesized events and phenomena, for hours without result. The T’Worlie fluttered away, and re­turned with a Sirian eye tugging instruments of its own to Babylon’s workplace …

And another blank. None of the known languages or dia­lects of the Galaxy matched in any way to the phonemes, symbols, or structures of the unknown tongue. Or tongues.

Or gibberish.

After eighteen hours of trying to decide which, Jen Babylon was exhausted. When the skinny form of Doc Chimp peered around the doorframe and asked, “All right if I come in, Dr. Babylon?” he suddenly realized how tired he was.

“Certainly, Doc Chimp. But I was just thinking of going to sleep. Maybe a night’s rest will give me a clue about this language.”

“It hasn’t been working out?”

“Not in the least, Doc. There is no great galactic lan­guage cognate to it, both Mimmie and I will attest to that.”

“What a shame,” the chimp said sympathetically. “I sup­pose, of course, you’ve also tried matching against the na­tive languages of Cuckoo? Well, certainly—”

“Native languages?” Babylon repeated.

“—certainly you have, you don’t need a dumb old mon­key to tell you that\ Please excuse me, Dr. Babylon.” The chimp looked embarrassed at his own presumption. “How­ever,” he said, “that’s not why I’m here. I thought I’d bet­ter take you to the hearing myself—this place is so confus­ing!”

“Hearing?” Babylon realized how fatigued he was; all he could seem to do was repeat what Doc Chimp said. And then he remembered. “The hearing!”

Doc Chimp nodded, his little shoe-button eyes worried. “I wish you’d been able to get a little rest first,” he said fretfully. “To make a good impression, you know. Al­though this isn’t anything serious—don’t misunderstand me—or at least it shouldn’t be. Although the way things are going now, you never know what’s going to be serious and what isn’t, and that’s the truth, Dr. Babylon!”

Babylon took a deep breath, and pulled himself together. The inquiry meeting had escaped his mind entirely, and now that it was at hand it began to seem worrisome indeed. If only Ben Pertin were here to advise him!

But he wasn’t, and that was that. “All right,” he said. “Just let me speak to Mimmie first.”

The T’Worlie was hovering politely a few feet away. “You wish me to proceed with the matches of the Cuckoo tongues in your absence,” it trilled, and the Pmal conveyed the English words. “Confirmation, Dr. Babylon. Will do so.” And it fluttered away to the instruments, leaving a frying-bacon scent behind that Babylon recognized as laughter.

It was the first real chance Jen Babylon had had to look around the orbiter. The shock of the death of his own du­plicate, the rising concern about the council meeting he was about to face, even his fatigue were set aside as he rubbernecked like any tourist. So strange a place! he thought as he launched himself after the chimpanzee from one handhold to another, and: What am I doing here, any­way?

But there was no answer to that.

They shot through corridors, drifted across open com­mon rooms. Babylon had expected to see more beings than were in evidence. They encountered only a few; but what a few! Another of those doughy shape-changing creatures called Sheliaks, a great blue Sirian eye, with little crablike pincers hanging below the orb, passing them with a ripping sound of electrostatic force, a silvery cloud of insectlike creatures that he recognized as Boaty-Bits. Once he saw four or five actual human beings, working over a dismem­bered copper-colored machine. He almost called to Doc Chimp to pause so that he could speak to them, when he noticed the telltale opacity of expression and incipient locomotor-ataxia gait that told him they were Purchased People. Convicts, who had been bought as proxies by crea­tures so alien that they could not survive in oxygen-bearing air, supporting a water-based chemistry. He wondered if any of the group who had been transmitted with him were among them, but recognized none.

Doc Chimp was cowering at an intersection, gesturing frantically to him to stop.

Babylon caught a handhold with flailing arms, started to speak, saw the pleading look in the chimp’s eyes, and de­sisted. There was a droning, malevolent sound growing in the next corridor; it peaked, a triangular shape shot swiftly past, and the chimpanzee sighed. “That’s a deltaform, Dr. Babylon,” he whispered. “They’re the worst of the lot. I just didn’t want him to see us here.”

The little ape’s shoe-button eyes were dull, and his fur seemed bedraggled; all the cheerfulness with which he had come to meet Babylon was gone. “Why shouldn’t we be here?” he asked the chimp. “I was summoned to the meet­ing, after all.”

The chimp coughed apologetically, lifted his kepi, and scratched the hairy scalp beneath it. “Well, that’s what I was just getting around to telling you, Dr. Babylon,” he said. “The meeting’s not for almost an hour yet. We’re going to make a little stop first. We’re almost there,” he added, pushing himself away and across the broad corridor. Babylon pursued hastily.

“Where’s ‘there’?” he demanded of the retreating chimp.

“It’s Ben Line’s room,” the chimpanzee called over his shoulder. “Real nice place, too. Old Ben came here years and years ago, you know, so he got first pick of quarters. Fixed it up to suit himself.” He caught a holding strap and hung by the side of the passage, just outside a door, until Babylon caught up with him.

Babylon clung to another strap, looking around. It seemed almost ghoulish to be going to the room of his dead friend. “Why are we doing this?” he panted. “Couldn’t it wait till after the meeting?”

“I don’t think so,” the chimp chattered nervously, look­ing up and down the hall. “You’d better go inside now, Dr. Babylon. This is the place.”

Babylon hesitated. “I really don’t see why—”

“Just go in, Dr. Babylon!” said the chimp, doing some­thing with the door. As it slid open he caught Babylon’s shoulder in his astonishingly strong hand and gently thrust him inside.

The door closed behind him.

The room Ben Line Pertin had slept in was dimly lit, but Babylon could make out the shape. It was a good deal more homey than the bare cubicle Babylon had been given: a faceted, polyhedral enclosure, with most of the interior faces covered with flat photographs of scenes from his life. Next to the entrance was an exterior shot of the great orbiter Sun One, where Ben Pertin had first been transmitted from Earth. Over his bed loomed the immense majesty of a mountain that, Babylon knew, had been the grave of several Ben Pertins; it was called “Knife-in-the- Sky” in one of those Cuckoo languages that, Babylon re­membered to hope, the T’Worlie was now feeding into the great Pmals. And, in the bed—

In the bed something was moving. A figure sat up and peered at Babylon, and a familiar voice said, “Well, Jen, about time you got here!”

In astonishment, Babylon lost his grip on the handhold. “Ben!” he gasped. “But—but you’re dead.”

Two of the facets of the cubicle glowed a little more brightly, as Ben Pertin turned up the lights of his room. “Why, I guess I am, a lot of me,” he said bitterly. “Grab hold of that strap, for God’s sake. Else you’ll be bumping all over the place.”

Babylon flailed around until he caught the end of the holding strap and pulled himself back to the wall, still un­able to take it in. “You’re a tachyon copy,” he guessed.

“Well, sure—what else? We all are. But if you mean I’m not the Ben Pertin who got blown away with you down by the old ship you’re wrong.”

“But we left you there!”

“Yes, you did,” Pertin agreed moodily. “Oh, I’m not blaming you—after all, I pushed you in ahead of me. But I have to tell you I didn’t like it, after you’d all gone and the tachyon transmitter shorted out. Still, that’s all water under the bridge now. The important thing’s what we do now.”

He sat up, and for the first time Babylon realized Pertin was not alone in the bed. A slower stirring on the far side of the coverings produced a female human face, which stared at Jen Babylon without speaking. “Excuse me,” Baby­lon said automatically.

Pertin scowled. “For what? Oh, you’re looking at Doris.” He laughed. “Don’t worry about Doris; she’s a Purchased Person. Her owners have this academic interest in human sexual behavior, so sometimes when things aren’t busy for them they let me borrow her for a while. And sometimes I need to, believe me. Never more than when I finally got the transmitter fixed and got back here!” He threw the covers off; the movement half buried the woman, who seemed not to mind, perhaps not even to notice. “But that doesn’t matter,” he said sharply. “Listen, Jen! I told Doc

Chimp to bring you here without saying anything, because out of all this trouble we’ve got a good break!”

“What’s that?”

“No one knows I’m here!” he cried triumphantly.

Babylon pulled himself over to a more comfortable posi­tion—more comfortable mostly because it hid the bright, empty eyes of the woman named Doris. “I really don’t see why that is going to help us translate the language,” he said.

“Not help us translate. Help us get this place straight­ened out!” Pertin snapped. “As long as they don’t know I’m here I have freedom of action, don’t you see?”

“To do what, exactly?” Babylon demanded.

Pertin hesitated. “Well, that I can’t say, exactly,” he ad­mitted. “What I know for sure is that some of them are out to wreck this place—even destroy the whole of Cuckoo! And, no, I don’t know which ones. Not for sure. The Scorpians, yes, almost certainly. The deltaforms—I wouldn’t put anything past those bastards! I don’t think the TWorlie are in it, or the Sheliaks, either, although there’s always a chance of an aberrant individual in even a friendly race—”

“Ben,” Babylon said patiently, suddenly feeling a rush of sympathy for the worn, harried man who had once been his friend, “are you sure you’re not imagining all this?”

Pertin scowled at him. “You’re not one of those aber- rants yourself, are you?” he demanded. “No, of course not. Sorry. But you just don’t know what it’s like here. Some­times I even worry about Doris, although her owners have never, ever shown any interest in the politics of what hap­pens here; they’re just curious, want to observe without tak­ing part. I even worry about the Doc. No. Don’t think I’m crazy, Jen—even if I am. I know I’m not crazy on the subject of some of these creatures wanting Cuckoo de­stroyed, and you and me with it!”

He flung back the cover, launched himself across the chamber to a cupboard, began pulling out fresh clothes. “While you’re in the meeting, I’m going to look around. The worst ones are sure to be at the meeting—they only convened it to embarrass you and Doc Chimp, and any other friends of mine that might still be around. Say! I wonder! Do you suppose they could have arranged it so I’d be left down there to die? —No, I suppose not; but they would have if they could!”

A thought was insistently forming itself in Jen Babylon’s mind, and the word that summed it up was paranoia. What did you do with a man who had gone over the edge? Heaven knew Pertin had every reason; but that did not make it easier. He said gently, “You know, Ben Line, I think you ought to rest a while longer.”

“Don’t call me that!” Pertin spun to glare at him. “Ben Line Pertin’s dead down there in the lander. The one you’re talking to is—is—is Ben Omega Pertin. The last of the Ben Pertins—and maybe one too many, at that!”

The situation was getting to be more than Babylon could handle, exhausted as he was, with his mind full of a hundred other concerns. A scratching at the door rescued him: Doc Chimp, leathery face poking in timorously, warning that it would not do to keep the meeting waiting. Fortunately it was only a short distance, but Babylon found time to say a word to the chimpanzee as they brought up before a larger, more official-looking door than any he had yet passed through. “Hold on a second,” he panted. “I’m worried about Ben!”

The chimp poked its muzzle at him in what would have been a pout if he had had lips. “You’re worried, Dr. Baby­lon? What do you think I’ve been, all this terrible long time?”

“Well—isn’t there a medical service here on the orbiter? Some sort of psychotherapy?”

Doc Chimp looked puzzled. “What would Ben want therapy for, Dr. Babylon? Any more than any of the rest of us, I mean? … Oh, I see!” The leathery lips split in a grin. “You think he’s having delusions about the wicked­ness of the deltaforms and the Scorpians and all those other beasts and buckets of junk! Wish it were true, Dr. Baby­lon! I’m afraid he’s sane as you and I where that’s con­cerned—maybe a lot saner! Now,” he said, reaching for the door, “spruce up your posture and put a smile on your face! Make them think you’ve got the Galaxy by the tail and you’d just as soon as not swing it out past Andromeda! ‘Cause if you let them think for a minute you’re weak or scared—then you’ll find out just how evil those beings can be!”

The room was huge and irregular, and it seemed to be packed with creatures and—things! Some he recognized, others not. A furry, big-eyed kitten-shape purred on the fat black cushion of its life-support system. A slithering eel­like shape squirmed restlessly in among and behind the other creatures, with tentacled eyes that thrust themselves in all directions. Babylon caught his breath. There was a creature that was the surest shape of a nightmare, clad in armor that glittered slimily like an insect’s chitin, black on its back and scarlet on its belly; its eyes were multiple globes of greenish jelly, and it had yellow, leathery wings. It was staring directly at Babylon, and without volition he moved away. And that was only the beginning: a pair of T’Worlie, a silver hive of Boaty-Bits, three Purchased Peo­ple, a soggy-dough Sheliak—and, yes, there was a Scorpian robot. No, wrong. There were two of them, but one was stripped down, most of its casing removed, the propulsion system dead. It traveled on the back of the other one like a papoose. There is no easy way for a human being to tell one mass-produced Scorpian from another, but Babylon was sure that the one being carried had been his compan­ion down below.

There was a racket of drumroll, squeak, shriek, and yowl as he came in, but the sound stopped. Everyone turned and stared at him, and Jen Babylon halted, gripping a handhold, for the first time aware of just what sort of council he was dealing with.

Doc Chimp, entering behind him, saw his hesitation and moved to ease it. He launched himself toward the center of the room, thrusting one long, skinny paw against Babylon’s shoulder and stopping himself with a recoil-less collision against the Sheliak. “Let me introduce you!” he shrilled, hanging lazily in midair with the red flaps of his vest flying like small wings. “Folks and gentle beings, this is Dr. Jensen Babylon, our planet’s most distinguished expert in quantum-dynamic linguistics—and not unknown to members of his craft throughout the Galaxy. Even herel He has come to risk his life for us—even to lose it, now and then, as so many of us have. Bid him welcome, beings all!”

The uproar broke out again, dominated by a roar of sur­prising volume from the kitten-shaped creature on the black hassock. Babylon’s Pmal translated: “Terrestrial monkeys behave like monkeys everywhere. Be still, pri­mate, for significant business of this council!”

Doc Chimp licked his lips, but faced the kitten bravely. “True,” he chattered, “I am only a humble monkey, and no one cares for me. But no one cares about any of us here. We go to our many deaths without hope of reward. Yet be of good cheer! With terrestrial primate brawn and ter­restrial primate courage to help you, you may yet—”

“Be still!” the growl thundered. “Babylon! Why are you here?”

It was not a question Jen Babylon had expected. The only true answers were that he didn’t really know, and cer­tainly had never desired it, but Doc Chimp was glancing at him nervously and he saw that the little creature was ac­tually trembling. He temporized. “I thought this meeting was to discuss the wreck of the lander,” he said.

Uproar of many queer voices again, with the kitten’s basso purr breaking through: “It is to discuss you, Dr. Jen Babylon. We have no use here for quantum-dynamic lin­guistics practiced by primitive races. You are a waste of scarce resources! What makes you think this language can be translated? Suppose the creatures who spoke it do not think of the world the way we do? Suppose their interests are internal? abstract? mathematical? Suppose their mode of communication is telepathic, or evocative, or—”

Suddenly Babylon was fed up. “Suppose you shut up,” he snapped. “It’s obvious that your race is among the prim­itive ones in this respect! Look. What do you use lan­guage for? To communicate. What do you communicate about? Matters of mutual interest. Without the mutuality there is no communication—not because the language fails to conceptualize the material, but because the material it­self is not mutual—”

He paused, because Doc Chimp was shaking his head worriedly. “At any rate,” he went on after a moment, “I have confidence that I can untangle the language, far-link will help. If necessary I’ll send tapes back to my lab—to the laboratories in Boston for analysis by the main­frame equipment there. Trust me, we’ll get it solved,” he said, aware that he was trying to placate this group of un­pleasant personalities.

A rattle sounded from the whole Scorpian, translated by the Pmal as harsh laughter. “Negative trust,” it said. “De­fer decision on ‘solved.’ Not relevant in any case. Entire project, also entire function of investigation of ‘Cuckoo’ ob­ject, as well as ‘Cuckoo’ object itself, of no further impor­tance. Recommend termination.”

The meeting went on beyond that, but Babylon under­stood little of what was happening. The galactic creatures seemed to have had the practice of the disorderly assem­blies long enough that they could understand what was going on. Or more likely, didn’t really care. Babylon had not. When all of them were chirping or buzzing or thunder­ing at once, the Pmals were swamped. Only fragmentary phrases came out, in disconnected order.

Yet when they were outside Doc Chimp said moodily, “Well, I think it went well enough, Dr. Babylon—”

“Jen, please.”

“—Jen, but you never know with these creatures.” He tugged Babylon out of the main corridor into a smaller one, heading back toward their own quarters of the orbiter; a flight of T’Worlie fluttered out of the way, exuding a quick barnyard odor of mild annoyance. “But maybe you’d better do what you said and get your other self back on Earth to help. We may not have very much time.”

“All right,” Babylon said, gasping with the effort of trying to match the chimpanzee in tug-and-kick along the corridors. “I don’t see what the hurry is, though.”

The chimp paused, grabbing a handhold with one skinny arm and snatching Babylon in midflight with the other. He glanced up and down the corridor, his face stiff with worry. “You don’t?” he whispered softly. “I thought you were listening, inside there. Didn’t you wonder what that Scorpian meant by ‘termination’?”


He should have taken the subtrain to Cambridge, but he wanted the exercise. Now the weather had turned wet and cold and the wind whipped raindrops up the Charles River. Jen Babylon shivered and tried to walk faster across the bridge.

That was hard to do, because there were knots of people standing about, staring at the water—strange time for rub­bernecking! Babylon stepped down off the sidewalk to pass one milling cluster, coming perilously close to the rushing stream of hovertaxis and vans, and an elderly woman stepped out ahead of him, coming toward him. “Careful!” he snapped, rescuing her from the traffic lanes.

“Oh, sorry,” she said, putting her hand out to reassure herself by touching him. “Ugly-looking things, aren’t they?”

Not knowing what she was talking about, he nodded, slipped past her back onto the sidewalk, and found himself in a clear place. He glanced over the railing at the water, and then he saw.

The river’s edge was alive with huge, glass-bodied crabs.

The woman had certainly been right; the ugly things sur­rounded the water-filtration plant like scuttling crustacean ghosts. Babylon imagined he could hear the clicking and slithering even on the bridge, though it was impossible, of course, with the traffic so close behind him. Filthy crea­tures! And more and more of them all the time, appear­ing at shipyards and LH-storage facilities, stopping traffic on main arteries and even threatening the tachyon- transmission center. The authorities first tried to control them, then to destroy—explosives, flamethrowers, clubs, even by running Army tanks and road rollers over them to crush them. But the beings were virtually indestructible. Men with hammers, they had discovered, could blind them by pounding their eyes into rubble, and then the creatures became immobile and could be carted away. But they mul­tiplied faster than one-on-one tactics could destroy them— in what way, no one knew. In the Middle Ages people be­lieved that mice were spontaneously generated in piles of unwashed clothing; now the best opinion anyone could give was that the crabs appeared automatically in shallow water. So much for the steady advance of scientific knowledgel

They were a problem—but not particularly Jen Baby­lon’s problem, and he had plenty of his own. A robot hover- taxi hesitated before him, waiting for a clump of pedes­trians to get out of the way, and Babylon gave up the thought of exercise and jumped in. His problems were waiting for him at the university. It was impossible to put them off forever—though, Babylon thought wistfully, what an attractive idea that was! It seemed impossible that only a few weeks ago he had been taping old native dialects on Bora-Bora, with no worry in the world except the hope of promotion and the demands of his work.

As soon as he got to his desk he tried one more time to confront the most personal of his problems by dialing Sheryl’s call code on the stereophone.

And, one more time, it was her recorded image that an­swered him, not herself. “I’m terribly sorry,” it said, “that I am not able to be here in person just now. I am occupied in higher work.” Higher work! Madness, Babylon thought, as the recorded figure paused. There was a look of exaltation on her gaunt, consecrated face. This was not the off­handed, faintly bored Sheryl who had been his bed com­panion for so many months. The real Sheryl was drawling and mostly amused, where this person was … obsessed; Sheryl was fastidious about her appearance and dress, while this person had thrown on the first garments that presented themselves, and her hair had not been washed, or even brushed, for days. In a sudden burst of rapture the figure whispered, “I Cry the imminent majesty of Cuckoo” … and vanished.

Babylon watched the image shatter into golden mist and fade away. He was sorely troubled. It was not as if he had any commitment to Sheryl. They had never talked of any permanent relationship, much less marriage. Yet—they had been lovers for more than a year, had shared more intimacies than merely the bed. Could he let her do this to herself?

Or—more to the point—did he have any way to stop her?

A voice from the doorway brought him face to face with the second of his problems: Dean Margaret Kooseman. “Oh, Jen dear,” she whispered, a sad smile of compassion on her weather-beaten face, “how terrible this must be for you. Such a sweet, pretty girl, to get mixed up with those horrid Kooks!”

“Yes, well, thanks, Margaret,” Babylon said gruffly, taking off his glasses to see her more directly. It did not pay to let Margaret Kooseman too far inside your private life. “What can I do for you?”

She came in and sat primly down beside his desk, re­laxed as she gazed around the room. In one corner the pro­cessor was turning pages in an old missionary’s dictionary of Hawaiian, inputting dialects to correlate against Baby­lon’s own, more recent data; in another, two different information-handling machines were purring to each other as they matched sounds against sense. “What a nice, or­derly person you are, Jen,” she said approvingly. “In this very disordered world, you’re priceless!”

“You’re very kind, Margaret. Is that what you came here to tell me?”

“And so direct and to the point, too,” she sighed, favor­ing him with a smile. “But you have to let me just breathe hard for a moment, Jen. I’ve just come from a faculty sen­ate meeting and, oh, the noise and argument there! You know what they’re like.” He didn’t, of course; plebes like himself weren’t allowed in. “And this time worse than usual. Those crabby things! We were given some samples by the Public Safety Commission to try to figure out what to do about them—and would you believe it, everybody wanted them? The veterinary medicine school said they were animals, Charley Kentwell said they belonged to him because they were silicon-based and therefore inorganic chemistry, the computer people claimed they were ma­chines—we had to give one to each of them to shut them up.”

“I wouldn’t have thought there was any scarcity of them,” Babylon commented.

The dean nodded enthusiastically. “You see what I mean? You’re always right to the point! But there’s more to it—somebody even suggested you ought to take time out from your very valuable work to study them, because there’s a chance that they come from one of the known galactic planets, and may have a language—”


“No, of course that was silly. I put my foot right down on that. Especially since I’m afraid you’re going to have to postpone all your other work for something else, anyway.”

So at last they were coming to the point! Babylon’s voice was almost shaking with repressed anger as he demanded, “What are you talking about?”

“Cuckoo, I’m afraid.”

“But I’ve already done what you asked!”

She nodded sadly. “Isn’t it terrible? One does so much, and then they always demand just one more thing from you. This time it’s a packet of data from Cuckoo.” She fished in her dispatch case and brought out a glimmering silver ball. “This is it—ion-coded, because there’s so much of it You’ll have to feed it into your databank before you can work with it. It just came from the tachyon station for you.”

“Margaret! My work with the ancient Polynesian dia­lects—”

“Yes, isn’t it a pity? But we can’t give you any more processor time, so you’ll just have to feed all that into slow storage and clear the machines for this. I know I can rely on you. That’s why, when I retire—”

“Give me the damn thing,” he said sharply, unwilling to hear those vague promises again. What a waste! At least an hour to clear the databanks of the ongoing material— another hour, maybe five or six hours, for the processors to assimilate this unwieldy mass of material from Cuckoo— and then God knew how many more hours and days of puzzling it over before he could get back to his real work.

She smiled and got up, coming around the desk to touch the top of his head with her dry lips. “You’re so good, Jen,” she sighed, setting the gleaming sphere gently on his desk. “And, oh, yes, there’s a message for you on the ste- reostage concerning this stuff.” She giggled. “It’s so funny, really—it’s from yourself!”

Universities, which are always underfunded in compari­son with the projects they would like to undertake, cannot function without copious supplies of slave labor. These are called “graduate students.” I suppose I should be grateful, Babylon told himself, that at least Margaret gave me two extra pairs of hands—of course, I had to beg for them.

But the two graduate students were a big help all the same. Marco, the Filipino-Malay-American, had listened quietly to his instructions, nodded and gone off to arrange storage for the Polynesian material; Althea, the blond young woman from Texas, went to work instantly with a portable processor to read out the index codes from the glittering sphere and plan its storage in the databanks. She was quite a pretty young woman, and having her move about his office, with the faint wisp of perfume that seemed to follow her everywhere, reminded Babylon un­comfortably that it had been a long time since he and Sheryl had released their sexual tensions on each other. He punched out Sheryl’s code once more, got the same re­sponse, swore to himself … and, after a moment’s thought, replayed the message from Cuckoo.

His own face looked out from the stage at him, and his own voice spoke. A shiver ran up his spine as he heard himself say, “Hello, me. Is that how you say it? I mean, how I say it—or we say it?” Jen’s face grinned at the other Jen, unhappily. “Well, listen, we both know this is strange, and we both know everything either of us knew up until old Margaret talked us into this thing—so I’ll come right to the point. I know you’re busy. I know you don’t want to do this. But I need help. I have this body of material and I have to have total interpretation of it—semantic, morpho­logical, grammatical, every parameter there is. It’s a matter of life and death, Jen. Our life.”

The one and original Jen Babylon—the one on Earth— snapped it off at that point; the rest was technical instruc­tions, and they were already being carried out.

Since there was no help for it, Babylon was slowly begin­ning to come around to the feeling that this new task was going to be interesting in its own right. What made Baby­lon a professor in the first place was the pure lust of the scholar, and here was a whole new family of tongues, tachyon-transmitted from forty thousand light-years out in space, and all his. No ear on Earth had ever heard these sounds before, no eye ever seen the markings. He drew a pad toward him and began to make notes.

“Dr. Babylon?”

He looked up, irritated. “Yes, Althea?”

“I didn’t want to interrupt you, but you know I used to be pretty friendly with Sheryl, and I couldn’t help seeing that you were trying to call her.”

He nodded, and she went on.

“I think she’s there, really, Dr. Babylon. My boyfriend lives right down the block from her and he’s seen her, along with, uh, some of the—”

Babylon finished for her: “The Kooks.”

“Yes. The Kooks. They’ve got a sort of a pad, or a com­mune, or whatever they call it right in her apartment house. Right next door to hers, in fact.” She broke off to look at the display on her portable processor, punched a quick command, studied the result, and then looked up. “You know, Dr. Babylon,” she said, “it’s going to be at least a couple of hours before there’s anything for you to do here.”

He leaned back and rubbed his neck. “I suppose so,” he agreed.

“Well, I was just thinking—you’ll probably be working late once you get started. So if you wanted to take off for a few hours, Marco and I can certainly cope with inputting the data.”

The more Babylon thought about it, the more it seemed like a good idea. And then there was the question of Sheryl …

He was already in a hovercab, human-driven this time, across the Charles and heading for the old buildings behind the Criminal Courts when he realized just how tactful Al- thea had been. Quite a nice girl! She had put the idea in his head and then reminded him he could do something about it, all without appearing to interfere in his private affairs at all. A woman like that, he thought, would go far—

Which his taxi would not, it seemed. It had come to a complete halt. “Sorry, pal,” the cabbie said, leaning back toward the passenger section. “The damn Kooks again, wouldn’t you know it? They’re blocking the whole square.”

Babylon leaned forward to stare over the driver’s shoul­der. There were more of them than ever, thousands at least, as dirty and ragged and—exalted—as ever. They were chanting in such disorder that he could make out no words, but some of the placards they carried were read­able: don’t defile cuckoo! and criminals belong on earth, not in heaven! and a dozen others. The police were making no effort to disperse them, just to keep them from overflowing into the streets around the Criminal Courts Building.

Babylon glanced at his watch and made a decision. “Let me out here,” he told the driver. “I’ll walk the rest of the way.”

But, he thought, maybe what he sought was in that square …

In the detention-area halls of the Criminal Courts Build­ing Te’ehala Tupaia heard the noise from outside and dis­missed it. There were nearer problems. He followed the stooped Judas-ram of the file of Purchased People through one more barred door, and stopped short, eyes outraged by a flashing of cameras. Noise and confusion reigned here, too—fortunately, for no one noticed his lapse. He let his head fall forward and shambled docilely toward the prison­ers’ corral. Clearly they were in the news again, though he did not know why.

The court attendants managed to quiet the press and public long enough for the hearing to begin, but the noise outside continued to grow. Tupaia listened alertly, eyes looking up under lowered brows to try to follow what was going on. It was of no real interest, he decided, just more whiteskin foolishness, some legal point that required the presence of the Purchased People in the courtroom, but certainly nothing that would ever yield freedom to Te’ehala Tupaia of Polynesie-libre. He would have to get that by himself!

Because the Purchased People were either firmly con­trolled or apathetic, the courtroom authorities had not both­ered to handcuff them. Because Tupaia knew that his only hope of escape was to pretend the same apathy, he kept his muscles relaxed and his eyes downcast. But he missed nothing. That guard, just outside the rail, scowling at a photographer trying to get one last shot—surely that was a pistol in the holster at his belt? Those disheveled creatures by the door, reluctantly taking their seats as attendants whispered savagely at them—Kooks? They had to be; no normal human being, not even a whiteskin, would allow himself to appear in such wretchedly unkempt condition. And what was outside the door? It was a continuous rum­ble, like the combers crashing over the breakwater outside a lagoon, but he could almost hear words in it. More Kooks, no doubt …

He folded his hands placidly in his lap, while inside his skull his mind was racing with schemes. He let the court­room talk flow past him. Whiteskin justice! Whiteskin madness! Neither of them meant anything to Te’ehala Tu­paia.

There had been a time, of course, when he had not yet learned the bitter truths about whiteskin “fair play.” He remembered, with both nostalgia and rage, those long-ago, hot teenage years, working in the tourist hotels, always at a trot at the dinner hour to be sure M’sieur’s wine carafe reached Table 10 and to lug the huge, searing silver tureen of soup to the six American ladies at Table 45. A fifteen-year-old kid—could he be blamed? All he knew was that he wanted enough money to buy a Moped and, someday, rise in the whiteskin world until he, too, could be a rich tourist. Fantasy! It had all turned out to be lies and betrayals.

For a moment he let himself listen to the endless wran­gling drone from the front of the courtroom. Attorney for the defense was saying that his clients had paid good money, strictly according to Statute 53 U.S. 195, and they weren’t getting their money’s worth—”clients” meaning strange creatures from another world, and “money’s worth” meaning Tupaia and the other Purchased People them­selves! And the attorney for the prisoners was protesting that no one doubted that, all they had to do was abandon their plans to use these Purchased People on Cuckoo and destroy their tapes.

Whiteskin lunacy! How could grown human beings per­suade themselves that this meant anything, when it af­fected no one nearer than forty thousand light-years away, and at that distance was unenforceable anyway? He cared not at all whether the attorney for the prison system suc­cessfully defended their sale, or the Civil Liberties lawyers won their technical point. Let the judge decide what she would, it would mean nothing.

But the growing volume and frenzy of the noise outside the courtroom … they might mean something. They meant, at least, confusion and turmoil—and in some sud­den confusion was Tupaia’s only hope.

But the hope dwindled and, at last, died away. The judge impatiently cut the lawyers off, announced that she had heard the arguments and would give her decision in chambers at a later date.

And that was the end of it.

The bored attendants prodded the torpid Purchased Peo­ple toward the door, and Tupaia felt despair soak into his heart once more. Back to the detention cells again, with the strange screams and moans in the night and the queer, in­human things that looked out of his fellow prisoners’ eyes.

But perhaps not.

The guards were nervous, whispering to each other. As they approached the rear entrance where the prison vans waited to take them back to their cells, Tupaia heard the crowd noises from outside, closer and louder than ever. The guards stopped them at the door. Then two guards, side by side, thrust it open and shoved their way out into the milling, shouting mob.

Then it became easy.

The guards expected nothing threatening from their pris­oners; it was the Kooks they were worried about. Tupaia found himself directly behind the one who had stood guard nearest him in the courtroom. And the gun was still in the holster.

Tupaia stood up to his full height and reached forward, one great arm encircling the man’s neck. He snapped it as easily as he had long ago plucked hibiscus blossoms for the breakfast tables of the tourists. He let the man fall under the stampeding feet of the mob and turned, the gun swiftly concealed in his blouse. No one had noticed as Tupaia melted swiftly into the rioting crowd.

Long before then Jen Babylon had given up the useless scan of ecstatic faces in the Kook mob, pushed his way through, and hurried the few short blocks to Sheryl’s apart­ment building. The autodoorman passed him readily enough—his facial profile had been recorded long ago— and in moments he was hammering on the door to Sheryl’s apartment.

No one answered the door. Yet Babylon was sure he heard sounds from within. He could not identify them; not the voices of a party, or a show on the stereostage. Not any sounds he recognized, even with the sharpened ears of his profession. They were so faint that he was hardly con­vinced they were real, but they sounded like—like what?— like cards shuffling? or dice rattling?

“Sheryl!” he called. “It’s Jen Babylon!”

Still no answer. He shrugged and moved grimly down the hall. It was the only other apartment on the floor, far bigger than Sheryl’s little corner; if Althea’s information was right, perhaps the girl was inside. He banged on the door, bruising his knuckles.

The answer he got was not the one he might have ex­pected. The door to Sheryl’s own apartment opened down the hall, and she stood in the frame, peering toward him. “Yes, Jen?” she said softly.

He was back there at a bound, furious, brushing past her into the tiny room. “My God, Sheryl!” he cried. “Don’t you know I’ve been worried about you? What have you been doing?”

She followed him slowly inside, her face radiant. “The very greatest of things, Jen,” she told him solemnly. “You had no cause to worry.”

“No cause! With you mixed up with these maniacs! Starving yourself. Letting yourself go to pot—look at you!” he said bitterly, turning her to face a mirror. She had been thin; now she was almost ethereal, except that the smudged face, the careless hair, the shadows under her eyes were nothing that could be called ethereal. The whole apartment was as uncared-for as its owner. Furniture appeared to have been shoved out of the way, for what purpose Baby­lon could not guess; the place had not been dusted or swept in some time, and there was a sour, metallic reek that he could not identify.

“Please go away, Jen,” Sheryl said softly.

He shook his head, almost ready to admit defeat. What was he doing here, anyway? She had a right to do what she chose with her life— But on the other hand, what she was doing seemed insane, and didn’t he owe her at least an attempt to bring her back to her senses? “Do you know what you’re doing to yourself?” he demanded.

“Of course I do, Jen! I am redeeming myself—and all the rest of the sad, shamed human race, too! I Cry the majesty of Cuckoo. It is coming to save us all!”

“Oh, Sheryl,” he said, pitying and almost fearing her, as one pities and fears a lunatic. “Won’t you come with me and let me get you cleaned up, get some food into you, see if you need medical—” He broke off, listening. “What’s that?” He turned toward the closed closet door, and Sheryl gazed serenely with him.

“Don’t open it, please,” she said. It was as if she had asked him to pass the butter. He stared at her, suddenly angry.

“Sheryl! Don’t tell me! You can’t have another lover in the closet—that’s farce!”

“Please don’t open the door, Jen,” she insisted softly.

He stared at her, then at the door. There was a repeti­tion of the thin, rattling sound that had caught his atten­tion. It made up his mind for him.

“Be careful,” Sheryl begged as he whipped the door open, but he hardly heard her. The closet was a closet no longer; it led through the ragged remains of what had been its back wall to the apartment next door. Forgotten gar­ments were hanging on racks still, and he could not see past them; but he could hear, and there were a great many people in that other apartment. People—or something else.

For in the foreground was definitely “something else.” It was one of the unearthly crystal crustaceans, far huger at close range than they had seemed from the bridge over the Charles. Standing before it, Babylon could see that it was no terrestrial crab. Apart from the transparency of its body and limbs, its anatomy was only vaguely crablike. No eye- stalks, but two huge bulging orbs like a fly’s; no great crush­ing claws, but half a dozen slim pincers. Yet as it reared up to face him, the limbs clicking against the carapace, it looked surely menacing.

Babylon fell back a step. “What—what’s it doing here?”

Sheryl’s eyes shone with rapture. “It belongs here, Jen! I don’t want it harmed!”

“I won’t hurt the wretched thing,” he said, falling back as it moved slowly into the room—actually, he was far more worried about harm going in the other direction. “But you have to tell me what’s going on!”

“We are redeeming the Galaxy!” she cried proudly. “They’re servants of the Crystal Maid, and so am I!”

Babylon stared at her, incredulous. He shook his head. “You’re out of your mind,” he said. It was not a reproach. It was meant as a statement of fact—fact as Babylon per­ceived fact—the same conviction that a thousand others like Babylon had held over the millennia, as someone dear to them followed Sun Myung Moon or the Reverend James Jones, or joined the Hitler Youth or the Komsomol, or went singing off to the Crusades. “Anyway, this thing can’t be here,” he said firmly. “It’s dangerous. I’m going to call the police.”

He moved toward the stereostage, but the giant glassy creature was faster than he. It scuttled, with a quick, dry, tinkling sound, to put itself in the way.

“Oh, Jen, stop!” Sheryl cried.

But it was not Sheryl that stopped him. The creature rose up, bright, faceted eyes gleaming out of the crystal shell. The flutelike hissing of its breath formed into words. “Oh, Jen, stop,” it whispered, and then, “I won’t hurt the wretched thing.”


What a place! It had been terrifyingly alien in the first moments, baffling after a day, and now, as time passed and he saw more of its strangeness, it had become totally incomprehensible.

It was also huge—he was just beginning to discover how huge. Jen Babylon’s new home was an artifact, created in the first place from tachtran patterns assembling the ran­dom elemental particles that floated in space into a tiny orbiter, then gradually expanded by mass drawn from the surface of Cuckoo itself. He had not formed a good idea of its size, because there were parts of it where he was not welcome and parts where neither he nor any other human could penetrate—refrigerated sections, blazing-hot sections, sections filled with poisonous gases or even liquids, where the few representatives of wholly nonhuman galactic races lurked, appearing among the carbon/oxygen/water races only through Purchased People or robots. The few parts he had seen were dismaying enough, especially considering their occupants! The Scorpian robots, the T’Worlie, the Sirians that seemed to be a single immense floating eye, the horse-headed Canopans, the deltaforms—he had not yet managed to catalog them all in his mind, much less to know who they were or where they were from. Less still to know friend from foe.

And why, in so dispassionate a scientific enterprise as the exploration of Cuckoo, should there be friends and foes?

But there were; and Babylon felt himself plunging deeper each day into a kind of paranoia of his own. What saved him was his work. Even his feelings of personal loss and anger receded in the face of the most interesting chal­lenge his professional self had ever received.

The language of the ancient ship was opaque to every probe he could summon to his service. The big farlink computer munched the facts he poured into it, and re­turned only null results. The datastore he had sent to his other self in Boston had brought nothing in return—not even an acknowledgment. Doc Chimp chattered and joked and sympathized, but could not help; Ben Pertin appeared briefly and mysteriously, most often with dire warnings— “Say nothing to the Canopans!” “Be careful, there’s a Scorpian asking questions!”—and then disappeared on strange errands. His best and closest companion was the TWorlie, Mimmie. “Every language must have the same basic structure!” Babylon declared to the little butterfly- thing, getting a sweet carnation-and-maple-sugar scent of sympathy in response. “That’s fundamental to the concept of communication. The naming of objects, the description of action, the qualification of the ‘nouns’ and ‘verbs’ that they represent—how can you have a language without those things?”

“Agreement,” trilled the TWorlie. “Concur in state­ments. Conclusion drawn: We will succeed, Dr. Jen Baby­lon.”

“But when?” Babylon snarled, and the TWorlie fell si­lent. “There are shared assumptions in all languages, but there are also assumptions that are unique. Or anyway dif­ferent, and here’s an example right now. You don’t really understand why I’m frustrated and upset, do you?”

“Agreement,” the TWorlie signaled. “Statement: Our time horizon much longer than yours.”

“And therefore you’re more patient, right. Well, whoever built that ship has a history completely separate from yours or mine, otherwise we would have found congruences be­fore this. We’re wasting our time with Pmals. We need to go back to plotting frequencies, making assumptions, test­ing them out—like code-breaking. If we only had some na­tive languages to work with.”

The TWorlie chirped, “Statement. Native languages ex­ist. Qualification. Apparently limited to beings of galactic origin, circumstances of presence on Cuckoo not known.”

Babylon nodded; it was true that many of the galactic species seemed to have close relatives on Cuckoo. But then he changed the nod to a headshake. “But that’s not good enough; we need real autochthonous languages. If we had that, it would be straightforward. The techniques were es­tablished long ago, by a man on my own planet named Jean Francois Champollion. He worked with ancient Egyp­tian, an extinct language of which we had only written rec­ords. —What’s the matter?”

He had detected the scorching smell of disagreement. “Inability to concur in statement,” the TWorlie chirped mildly. “No language ‘extinct’ if population speaking or af­fected by it survives.”

“Well, right, that’s true enough. I didn’t mean it was wholly gone, but the only record we had was in convention­alized pictures. What happened in the long run was that this linguist found a stone—it’s called the Rosetta stone— on which the same message was carved in the unknown language and a known one. If we only had something like that, we might have some hope.”

“Estimate probability high that such or analogous break­through will occur, Jen Babylon.”

Babylon grinned and brushed his hair back. “Well, let’s get back to it.” He stared around the room. “We’ve made a mess of this place, haven’t we?” There was a litter of hard work in the chamber, half-dismantled Pmal translators, sound tapes and spheres, optical records in a dozen physi­cal forms, frequency analyzers, and all the other tools of their trade. “Well, let’s play the audio tapes again. If we can spot any phonemes that look like inflections maybe we can subtract them and get down to root words, at least— but I’d still like a Rosetta stone.”

“Dear friend,” piped a familiar chatter from the door, “perhaps this old monkey has brought you one—though you may not like the way it looks!”

It was Doc Chimp, of course, clutching a handhold with one long, skinny arm as he floated easily in the entrance. There was nothing easy about his expression, however. His head was cocked as though listening, and he darted glances back over his shoulder as he spoke. He said hurriedly, “He’s coming. He’s a little, uh, unusual, Dr. Babylon, but I think he may be able to help you. —Ah, here he is!” And he swung inside the entrance to give the next creature a wide berth. From safety at the side of the wall Doc Chimp piped nervously, “Allow me to introduce our guest, from the dis­tinguished, and possibly autochthonous, race of Watchers.”

The words were not necessary. The smell was introduc­tion enough. The TWorlie whistled feebly and fluttered over to the air vent, but Babylon had no such escape.

The creature that came slowly through the door, handing itself carefully from one holdfast to another, was as evil in appearance as anything Jen Babylon had ever imagined. Its top was black, its belly red, both fused out of shiny chitin armor. It had small leathery wings that looked useless but in fact were ample within the orbiter, or on Cuckoo itself. It had a parrot beak, with its ears queerly set beside it; the eyes were farther back on the head, like a squirrel’s. And it stank.

It squeaked peremptorily, and all of the working Pmals near Babylon translated its words: “I will assist you infe­rior races, but you must respond quickly. Now! What can you tell me of your problem?”

Babylon’s one previous glimpse of a Watcher, at the strangely inconclusive meeting he had been summoned to, had been so diluted by the presence of a dozen other strange creatures that the Watcher had been little more than one additional horror in a saturating sufficiency of them. All by itself, it was something special. It was one of the few Cuckoo creatures that did not seem to have some analog on one of the galactic planets—because it was na­tive? Or simply because its home planet had not been inte­grated into the galactic web? That was a good possibility! Who would want to include these things in any possible congeries of cultures?

“I instructed you to be quick!” the Watcher squealed dangerously, and Doc Chimp nervously cleared his throat “If you will, Dr. Babylon,” he pleaded. “I know our, uh, guest is somewhat, ah, disconcerting”—the Watcher squealed a disdainful laugh—”but his entire race maintains some sort of contact with the oldest, maybe vanished cul­tures on Cuckoo. The ones who built the other orbiters, maybe; maybe even the wrecked ship. And his language has not been entered in the databanks in any complete way, because of the, uh, lack of social accommodation—” “Be quiet, animal!” the Watcher commanded. “You other animals are investigating matters that concern me greatly. I will exchange information, but begin!”

From its position beside the air vent the TWorlie gasped: “Recommendation: comply. Alternative: termi­nate dialogue.”

Babylon nodded, and bent to the instruments. “Very well,” he said, searching for the datastores he needed—any help was worth having, at this stage! “These are the sound sections of our records from the ship, and they seem to be associated with certain visuals.” He slipped two of the hex­agons into the reader and started the playback, and at once the raucous noises he had heard under such terrifying cir­cumstances filled the chamber. The Watcher thrust itself across the chamber to remove itself as far as possible from the lesser breeds and settled down to watch and listen. The smell was nearly strangling Babylon, and something was buzzing annoyingly around his ear. He swatted irritably at it—a floating mote of silver, just hovering—and stung his hand. It was like slapping a sharp flint.

Doc Chimp cried, “Oh, Dr. Babylon, it’s a Boaty-Bit! Don’t hurt it!” He thrust himself toward the spinning fleck of diamond brightness, then sighed in relief. “Ah, there’s another”—as a quicksilver gleam darted toward its com­rade—”and it seems all right You don’t usually see them in ones and twos like this. The more they are the smarter they are, you see—collective intelligence. Ah, they’re flying off. I’m glad you didn’t damage it, Dr. Babylon. You don’t want the Boaty-Bits mad at you—oh, no!” The two little midges had drifted too close to the Watcher, who had flashed out a pink, slimy tentacle and whipped one of them into its mouth. The other darted away furiously, hesitated, then streaked out and down the corridor. “Cannibal!” Doc Chimp cried. “That’s an intelli­gent creature, Watcher!”

Astonishingly, the Watcher laughed, a raucous bark that was unmistakable regardless of language. He whistled a se­ries of short, sharp sounds, and the Pmal rendered it into English for Babylon:

“True I eat flying Bits and even Earth bipeds,” he said contemptuously. “Untrue to call it cannibalism. Not my species! But I give you assurance I will not eat anyone here in this room now.”

“Kind of you,” Babylon murmured, resisting the impulse to edge away. The Watcher laughed again.

“Spoken with humor. Good. We Watchers appreciate courage, even from lower forms such as yourself. Now maintain silence while I inform you. We Watchers are sub­ject to certain behavior constraints, acting on behalf of an­other species that you have never seen. I myself have never seen them, receiving instructions only at second remove. I now desire to complete study of your records, to shed light on matters concerning wrecked ship that do not concern you, therefore be silent while I listen.”

As time wore on the smell dwindled in Babylon’s nos­trils, though it never became tolerable. Still, he almost for­got it, for the Watcher almost at once reacted. “Stop!” he commanded. “Reverse! Play again— Yes, now stop there!” And he switched from the painful squeals to a deeper, rumbling sound very like the sounds from the hexagons themselves.

The Pmal hesitantly rendered his new language as, “Dis­play … graphics.”

And the whirling images on the visual track suddenly settled down and revealed a mottled red scene, evidently the surface of Cuckoo, with curious markings that called attention to two points on the chart. Doc Chimp squealed faintly. “That—that’s where the wrecked ship is!” he cried.

“And that other—I don’t know, except I recognize that mountain. They call it Knife-in-the-Sky.”

The Watcher commanded in his own language: “Be still, animal. It is where the ship should have been, of course.”

“Of course,” the chimpanzee said finally. “Listen, Dr. Babylon. I’d better go check, see if the Boaty-Bit that got away is all right. I’ll be back—”

“It is unimportant whether you will be back!” the Watcher howled. “Continue transcription!”

The creature was both loathsome and frightening, but with its aid the translation began to become possible. Not easy. But there were breakthroughs. Babylon forced him­self to endure the stink and revulsion for hours at a time, tending the Pmals while the Watcher slowly built up a store of congruences.

And of course the little Pmal translators that every being on the orbiter carried as a matter of course were no use. They were no more than compact library stores, with some learning circuits. They contained the roots and equiva­lences of all the known galactic tongues, and from them were able to construct dictionaries for any related lan­guage. For unrelated languages they were of no use at all, and so the first task for Babylon and the TWorlie had been to put together a much larger translator, inputting to the farlink computer. Like all Pmals, their translator con­tained a nucleus of semiliving cells. The basic design, like so much of the Galaxy’s technology, was T’Worlie, but an ancient Earth linguist named Paul M. A. Linebarger had predicted it, and so most humans gave it his initials. It was not enough. To the word-matching and grammar-building of the Pmal, Babylon had to apply his quantum-dynamics procedures, and the T’Worlie contributed his race’s own form of entropic analysis … and gradually, slowly, the vocabulary grew.

Grammar was another problem entirely. It was on the rock of grammar that the mechanical translators of early Earth languages had failed. The old grammarians tried to construct a logical grammar for the English language and fell victim to the golden-age myth. They thought there must once have been some language that was constructed from prime principles and had not yet been corrupted by the easy slippage of everyday speech (which was wrong in itself), and they thought that language was probably Latin, which was even more wrong. Latin is an inflected lan­guage. By the inflected form of the verb “to love” you can see who is the lover and who the loved, a sort of relation­ship that English conveys by the position of the words in the sentence; so there the grammarians failed.

They failed, even, in deciding just what a grammar was. The old-time conception of a grammar was as a sort of black box. You put thoughts into it, and it converted them into sentences, so that a grammar was defined as a device which could generate every possible grammatical sentence, but would not generate any nongrammatical ones. No use. The definition was circular, like defining “red paint” as that which paints things red. It also took no account of the differences in meaning of the word “grammar,” defining a deep structure indispensable to communication as well as the conventions of ordinary talk. But that latter grammar depended on who was using it. That grammar, really, was no more than a system of identification codes to let the hearer know that the speaker was upper-class-educated, working-class-tough, urban black, whatever. One of the great triumphs of quantum-dynamic linguistics was that it cut through the semantic maze and struck right to the heart of meaning.

But not easily.

Not with pleasure, either, as long as the Watcher contin­ued to show up at regular intervals to listen for analogs and input his own language. Babylon and the T-Worlie worked out a bargain—they would take turns in milking the crea­ture’s knowledge—and when it was the TWorlie’s turn Babylon explored the orbiter. He did it mostly by himself; Doc Chimp had been staying away, and when the little chimpanzee’s absence had continued for several days Baby­lon sought him out.

He found Doc Chimp huddled over a stereostage, whis­pering to someone whose identity Babylon could not deter­mine. When he glanced up at his visitor the chimp’s ex­pression was almost triumphant, but darkened instantly. “Oh, Dr. Babylon,” he chattered. “How nice of you to visit this old monkey. If only you’d given me a little warning, though!” He seemed to be talking as much to the stereo as to Babylon.

“I’m sorry to interrupt you,” Babylon offered.

“No, no! Of course not! Just let me say good-bye to my friend here—” Babylon stayed near the doorway, politely out of range, while the chimp whispered a few more words. Babylon had never before been in Doc Chimp’s quarters. As a senior inhabitant of the orbiter, Doc Chimp had squatter’s rights on the cubicle he preferred, and he had decorated it to suit—a semiliving T’Worlie painting moved slowly on one wall, a stereophoto of the Serengeti plain occupied another. One end of the chamber was filled with a steel-pipe jungle gym, a children’s playground thing that seemed to be the chimpanzee’s sleeping place, since some of the pipes were hung with scraps of cloth to make a nest. “It’s not much,” Doc Chimp apologized, “but it’s my home, and welcome to it.” He sprang to find a drinking bulb and a few pieces of synthetic food. “At least have some coffee, please? Heaven knows it’s no good—there’s no good food on this whole orbiter.”

“I didn’t mean to interfere with what you were doing.”

The chimpanzee was silent for a moment, scratching at his leathery cheek with one long, skinny finger. “Can you stay here for about an hour?” he demanded suddenly.

“Why—I suppose so, but what for?”

“I want you to meet somebody.”

“The last time you brought somebody to meet me,” Babylon said, “he secared me half to death. Not to mention how he smelled.”

Doc Chimp grinned. “But you have to admit he helped you, right? Well, this time it will be different—although I think you’ll find there will be some help, too. They’ll be here in a little while, but please don’t ask any questions— you never know who might be listening!”

Babylon squeezed a mouthful oi the tepid imitation cof­fee past his lips, shuddered, swallowed, and said mourn­fully, “Are we ever going to get to the point where every­thing isn’t a mystery?”

“Not on Cuckoo, I’m afraid. Everything’s a mystery— not least of all, what we are doing here!” He pressed some levers on the stereostage and nodded to Babylon to come to look over his shoulder. “There it is,” he said, as a holo­graphic virtual image formed in the stage. “Cuckoo. Three hundred million kilometers in diameter and made out of—what? Space? It has so little mass there’s nothing we know of that can account for it. See the markings in bright relief? That’s what we’ve mapped so far. And the dark ones? Those are what we’ve actually explored.” He heeled a bar moodily, and the great simulated sphere began to spin until it was almost a blur. “That’s what we’ve got to show for more than a dozen years and a lot—oh, yes, Dr. Babylon, a lot—of lives. And no system, really. Every race wanted a priority given to its own analogs here on Cuckoo. And, my goodness, Dr. Babylon, we don’t have unlimited resources! So we wasted fifteen hundred launches, lost more than a dozen landers, killed off better than a thou­sand creatures, one way or another, just to peek at the least interesting parts. It’s all politics, you know. And we ter­restrial primates, like you and me, we don’t have as much muscle as some of the older, more powerful races. When the T’Worlie want something they get it! Same with the Sheliaks. One of the Sheliaks took a whole expedition down to that jungle there—you can only see it as a blur, but it’s a thousand miles across! He was studying thermosynthesis— the way Cuckoo’s life feeds on the heat flow from below, like some submarine colonies do in our own oceans back home on Earth, instead of light from the Sun. An interest­ing study, right? I thought so. That’s why I went along … And when the Sheliak probed too hard and started a volcanic eruption, I was one of the ones that died!”

“I’m sorry,” Babylon muttered. It was a foolish thing to say—how do you condole a person for his own death, when he is alive and well before you?

The chimp nodded moodily. “They’re all alike, Dr. Babylon,” he sighed. “Crazy theories. The Boaty-Bits and the Scorpians and the Canopans, they all think that Cuckoo might be made of some other kind of matter, with zero mass. Well, that’s moonshine! I’ve been there! So have you! It’s solid rock and soil and plants and lakes and oceans.”

“Of course it is,” Babylon said soothingly.

But of course it wasn’t. He recalled enough undergradu­ate science to be certain of that. No solid body of any such size could possibly exist. Or even a thousandth this size. The gravitation of its own enormous mass would squeeze it down into a black hole with no size at all, squeeze it finally out of the physical universe.


What was it? How had it come to be, and what strange new science could explain it? What sort of beings had lived on or around it? Maybe still lived? What had those orbital forts been built to defend? What had brought down the one they had entered?

Again he grappled with those perplexities, and again he saw no answers.

The chimp scratched his leathery cheek. “The Boaty- Bits you can understand, a little,” he said. “They’re so dif­ferent, being a collective entity and all—they don’t have the same feelings as individual organisms like the rest of us. They think we individuals are almost like amputees— they’re sorry for us, would you believe it? But the Sirians! They have no real sense of time—if it won’t happen in the next week they couldn’t care less, and that makes them dangerous …” He paused. “What’s the matter, Dr. Baby­lon? You’re giving me a funny look.”

“I’m wondering,” Babylon said, “why you’re telling me all this right now. I get the feeling you’re just making con­versation to keep me here.”

Surprisingly, the chimp grinned. “Right you are, Dr. Babylon,” he agreed. “And I guess it worked, because the people I want you to meet are here now. Come in, folks! Let me present, direct from Earth, the Galaxy’s foremost expert in quantum-dynamic linguistics and heaven knows what else, Dr. Jen Babylon!”

The pair that gently launched themselves into Doc Chimp’s chamber were almost more surprising than any of the monsters Babylon had seen. Human, yes, undoubtedly. But what humans! They were a man and a woman, each more than two meters tall, and slimmer than human beings had any right to be. “This is Org Rider, Dr. Babylon,” the chimp said proudly. “He’s a real person, not a tachyon dupe like the rest of us.” He didn’t look real to Babylon, he looked grotesquely stretched—like a normal man of a hundred and seventy-five centimeters or so who has been pulled thin, like taffy. He wore a cache-sex, a belt with pockets and loops, a few straps of harness, and nothing else. “Of course,” Doc Chimp went on meditatively, ” ‘real’ is a kind of comparative word, isn’t it? I mean, Org Rider isn’t ‘real’ Earth primate in the sense that you and I are, or anyway used to be—he doesn’t come from Earth. He comes from here. And this is his good lady, Zara, who I think you may have met before.”

Babylon was staring. “Zara Gentry!” he exclaimed.

The wraith-thin woman laughed—a solid, human laugh, regardless of her appearance. “As good a name as any,” she acknowledged.

“No, no. I mean I’ve met you before. You’re a famous newscaster, back on Earth, Mrs. Gentry.”

“Just Zara, please. I was born Zara Doy, then I married and I was Zara Doy Gentry—I understand that on Sun One I’m Zara something else—but here my husband and I don’t share the same name. He is Org Rider. I am simply Zara—an edited version of myself,” she added wistfully, “but still the same person.”

Babylon said humbly, “I really don’t know very much about what an ‘edited’ version of a person is—in spite of the fact that it happened to me, and I’m reminded of it every time I wake up and reach for the glasses I don’t have anymore.”

Doc Chimp laughed. “Let me tell him, Zara,” he volun­teered. “Dr. Babylon hasn’t been here long enough to learn all our little ways. But it’s simple enough. When you’re tachyon-transmitted, you know, all that really gets sent is a sort of blueprint of what you are. Then it gets put together at the other end, out of whatever odds and ends of matter happen to be about; and you can always edit the blueprint Change it, you see? Adapt the pattern to special needs. Suppose you want to live on a water world; well, it’s easy enough to modify your blueprints to let you breathe water. It takes gills, o’ course, and some changes in your metabo­lism, but that’s easy enough. Lots of the folks you see around the orbiter are edited copies—chlorine-breathers, changed to an oxygen atmosphere. Light-gravity people— well, you don’t see them changed much here, because it isn’t necessary, but there are plenty of them rebuilt for heavy duty, as you might say, back on Earth. So, in order to make Zara less conspicuous when she was first sent down to Cuckoo, minglin’ with the aborigines, as you might say, she was just stretched out a little.”

Babylon listened thoughtfully, but his mind was work­ing. “Doc,” he said at last, “you’re an absolute gold mine of information today, but I still get the idea that you’re talking to keep me from asking questions.”

Zara answered for him. “It’s true, Jen,” she said. “There’s something we don’t want to talk about yet, and it’s true that we came here just to see you.”

“All right, so when are you going to stop being mysteri­ous?”

She laughed. Her dimples were just as attractive on a face stretched thirty percent beyond its norm as they would have been on the original, Babylon decided. “As to what we don’t want to talk about, that will have to wait a day or two. As to what we came here for—tell him, Org Rider.”

“Very well, I will tell it,” said the man with her, pulling a small glittering sphere from one of his belt pockets. “This is for you, Jen. It does not directly relate to your linguis­tics, but it will, I think, be of interest. It is the record of certain investigations Zara and I made.” He tossed the sphere to Doc Chimp, who retrieved it nimbly from the air and fitted it into his stereostage. “Display the first view,”

Org Rider ordered, and obediently a landscape filled the stage, dominated by an immense, distant mountain. Org Ri­der said, “That is my home. That is Knife-in-the-Sky, as it is seen from my tribe’s mountain. My ancestors have lived there for as long as the oldest singer can say. But when Zara comes, and I see her, I ask questions. Why are we so alike? Are my people once from that little planet where she comes from? How can I find out these things. So I ask Zara, and she tells me, ‘paleontology.’ And I ask her, how can we get ‘paleontology’?”

Zara grinned. “I explained what it meant—digging down for fossils and so on—and we imported texts and manuals from Earth and made ourselves paleontologists. We started digging. Our work is very sloppy by Earth standards, of course. But it’s also a lot easier. We don’t have to mark geologic formations with precision, because there haven’t been any big faults or earth shifts. Just a gradual deposi­tion of silt and sand and clay from the rivers that run off Knife-in-the-Sky. The dating was hard—well, I’ll be honest. It was impossible. We tried radio-carbon dating ourselves, working out of a textbook—forget it! For one thing, there were too many unknowns that might contribute radioactiv­ity from the Cuckoo atmosphere, but the worst part was we just didn’t know what we were doing. But then we were lucky.”

She hesitated, and glanced at her husband. “I guess we were lucky,” she amended. “What I mean is we got some help from the Sirians. They were interested too, because there are analogs of Sirians on Cuckoo as well, just as of the Boaty-Bits and the Sheliaks and lots of others. Most of them don’t seem to care. The Sirians care. They are a very vain, proud race, and working with them was no pleasure. Have you ever seen a Sirian? Looks just like a large, float­ing eye? Almost all soft tissue, nothing to leave fossils? Yes. Well, that’s why they came to us for help. They’re very good at potassium-argon dating; they can pinpoint the argon-isotope balance to within almost a century or so, and that goes back much farther than the carbon procedures. And so we dug. Show him, Org Rider,” she said to her husband, who nodded and punched out commands on the stereostage. A virtual image of the skeleton of a hand ap­peared. “This is the earliest we found, Dr. Babylon. Thir­teen thousand years ago, according to the Sirians. And as soon as they got that dated they suddenly lost interest, wouldn’t even talk to us anymore.”

Babylon studied the virtual image uncomprehendingly. “Do you see how short the fingers are?” Org Rider de­manded.

Babylon shrugged. “I wouldn’t call them short. They look about the same length as your own—much longer than mine.”

Org Rider flexed his long, supple hand, laughing. “I see you are no anatomist either, Jen Babylon. I had to learn this, too. See here. You think your fingers are only the part that extends beyond your palm and hand, because that is what you see. But that is not all. Rub your fingers across the back of your hand—do you see? Those bones you feel, those are the hidden parts of your fingers. They go all the way to the wrist.”

Babylon did as instructed, then stared at the stereo im­age. “Why, those are just the same as mine! Not stretched out of all reason like— oh, excuse me!”

Org Rider shook his head, smiling. “We are not Sirians or Sheliaks, Jen Babylon, so we do not take offense lightly. You are correct. The fingers are in exactly the same pro­portion as your own. Exactly the proportion of an Earth human now, or of the Earth humans who were alive there at the date given by the argon isotopes, which is perhaps thirteen thousand four hundred years ago. Those are the earliest we found. We dug further. But below that— nothing.”

When Jen Babylon told Mimmie about the results of Org Rider’s digging, the TWorlie exuded a cinnamon-bun odor of understanding. “Concurrence,” it peeped. “Statement: Similar findings for other Cuckoo analogs of galactic races. Conclusion: Event of thirteen thousand four hundred years ago brought them here simultaneously. Query: Nature of event?”

Babylon rose and stretched, catching at a handhold to keep from drifting away from the instruments. “Yes, that’s the question, isn’t it?” he replied. “Something happened here, all those years ago. Before that the only life was na­tive—whatever that was. After it, there were immigrants from almost all the galactic planets. But how? I guarantee the Cro-Magnons didn’t have the tachyon-transmission links on Earth—I don’t know how it was with you T’Wor- lie.”

Over the time they had been working together Babylon had discovered that the TWorlie had a sense of humor— hard to pin down, with the dehumanizing effect of transla­tion through the Pmals, but popping out at unexpected times; they had become accustomed to exchanging pleasan­tries. But Babylon had forgotten the third being present. The Watcher hissed in rage, and the Pmal struggled with its furious squeals with only partial success: “—blas­phemous—offensive little animals! What you deserve—” The Pmal could not manage to say what they deserved, and it was no doubt as well. The Watcher’s slimy pink tentacles were quivering with fury and, abruptly, it turned and hurled itself out of the chamber.

Babylon gazed after it in dismay. “What did I say?” he demanded.

The TWorlie said hesitantly, “Statement: Watchers are deputies of some older, perhaps extinct race. Conjecture: Attempts to discover identity of same may be offensive, especially when levity is involved.”

Babylon found he was shaking. “Well,” he said at last, “we’ve pretty nearly pumped it dry anyway—and I admit I was getting tired of the way it smelled. Tell you the truth, Mimmie, I kind of hope it never comes back.”

And for several days he got his wish; the Watcher re­mained absent, while the two of them worked at correlating the data it had provided. It was not particularly difficult work, since by now the Pmals had the sketchy beginnings of a vocabulary to work with, and at least some tentative grammatical models. There was still no word from that other Jen Babylon on Earth, but the farlink computer put a great deal of power behind their processing, and it be­came clear that what they had rescued from the wrecked ship was of immense value. Item: a detailed map of the surface of Cuckoo, so huge that it could be presented only in segments a thousand miles square—there were more than a million of them! Item: On the segmented maps, symbols that indicated places of special interest—what the interest was, was still unclear, but one of them had been the location of the wrecked ship itself. Item: What ap­peared to be operating manuals for the ship’s equipment: weaponry (but none of the weapons were available to test); drive controls (but the ship itself would never move again); communications. And, of course, every datum was a fresh puzzle, not made easier by the accumulating debt each of them was beginning to owe to fatigue. Babylon passed his hand across his eyes. “The wrecked ship is marked,” he muttered, more to himself than to the T’Worlie. “See those radiating lines? And the same pat­tern shows up five—no, seven more times on the globe.” He peered blearily at the stereo image and nodded. “Yes,’ he said, “the globe is divided into octants, and there’s one of those special marks in each one. What do you suppose it means? A sort of local capital for each section? A military headquarters? Some particularly important spot—that maybe the wrecked ship was attacking?”

There was no answer from the TWorlie, except an unfa­miliar burning odor. “And these symbols in the communi­cations data,” he went on. “farlink gives us a match— they represent the concept ‘zero-mass tachyon.’ But what’s a zero-mass tachyon when it’s home?”

The TWorlie was silent for a moment before it replied, while the scorching odor grew. Babylon turned uneasily to face it. “Statement,” it said faintly. “Tachyon is defined as particle that obeys law of velocity of light as limit, but in its case as lower limit. Statement: Photon is defined as par­ticle that has rest mass of zero. Conjecture by analogy: ‘Zero-mass tachyon’ may be particle that has infinite speed. Further conjecture . .

But the peeping voice faded away, and the Pmal fell silent. “Oh, hell,” cried Babylon, suddenly aware of the bedraggled filmy wings, the dullness in the five clustered eyes. “You’re bloody exhausted, aren’t you? I’ve been driv­ing you too hard!”

TTie TWorlie managed a faint chirp, which the Pmal rendered as, “Concurrence.”

Babylon shook his head in self-reproach. The TWorlie were almost the most ancient of the civilized galactic races, with a time sense that extended centuries into the future … and an unhurried, placid way of life to match. “I’m sorry,” Babylon said. “You need rest! We both do, I guess, and it’s my fault.” He pushed himself away from the pro­cessors and gazed around the room. “We’ve made a lot of progress, anyway,” he said. “We’re entitled to a break. Take the day off, Mimmie—I mean, please,” he added hastily, conscious that he was giving orders to one of the race that had essentially founded the galactic culture. “I will, too. Then when we get back maybe we can figure out just what to do with all this stuff . .

The butterfly wings trembled, and gently eased the crea­ture toward the exit. It managed a faint, “Thank you,” and was gone.

Babylon did not at once follow his own instructions. He hung relaxing from one of the straps that festooned the wall—for him alone, really, because the TWorlie cer­tainly had no need of them. With the Watcher’s help they had achieved a great deal, but not without cost. The bill was coming due. Babylon was suddenly aware of his own fatigue and, worse, his general tackiness. His beard bris­tled, his hair was unkempt. He had not troubled to bathe in—how long? Several days at least, and he was abruptly conscious of the fact that he showed it in unpeasant ways—

Wrong. The smell that assailed his nostrils was not his own. He spun quickly to confront the doorway, and his suspicion was right

The Watcher hung there silently, staring at him with one immense, faceted eye.

What a revolting creature it was! Babylon repressed a shudder of distaste, but managed to say civilly, “Nice to see you again.”

The Watcher squealed contemptuously, “That is a lie! You are not pleased to see me, and I could never be pleased to see you.”

Babylon nodded, angry at himself for attempting cour­tesy with this incarnate evil. “Then why are you here?” he demanded.

“Because of urgency,” it squealed, “Our interests coin­cide for one short step more. Come!” And it flapped its leathery wings toward him, and the hideous pink tentacles caught him by arm and torso and dragged him away.

Jen Babylon was of average strength, but in those whip­like pink tentacles he was helpless. He was carried through the orbiter’s passages faster than he had ever traveled them before, as the Watcher’s powerful wings beat waves of its foul stench back at him. Dizzy from the kaleidoscope pas­sage of the chambers and corridors and halls, retching from the stink, exhausted from struggling against the py­thon grip of the tentacles, Babylon was half dazed when at last the Watcher thrust him free. He catapulted through a door, and was caught by the quick long arm of Doc Chimp. “Why, Dr. Babylon! I asked the Watcher to bring you here, but I never expected it to be this way!”

Babylon shook himself free, clutching at a wall fixture. “It doesn’t matter,” he said, looking about. The chimpanzee was not alone in his chamber; the two stretched-out human beings he had met before were there, Org Rider and Zara; so was Ben Pertin—some Ben Pertin or another. And so was a stranger.

Zara pushed herself close to him, her face concerned. “You look like you’ve had a hard time, Jen. I’m sorry. I asked the Watcher to be gentle, but it’s not in his nature.” She turned and squealed commandingly at the Watcher— not bothering to use the Pmal, Babylon observed with won­der. The Watcher made a contemptuous sound in return, hovering solidly just outside the door. “He’ll stay out there, Jen,” Zara said. “Since he’s a Watcher, we’ll let him watch for us—and the air’s better in here that way. There are beings on the orbiter we don’t want to come in here just now. I promised you that we’d stop acting mysterious as soon as we could—and now we can.” She nodded toward the stranger in the room. “Jen Babylon, I want you to meet Redlaw, the human being who knows more about Cuckoo than anyone else.”

If Org Rider and Zara were tall, this man was a giant. He overtopped them both by inches, and where their frames were stretched and slim his was solid. “Hello, Jen Babylon,” he boomed, bright green eyes staring at Baby­lon’s. “I hear you’re the one I have to thank.”

“For what?” Babylon asked, and it was Zara who re­plied:

“You gave us a key we’ve been looking for for a long time, Jen. When the Watcher helped you interpret the graphics Doc Chimp realized at once what it meant. One set of coordinates for where the wrecked ship hit the ground. Another for where it was supposed to be going—its home base, in other words. And he came at once to Org Rider and me, and we got word to Redlaw, on the surface of Cuckoo, not too far away—and so he went there.”

The giant nodded. His hair was red and so was his beard, and his voice was deeper than any human’s Babylon had ever heard. “And I found something important,” he said.

Babylon cast a quick look at the Watcher. “Wait a min­ute,” he said. “If there’s anything secret—”

“It’s all right, Jen,” Zara reassured him. “The Watchers aren’t friends, not by any stretch of the imagination. But they’ve got problems of their own. They’re called Watchers because they are supposed to serve as scouts and guardians for someone else—probably the people who built the wrecked ship and the base. They haven’t been able to com­municate with them for a long time. They want to know how to get back in touch. It’s a religious matter to them”— from the doorway the Watcher squealed warningly, but she paid no attention—”or at least it’s a sort of built-in impera­tive. So we made a deal to exchange this information. As soon as we’re finished the deal ends—but for now, Redlaw, go ahead. Tell what you found.”

Redlaw nodded to Doc Chimp, who produced another of the bright dataspheres and inserted it into his scanner. “Here’s where I went,” he said, as a scene of a pretty lake with what looked like some kind of temple at its narrowest end appeared on the stage. “It’s got a special marking on the chart you showed Doc Chimp—do you remember?”

“I don’t think so,” Babylon began, and then suddenly, “Yes! Of course! It’s one of those special points in each octant of the surface of Cuckoo—like the place where the wrecked ship is lying!”

“Exactly. So I naturally thought it would have something to do with spaceships. The orbiters, of course; maybe a re­pair and maintenance base of some sort for them. But, as you can see, there’s nothing like that visible.” He stroked his long, lean chin, and rumbled, “That building had never been observed before. Not surprising, you know—there’s just too much of Cuckoo! But it’s not even in a common style. Certainly Org Rider’s people never worked in stone. The other races all have their own styles of construction, and none of them is like this … So I went inside.”

He gestured again to Doc Chimp. The scene disappeared in a cloud of golden flakes, then solidified to show the interior of a great pillared chamber. Overhead was a vaulted dome; by bending and peering up into the three- dimensional image Babylon could see that the dome was ornamented with a representation of a galaxy, lenslike, whirlpool-lined, made of a myriad of tiny points of light. “I don’t know how long it has been since this place was used last,” Redlaw said, “but there was still power to light that display—and for other things.” He stepped over to Doc Chimp’s side and manipulated the display; the holographic image revolved slowly, and they were looking out through the great pillars. “See that road?” he demanded, as a white, trenched avenue appeared. “It goes down directly into the lake. I have a theory about that. I think it goes down a long way under the water—why I don’t know. Maybe it was something like a launchway for water craft? I don’t think so. I think it was all exposed at one time, going down into that hollow to something else—something I couldn’t see, much less get to, under the water. And over the years, when it was untended and forgotten, rain or springs filled it and made the lake. Now look insidel” He rotated the image again, and Babylon gasped.

There was a statue at the end of the chamber, in hard white metal, the figure of a three-eyed biped. Though the flat head seemed utterly alien, the torso gave an impression of femininity. Its delicate arms were lifted. One three- fingered hand held a ball, the other a handled ring. There was something Babylon took to be a blouselike garment, portrayed perhaps as blowing in the breeze; but as Redlaw increased the magnification he saw that the unknown artist had portrayed wings.

From the doorway there was a sharp, hurting squeal which the Pmals could not translate. The Watcher was quivering with excitement, its pink tentacles crawling long­ingly.

Redlaw glanced at the creature, then lowered his voice to Jen Babylon. “I think those are the things he used to work for—wherever they are now. But they’ve left some­thing behind. Defenses—all around that little valley are the same crystal towers you found near the wrecked ship; it took them a while to react, but as I was leaving they nearly finished me. And what they were defending was in that chamber. Records—the same kind of six-sided rod you found in the ship; I brought a batch of them back for you, Jen. I had no way of playing them, of course. Weapons— perhaps like the ones that were in the ship. Perhaps some­thing different. I left them there. And—one other thing.”

He pulled out what looked as much like a collapsed hot- water bottle as anything Babylon had ever seen. It was open at one end, and possessed a structure of coppery, feathery metal tendrils at the other. “I didn’t know what it was either, Jen,” Redlaw boomed, grinning through his scarlet beard. “So—I put it on.”

Babylon accepted it and turned it over in his hands. It was lighter than he had expected—less massy, he corrected himself, since everything was “light” in the orbiter. It was even more flexible than it had appeared while Redlaw still held it; he could twist it, turn it, fold it; he could even imagine himself doing as Redlaw had, and drawing it on over his head.

But there was ancient power in the device; he could feel it. He temporized. “What is it?”

Zara answered for him. “Do you know what Purchased People are, Jen?”

“Sure. Everybody does. They’re criminals who have been sold to aliens to use,” he said impatiently.

“Yes, exactly. But do you know how the aliens use them?”

“Why, yes, I suppose so—I mean,” he said, floundering, “of course the technical details are a little out of my field—”

Zara laughed, nodding in friendly sympathy. “Mine too, Jen. Almost everybody’s. All we know, really, is that the Purchased People are given some sort of implant, which then puts them in direct communication with their owners. The owners can feel with their senses, see with their eyes, control their actions. Of course, some sort of tachyon com­munication must be involved, but that’s about all any of us knew. But this helmet—” She looked at it almost with awe. “It lets us listen in, Jen! It lets us experience whatever any Purchased Person in range is experiencing—and that means anyone on or near Cuckoo! And that means—”

Her husband interrupted harshly. “It means that for the first time we can find out what’s really going on here! Why some of the races are determined to destroy the re­search project, if not Cuckoo itself. Put it on, Babylon!”

He flexed it in his hands, still hesitating, and glanced at the doorway. He was startled to see that it was vacant.

“He’s gone, Jen,” Zara said, nodding. “This part of what we found doesn’t interest the Watchers; I think our truce with them is over.” She came closer and touched his arm reassuringly. “But our part is just beginning, Jen. Put it on!”


Te’ehala Tupaia, paramount king-warrior in the forces of Free Polynesia, shuffled along the line of prisoners. Muscles flaccid, he commanded himself. Eyes down! Fol­low the little old man ahead! Two steps, stop. Wait. Two steps more, stop again. It was not easy to remain impassive, since he was almost surely the only one in the line of Pur­chased People who both knew where they were going and had the freedom to protest or resist … if he dared.

But he did not dare.

The man ahead lurched and moved, and Tupaia sham­bled another two steps. Tachyon transfer! Even to a king- warrior, it was frightening. Because he was neither igno­rant nor actively possessed, he had plenty of time to consider what it meant. Tupaia was no ignorant beachboy. He had completed every grade in the mission school, and gone on to the university on Bora Bora—though all that taught you was how to be a tour guide or, at the upper stretch of ambition, a headwaiter. Even nineteen-year-old Tupaia had something better in mind than that.

But—this was not it! Even in Bora Bora they had heard of the tachyon transmissions, and the young men and wah- ines had debated wonderingly why anyone would venture such a senseless trip. Now Tupaia faced the questions as imminent realities. The first question in his mind was, did he have reason to fear this adventure? The second, was there anything he could do about it, anyway?

The answer to the first question turned out not to mat­ter, because the answer to the second was obviously no. When he took the next two steps forward, he was suddenly alone. The little man ahead of him had been manhandled through a sliding metal door, and disappeared.

And then it was Te’ehala Tupaia’s turn. The two bored guards kicked the door open and grabbed an arm each to hurl him in.

For a moment he stiffened in involuntary resistance. The guards felt it. One of them glanced at him with the beginnings of surprise; but he had the wit to keep his eyes cast down. He willed his muscles to relax, though he was twice the size of these effeminate whiteskins, and they hus­tled him in in his turn.

The door slid latched behind him. There was a bright blue flash, a sting of electrical spark, and a sudden sense of disorientation. And the door on the other side of the tiny chamber opened and, willing himself not to make that deadly blunder again, Tupaia allowed himself to slump for­ward to take his place once more in the line …

But there was no line.

There was no great, busy tachyon-transmission hall, with its high ceiling and tessellated floor.

There was not even a floor! Or, at least, no floor that came up solidly to meet his feet as a floor should do. He spun weightlessly across an eerily lighted chamber, until a queer doughy creature caught him roughly and thrust him spinning against a wall.

He had been transmitted.

He was somewhere else. On another planet. Or in a spacecraft, or on an orbiting satellite—wherever he was, it was not on Earth, or on any planet with enough mass to give a man solid weight.

How far away from home, he did not know.

And how much time had elapsed—how long his coded pattern had been held on file before a need arose that it could fill—and how many Te’ehala Tupaias had lurched out into the shattering realization that they had been thrust millions of millions of kilometers away, he did not even think to ask.

Although Te’ehala Tupaia had known of the existence of the great galactic races all his life, and had even seen a few specimens at a distance, he had never before been in such intimate proximity to one. Had never touched them—hot metal; soggy flesh the texture of clay; damp scales—and above all had never smelled them. They reeked! Tupaia was not particularly sensitive in such matters. He had grown up with stinks of rotting palms and washed-ashore dead fish, not to mention the middens and spoil heaps around his village. But the strong Pacific breezes carried the worst away, and even the worst was nothing like this stinging metal odor of the Scorpian robot or the sour decay of the Sheliaks.

At first his new captors seemed, peculiarly, almost as confused by him as he was by them. They hustled him through long corridors to a hot, huge metal space the size of a ballroom, filled with what seemed to be half-destroyed old machines. The Sheliak, the clay-fleshed creature with the astonishing ability to shape its body to suit its needs, extended one pseudopod to hang a Pmal translator around Tupaia’s neck. It spoke sharply, something that the transla­tor rendered as a cackle of gibberish.

“I do not understand you,” said Tupaia, shaking his head. The Sheliak recoiled in astonishment. There was a quick exchange between the aliens, drumroll from the Scorpian, tweeterings and whistles and growls from the oth­ers. The Pmal again produced only an unintelligible barn­yard cackle.

Then the Sheliak realized what was wrong. It reached out and made an adjustment to the device, gesturing to Tu­paia to speak. “My name,” Tupaia said, comprehending, “is Te’ehala Tupaia, paramount king-warrior of the forces of Free Polynesia, and I have been abducted and held cap­tive here against my will.”

That was enough. The Pmal identified Tupaia’s lan­guage from its store and corrected its programing. When the aliens responded, it at once produced their meaning in Tupaia’s own vocabulary. The responses were an agitated hissing and a high, tenor snare-drum rattle; and the Pmal translated them as laughter.

At least here there was no more need to pretend to be possessed by his alien purchaser. That was the most ob­vious improvement in Tupaia’s situation … maybe, he thought grimly, the only one.

Te’ehala Tupaia was resourceful and quick—he’d had to be, to avoid the colonial jails as long as he had. Within an hour of emerging from the tachyon chamber he had fig­ured out where he was—more or less—and even what he was doing there. It wasn’t hard to deduce that.- Obviously these creatures had summoned him up in order to do some­thing they couldn’t, or didn’t want to, do for themselves. That was what Purchased People were for. It had been a surprise to them to learn that he did not understand the language of his whilom owner, and to deduce from that that he was inexplicably free—or not free physically, of course, because they made clear he was not that, but free at least of the unwelcome alien presence that once had filled his mind. They asked questions about that, but not with much real interest, and when he could give them no clear explanation they did not press the matter. It didn’t interest them, really. What they wanted was the use of his physical body. Who was in control of it mattered very little.

Tupaia had not bothered to lie on that subject. He knew no more than they. There had been an hour of dreadful pain, the raw torture of senses he didn’t have, in limbs and organs he did not possess. It was obvious that something frightful had happened to his distant, alien owner. No doubt it had died. At least the pain had stopped, and where that inner tyrant had occupied his mind there was suddenly a blessed emptiness; Te’ehala Tupaia was himself again.

And would be free, too, as soon as he had disposed of this new crew of tormentors! Of achieving that he was quite confident. Physically the creatures looked formidable, particularly the hissing metal robot and the thing that looked like a gross, hovering blue eye, crackling with electrical forces, that they called a Sirian. But physical odds he could overcome.

What then?

Even Te’ehala Tupaia was forced to admit to himself that the way was unclear before him. He would have to wait and be ready for whatever opportunity presented it­self …

And then he understood what the creatures were doing, and the opportunity became almost at hand; for the queer metal devices in the chamber were weapons!

He even understood what they needed a human being for. The weapons were ill-suited to their owners. “Owners” seemed the wrong word, in fact; the creatures were almost as awkward with them as Tupaia himself, as if they had never seen them until just recently. Certainly the handles and grips and levers were designed for beings with fingers and hands—although not, perhaps, the fingers and hands of human beings. Tupaia’s fingers were too short, and the grips seemed made for creatures with more than a single thumb. Yet he could manage, and they could not. They ordered him to pick up one of the pieces, a silver-gray onion-shaped device, a globular mass coming to a sharp point at one end; it had a double butt, making it even more awkward. When he raised it to his shoulders it was too narrow to fit properly on his huge torso, and his clumsiness with the finger grips made the alien creatures scatter in consternation.

That was when he realized it was a weapon. They snatched it away from him and jerked the Pmal off his neck, gabbling among themselves in hiss and drum-roll and screech. Without the Pmal he could not understand a word—as they had intended—but he didn’t care. His mind was bursting with the realization that here was a chance he had never dreamed of. Weapons of an alien science! If he could steal them— If he could get them to the tachyon transmitter and smuggle them back to Earth— If he could evade the guards at the Tachyon Center and deliver them to the other warriors in New Guinea or Rabaul—

There would be a way. There had to be!

But it was slow to appear.

They kept him there for endless hours, without rest or respite. They threw the Pmal at him from time to time, long enough to convey quick, curt orders commanding him to manipulate strange controls on even stranger devices, then retired once more for their interminable secret gab­bles. After the first time they were wary of letting him have free access to a hand weapon, and even warier of some of the huger, stranger devices. But they had to learn how to operate them, and he was their only learning tool. There was a device like an organ keyboard attached to a great, solid, translucent block; under their instructions he pressed keys and twisted curious, helical levers, and for a long time nothing happened.

Then something did.

The glassy block began to light up with an eye-searing pinkish glow, while a thin, high sound grew louder and deeper, running down the scale. The aliens reacted with quick fear. The Sheliak’s tentacles snatched Tupaia’s fin­gers off the keys while the robot lunged at what seemed to be the starting switch. For a moment Tupaia thought they had been too late, as the glow built higher for a second. Then it wavered, faded, and disappeared.

They never let him touch that one again.

While they were debating, Tupaia became conscious of bodily needs. He approached the Sheliak, took the Pmal, and through it asked for food, water, rest. The answer, once again, was the Pinal’s equivalent of contemptuous laughter. Tupaia stolidly let them take the translator away. His time would come. He would make it come.

He could find nothing to eat, but there was a globe of a thin, sour liquid enough like drinking water to serve, and a corner in which he relieved himself. The aliens paid no attention. He squatted by the door, watching everything, seeking the vagrant thoughts that would turn into a plan. He was certainly in a far better position than when he had been owned. The purchasers of Purchased People generally treated them as expendable. If they wanted to eat or sleep or relieve their bladders, they could. As long as there were no prior orders from the owner. Which was seldom. Here the only force imposed on him was physical. And by com­parison, physical constraints were nothing.

After Tupaia’s arrest and conviction, it had been only a few days until the prison authorities had struck their bar­gain for another batch of convicts sold to the aliens. Which aliens, or for what purpose, no one seemed to care. There had been a brief surgical operation—strapped immobile to the table Tupaia could not see what was happening behind his ear, or feel more than an itching tingle through the local anesthesia—and then the owner was inside his head. Terrible! It was not like one-to-one communication. The owner was immeasurably distant, and even tachyons took finite time to traverse interstellar spaces. But it laid its geases on him, and sampled his senses, and it was always there …

He was allowing himself to daydream!

He roused himself just as the screeching and rattling of the aliens rose to a high pitch and stopped, and they turned back to their project. Tupaia watched carefully as the Scorpian and the Sheliak examined the hand weapons. The robot picked up the onion-shaped weapon apprehensively, while the Sheliak nervously hissed advice. If they were foolish enough to put it in his hands again, even for a mo­ment …

That foolish they were not.

As the robot awkwardly fitted his clawlike metal feelers onto the grip and braced the twin butts against his metal body, the Purchased Person, Te’ehala Tupaia, realized tar­dily that he was meant to serve more purposes than one. Not just to help them learn how to operate the weapons. To do something more important still. Because how could you know if a weapon was effective until you tried it on a liv­ing target?

The onion-shaped globe came up with the point aimed straight at Tupaia. A greenish glow sprang out around the globe, collected itself toward the tip, launched itself toward him.

As the green blob of light spun toward his head he real­ized that he had waited too long to make a move; and that was the last thought that ever flickered through the mind of that particular Te’ehala Tupaia.


I wake, and the waking is not easy this time. For I am afraid.

Something is moving inside the sacred structure of HIS being, shielded from my knowledge and my control. Some­one is prying into the forbidden secrets, seeking powers that belong to HIM alone. Someone is discovering the se­cret state of the matter that can exist as neither solid nor liquid, gas or plasma, but forms into atoms larger than stars. Someone is using the old weapons to violate HIS pre­cious fabric itself.

It is someone who does not belong to the chosen slaves. Someone has no right there, who can be there for no prop­er purpose.

I am deeply troubled.

I cannot penetrate the mind shields the blasphemers have invented, even to determine their race or their loca­tion or the extent of their unholy aims.

Shall I wake HIM to expunge them? Dare I?

I hesitate. As I rouse and survey the widening spheres of contact I see that there are others to follow, and others beyond them. A thousand times a thousand times I have been aroused from sleep to swat an annoying insect or fumi­gate an erring world. But never before has anyone been so deep in the forbidden places, never shielded so well from my senses.

I must not disturb HUM until HIS time shall come.

Yet now HIS time draws near. On the myriad worlds, my myriad servants are preparing for HIM. The world ma­chine HE dreamed and planned and built is reaching the fulfillment of HIS supernal purpose. HIS moment will be soon.

It will arrive in time, I decide, for HIM to defend HIM­SELF. For when HE wakes, all such would-be desecrators of HIS work will be consumed into HIM. No shield can hide them. No weapon can defend them. All beings every­where will be drunk into HIM.

That is what I fear.

For I myself, like all others, will be engulfed into HIS awful immensity.



In spite of its shape the flexible helmet slipped onto Jen Babylon’s head with great ease. It did not interfere with his breathing. It was not uncomfortable. It merely blanked out all sensation. He saw no light, heard no sound; it was as though he had poked his head into a pool of utter, silent blackness. He felt Redlaw, or someone, fiddling with the coppery metal at the top of the helmet— And then he was somewhere else! He was in a great, dark chamber, and his first sensation was of nearly lethal fatigue. He was carrying a device he had never seen before, and a huge creature, three great eyes blazing like emerald headlamps, was flapping long, feathered wings in slow time before him. Piercing the swol­len body was a sharp-tipped spear. An alien of a type he had seen before—a deltaform, a flying species shaped like the triangle of an ancient supersonic aircraft—shrieked over his head. The deltaform spun back toward him. Baby­lon felt a sharp stab of fear— And was something else.

All his senses shifted; they were blurred and broken and, though he tried to find his own person, he could detect nothing human. He wore the shape of a deltaform! He was slithering down a dark, twisting passage, like the gut inside some dinosaurian beast. Things were following him, things no more human than himself. He heard the clatter of their chitinous shells against the narrow walls and smelled their rancorous stink, and knew what they were. Watchers! Armed Watchers, a combat brigade of them; and under his command—

 The wink of an eye; and he was in a different place. He was less fatigued this time, but still in terrible pain. Something serious had happened to his leg, and when he glanced down he saw that it was bleeding and suppurating through a hastily tied rag. He was operating a drill, cutting anchor holes in a body of rock under the distant glowing clouded sky of Cuckoo. His body seemed queerly out of focus—unfamiliar—and he realized with a shock that it was the body of a woman. He was terribly, numbingly cold, and though his hands wore thick gloves the rest of his body—of that female body that he now inhabited—was suffering damage …

Gone again. And now he was in a lander, crushed in some catastrophe moments before. Through a broken win­dow he saw a landscape whipped under a howling wind, bathed in soft, rose-colored light—gone again!

He was leaping across a great green meadow studded with trees that glowed with a crimson radiance. Undulating and endless, the meadow stretched from forever to eternity before and after. He came down, in Cuckoo’s slow, gentle pull, near one of the trees, flexed his legs to spring again— and became aware of a choking sweetness from the tree that paralyzed him for a moment. He sprang weakly, coughing and strangling—

And was gone again. A Scorpian robot and a Watcher were shouting to him in a language he didn’t understand; the Watcher’s evil beetle stink made his stomach twist. A cloud of bioluminescent midges obscured his vision by dashing themselves into his eyes—

Another place. He was sailing on a blood-colored wave- less sea, smooth as oil. Babylon felt a gnawing pain in his lower limbs, and once again it was not merely the pain itself but the odd inability to locate it in his familiar body that made it terrifying. But he could not look down. He was holding the stock of an immense crossbow weapon, and his gaze was not allowed to deviate from the sights, or from the approaching sailing vessel that was his target. It was less than five hundred meters away, then less than four, swiftly cutting in toward his own ship. Its tall masts were oddly curved, and the smooth black sails seemed to grow from them, with no rope or yard. The hull swelled smoothly with only a narrow space that could be a deck; two greenish spots near the prow looked like luminous eyes—

It was alive!

At that moment his muscles were commanded to fire. The crossbow launched its quarrel, a wedge-shaped bit of metal that glowed and sprang into brilliant purplish flame as it left the weapon and exploded into the side of the black ship. In that moment the iron control over his body relaxed and he could look down. The curious imprecision of the pain explained itself—he was not in a human body! What­ever he was, it had a chitinous shell and a dozen furred, spidery legs; and, most terrible shock of all, the ship he was on was alive as well, and tiny mouths, opened on the deck, were gnawing at him—

Gone once more. Babylon had lost control completely now. He could not say at any moment where he was or out of whose—or what being’s—eyes he saw. It became a flick­ering kaleidoscope, giant trees kilometers tall followed by red-lit thundering caverns, black balloons that trailed living ropes toward him, and tiny creatures like treefrogs under­foot, mewing piteously as he crushed them. For a moment he was on a plain with half a dozen other Purchased hu­man beings, cowering in a hailstorm, pellets as big as his head, under a thick snake of twisting cloud pulsing with scarlet lightning, and then he was in a chamber, a Scorpian holding a metallic mechanism of some sort from which a blob of green light grew and spun toward him. He had just time to realize that he was in a human body again, taller and healthier than his own, when the green blob struck.

In agony he wrenched the helmet away, and crumpled, half fainting, into Zara’s arms. “I think that time I died,” he gasped. “My God! What things I saw!”

Doc Chimp hopped over with a bulb of something to drink—something that made Babylon sputter and gasp. “Just my own home-made jungle juice, Dr. Babylon,” the chimp apologized, “but I thought you’d need it.”

Babylon breathed hoarsely, then nodded. “I saw—oh, what did I not see! Things I never dreamed of! Places I never knew existed!”

Zara gently freed herself and nodded. “That’s the whole thing, Jen,” she said. “When you put that helmet on, you’re seeing through the eyes of Purchased People all over Cuckoo—some of them not human. And you’re see­ing things that are not in the synoptics! Things that there is no record of anywhere!”

“But how can that be?”

“Treachery!” Redlaw boomed, his red beard waggling with indignation. “Somebody—some races—are up to pri­vate activities that they keep secret from the rest of us! They’ve got an unregistered tachyon communicator; they’ve employed Purchased People without recording them. When I put that helmet on I saw places and things that I had not even suspected—and I was born on Cuckoo, Babylon!” He snatched the dataglobe out of Doc Chimp’s stereostage, added it to a pile of hexagons. “Here, Babylon! You’ve got the only equipment to play these things—study them! Try to find out what they mean! And, above all, don’t let our enemies know what you’re doing!”

Babylon accepted the objects, running his fingers over them as though in that way he could plumb their mysteries. “How do I know who the enemies are?” he asked.

There was silence in the chamber for a moment. Then Redlaw laughed harshly, a sound without amusement. “If only any of us knew the answer to that!” he boomed. “So tell no one! No one but the T’Worlie and the people in this room!”

The hardest part was convincing the T’Worlie that se­crecy was important. It was against all their age-old in­stincts. For more than a million of Earth’s years the T’Worlie had thought their long, slow thoughts about the nature of the universe; had sent their slow probes around the Galaxy and outside it; had methodically measured and observed and assessed—and had shared every datum and every thought with all who would listen. Before Mimmie could understand what Babylon wanted, he required pain­ful explanations; before he could agree to it, he had to con­sult with the wisest and oldest of the other T’Worlie on the orbiter. They filled the little chamber with their soft, winged bodies and the smell of their discourses with each other—singed hair, burnt sugar, wood violets, now and then an acrid sulfur reek of dissent. Babylon could recog­nize his colleague, Mimmie, by the pattern of dots on the filmy wings, but the others—all those others! They had names like Nleem and Mlim, Nlem, and Nloom, and they squeaked and whistled at each other far faster than the Pmal could translate.

Babylon left them to it, curling up in a corner of the chamber for an hour’s sleep. When he woke up he and Mimmie were alone. He stretched, yawned, and asked, “What’s the verdict?”

The TWorlie whistled gently, “Concurrence. TWorlie have agreed to play this game of your devising, Jen Baby­lon.”

“Thank you,” said Babylon, although he was not entirely sure he was grateful. “Game?” Perhaps everything the younger, shorter-lived races of the Galaxy did seemed a game to the T’Worlie, though the games that were being played around Cuckoo seemed particularly nasty. And pointless! What possible advantage could any species get from damaging the cooperative effort?

But then, generations of human beings before Jen Baby­lon had asked that question of their own species, and never found an answer. He grinned and bestirred himself. The TWorlie had not been idle while he slept. The stereostage was displaying some of the views Redlaw had brought back from the temple by the lake, and as he approached, the TWorlie dexterously scanned through to find the one he was interested in, then rotated it so Babylon could see. “Query: Have you observed this star formation?”

It was the interior of the building, with the image of the galactic cluster glowing from above. “Yes, Mimmie. I don’t know how old it is, but it’s remarkable that it still has power enough to radiate now.”

“Observations. First, concur; estimate age not less than one hundred thousand your years, upper limit much higher.” And before Babylon could react to that: “Second, observations and analysis of stellar configurations and types indicate no match against known galactic configura­tions. Conclusion: representation of galaxy not our own.”

One more puzzle! But there was not time to dwell on it, there was so much else to worry about. Babylon set aside the question of just who had made that model of a galaxy in favor of the puzzles that were nearer at hand. Why was there no response from that other Jen Babylon on Earth? Who were the beings who had furtively sent Purchased People all over Cuckoo—and why had they done it? Who were the “enemies”—and what were they up to?

And even those questions, which had no answer, drifted into the background of his thoughts as he and the TWorlie began trying to decipher the new lot of hexagons from the temple.

It was not difficult to make them work. They were of the same design as the ones from the wrecked spaceship, fit as readily into the reader they had brought back into the orbiter. But when they were read, what did they mean? Some were star patterns. Some were what looked like wir­ing diagrams and structural sketches of a ship like the de­stroyed one. One whole series showed a sort of bestiary of galactic races, and some that were not galactic, or not rec­ognizable as such—the TWorlie cooed softly over these, and made copies for the other TWorlie who specialized in the taxonomy of cultures.

And one hexagon was a total puzzle.

They slipped it into the reader over and over and watched the cube fade, become transparent, light up. What it showed was always the same. A bright disk with dark behind it. A sun, perhaps, as seen from a billion kilometers away. Or a white-hot dime at half a meter, for there was no key to its scale. Alone at first, but suddenly with a thin ring around it, blue and bright-shining, placed like a plan­et’s orbit if it had been a star. A second ring, almost at right angles. A third, and suddenly many, weaving them­selves into a wickerwork ball with holes where the poles would be if it had been a planet. Something darker spread over the blue ball. Sections sliding together like pieces of peel replaced on an orange, forming larger sections— finally forming octants like those puzzling octants on the map of Cuckoo.

They played it over repeatedly, the TWorlie dancing be­side it, swooping to study it from all angles, Babylon paus­ing to munch the dreary synthetic food that kept him alive and returning to study it again. “One thing’s certain,” he said at last. “It’s a machine of some kind, and we’ve never seen anything like it.” The TWorlie did not answer, but Babylon detected a faint wintergreen odor of polite doubt. “That object at the center. It looked like a star. Don’t you agree?”

The TWorlie hesitated, then whistled diffidently: “De­murrer: scale not established. Hypothesis: possible repre­sentation of submicroscopic object that we do not recog­nize.”

Babylon nodded. “If the thing in the center were a star—oh, but of course it couldn’t be. Nothing could be that big! I guess it could even be an atomic particle. Maybe a theoretical diagram for the structure of a quark. But more likely it’s larger. Some kind of construction. Could it be—”

He frowned at the fluttering T’Worlie.

“Could it be some kind of advanced spacecraft, with the sun-thing a power source? Look, those polar openings have raised hps around them. Nozzles, maybe, for some sort of plasma jet, if the object could really be a vessel.”

Hesitant lemony smell of uncertainy from the TWorlie. “Conjecture not excluded,” it agreed. “Contraindication: no evident space for passengers or payload.”

Babylon shrugged irritably. “How do we know it’s sup­posed to carry anything? It could be just a—I don’t know, a toy!” He shook his head moodily. “Hell with it. Let’s take another look at the biological series—those human-looking bipeds still bother me!”

They were not left alone. Doc Chimp looked in often, Org Rider and Zara from time to time. Even Ben Omega Pertin roused himself from his hiding place to skulk through the corridors once or twice, then quickly retreated to his privacy—and his vices. The worst interruptions were the peremptory visits from beings other than the humans or the TWorlie. Three horse-headed Canopans spent an hour listening to the tapes from the wrecked ship and demand­ing letter-perfect translations—without getting them, of course, since they didn’t exist. A Sirian came at unpredict­able hours, shaking the door with the spattering electric discharges that were his substitute for a knock, never stay­ing very long, never explaining. Each time there was the great nuisance of having to get the hexagons out of sight and all their notes and drawings under cover. At least they were spared the Scorpian robots, and, above all, the Watcher—

“Though we probably could use him now,” Babylon told Doc Chimp. “There are whole new audio tracks we haven’t played for him.”

“You’ll never find him, Dr. Babylon,” the chimpanzee said. “As soon as he found out what that temple was, he was off. I don’t know where. Maybe down on the surface to see for himself. Maybe still on the orbiter somewhere— you could hide a hundred Watchers for a hundred years in some of the E.T. zones!” He moodily spun the controls of the hexagon reader, looking at the cryptic hollow sphere. “Can’t you just match up the words you know against the tapes?” he asked.

“Of course we can. Of course we do, Doc! That’s the basics. But it’s not enough. Similar words—even the same words—don’t mean genetic relationships between lan­guages. There may be no interaction between the speakers, but a common source. Perhaps the people who built the temple and the people of the wrecked ship are not the same. They might still have occupied adjacent linguistic areas—were neighbors, say, or influenced each other by travel or commerce or conquest. Or were themselves lin­guistically ‘adjacent’ to some unidentified third race, from whom they borrowed words. You find loan-words in ter­restrial languages all the time. The Japanese use the French pain for bread; their words for baseball, and tele­vision, and chocolate are almost identical to the English. But the languages have almost nothing else in common.”

The chimp stared at him with woeful shoe-button eyes. “What you’re saying is we haven’t learned anything at all?”

“Oh, no! We’ve learned a great deal! We can identify some of the graphics from the wrecked ship—that’s how Redlaw was able to find the other hexagons. We can even make a shrewd guess about the history of Cuckoo!”

“Really? Come on, Dr. Babylon—”

“No, it’s true,” Babylon insisted. “Putting it all together, we can say that the races akin to the galactics arrived here some time around thirteen thousand years ago; anything before that was original. We can say that the Watchers seem to be original, and that the language they used in communicating with the unknown race they Svatched’ for has cognates with the language of the ship. Now, when I get the data from Boston, and when I can feed it all into the farlink computer, then we’ll know a very great deal.”

“Will we know what’s going on?” Doc Chimp asked, grinning.

“Well, we won’t know why somebody’s using Purchased People secretly, “Babylon confessed. “Or why some of the races seem to be sabotaging our work. Or why—”

Doc Chimp raised a leathery paw. “Or why we’re here in the first place,” he finished. “Ah, me. It is not an easy thing to bear, the Primate’s Burden!” He sighed theatri­cally. “Everything has its price, doesn’t it, Dr. Babylon? Simply because we primates are so marvelously well adapted to anything, anywhere, we are the most popular Purchased People in the Galaxy, as well as the envy of all other races for possessing the Galaxy’s most distinguished linguist—”

Babylon shook his head, marveling at the little creature’s abrupt swings of mood. But it was pleasant to have the atmosphere lightened. “The only reason,” he said, “that the rest of the Galaxy considers us linguists is that we’re so backward. Do you know what they call us? ‘The only race that cannot communicate with itself—because of our twenty-five hundred separate languages!”

“You are too modest, Dr. Babylon!”

“And as to being the race that sells best for Purchased People,” Babylon added, “I can’t help think those aliens are making a mistake using humans. Chimpanzees are so much better! Stronger, more agile—oh, now what’s the matter?”

The little creature’s long lip was trembling. “There are some things, Dr. Babylon,” he declared, “that it is wrong to joke about! Purchased People are criminals. Chimpanzees do not become criminals. You’ll never hear a bunch of law­yers arguing about whether the civil rights of convicted chimps have been violated!”

A scent like singed hair reminded Babylon of the TWorlie, dancing silently between them as it listened to the discussion—he could not decide whether the aroma meant curiosity or tact. “Query,” it whistled. “Define ‘civil rights.’”

Whether it was tact or not, Babylon was glad to change the subject. “Why, they’re the right of every person—of every entity, I mean—to enjoy certain inalienable rights, such as life, liberty, and the pursuit of happiness.”

The creature was silent for a while, then whistled slowly, “Incomprehension. Query term ‘inalienable’ if rights can be ‘alienated’ as in case of ‘criminals.’”

“Oh, that’s easy to explain,” Babylon said quickly. “You see, every human has these rights, but he must not, of course, violate the law. For example. Among the criminals who were being transmitted when I was were, I believe, a Polynesian who advocated revolution against his lawful government, a woman guilty of failing to pay taxes, and any number of people convicted of other crimes.” The singed-hair aroma was stronger than ever, and the T’Worlie said:

“Request: Define term ‘taxes.’ Define term ‘govern­ment.’ Define term ‘advocated revolution.’ “

Babylon hesitated, and was saved by an interruption. Zara’s voice called from outside the door, “May I come in?” Doc Chimp hastily opened the door for her and she entered, bearing a fiber bag of some lumpy objects.

If Babylon had had any desire to continue the conversa­tion, Doc Chimp’s behavior put a stop to it. The little mon­key’s nostrils were quivering, and so were his skinny arms and legs. “Oh, Zara!” he cried piteously. “Do I smell what I think I smell?”

The woman, smiling, said, “Why don’t you see, Doc?” and held the bag out to him. Doc Chimp seized it greedily, poked his head into it, and emerged with an immense grin. “Oh, bless you, dear lady!” he cried, spilling the contents into the air. “You know how us monkeys like bananas!” And indeed what came out of the bag was two huge clus­ters of fingerlike yellow fruit.

“They’re not true bananas,” Zara said apologetically. “At least, they didn’t come from Earth; Org Rider had them shipped up in a drone from his home hills, along with our regular grocery list. I think they probably came originally from the Earth, but a long, long time ago—just like Org Rider.”

“Don’t apologize, dear Zara!” Doc Chimp cried happily, his voice muffled as he peeled back the skin and thrust the first of the fruit into his mouth. “They’re good enough for me—and the best thing that’s happened to me in a month of Sundays!”

“What I really came about,” Zara said to Babylon, “was to see how you were coming along. According to Org Rider, time’s getting short.”

The T’Worlie danced nearer and peeped. “Query: Please state reason for opinion.”

Zara’s expression clouded. “I wish I could be sure,” she said, with a troubled note to her voice. “Ben Pertin—that’s Ben Omega Pertin, as he calls himself now—has been fill­ing Org Rider’s ears with all sorts of rumors. Weapons test­ing in the outer chambers of the orbiter. Stories about the Watchers Unking up with the Scorpians and the Sheliaks. Even something about a human corpse turning up in the refuse for the plasma chamber—but it’s all just rumors, and Ben won’t talk to me himself.”

Doc Chimp grinned over a mouthful of banana. “I’m not surprised at that, Zara,” he remarked wickedly. Whatever the reference was, it escaped Babylon; but Zara did not elucidate, Doc Chimp did not pursue it, and in any event he was having trouble keeping his mind on the conversa­tion. His mouth was watering.

He cleared his throat. “Do you, uh, do you think I could have one of those, Doc?” he asked diffidently.

The chimp looked alarmed, then repentant. He started to offer one of the hands to Babylon, but Zara stopped him. “Jen,” she said, looking at him closely, “you know what? You actually look hungry!”

He smiled, embarrassed. “Well, this synthetic food keeps you alive—but I really could use something better,” he ad­mitted.

“Oh, Jen! I’m so sorry. I should have thought. Tell you what,” she said, nodding. “Org Rider’s cooking up some­thing right now out of the stuff we had sent up in the drone. Why don’t you come have dinner with us tonight? It’s nothing fancy—but a lot better than the synthetic stuff, and you look as if you could use a square meal!”

Zara and Org Rider’s compartments were no more elabo­rate than Babylon’s own, if a trifle larger—they had three separate rooms, while he had only one. But they had made them their own. On one wall was a replica of the great picture of Knife-in-the-Sky mountain that Babylon had seen before—in Pertin’s room? Somewhere. On another a moving holo of the temple by the lake, with luminous clouds scudding overhead and gentle wavelets on the water. There were personal trophies fixed to every wall—a bow and a quiver of arrows, a great rough diamond Zara had found lying at the edge of a stream, a small holo of a winged creature, slim fishlike shape of bronze and silver. Strange thing to keep! Babylon thought, but only with the outer fringes of his mind, for most of his consciousness was terribly focused on the marvelous, rich, hot, savory smells that were coming from the corner where Org Rider was tending their meal. “Pity I have to use resistance heat,” he said over his shoulder, turning the huge chunk of meat on its spit. “It’s much better over an open fire! Puffballs and fire-tree wood, nothing better to give the meat a taste! But Zara won’t let me.” In a heap in the waste receptacle was the refuse of the meal; it had started as a sort of immense grub, and Org Rider had expertly split its shell and popped the round, raw meat out of it while Babylon watched, re­pelled and fascinated. They were going to offer him roast bug for dinner! But as soon as it began to cook all those thoughts were dispelled.

And the reality was even better than the expectation. The roast creature was delicious, and with it was a sort of puree of what had started out as leaves and roots but tasted like delicate fresh garden produce, and fruits and nuts of a dozen kinds for dessert. For the first time since he arrived on the Cuckoo orbiter, Jen Babylon felt as if he had not merely refueled but dined. Org Rider accepted his compli­ments complacently. “Just plain hunting fare,” he pro­tested. “We ate this way all the time when I was a boy— when we ate at all,” he added, laughing. “I don’t want you to think it was heaven! But we did have freedom, and a chance to roam the world—that very huge world down there, which none of us could use up if we lived a thousand years. And then, when I got my org—” He looked sadly and affectionately at the holo of the winged creature. “You don’t know what that meant in the life of a young man of my tribe, Jenbabylon.”

“It does sound a little like heaven,” Babylon commented. “And you obviously miss it.”

“Oh, no! Not really! Or anyway,” Org Rider qualified, “only when I’ve been too long on the orbiter, or in a lander, or spending time with those stinking Scorpians and She­liaks. But Zara understands! And I wouldn’t trade her for a hundred orgs—well, for a dozen, anyway,” he grinned, affectionately patting her slim shoulder. Then he roused himself. “I suppose you’d like some real coffee? I thought so—can’t stand the stuff myself, but Zara likes it. I’ll pass. I’ve got an errand to run.”

Zara spoke up. “Tell him, Org Rider.”

The stretched-out man shrugged, a sinuous movement that seemed to take twice as long as with a normal-sized human being. “It’s not a secret—from you at least, Jenbab- ylon. I’ve got to see the Omega Pertin. He’s been sneaking and spying around again, and he wants a meeting with me. I’m sure it’s nothing. —Well, not as terrible as he seems to think, anyway,” he amended. “But I’ll find out. I don’t think I’ll be gone more than an hour or so—take your time with your coffee, and we’ll see if I can find anything bet­ter to drink when I get back!”

Zara rose to kiss him as he left, then returned to Baby­lon. She listened politely but without any sign of close at­tention to his complimentary remarks about the meal and their home. Something was on her mind. When Babylon realized that, he occupied himself with a long, marvelous sip of his bulb of coffee to give her a chance to get it out.

She plucked at her tunic as if she were having difficulty finding the right words, and then said, “Jen?”

“Yes, Zara?”

She gave him a sudden smile. “I’m embarrassed,” she confessed. She was a strange-looking human being, atten­uated so that she towered over him—but a beautiful one, Babylon thought. And most of all so when she smiled. “It’s nothing, really,” she said. “Or—that’s not true, either. Oh, hell! Let me come right out with it. The other Zara back on Earth—didn’t you say she had a child?”

“That’s right, Zara. A little boy. Eight or ten years old, I should imagine—very nice little boy, allowing for the natu­ral tendency to get into mischief.”

She nodded. “I assume it’s Don Gentry’s child?”

“Well, I didn’t really know her, Zara, but, yes, I think that was her husband’s name.”

She grinned. “My husband’s.”

“Yours?” She had caught him unaware. “Oh, I see what you mean—you are, after all, the same person! Just as I’m the same person as the one back in Boston who won’t an­swer my requests for help! It’s a little confusing, keeping track of who is who.”

She laughed out loud. “You think it’s confusing? But there are only two of you! And of me—heaven knows how many. But Don and I did get married, back on Earth, and then the two of us came here together. But—he was killed. And then I met Org Rider. He’s a wonderful person, Jen, so simple and strong. And, to tell the truth, Don and I weren’t getting on that well together, even after we came here. So I’m a little surprised that we had a child together.”

Babylon said diffidently, “Didn’t I understand that you were also married to Ben Pertin?”

Her laugh was tinkling. “Not to any of the Ben Pertins you know, Jen. You see, the first time I was tachyon- transmitted, my duplicate went to Sun One. That’s thou­sands of light-years away, in a completely different part of the Galaxy from Earth. I hadn’t even met Don Gentry when I went there. So on Sun One I met that Ben Pertin, and we got engaged. After he was tachyon-transmitted here I married the one who stayed behind. And I—that I on Sun One, I mean—had a child, too. A little girl. I have a pic­ture of her,” she said wistfully. She leaned forward and put her hand on Babylon’s arm. “Come on, Jen! Tell me what I want to know. What’s my son like?”

Touched, Babylon paused, trying to remember. One little kid was a lot like any other to a bachelor. “He was … a young boy,” he said lamely. “He seemed like a bright young man. I remember he got in trouble with his mother because, naturally, he was interested in everything that went on. So he wandered off when she wasn’t looking. She gave him quite a talking-to when he turned up again, but I don’t think she was really worried—he gave the impression of being unusually able to take care of himself.” He paused, then asked directly, “Why don’t you ask her—I mean ask you, that other you? I’m sure she’d send you a holo at least!”

Zara looked pensive. “Maybe I should,” she said. “After all, why not? Although we’ve sort of lost touch … Well, I’ll tell the truth. It’s embarrassing, Jen! That’s one of the confusions. When your husband dies you’re a widow; that’s simple enough. But what if in some other place he isn’t dead, and you’re still married to him? It’s simply too com­plicated to handle, Jen.” She stared unseeingly at the holo of the org for a moment, then nodded decisively. “Yes, you’re right! I should ask her. It’s nothing to do with Don and me. It’s only a question of motherhood, and she’ll un­derstand—I mean I’ll understand!” She was laughing now. “Oh, Jen,” she said warmly, “you don’t know how grateful I am to you for this talk!”

She was very close to him, and suddenly the fact that she was sixty centimeters taller than he didn’t seem to mat­ter. How long had he been at Cuckoo? He had lost count, but long enough—certainly long enough for him to be un­comfortably aware that she was a very attractive woman, and Sheryl was very distant and very far in the past.

There was, of course, always the question of Org Rider.

On the other hand, who was Org Rider that he should worry about him? Somebody who’d cooked him a dinner, period. Jen put his arm around her shoulder. Ambivalently. Because she was feeling emotional, and needed a fatherly, brotherly, soothing touch; or because, in quite a different way, the emotional feelings were his own. It was an all- purpose arm, to be defined by the way she reacted to it; but the reaction was never given a chance to develop. “Gentlefolks?” called Doc Chimp’s high, giggling voice from the door. “Am I welcome? Do I smell more ba­nanas?”

Zara rose easily and let him in. “Of course you’re wel­come, Doc,” she said. “No bananas, I’m afraid. But there’s other fruit, and Jen and I were just having coffee—you’re certainly welcome to join us!”

“Coffee, oh, my, yes!” Doc cried, his eyes glittering at the net bag of fruit. “And aren’t those pinkish things the ones that taste like plums? Yes, please! But just a few, and then we’ve got to go, because Org Rider wants us all down in the lander sector in half an hour.”

Babylon cleared his throat, not yet quite adjusted to the sudden interruption of the tete-a-tete. “What for, Doc?” he demanded.

“Oh, some nonsense of Ben’s, I believe,” the chimp said airily, managing to squirt a swallow of coffee through one corner of his hps while cramming the soft-skinned pink fruit into the other—and to speak at the same time. “Did I interrupt something? What were you talking about?”

“Certainly notl” Babylon said virtuously. “I mean— nothing private, of course. We were discussing Zara’s son, uh, the other Zara’s son. Back on Earth. And I was just going to ask you something, Zara.”

“Please do!”

“Well—I mean obviously you love children. Why don’t you just go ahead and have some?”

Doc Chimp choked on his coffee and squirted a stream of brownish fluid into the wall. Zara stood as if frozen. Her face had absolutely no expression at all.

Obviously he had said something wrong! But what? Baby­lon had no clue. It seemed clear that he owed some sort of apology, but he didn’t know where to begin. And then Zara spoke, her voice as neutral as her face.

“You did say half an hour, didn’t you, Doc? Good heav­ens, what am I thinking of? It’s a long trip to the lander area, and we mustn’t be late. Please. Take your time. Fin­ish your coffee. I’ll go on ahead—you bring Dr. Babylon with you.” And without even looking at him, she was out of the door.

It was only a minute before Doc gulped the rest of his coffee, tucked a couple of fruits in his pouch, and led the way out, but Zara was already out of sight. “Oh, Dr. Baby­lon,” the chimpanzee scolded as he dragged him through the corridors. “Whatever possessed you to say that?”

He caught an endless cable going toward the lander area with one long, skinny arm, the other flashing out to grasp Babylon’s wrist. Babylon grunted with the sudden strain, then twisted to peer at the chimp. “What did I say, for heaven’s sake?” he demanded.

“Telling her to have a child!”

“Oh, I see,” Babylon said, nodding. “She and Org Rider— after thirteen thousand years of genetic separation—not cross-fertile anymore? I should have been more thoughtful!”

“You don’t see! You don’t see anything! Don’t you re­member where you are? Cuckoo! The end of the Universe! The place where forgotten beings rot and decay! There’s not a chance that any one of us can lead a normal life here.”

“Oh,” Babylon said remorsefully, “I didn’t think.”

“No, you didn’t! ‘Ooh, obviously, Zara, you love chil­dren,’ ” he mimicked savagely, his voice rising into a squeaky falsetto. “Obviously she does! That’s why she can’t have any! To have a child here you’d have to hate it!”

“I said I was sorry,” Babylon snarled, and the chimp shook his head and was grimly silent, until they flashed to the end of the radial passage and emerged into one of the great lander chambers. Then Doc Chimp said forgivingly:

“I guess you just haven’t been here long enough, Dr. Baby- Ion. There they are—just don’t do it again, please?” And he sailed ahead to join the little group at the far end of the empty, echoing chamber.

There were at least a dozen of the chambers, each big enough to hold an entire shuttlecraft. Although this one was without an occupant at the moment, it was filled with the gear of shuttle maintenance—great flexible peristaltic tubes, to suck from the lander whatever odds and ends of matter it brought up to replenish the plasma chambers; re­pair units, now slung silent against the glassy walls of the room; the complex locking gear that could open a whole wall of the hangar to space so the lander could exit; fuel pumps; miscellaneous oddments that, to Babylon’s eyes, had no recognizable purpose. To launch himself across that littered space took an act of courage—added to the fact that he was feeling somewhat disgruntled at himself, at Zara, and at the chimp for reproving him. So he took his time, handing himself along the walls instead of leaping straight across the space, and by the time he was nearly there he heard angry voices. No; one voice, and it was Ben Pertin’s, shrill with vexation. He raised it to include BabyIon as he approached. “Take your time!” he sneered. “No hurry! The most important event in the last year—maybe ever—but there’s no reason for you to give up dawdling over your dinner just because the war’s started!”

The strange thing, Babylon thought, was that Pertin was really enjoying himself. Although he was talking to Baby­lon, his real target was obviously Zara, who said, with more patience than Babylon would have expected, “I already told you we didn’t know there was any hurry, Ben.” She gave her husband a cautionary glance. “And we mustn’t argue among ourselves now! Come and see, Jen. It’s true, I’m afraid!”

They were all clustered around a transparent port that showed the next lander chamber—but how different from the one they were in! The lander itself was there, a squat, mean-looking rocket vessel with the hatches open. Around it a zoo parade of aliens were readying it for takeoff. The lander itself took up so much of the space that most of what was going on was out of sight, but Babylon could see great chunks of equipment sliding in for stowage. He had a sudden shock of recognition. “Those machines that just went in! I know what they are! They’re from the wrecked ship—”

“So you’re waking up at last,” Pertin crowed scornfully. “That’s right—weapons!” And Doc Chimp added sorrow­fully:

“It’s the Scorpians again, of course. See, there’s one of them sealing the hatch—and another, with those Purchased People.” He tugged at his long lower lip, his shoe-button eyes troubled. “Oh, what a terrible thing it is to see such treachery and wickedness!”

Zara reached out and patted his narrow shoulder. “I know how you feel, Doc, but the question is, what can we do?”

Ben Pertin laughed sharply. “I thought you’d get around to asking that question—now that it’s too late! Pity you didn’t think of it when you were playing cozy-up with Baby­lon!”

Babylon felt his anger flare, but managed to hold it back. There was something calculated and deliberate about Pertin’s insulting manner, not explained by the whiskey on his breath or his unshaven, uncared-for appearance. This was personal for him, and the one he was aiming the fury at was Zara. Could he still be jealous? Under the circum­stances, preposterous! But something inside Babylon said, True all the same. “There!” Pertin called in sudden excite­ment. “That big hulking Purchased Person there—I could swear he was the same one whose body I saw going into the plasma converter!”

“But if he’s dead—” Babylon faltered.

“Another copy, of course,” Pertin said impatiently. “Look at him for yourself!”

Babylon leaned closer to the pane, crowding Doc Chimp out of his way. The lander’s hatches were closed now, and almost the last of the queer lot of aliens had bobbed, flown, or floated aboard. A great blue Sirian eye hung overseeing the last of the loading, and in the tiny knot of remaining creatures one was human. Tall. Golden-skinned. Eyes downcast, arms obediently wrapped around a great black object shaped like a radar eye; but there was something about his bearing that suggested internal fires and readi­ness quite unlike the Purchased People.

Babylon drew a sudden breath. Of course! He had seen the man before; he was the one who had looked back at him with anger and intelligence, as he was herded out of the Tachyon Base on Earth.

They hung spellbound as the lander closed its ports and the great hatch to the outside infinite opened. The vessel slid out and away. Then Org Rider stirred. “They don’t know everything, at least,” he mused. “They didn’t know I left a tachyon receiver down at the temple.”

Pertin scoffed resentfully, “Score one for our side! And against that, what don’t we know? We don’t know what they’re doing. We don’t know why they’re doing it. We don’t even know where they’re going!”

“I think we know that much at least,” Org Rider boomed peacefully. “To the temple—otherwise why would the Watcher be going with them?” He shook his head. “No,” he declared, “we know more than you think, Ben- pertin. They are going to see if they can find what is under the lake, and if they do I think it will be serious.”

“It’s serious now!” Pertin cried, swatting irritably at something that gleamed and danced by his head—a Boaty- Bit, Babylon realized. “Question is, what can we do about it? I think nothing. They’ve got all the weapons from the wrecked ship, and what have we got? Two scarecrows! A monkey! A bumpkin from Earth who doesn’t even know when he’s in trouble, and—” He hesitated, then finished miserably, “And an old drunk.” He stared out the open ship hatch at the pale blue flame of the distant lander’s thrusters.

There was a moment’s silence. Then Org Rider boomed, “We have one other thing, Benpertin. We have a little time. They’re going by lander, and it will take them time to get there.”

“That’s right!” Zara cried. “We can call an emergency council! Put it before every being on the orbiter—let the sensible ones decide what to do!”

“And who are the sensible ones?” Pertin demanded cut­tingly. “Which ones can you trust?”

“Why, the T’Worlie for one race!” Zara insisted. “And— well—” die hesitated, and the silence grew.

“And maybe not even the TWorlie,” Pertin finished for her. “There’s just one race on the orbiter we can rely on. The human race! —And, of course, other Earth primates,” he added hastily, as he met Doc Chimp’s injured gaze.

“I should think so,” the chimpanzee declared with dig­nity. “I can do anything a human being can do that doesn’t need just mass! Go anywhere. Hide where a human can’t hide, live on what would make a human starve—” He stopped short as he caught sight of a swift change in Ben Pertin’s expression. “Now, what are you thinking?” he de­manded. “You couldn’t— Oh, no! Ben! You can’t possibly want me to—”

Ben Pertin nodded with sudden glee. “You’re absolutely right! You can go down there on the tachyon transporter and be waiting for them when they arrive.”

The chimpanzee laid back its lips and screeched. “Me? You mean me?”

“You bet I do! You can play it by ear—hide and watch them if you have to. Even stroll right out and join them! Say Babylon sent you to, uh, I don’t know—get some more hexagons. Anything!”

“Oh, no, Ben!” the chimpanzee howled. “Zara! Org Rider! Dr. Babylon! Make him say he’s joking!” He stared around at them, then sobbed, “Oh, if you could see your faces— like I was a monkey in a zoo—”

Babylon offered, “It wouldn’t really be you, Doc—just a tachyon duplicate—”

“It’s me, all right! It’s always me! It’s always been me, dying a hundred times, maybe a thousand times—”

“Wait!” Org Rider said suddenly. “What’s the lander doing?”

At almost the limit of vision they could see the vessel— strangely, better now than a few moments earlier. But it was not strange. The lander had suddenly become lumi­nous. It glowed with a greenish color that hurt the eyes, and as they watched the color swelled, clumped toward the nose of the craft, and launched itself at an unseen target. Moments passed.

Then it struck.

Whatever the lander had chosen to test its weapons, it was suddenly limned in green flame. Tiny asteroid, bit of space flotsam—it ceased to exist as the flame brightened and exploded and was gone.

The five watchers each cried out as the searing green stung their eyes, then turned and regarded each other.

Doc Chimp was the first to speak. “When you come right down to it,” he said, “I don’t really have much choice, do I? None of us do. With those weapons getting killed once or twice isn’t going to matter—because they can do it to all of us, anytime they like.”


Te'ehala Tupaia, paramount king-warrior in the forces of Free Polynesia, stumbled out of the tachyon-transporter chamber to take his place in line—

But there was no line!

He was not in the tachyon center on Earth—was not even on Earth! The place he saw was eerily lighted, filled with repellent creatures out of a nightmare; and in it he had no weight! He bobbed like a balloon toward a creature like a huge blue eye, who dodged away with an irritable crackle of electric force, until he was caught by a Pur­chased Person who had been in line with him. He was thrust against a wall while half a dozen additional Pur­chased People came popping out of the tachyon chamber, then they were all ordered to form ranks and move out.

After the first terrible moment of terror and shock, Tu­paia was neither frightened nor confused. He did not know where he was, precisely, but he knew where he had been, in the Tachyon Base in Old Boston, and he knew what that meant.

Even if he hadn’t, what he saw around him would have told him that he was somewhere out in deep space. For not all his companions were human. With him were some, not all, of the Purchased People he had been with in the Tach­yon Base—the very fat man with the huge blue eyes was there, so were the long-haired girl and the youth with the scar blazing white on his terror-stricken face; but at least half the group was absent. To make up, a dozen others had been added. And what others! Creatures like great floating eyeballs, creatures like children’s sculptings of dough, an­gular, metallic creatures that puffed hisses of steam as they chugged along the hallways of this new place.

He could, of course, understand nothing of the screeches and yelps and drum rattles that passed for speech among these freakish beings, but that did not matter. The Pur­chased People were a labor squad, drafted for their brawn rather than for conversation. The queer alien that looked like a lump of baker’s dough when at rest—but was seldom at rest—extended a tentacle and hung something around the neck of the girl with the flowing blond hair. It made a series of unearthly sounds, and the machine around her neck whispered to her in English translation, whereupon she became the gang foreman for these unwilling laborers.

The labor was endless. For what must have been more than a day Tupaia was kept at the tasks of a slave, holding this, lugging that, stowing strange machines and supplies in a great rocket vessel. Now and then he came near a port, and once or twice managed to steal a look outside. A sun, a moon, a planet—anything might help tell him where he was. But there was nothing. Not even stars. Only an occa­sional distant silvery smudge that might not have been real at all. When allowed, he slept. When given food, he ate— strange metallic-tasting stuff that seemed to have come from synthesis vats. A part of his mind was sick with long­ing for the sweet fish, the coconut milk, the papaya-poi of his childhood, but it was drowned in that larger part that wanted only freedom.

At least he was out of the Boston prison! He had been flashed terribly far away, he knew; but that same machine that had flashed him here could flash him back.

He stood erect, almost weightless in the tiny centrifugal force of this object he was in, and his immense barrel chest expanded with the appetite for freedom. It would come! In spite of anything. He did not fear the vile creatures who ordered him about any more than those spastic, hollow- eyed humans who were his labor mates. They did not mat­ter. Tupaia, Te’ehala, paramount king-warrior of the forces of Free Polynesia, awaited the moment of opportunity that would make him free.

But it did not seem very quick to come …

It did not come while they were loading the lander. The hideous aliens were ever vigilant, and the lashing steel ten­tacles of the robot, the scorching electric sting of the huge floating eye proved themselves on other Purchased People. Tupaia learned quickly to avoid them.

It did not come on the long voyage down to the surface of the thing they called Cuckoo. What did come, though, was at least a little leisure, a little time to find which of his fellow prisoners were capable of speech. Most were not, but the young blond girl sometimes, the scar-faced boy more frequently, were willing to talk, almost as human prisoners did in human jails. From them he learned a good deal. They were approaching Cuckoo! Even Tupaia had heard of Cuckoo—no citizen of Earth could have avoided that much. But the flame that burned inside Tupaia had bleached out most other things, and he had had no idea of its size, its distance, or its impenetrable strangeness. No matter. He had discovered that, among the machines and instruments he had helped to muscle on board the lander, some were weapons and one was a miniature portable copy of the tachyon-transfer machine that could flash him back to the orbiter, perhaps even back to Earth. He marked it well. The weapons, even better.

When the aliens discovered that he alone among the dozen Purchased People they had commandeered was not “owned” by some distant creature, there was another ca­cophony of screeches and yelps and confusion as they dis­cussed the finding among themselves. For hours. Finally Tupaia, bored, fell asleep. When he woke the blond girl was staring at him—out of her own eyes, he thought. “What are you?” she demanded.

He said, “I am Te’ehala Tupaia, paramount king-warrior of the forces of Free Polynesia, and I am hungry. What is there to eat?”

She dismissed the question angrily. “Are you with these monsters? Do you know what they plan?”

“I am with them because I have no choice,” he said.

“And as to the rest, I have no doubt you are going to tell me.

“How can you joke? They are playing a dangerous game! They think they can learn all of Cuckoo’s secrets to send back to their home worlds and then destroy it!”

“Perhaps they can.”

“Only if they die with Cuckoo—and we with them!”

“I do not die so easily, woman,” he growled.

“And you are free,” she added thoughtfully. She looked at him almost with envy. “They’re going to have to reim­burse my owner for this,” she explained, “and at least you come free. Nobody cares about you.”

“I come free,” said Tupaia softly, “because I am free.”

“Not really,” she said jealously. “None of us are that!” But he would not argue with her and when, a moment later, that familiar look of sudden abstraction came into her eyes and she moved off on some errand of her distant owner, he was not displeased. The more solitude, the more opportunity to plan. Barring the terrible food, the crowd­ing, and above all the stink—the creature they called a “Watcher” was the filthiest of all the creatures aboard, but each one had its own sickening fetor—he was not dis­pleased with where he was.

Especially since every moment brought him closer to the surface of that great, mysterious world called Cuckoo— huge enough to escape into, he was sure!

They came down at last on what seemed like a white porcelain boulevard in front of a tall, stern temple. The thrusters of the landing craft fouled the boulevard with streaks of scorched blackness and stretches of crazed, heat- cracked porcelain. The aliens herded the Purchased People out at once, and when Tupaia touched the cracked surface it singed his jail-softened feet. He cried out. The blond girl caught him roughly by the shoulder. In a voice not her own she declaimed, “If this unit cannot perform it should be eliminated.” Tupaia muttered something, not caring to look back at what looked out of those mad eyes, and took the hint. He did not complain again.

And had no need to, really. The immense bits of metal and instrumentation they made him carry out of the ship were feather-light in this gentle gravity. They did, how­ever—he discovered—have mass and momentum. He made the mistake of getting between two of them, one a case of synthetic rations, the other a huge, massy, translu­cent block with a kind of organ keyboard attached to it. There was something about the block that flared Tupaia’s broad nostrils and erected the hairs at the back of his neck. Was it a weapon? Had he seen it before? He hesitated, wondering, as the objects floated crunchingly together, and it nearly cost him a leg. He did not do that again. But the work was no challenge for his great muscles.

A great lake. An even greater forest, almost a jungle. Tupaia was desperate to explore either or both, but at first there was no chance. The beings that seemed to be the real leaders of the expedition—the floating eye and the great, puffing cubical robot—disappeared almost at once into the temple. Tupaia could only get quick glimpses of them as they scoured its confines for … what? For something he could not guess at, and did not think they found, to judge from the discontented, rancorous squawks and crackles that came from them. The leathery-winged, foul-smelling Watcher cruised overhead, watching all of them at close range; the lesser aliens toiled with the Purchased humans at slave labor. With three other Purchased People and a horse-headed creature they were set to putting together a raft and loading it with material from the ship. It was hot work in the dank air. All of the humans sweated profusely, and even the horse-headed Canopan exuded great oily drops of a scarlet liquid like blood.

But what a paradise this was! In the moments he could snatch from toil, Tupaia mapped every feature he could see.

All around lay distant, gentle slopes rising up to a ring of far-off cliffs. The slopes were wooded with pink-leaved trees that smelled graciously of cinnamon and pitch. And down in front of them was the great lake. Cool. Clean. It reminded him of the crystal waters of the lagoon beyond the hotel where he had worked as a boy, no more than a meter deep until you reached the distant breakwater reef, with patches of dark coral and the bright underwater lanes where he and the other beachboys raked pebbles and shell fragments away to save the whiteskins’ tender feet. But this was even more clear. He could see no fish or crusta­ceans, just a gentle sandy bottom with a few clusters of marine growth—and the white porcelain roadway. He could trace its outlines as it went straight into the water, descending steeply as the lake deepened until it was lost from sight.

That was puzzling; but the forest was a promise! It would not be hard to hide in such a place.

Tupaia’s courage did not exclude the awareness of dan­ger. There were dangers in plenty in the place where he was and the company he kept. He knew that those gentle woods might conceal dangers more appalling still. The only native life form he had seen was the Watcher; if that was typical of what inhabited Cuckoo, the sharks and orcas of the outer reefs were playthings by comparison!

But dangers were not important. Tupaia’s ancestors had learned to deal with fear. They could not afford to let it rule them. They had crossed the wide Pacific Ocean in hollowed tree trunks, with nothing to guide them but wave crests, a distant sight of clouds—and courage. They had reached, and conquered, islands no human had ever seen before—Fiji, Tahiti, Easter, the great calm archipelago of Hawaii—and Te’ehala Tupaia was their worthy descen­dant.

So he did not fear Cuckoo, or whatever great enemies its forests might conceal. Nor did he fear his companions. Not the stinking, hideous Watcher. Not the Sheliak or the Sirian or the Scorpian robot or the lesser breeds. Not the other Purchased People, catatonically still or in a frenzy of compelled action—not any of them. They were not to be feared. They might even be useful, and if not they could easily die. Te’ehala Tupaia would not shrink from ending their lives at the instant those lives became inconvenient to him.

He became aware of great surges of foul stench, wafted down on him. Overhead the Watcher hung, staring at him with those strange compound eyes. He squealed something peremptorily; the blond girl hurried over and hung her Pmal translator on Tupaia’s broad shoulder.

“You are the one who says he is ‘free,’” the Watcher declared contemptuously, the Pmal faithfully reproducing his speech. Tupaia muttered assent. “For you that word means nothing! You will work as you are ordered. If you fail, you will die. When you are no longer needed, you will die. And perhaps you will die anyway, for I enjoy a good meal!” And it flew away with great sweeps of the leathery wings.

Tupaia swallowed, and returned the Pmal, and for some time was careful to keep his eyes on his work.

They finished fitting the sections of the raft together, then slid it down to the edge of the lake and loaded it with equipment from the lander, for purposes he could not guess … until he saw the blond girl throw off her clothes and step onto the raft. She knelt, shivering, staring out at the water.

When she glanced toward him he saw human fear in her eyes and, for the first time in, at least, some weeks, a hint of human compassion touched him. “What’s the matter?” he asked.

She said dully, “They want me to swim down to the bot­tom of the lake.” Tupaia was surprised. “Why not? It’s not cold.” “I can’t swim,” she explained simply. “I told them that I’d drown. They said it was known that Earth primates possessed aquatic skills, and they don’t. None of them can survive very long under water. The Sirian and the Scorpian would be destroyed at once.”

“Huh!” Tupaia said scornfully, and then, condescend­ingly, “This Earth primate has plenty of aquatic skills. If you get in trouble, I’ll come after you.” Maybe, he added to himself, and then observed one of the other Purchased Peo­ple gesturing furiously for him. He moved off, storing the useful information about the vulnerability of the Scorpian and the floating blue eye in his mind.

Behind him, he saw the Watcher swoop down over the raft, squealing something at the girl. Tupaia cursed him­self. What had he boasted about his skills for? Now they would watch him more closely than ever, because he might be useful!

There were only a few more bits and pieces to load onto the raft, and Tupaia studied them carefully. At least one, he was almost sure, was some sort of hand weapon, a metal object with an onion-shaped barrel and two stocks. When he reached for it casually and the Scorpian robot, with a fierce flurry of drumbeats, snatched it away, he was cer­tain. Good enough! And there were the woods, hardly a hundred meters away …

How far inside would he have to get before he was out of sight—and thus, perhaps, free? Another fifty meters? A hundred? He plotted paths, guessing at his running times, studying likely patches of undergrowth … and then he saw something peering at him out of the very spot he had chosen.

An ape?

That was silly! But he had no time to think of it; be­cause there was a flurry of slow, strong wings behind him and an overpowering reek. The Watcher! He lifted his head just in time to have a metal object strike it.

In Cuckoo’s light gravity it did not drop fast enough to hurt. He caught it easily. It was a Pmal translator, and through it the Watcher’s voice crackled: “You, the creature who is free\ Get back to the raft. We’re going to let you serve us by diving to the bottom of the lake!”

“All right,” said Tupaia, turning obediently—since there was no choice. But he could not help taking one last glance at the patch of undergrowth.

Nothing was there.

He had not imagined it; something had been looking back at him that very closely resembled a terrestrial chim­panzee. None of the others seemed to have noticed it. Or had thought it not worth paying attention to.

Indeed, in some sense it was not. An ape in a jungle? Why not?

Except that this ape had been wearing clothes.

Tupaia emerged from the tepid, transparent water with a shout, exhaling air like the spout of a whale, splashing the side of the raft. The Sirian eye darted away with a crackle of static-electrical fury, and Tupaia marked that confirma­tion down in his memory: the creature feared water. The blond girl leaned over to drape a Pmal around his neck, and the Sirian demanded: “Have you secured the charge?”

Tupaia pulled himself up contemptuously. “Of course.” It was a foolish question, since they already knew the an­swer, for they had sounded the depths of the lake with arcane methods of their own. Radar? Sonar? Something more incomprehensible still? Tupaia did not know, but he could see the glowing virtual image hanging over the center of the raft. The Sheliak extruded a pseudopod to the con­trols, lovingly sharpening the image, but Tupaia had seen it sharply enough when he dove down to the bottom.

The time for escape, Tupaia promised himself, was very close.

The lake was forty meters deep at this point, and Tupaia had been down to the bottom six times. Not to see. To do. It was easy enough to see in the aliens’ instruments what was there: the end of the white porcelain roadway, at a huge doorway of greenish metal. But the instruments could not do what Tupaia had done. They could not carefully attach sticky lugs to the edge of the doorway, could not fix to each of the lugs an explosive charge, could not carry down the delicate fuses that would blow it open. Blow it open for what? That was not Tupaia’s concern. Then, no doubt, the aliens planned to use some other gadget from their bag of tricks that would permit a drone to dive down and enter the water-filled passage beyond—if that was in­deed what was beyond—but by that time their foolish schemes would no longer matter to Tupaia, for freedom would be his!

So he waited patiently, the lake water drying on his bronzed skin, while the Sirian eye and the Watcher lifted themselves into the air, one on a web of electrostatic force and the other by the force of his huge, leathery wings, and flew toward the beach. The Sheliak made last-minute ad­justments, then gave the order to head for the shore. Obedi­ently the Purchased People on the raft sculled it toward the temple.

It was easy enough to pull the raft onto the beach—in this light gravity, there was no such thing as hard work! Tupaia swatted away some sort of steel-blue insect and re­viewed his plans. Yes. This would be his chance. That submarine bomb would create it for him. A huge water­spout—at least a loud noise—there would certainly be some sort of confusion, any kind, enough to let him get into the shelter of the cinnamon-scented trees.

As the Scorpian robot rattled peremptory commands and the Sheliak adjusted the firing mechanism, Tupaia strolled idly toward the tree line. Out of the corner of his eye he saw them trigger the fuse transmitter.

The explosion was a great disappointment.

He could hardly tell when it happened. There was no great spout of white foam, no thundering crash. There were not even bubbles. There was only a small upthrust of gentle, slow water in the middle of the lake, like some great fish disporting itself just below the surface. A distant, mild rumble. Nothing else.

Tupaia swore angrily. No matter! It was time to make his move. He started to spin, to run toward the trees—

And froze. With a snare-drum rattle of fury the Scorpian robot was jetting directly toward him, followed by the Watcher and the Sirian eye … and how had they known?

But they hadn’t known what he was doing. They were not after Tupaia at all. They overflew him, dived into the woods, and disappeared. There were sounds of a scuffle, and then they came back, in line of procession, with the Sirian robot in the middle, clutching, in one disdainful ten­tacle, the queerly dressed chimpanzee.

As they passed, the Sirian eye sent a casual stinging elec­tric lash in Tupaia’s direction, warning him back toward the shore. He had no choice. He obeyed; and as he turned back he heard a sad, whimpering voice: “Oh, please! I wasn’t doing any harm! I was just on a, uh, a scientific expedition—”

It was the chimp! And he was speaking English!

Te’ehala Tupaia could not help himself; he expanded his barrel chest and roared with laughter. The chimp, carried like a rag doll in the robot’s contemptuous grasp, wriggled around far enough to stare down at him reproachfully. Now he was upside down, whimpering with fear, a bedrag­gled monkey in yellow shorts and bright red jacket. Even though it had cost Tupaia his best chance at freedom, it was funny!

And then the humor ended. He heard a strange sound from the lake, and when he looked he saw that it was qui­etly emptying itself.

When the bomb blew out the underwater door, it had not been to connect with some still deeper, vaster body of un­derground water. It had been like blowing the stopper out of a tub. There was a slow, chuckling gurgle from the mid­dle of the lake, as its whole surface began to stir, and cir­cle, and narrow down to a gentle whirlpool at the center. Already the edge of the water had retreated a dozen meters from the beached raft as the lake, with all deliberate speed, drained itself into the empty caverns below.

Two days later the comedy was not even a memory. There was no longer anything for Te’ehala Tupaia to laugh at. Escape had failed. Every hour they were deeper and deeper into the shell of Cuckoo, and the hours were many.

What drove the aliens to this headlong plunge into the depths Tupaia did not know, but the aliens remorselessly drove him, and the rest of the Purchased People with him. They were beasts of burden. Once past the blown-out gate at the end of the porcelain road they were in a narrow, dark tunnel that spiraled down and down. The Sirian eye produced headlamps from one of the containers of instru­ments, tools, and weapons—eight of them for the Earth- primate labor squad, or about one for every other slave. The Scorpian had built-in lights of his own; the Sirian lit his way with coronal discharges of electricity when he needed them, and the other aliens had lamps given to them as a matter of course. Tupaia had one, of course. If he had not, he would have taken it from the nearest other; it was obvious that it was better to have it than not, if one must be a beast of burden at all.

And beast of burden he was, for what he had been made to carry was the great translucent block with the keyboard. Was it really a weapon? He was convinced it was, for the slave drivers kept a special eye on him, the Watcher’s reek never out of his nostrils as the hideous creature soared overhead, except when the Sirian eye or the Scorpian was there. The thing outweighed Tupaia’s own hundred-kilos- plus; on Earth he could barely have lifted it, and he was glad when the aliens commanded other Purchased People to take it in turn.

And they traveled down and down …

It was clear, at least, that this was no natural cave; the walls were metal, regular, with queer niches and protuber­ances that must once have had some function. It was an artifact. And it was immense! It seemed endless, and so steep that even in Cockoo’s forgiving gravity it was hard to traverse.

Worse, it was slippery. The cascade from the lake had gone before them. It had kept on going, to depths unguess- able to Tupaia; but in its passage it had left a coating of slimy muck. Even for Tupaia’s huge strength, guiding the great massy block along the unpredictable jogs and bends of the tunnel was hazardous. At one switchback, damp and oily, the young blond girl slipped and fell headlong. Tu­paia, trying to avoid her, stumbled himself, and would have fallen except that a long, skinny black arm snaked out of nowhere and caught him.

“Watch it, big fellow,” chattered an unhappy voice.

It was the ape, staggering under a load almost as great as Tupaia’s own. Tupaia stopped his block and turned to see him with the headlamp, scowling. The poor creature ducked his head, half-blinded. He was only an animal—

But a king-warrior did not fail to acknowledge a favor. “Here,” he said gruffly, “let me help you with that.”

The chimp sighed, shifting the burden. “Well, thanks,” he said, “but I’m a lot stronger than I look. But if you want to do something for me—”

Tupaia frowned. “What?” he demanded.

“Well, if you’d just shine that light straight ahead for a minute. —That’s right. Thanks! And now at the walls of the tunnel, and then at the stuff I’m carrying—”

Tupaia caught himself automatically doing as the chim­panzee had asked, and stopped. “What’s this about?” he asked suspiciously.

The chimp grimaced with fear. “Please, not so loud! It’s just that I have this tachyon camera. See, this little thing, strapped to my wrist? I didn’t lose it when they caught me—didn’t even drop it, although—oh, believe me—I was so scared! I thought that minute up by the lake was going to be the last this old monkey would ever see!”

“What is it for?” Tupaia demanded, picking up his load once more.

“The camera?” The chimpanzee bared his fangs in a pla­catory grin. “For my friends, you see. They sent me down to keep an eye on this, and I’m doing it. Not that it matters to me, I suppose,” he added, in self-pity, “because the deeper we get the surer I am that this is a one-way trip for old Doc Chimp. But at least they can see what I see— watch it!”

The procession of bearers had suddenly knotted up, be­cause at the head of the group the aliens were squabbling over something again. Rataplan from the Scorpian robot, chitterings and yowls from the others. The ape said appre­hensively, “The one that worries me is the ^Vatcher. The others are just mean. I think he’s crazy! I mean, really insane. There’s something religious about this whole thing for him—he’s looking for his God, sort of—and he’s not finding him, and he’s not sure he should have these others with him. Oh, there’s going to be trouble, I promise you,” he finished sorrowfully.

Carefully, Tupaia set down his ponderous burden again.

“You seem to know more about this than I do,” he said slowly. “What’s it all about?”

The ape sighed. “It’s a long story—”

Tupaia laughed shortly. “We’ve got plenty of time. Maybe nothing else but time.”

Down, down. Now and then they stopped to catch a few moments’ sleep while the aliens wrangled. At long intervals they ate, more of the queer-tasting, metallic, faintly spoiled stuff—in Tupaia’s judgment—all-purpose synthetic food from the tachyon chamber. But it kept them alive.

Escape seemed further away than ever. It was not that Tupaia was lost. Not the descendant of those Pacific ex­plorers! But how could he get away? Always one of the flying aliens brought up the rear of the column, always the others paused even in their interminable squabbling to watch and count the slaves. It was an endless trip, with nothing to do but listen to the ape’s whining complaints and ponder the meaning of what he had said. Tupaia could form no opinion of how true most of Doc Chimp’s stories were. These outlandish aliens were incomprehensible in any terms; Tupaia could make no sense of the chimp’s guesses at their drives and alliances. But he was surely right about the Watcher. That particular creature was growing more agitated and more frenzied at every meter. It carried no light of its own and needed none—when its bulging multiple eyes could not collect enough light to serve, its hideous black ears guided it by sonar like a bat’s—and that made it all the worse. They could not see it coming as it swept back and forth over the ragged slave procession, squealing mournfully and furiously to itself by turns. The chimp’s diagnosis was not to be doubted. The Watcher was mad. And when the line of porters knotted up at a dip in the tunnel where the cascading lake waters had accumulated and left a stagnant pool of thin mud, the Watcher displayed its madness. It came screeching back and struck out at the first in line, the young long-haired blond woman. Tupaia was just behind her. He dropped his burden—fortunately not the block this time!—and turned to face the attack; and something from behind struck him down. His muscles convulsed in a quick tetanic shock. He smelled ozone and his own burning flesh, and lost con­sciousness.

His last thought was that freedom was gone forever, be­cause he was dead.

But about that he was wrong. Broken patches of aware­ness began to come back. He was lying in the dark, his legs still in the slimy water, his body a heavy log of dull pain. He breathed the antiseptic odor of medical foam, and real­ized the chimpanzee had been caring for him. “Oh, Mr. Tupaia,” the animal moaned, “thank heavens you’re com­ing out of it! I thought you were killed!”

Tupaia said thickly, “So did I. What happened?”

“It was that Sirian,” the chimp sobbed. “He must’ve thought you were attacking the Watcher, ‘stead of the other way around—anyway, he zapped you, and I thought you were dead! You wouldn’t have been the only one. There’s two dead already, back in the water—and all the more for the rest of us to carry because of it! Oh, Mr. Tupaia, I’m scared of this place!”

Savior or not, Tupaia was tiring of this preposterous ape and his fretful complaints. But he felt an obligation. “Here,” he said, “I’ll take one of those cases from you—”

“Oh, would you, Mr. Tupaia? Thank you!” The chimp stood up, peering forward in the dim, shadowy tunnel. “I think they’re getting ready to move now,” he said dismally. “I’m afraid your light got wrecked, Mr. Tupaia. But you can see, sort of, by watching the lights up ahead—”

Tupaia did not answer. His weakened limbs were nearly too stiff to move, and the dressings the ape had applied had hardened around his neck and shoulders.

Of course, they might have saved his life, he acknowl­edged fairly. He stood up, setting his increased load in mo­tion, and became aware of new physical sensations. Past the sludgy pool, the tunnel changed character. A coppery, sulfurous odor rose above the medical smell of the foam, and a hot breeze was blowing from below. “It’s a bad place we’re coming to, Mr. Tupaia,” sobbed the ape, and Tupaia

did not have the heart to answer. It was true.

It got worse.

It was days later, perhaps, and certainly many kilome­ters farther along the trail—many kilometers straight down!—when there was a cacophony from the beings at the head of the line that transcended everything before. The temperature had gone up sharply. Every breath was an effort. Tupaia let his load drift to the floor, and peered ahead.

There was light ahead—a lot of it. Even the gallery they were in was almost twilit now; he could see Doc Chimp, gasping ragged breaths beside him, the shoe-button eyes imploringly fixed on the light ahead. The rest of the Pur­chased People were worse off still, but, strangely, the one worst affected of all was the Sirian eye. The enamel globe of its orb was paled and tarnished as it sped past them to join the other aliens ahead.

If the creatures had been quarrelsome before, now they were frenzied. “Let’s take a peek,” Doc Chimp whispered hoarsely, and the two of them crept silently toward the head of the line.

And stopped in wonderment.

The gallery ended on a sort of a great, wide balcony, and the balcony looked down on a vast drusy cavern, with what seemed to be faceted diamonds and opals and rubies set into the metal walls. And what walls! They were immense! The cavern dropped sheerly a kilometer and more beneath them, extended at least four kilometers into the distance. And beyond it there were other, vaster chambers still. It was not easy to see very far, because the great chamber was crisscrossed with cables and mirror-bright rods. A thunder of something in motion filled their ears. The walls themselves glowed; the scene was as bright as an afternoon on a Polynesian beach, though there was no central source of light.

As Tupaia’s eyes became accustomed to the scale and brightness he realized that what he had thought were pre­cious stones were in facts discrete lights. Almost like in­strument lights on a panel; the whole scene, he thought, was like the interior of some vast machine, with its count­less thousands, perhaps millions of indicator lights and gauges.

Beside him Doc Chimp was panning his tachyon camera across the scene, muttering to himself. “Oh, Mr. Tupaia, this place gets worse and worse! What do you suppose that Watcher’s doing now?”

Tupaia said suspiciously, “Watcher? I don’t see the Watcher.”

“Not with those other creatures—down there! Way down there, between those two big pipes, don’t you see?”

The hideous creature was at least half a kilometer away from them, dipping and soaring among the great beams and cables on his leathery wings. He looked tiny at that distance, but the other creatures were near enough. The sounds of their quarreling rose to a crescendo, and Tupaia felt the chimp shiver beside him. “Oh, good heavens,” the animal moaned. “Do you see what that Sirian’s doing? That means something special’s going to happen now! And it’s bound to be something bad!”

The great eye was limping back toward them, its crackle of electrostatic force muted with fatigue and disarray. It paid no attention to the terrestrial creatures but made for a particular metal object, sharp-angled and with a sort of soft, folding cover over one face. With a crackle of force the Sirian thrust the cover aside and squeezed itself into the box; a moment later it emerged again and dragged it­self slowly back toward the other aliens.

“What did it do?” Tupaia demanded.

“It sent itself back!” Doc Chimp cried. “Don’t you know a tachyon chamber when you see one? It went in and got itself copied; and that copy’s back on the orbiter right now, stewing up heaven knows what sort of mischief.” He had followed the Sirian with his little camera, and now let it drop in exhaustion. “Oh, Mr. Tupaia,” he whimpered, “I wish I’d never come here.”

Tupaia turned his back on the sobbing ape, breathing heavily in the damp, copper-smelling heat.

What sort of place was this? It was not merely an arti­fact buried in the ground After all those untold kilometers, he had to believe that the entire crust of Cuckoo—this part of it anyway—was an artifact! Something, for some reason, had constructed it. This great chamber with all its lights and rods and roaring, muted sounds—it was like being in­side the control of some vast, automatic machine.

But for what purpose? And built by whom?

The Scorpian robot was welcoming the return of the Sirian with a drumroll of angry reproach—for what, Tu­paia could not guess. He could not hear individual sounds very well, would not have understood them if he could, for almost none of the Purchased People still had Pmals. The young man with the scarred face, almost the only one who had, was listening with that blank, opaque stare that meant some distant owner was occupying his mind.

Intent on the squabble, Tupaia brushed an annoying in­sect out of his face, and was astonished to find the thing so dense that it hurt his hand when he struck it. He had no time for such thoughts, though; Doc Chimp was moaning, “Oh, Mr. Tupaia, do you see what they’re doing? Do you know what that means?”

The Purchased Person with the Pmal, obeying some or­der, had bent to open a bale of equipment of some sort. Tupaia could not identify it; it seemed to contain folded— garments? No, not garments, but some sort of chest har­nesses, with blunt torpedo-shaped metal objects attached to them. “Thrusters!” Doc Chimp sobbed. His eyes were dull, his breathing labored, his demeanor hopeless, even as he was pointing his camera at the emerging equipment. “That means they’re going to make us put them on!”

Tupaia growled, “What’s wrong with that? Better than walking!”

The chimp shook his head miserably. “Not in that mor­tal long tunnel we just came through, not with all those bends and turns. But out there—out in that big cave— don’t you see? They’re going to make us fly straight through!”

Tupaia slapped another bug away and then, realizing what he had done, looked around. Why, the air was full of the bugs! Even in the semidarkness he could see dozens of them, hundreds.

And then he saw that there were swarms of the little insects, all over, even out on the balcony. The other Pur­chased People had noticed them now, and a sudden aston­ished rise in pitch of the gabble of the aliens said that they had discovered them, too. They were coming from the tachyon transporter. A bright bubble blossomed from the machine. It popped, and a batch of a thousand of the in­sects buzzed out of the chamber as he watched—and an­other batch—and another—it was like watching puffs of vapor from an antique steam engine, thousands upon thou­sands of them. For a mad moment Tupaia found himself a boy again, bringing breakfast to the tourists in the over- water dining room on Moor6a. To entertain the whiteskins he would throw a slice of toast into the water, and—oh!— what a frenzy! The water would boil with silvery bodies and gold and blue, flashing and flailing into each other like a tiny underwater game of pushball, until magically the last crumb was devoured; and just so these flashing bright crea­tures milled and raced around—

But were by no means so harmless.

Doc Chimp cried out in alarm. “The Boaty-Bits! I’ve never seen so many of them!”

And then, slowly, his voice shaking as if in mortal fear, “But they’re collective beings. It takes a thousand of them to equal a human or a Sheliak or any of those—that’s why they go in swarms—but here—” His voice failed him. “Here there’s a million or more,” he gasped, “and what will that make them equal to?”

Perhaps the Sheliak and the Scorpian had thought of the same thing; at least, their actions showed sudden panic. The robot whirled in midair and, steam jets screaming, raced toward the Purchased Person bearing a load of queer double-stocked weapons, while the Sheliak extended a lightning-fast tentacle in the same direction.

Fast as they were, they were not fast enough.

The milling swarm of Boaty-Bits seemed to shudder in midmotion. Then, with astonishing speed, the entire swarm coalesced around the Purchased Person. They swarmed onto him like African bees onto a luckless victim, covering him from head to toe with a solid, shimmering coat of steely blue. The Purchased Person staggered, then swiftly dropped to one knee, grasped the two-stocked weapon, and fired. The Scorpian robot exploded into a million shards of hot steel as the greenish blob of light struck; a moment later, with a sound like bacon frying, another green bolt in­cinerated the Sheliak.

“How—could he—” Doc Chimp muttered feverishly, and then answered his own question. “The Boaty-Bits took him over! And—heaven help us now, Mr. Tupaia—here comes the Watcher!”

Tupaia instinctively shrank back, as the Watcher screamed up from the depths of the cavern. Its hoarse, hooting roar was almost deafening, even above the thrum­ming in the immense pipes; great flapping wings brought its vile odor in a hot and nauseating gust as it lunged to­ward them—and past. It dropped to another part of the line, cawing its terrible rage at the two Purchased People staggering under the mass of the great translucent block. One fled. The other tried. Not fast enough. The foul talons ripped across his back and blood spurted. The Watcher dropped to the keyboard and its claws danced across it.

Yes. It was a weapon. That green glow formed over the block, elongating toward the Purchased Person wearing the cloak of Boaty-Bits.

The green charge grew and slid toward the edge of the block. Then it raced away. It struck the Purchased Person, and he ceased to exist. Half the Boaty-Bits got away, the rest simply disappeared. It went on.

It went out into the cavern.

Those shining rods, those delicate silver wires—they were in its path, and it touched them. A rumble like a distant H-bomb filled the cavern. Green fire flared into terrible brightness. Tupaia ducked his head, crouched to shield himself from searing heat. A scream from the Watcher faded into sudden dreadful silence. He heard the monkey whimper.

At last the wave of heat receded, and Tupaia lifted his head and tried to see. He could not. His stinging eyes found only a foggy red blur.

“My eyes!” he heard the monkey moaning. “I burnt my eyes!”

The Watcher howled again, in rage and fear, and then the shock wave hit them.

The blast battered Tupaia’s body, hurt his ears, dazed him. Dimly, through ringing ears, he heard the diminishing echoes that rumbled after it. When at last he could get his breath he picked himself up and stared around fiercely through the thinning blood-red mist. At least his vision was returning!

The curious mirror-bright rods were intact, but the sil­very cables were slowly wriggling themselves into cork­screw contortions, a great loose skein of chrome-colored spa­ghetti. Huge metal beams had been bent and torn, and somewhere a pipe containing liquid had burst. The plume of liquid dashed itself into spray—or perhaps it was steam, for the heat was indescribable.

Near him the monkey lay in a sobbing heap, hands over his scorched eyes. And the Watcher stood still at his terri­fying weapon.

If he had seemed mad before, now he was utterly ber­serk. He played the console of the weapon again, this time toward the bulk of the remaining group of slaves. They were vaporized at once; and the Boaty-Bits buzzed wildly above them.

Apart from the Watcher, Tupaia, and the chimp, the only individual creature still alive was the horse-headed Canopan, and his future suddenly was in doubt. The Boaty-Bits—more of them every minute, as the tachyon chamber spat out new swarms—wheeled and descended on him.

Screeching horribly, the Watcher lifted the weapon to­ward the shrouded figure of the Canopan—and stopped.

The Canopan raised its hand, and spoke—in a tone wholly unlike its usual whinnying tongue.

The effect on the Watcher was spectacular. It froze. It held motionlessly for a long moment.

Then it screamed in horror and outrage, heaved the great block away out over the balcony. It spun and turned as it fell slowly into the depths. The Watcher, shrieking its despair, turned and flew away.

Tupaia swallowed and glanced down at Doc Chimp. “What—what was that?” he demanded.

But there was no answer. The little chimpanzee was drooping slowly toward the floor, one long, skinny black hand trying vainly to press back the bright flood that spurted from a wound over his heart, the other pressed to the blinded shoe-button eyes. Some tiny fragment from the battle had found an unintended target.

And, except for that strange horse-headed figure with its mummy-wrapping of Boaty-Bits, Tupaia was alone.

He turned and ran back up the corridor, expecting at every moment to feel that bright green blast on his own back.

It did not happen; but the way to escape was not open. The gallery was shuddering under repeated explosions from the disasters in the cave, and as he rounded a turn he saw that some of those quakes had brought down the roof.

The tunnel was blocked.

There was no longer any way back to the surface.


And now I wake to desperate danger.

Unholy intruders are stumbling on HIS most precious secrets. They are violating the forbidden spaces, attempting to destroy HIS masterwork, in which HE lives, as HE must live forever.

There are urgent things to be done. Though the first clumsy desecrations have failed to end HIS eternal being, as all others in the past have failed, grave damage has been done. Graver danger still exists. I summon the clustered servants that cling to the inner shell and dispatch them to the scene. They are ready. They have rested and fed and grown fat in the flood of energy from the central source. For centuries of centuries of centuries they have been ready to protect and repair HIS everlasting body, and they are eager.

I trace the star-girdling rings for further damage and further danger. I find HIS great creation still supported by its shells of superatomic rings. No ring is broken. None must ever be, for there even HE is vulnerable.

I find no breaks. As yet the shell is safe.

The driving-mouths at the poles are safe. They continue to slow us for entrance into the new galaxy and they are ready to maneuver us when the time is here.

The billion clones are safe, in their liquid-helium baths.

I am safe, in spite of the intruders within my fabric, for they do not even know I exist.

And HE is yet safe.

I need not wake HIM yet. But soon.

Now I long for the moment of HIS awakening because

my fear of him is drowned in my dutiful concern for the eternal wonder of HIS plan. HE will end all danger when HIS holy moment comes. When every mind has surren­dered to HIM, even every parasite within HIS eternal being and every crawling thing in the galaxy ahead, none will remain free to profane HIS ultimate plan.

That time is near. And when it comes—

When it comes there will be no safety for anyone, any­where, except the ultimate terminal safety of surrender to HIM.


Down below them, Cuckoo’s huge weather engine was building up a great cyclonic storm. The engine ran on heat, as in every other astronomical body, but Cuckoo’s heat transport came from the inside to escape into space. Cuckoo’s storm had been growing for weeks, and it had its counterpart on the orbiter, a slow, vast vortex that swept beings Jen Babylon had never seen before in toward the center of the structure. That was where the huge com­puter farlink whispered to itself, surrounded by its banks of flat-picture screens and stereostage enclosures for holo­grams. In one stage the great virtual-image globe of Cuckoo itself turned slowly, most of its surface still blank or only vaguely sketched in from satellite reconnaissance; a few sections thick with detail of continents, mountains, seas. But the globe of Cuckoo was not the display the beings swarmed toward. That display came from Doc Chimp’s tachyon camera, far below the surface.

The stereostage images were terribly disturbing. They were also terribly poor in quality, for the chimpanzee’s hand-held camera caught only quick and fragmentary glimpses. But that was where farlink came in. Its power­ful circuits selected every bit of information, assayed it for validity, weighed it for importance, assigned it a place in a greater picture. It edited, interpreted, selected, so that its algorithms extracted maximum information from the most corrupt signal. The result was displayed in the central stereo­stage, while details were shown flat on any of the half- hundred circling screens. What the horde of beings saw was not a moving hologram but a series of stills—but it was enough. The entire orbiter was in a flap, as the vortex drew every living thing into that single room.

There was no calm in this storm’s eye. The great dome was bedlam. Shouts, screeches, roars; rataplan of Scorpian robots, neighing sobs of Canopans. Doc Chimp, tugging fretfully at the long green feather in his cap, dodged a dense cloud of Boaty-Bits and muttered to Jen Babylon, “It’s feeding time at the zoo!” His shoe-button eyes were fixed woefully on the image his other self was transmitting from so far away.

Babylon nodded, his face drawn. “Smells worse than any zoo I’ve been in,” he agreed absently, and was rewarded with a burnt-rubber smell of indignation as the T’Worlie that had hovered by his shoulder flounced away. He sighed, wincing as a Scorpian hissed past, drumming at the top of its timpani. His Pmal was overloaded; with every being trying to communicate at once its language matches were completely unable to keep up. What came to his ears was a jumble of words and phrases, and simple static.

For no one understood what was happening. That the expedition was traveling downward into the heart of Cuckoo was obvious; that they were passing through me­tallic tunnels, galleries, chambers was apparent. But what did it mean? Everyone—every being—had a theory. The Scorpians had discovered secret plans of the tunnel, leading to some incredible trove or treasure; the Scorpians denied it with fury. The Sheliaks were in league with the deltaforms to trigger tectonic forces and destroy Cuckoo entirely—the Sheliak nearest that theorizer nearly destroyed him in re­sponse. The Canopans accused the Sirians of having en­slaved their one representative in the expedition with an illegal Purchased People unit; the Sirians screeched that the facts were right, but the enslavement had gone the other way. No species accepted responsibility. Every one vowed that its conspecific was a rogue who had been act­ing oddly for some time. Was there truth in any of it? There was no way to be sure—and no way, really, to dis­cuss any of these things intelligently with the overloaded Pmals faltering in the incessant din.

And meanwhile Doc Chimp’s little camera recorded a journey that went down, down, down, toward no one could guess what.

Ben Pertin sailed through the whirlwind of beings to link arms with Babylon and bring himself to a stop. Babylon glanced around warily, then whispered: “Anything new?”

Pertin shook his head angrily. The one secret they had retained was the tachyon cap; in Pertin’s own chamber Zara was wearing it, trying to eavesdrop on the Purchased People in the expedition. “You can’t pick out the ones you want,” he complained, “and then when you do get one it doesn’t tell you anything.” He moodily watched the slow build-up of images on the stereostage and detail screens for a moment. “What we need,” he said, “is a Watcher. They know more than we do!”

Org Rider, hanging close by in the little group of Earth primates, shook his head. “There’s none on the orbiter now,” he said positively. “And that one”—he frowned at the stereostage—”is insane.” And indeed, the image looked very much that way; the hideous being had been captured in midflight, against a background of dull metal tunnel ceiling and walls, its horrid face screwed up in an expres­sion of rage and fear.

Emotions were running high everywhere, Jen Babylon thought. The crowd in the room was seething with anger, resentment, fear—and other, less guessable emotions, which had no clear counterpart in the human repertory. You could not tell what the Boaty-Bits, for instance, were feeling. Angry or overjoyed, they still danced in their dense swarm like flies in the light over a swimming pool on a summer’s eve. The TWorlie alone seemed unmoved. Noth­ing of smaller scope than galactic could touch their ancient feelings. They did not possess either fear or resentment in any personal sense; what they wanted of life was to learn and ponder, and all the revelations of secrets and conspir­acy provided for them was a set of new phenomena to study.

And perhaps the TWorlie were right. Babylon told him­self justly that the “enemy”—the rogue beings leading that expedition—had really done nothing that could not be ex­plained. Indeed, nothing for which an explanation was really required. They were exploring new ground. Well, given the chance, what being among them would not? There was no evidence to convict them of a crime. No crime had been committed. The most you could say against them was that they had acted in secret.

Yet in his heart Babylon knew that something was terri­bly wrong. The individual beings were rogues; the collec­tive purpose of the expedition was threatening.

And he was not alone in that feeling. Each in its own way, the seething mass of beings that hung by the walls, floated in midair, or flapped, clung to stanchions and each other—that raucous, malodorous congeries of nightmare shapes that were his shipmates—they all shared his fear, rage, and indignation. The Canopans had demanded a Grand Council. The T’Worlie had agreed, out of their own patient curiosity more than any desire to prosecute; and beings Babylon had never seen before, or even dreamed of, were still flocking to the great interior farlink chamber.

How they bellowed, and how they stank! The handful of true humans—loosely enough defined, to be sure, to in­clude Org Rider and Doc Chimp—huddled near the en­trance, trying not to be choked by the hot-iron stink of the Scorpian robots and the vinegar scent of the inquisitive T’Worlie, and the fouler reeks of the beings that looked like kittens, or roaches, or sea anemones or copper-wire mantises. There were beings here Babylon had never seen before: the anemone-creature, with its violet shell shading to dark purple, slithering eel-like shapes with tentacled eyes, a soft-bodied sort of beetle with many legs, a human form—but no! It was not human! It was a winged woman’s figure, but silvery and with blank, opaque eyes. “It’s an edited form,” Doc Chimp whispered nervously when Baby­lon asked. “Don’t be deceived by the way she looks! She’s not human, no, not a bit!” And before Babylon could ask more, she was lost to sight in the crush.

There had to be three hundred beings in the room! Not counting the Boaty-Bits, who were so thrust about and jos- tied by the crowd that they could not maintain the integrity of their swarm, but buzzed about like a smoked-out bee­hive. Doc Chimp, morose and distraught, flung himself into the mob to get a better look at the hologram, then wriggled his way out again. “Good fellow primates,” he said distractedly to Pertin and Babylon, “I can’t see a thing! And it’s me down there, and I tell them it’s my cam­era that’s sending them the stereopictures, and they push me out of the way!” Babylon gave no answer, because he could think of none to give. The chimpanzee wrinkled up his long black lips and muttered, “Here’s Redlaw, anyway. 1 forgot to tell you I saw him coming.”

Pertin spun eagerly around. “Anything?” he demanded. The big man looked around carefully before replying.

“Not the way you mean,” he said, loud enough to be audible above the din, too low for his words to carry be­yond the small group. “But there’s something, all right. Your girlfriend, Benpertin.”

“Doris?” Pertin scowled sourly. “What can there be about her that would be important?” He caught a glimpse of Babyon’s expression and added, “Oh, come on, she’s just a convenience—I don’t care if she lives or dies! Why should I? And don’t look at me that way—do you know how she got to be a Purchased Person? Torched the house where her husband and three babies were sleeping! Killed them all! You think I really care about someone—”

Redlaw put his hand on the other man’s arm, his expres­sion showing that his feelings were no more kindly than Babvlon’s. “It isn’t exactly Doris,” he said softly. “It’s the creature that owns Doris who has something to say. You’d better hear it, all of you.”

Doc Chimp muttered, “But the Grand Council, Mr. Redlaw! It’s supposed to start any minute—”

Redlaw’s deep growl cut him off. “The council doesn’t know what this is all about. Come! And bring that T’Wor­lie if you can find him.”

As almost the oldest resident of Cuckoo Station, Ben Pertin had certain privileges. One was the room he slept in.

It was a faceted polyhedral chamber, most of the interior faces filled with flat pictures of scenes from his lives. Past the stereostage was an exterior shot of Sun One. Over his bed loomed the immense majesty of Knife-in-the-Sky Mountain. In the center of the room, fitted with soft bind­ing tapes to keep an occupant from floating away in his sleep, was Pertin’s bed; and as they entered someone lifted a head from it to gaze at them.

From the side of the room Zara came toward them, the helmet slung from one hand. Her expression was strained. All she said was, “I’m glad you’re here.”

Ben Pertin—Babylon could not decide whether his voice was surly or embarrassed—scowled at the bed. “Doris giv­ing you any trouble?” he demanded.

“It’s not Doris,” said Zara, and from the lips of the fig­ure on the bed a woman’s voice, unearthly slow and care­fully formed, said:

“Attend the person Zara. This person has already com­municated.” And the woman turned her face to the covers of the bed, waiting.

Doc Chimp turned his leathery face to Zara. “And what does that mean?” he asked plaintively.

“She’s been telling me things,” Zara said. The strain on her face had not eased; the sound of her voice was trou­bled. “She won’t tell me much about her home planet. Least of all, where it is. But it’s hot. I believe in her real body—that is, its real body, the body of the thing that bought Doris—molten sulfur flows in its veins instead of watery blood. But they have a civilization not too much unlike ours: that is, it’s a collection of individuals, not a single multicellular society like the Boaty-Bits. And they differ widely among themselves—like us—not like, say, the T’Worlie or the Sheliaks.”

Mimmie, hanging inconspicuously by the doorway, danced gently forward. “Disagreement,” he chirped. “TWorlie find other TWorlie quite individual.”

“I know,” Zara agreed, “but you’re more, well, united than human beings, aren’t you? Anyway. The important thing is, some of their individuals on this fire planet are doing the same sorts of things humans are on Earth. It’s their equivalent of Kooks.”

The female human figure on the bed stirred restlessly. It did not lift its head, but the unearthly voice, muffled by the bedclothes, said: “Speak of zero-mass tachyons.”

Doc Chimp exploded, “That was private information! Good heavens, Ben! I didn’t know Homo sapiens primates could be so naive! Didn’t you know better than to discuss that sort of thing with your fancy woman, knowing she was Purchased?”

Pertin said defensively, “I didn’t! Tell them, Doris—I mean, you there, whoever you are!” But Zara interrupted.

“Ben is right,” she said. “The … being wasn’t repeat­ing what she had heard from us. She was telling a deep secret of her own race.” The figure on the bed moved con­vulsively, but was silent. “They have used zero-mass tach­yons for their own purposes for a long time, but have never shared the knowledge with the rest of the galaxy. And they suspect that their … Kooks are controlled with zero- mass tachyons from somewhere else.” She took a deep breath. “They think it’s from Cuckoo,” she finished. “And they think that the members of the expedition are con­trolled in the same way, or at least their leaders are.”

The figure lifted its head. “These are instructions,” it said tonelessly. “Display spherical object. Consider relation­ships. Advise all other beings.” And the woman’s figure tossed away the restraining straps, rose from the bed, and moved silently out of the chamber and away.

Babylon saw the strange, almost fearful look on Pertin’s face as his gaze followed her, and understood something of what was in Pertin’s mind. “Consider relationships,” in­deed! Babylon knew what relationships his friend was con­sidering. Doris was a Purchased Person, whose distant owners were only academically interested in human sexual practices. Usually she was permitted to share Pertin’s bed only when they had no other plans for her. But sometimes they were in direct control. How strange it must be, Baby­lon thought, to murmur drowsy endearments into a worn- an’s ear, and find a reply from her remote and inhuman owners!

But there was not much time for such reflections now. The TWorlie moved silently to the center of the room, fac­ing its human companions. It chirped, “Concurrence. Rec­ommendation to advise all other beings is agreed.” It floated silently for a moment, its five eyes seeming to stare at each of them in turn, then added a quick series of chirp­ing whistles and a pungent smell of clove. The Pmals rapped out the translation: “Observation: Situation becom­ing critical. Proposal: All information now be shared, in­cluding data from helmet, information store obtained from wrecked vessel—and communication just received through being identified as Doris.”

Redlaw boomed, “He’s right! We don’t have a choice— so let’s do it!”

If the orbiter had been excited before, now it was like an anthill gone mad. Beings of every fantastic shape flew and hurled themselves along the corridors. The news had sped faster than a tachyon transmission, and each race, almost each individual of every race, reacted with its own special pattern of consternation and anger, and even fear. Hardly a civilized planet in the Galaxy, it now seemed, had been spared its equivalent of the Kooks; and the suggestion that they were all part of some incredible conspiracy was explo­sive. Chugging Scorpian robots sped through swarms of milling Boaty-Bits without warning; Sheliaks and Pur­chased People stopped each other at the intersections with furious bursts of screeches and rattles from the overworked Pmals; and all of them tried to crowd their way into the farlink chamber, where the T’Worlie were feeding data into the computer as fast as it could be accepted.

First Babylon had overseen three great Sheliaks, func­tioning as porters, as they bodily moved the store of hexa­gonal rods and their reader into the chamber. Then they obeyed the Doris-being’s command.

The TWorlie had plugged farlink into the circuits, and every datum from the hexagonal rods was entering its data stores. The images were slower to build, but they were clearer, more detailed—farlink was not only observing, it was pondering what it saw, matching it against a vast store of information. Doc Chimp was given the task of feeding the hexagons into the reader; he fumbled through the stack until he found the key one—the “spherical object”—and slipped it into its slot.

At once the translucent block cleared, and the great metal bubble shone forth inside it. Doc touched the scan­ning plate, and the image began to go through its cycle— slowly now, as farlink studied each new display in turn and enhanced the images. First the featureless metal globe. Then the cutaway sections. Then the schematics: a net­work of scarlet structural members, replaced by an inter­linked system of ivory-colored arteries—transportation pas­sages? Something like that, perhaps. Then, coded in bright silver, a set of mirror-finished rings, making a sort of bas- ketwork duplicate of the sphere itself.

The swarm of beings in the chamber hissed and mut­tered to each other, but no clear voice emerged. Doc Chimp pushed himself back and stared morosely at the im­age. “I don’t see anything sensible,” he complained. “What’s it supposed to mean?”

Zara said doubtfully, “Well, let’s see. It’s a sphere. An artifact. I suppose it represents some instrument or ma­chine—a spacecraft, maybe?”

Babylon ventured, “I understand there are old orbiting vessels you can’t approach around Cuckoo—like the wrecked ship?”

Pertin shook his head. “They don’t look a bit like that,” he growled, and then called, “farlink? Any interpreta­tions?”

The clear, cold voice of the machine replied, “Negative. Analysis continuing. More data required.”

The humans looked at each other, and Zara shrugged. “The helmet?”

Org Rider nodded. “We have no choice,” he declared. “Benpertin, please produce the helmet. We must share this information, too!”

* * *

The excitement and resentment that followed the giving up of the helmet—how dare these Earth beings withhold valuable data!—was only exceeded by the uncertainty of how to use it. Obviously the helmet could not be worn by farlink as it could by a human being—or by the beings who had made it; obviously, if those who had worn it sim­ply told farlink what they had seen they would omit much priceless data, or corrupt it. At last a Sheliak plunged into the center of the group and plastered itself against farlink’s data-input terminals, extruding a bubble of its flesh toward the helmet. The bubble crept inside; the doughy mass of Sheliak flesh suddenly contorted, and then was still. Pertin nodded grudgingly. “Knew the damn beasts would be good for something one day,” he declared. “They can shift their organs and nerves around as easily as their bodies—it’s giving direct transmission of its nervous impulses to the computer!”

Babylon shook his head unbelievingly. “Raw sensory in­puts? How can farlink read them?”

“That’s farlink’s problem, and it’ll solve it,” Pertin boasted. “Just wait and see!”

It was easy enough advice to follow—there was no real alternative!—but the mob of beings in the chamber was getting louder and more raucous.

The first sign that anything happened was that the great globe from the hexagon-rod data disappeared. The cube re­mained clear, but it contained no information. There was a gasp, buzz, hiss, whistle—whatever sounds each made— from the beings; but as moments passed and the image did not reappear the surprise reverted to angry impatience.

Then, at a single stroke, all the dozens of circling flat- picture screens were wiped blank, while the holo of the expedition on the center stereostage firmed up. It became more clear in all its parts, and began to move in real time. farlink was doing its job. As it matched the images from the other Doc Chimp’s camera against the data from the helmets—and against that vast collection of other informa­tion that made its datastore—it filled in the gaps, interpo­lated details, made the scene as real as if the observers were standing at some vantage point and beholding the scene itself.

Since there was nothing else to look at at the moment, every being in the chamber was looking at the scene, and one, at least, felt a queer stirring, half a memory, half a long-forgotten apprehension. Jen Babylon shook his head. What was it? The scene showed the toiling line of porters and leaders passing through the narrow corridors and emerging into a great chamber, kilometers wide and deep, with walls that seemed to be set with bright, winking jewels and a network of cables and branching cyclopean struc­tural beams. All rose from a floor formed of silver-white lines that looked thinner than threads, too fragile and too far apart to hold anything.

“I’ve seen that before,” he muttered, mostly to himself, but beside him Zara caught the words and looked at him curiously.

“You have, Jen? Where?”

He shook his head. “I can’t remember,” he confessed. “Maybe in a dream. Quite a while ago. —No, it’s gone. But somehow that looks familiar—and frightening!”

She studied his face carefully before she said, “Please think hard, Jen. It may be important.”

And perhaps it was, but Babylon got no chance to think about it more carefully, nor did any being in the chamber, about that or about anything else. For the blank cube sud­denly sprang into life. It showed the ball of layered silver rings, then the ivory arteries, then the bright scarlet struc­tural members—the same sequence as before, but in re­verse order, as if the artifact was being constructed before their eyes. And much faster, much surer; with a sense of reality and solidity to the images that had been lacking be­fore. Like the first series, the remaining view was the great featureless globe, hanging in space.

But it did not stop there.

The globe clouded over. It showed markings that looked like a satellite’s view of a distant planet. First mountains and wide, shallow basins. Then the basins were filled with seas and lakes, and tiny spiderweb lines on the surface filled with liquid to become streams and rivers. The moun­tains sprouted forests; the lowlands were lush with vegeta­tion or bleak with scarred rock and desert sands. At last the atmosphere began to fill with clouds, all sorts of clouds—glowing clouds in a thousand hues in one place, fleecy cumulus and towering cumulonimbus in others, and in one huge patch, covering nearly a tenth of the surface of the globe, a great swirling cyclonic mass.

A great, involuntary sound went up from the crowd star­ing at the display, then a loud, excited buzz. “It’s Cuckoo!” cried Org Rider. “That’s the big storm that’s been develop­ing for weeks now!”

And Ben Pertin laughed queerly. “You’re right,” he said, half sobbing, “it’s Cuckoo. The artifact is Cuckoo. Cuckoo is an artifact. It’s not a planet—or a star—or a mere astrophysical anomaly. It’s a machine!”

A machine! It was unbelievable—and yet farlink was registering .999-plus certainty, and all around the chamber the flat screens were lighting up, one by one, showing de­tails of the mechanism, cyclopean Cuckoo-girdling bands, great chambers with cryptic contents, vents, and thrust- mountings—it was an engineering plan of some immense edifice, no doubt of that! The hubbub grew to a crescendo, and then there was a silvery chime, farlink wished to speak. Its flat mechanical voice tolled, picked up and translated by a hundred Pmals into a hundred different tongues:

“Analysis complete! Object has been tentatively identi­fied as a Dyson sphere, conjectural astrophysical artifact proposed by Freeman J. Dyson, planet Earth, mid-twentieth century. Dyson suggested that a truly advanced race of technological beings, using ever-increasing amounts of energy, would ultimately devise a scheme to capture the entire energy output of its parent sun by surrounding it with a sphere of matter produced by rearranging the non- stellar components of its solar system—planets, asteroids, comets, satellites, dust and gas clouds, etc.—into a shell, so that no radiant energy could escape the system without being made to do work. Signatures. Dyson proposed that a telescopic search be made for large, light objects radiating faindy in the infrared. No large-scale systematic search was made, and the proposal was forgotten. However, Object Lambda, a.k.a. Cuckoo, possesses these signatures. Details. Reference display one.” One of the flat panels was sud­denly surrounded by a halo of flashing color; it displayed the basketwork sphere of layered rings that had already been seen in the records of the wrecked orbiter. “Surface sphere is clearly supported by ring network. Hypothesis: Each ring consists of matter moving at more than orbital velocity, thus generating centrifugal force that keeps the shell from collapsing into the central sun. This high- velocity motion is evidently essentially frictionless. Exact nature of rings and means of their control at present not known. Reference display two.” A tiny, incredibly bright spark of light, surrounded by cloudy glow. “This is the cen­tral sun, identified as a type F-4, now in an atmosphere of relatively dense plasma extending to the inner surface of the shell. Reference display three.” An interior view of the shell, with some sort of tiny objects in slow motion within it. “These are apparent self-reproducing mechanisms, ab­sorbing energy from the star and storing it for purposes not yet established. Reference display four …”

But Babylon could look no more. The fourth screen was showing the openings in Cuckoo’s poles. High-rimmed holes, each tens of thousands of kilometers across. Nozzles! Thrusters for plasma jets that drove and controlled the in­credible structure . , . but he had absorbed all he could, and he returned to the central marvel.

A Dyson sphere! Now he remembered. It had been in an early astronomy course, before he had settled on his major in linguistics. The instructor had joked about it. Now that communication between scores of alien races was a fact, he said, it was clear that the so-called “Dyson sphere” was simply the ludicrous fantasy of someone who had read too much space fiction as a boy.

Babylon grinned to himself. “If only my old teacher were still alive,” he muttered, “this would kill him for sure!”

The TWorlie that had been hovering unnoticed by his head emitted a cinnamon odor of perplexity. “Query: Ref­erent not understood.”

Babylon shook his head. “It doesn’t matter.” And then, wonderingly, “A Dyson sphere! But—out here, in the mid­dle of nowhere? Where could it have come from?”

The TWorlie danced silently for a moment, then of­fered: “Statement: Representation of galaxy in temple not our own. Conjecture: Home galaxy of artifact builder?”

Babylon stared at him without replying.

Another galaxy? But the nearest other galaxies—the Magellanic Clouds and the Mafei 1 and 2—they were tens of thousands of light-years away. The nearest really big one, M-31 in Andromeda, two million light-years!

He felt his flesh crawling. Who would create an artifact as immense as Cuckoo and send it hurtling through inter- galactic space on a voyage whose duration could not be less than hundreds of thousands of years?

And why?

TWorlie twittering and a sudden reek of new paint caught him: “Reservation,” the TWorlie chirped. “Hy­pothesis of structure surrounding sun difficult to accept. First demurrer: No known form of matter possesses the characteristics required for construction of hypothetical frictionless rings. Second—”

“No,” Babylon interrupted, “but then no known object like Cuckoo exists, either!”

The TWorlie chirped on, disregarding him: “Second de­murrer: Position of stellar object at center of such hypo­thetical shell would be metastable. Inevitable small random displacements from central position would be accelerated by positive gravitational feedback.”

Babylon shook his head rebelliously. “Cuckoo exists!”

“Laws of physics also exist,” the TWorlie twittered, and an odor of overripe muskmelon accentuated the words. “Axiom: Laws of physics apply equally throughout the Universe and may not be denied.”

Ben Pertin cut in roughly, “What’s the use of this argu­ing? You’re just saying that what we can see to be true can’t be true!”

“Negative,” the TWorlie responded. “Correct interpreta­tion: To reconcile known physical facts with hypotheses regarding Cuckoo requires two corollaries.” The T’Worlie danced thoughtfully for a moment, as if it hesitated to say what it must say. A diffident, wondering scent of lilac em­anated from it and, although no human could read expres­sion in a T’Worlie’s tiny eyes, Babylon felt a stab of appre­hension at what was coming next.

“Corollary one,” the T’Worlie chirped firmly. “Design and construction of ‘Dyson sphere’ system required techno­logical and scientific skill at levels not now attained by any galactic race. Corollary two: Sphere was constructed, and at present is still controlled, by existing intelligence.”

The TWorlie’s chirping, and the rattle of the Pmals, lin­gered in the vast chamber and died away into silence.

And then the noise came. For long minutes the swarm of beings had been quiet, hanging on the farlink data and the T’Worlie’s observations; but they could be silent no longer. Buzzes, shrieks, whistles, brays—every being was speaking at once.

An existing intelligence! Something that had somehow survived the journey of endless years!

Babylon shouted into the din: “Do you mean that this object has a mindV

“Perhaps many minds,” the TWorlie chirped somberly, and added, “It must be so.”

Babylon turned away, unseeing. Cuckoo as an artifact was hard enough to believe—but to add to that the belief that somehow a guiding intelligence survived within it …

His imagination reeled. Only dimly did he sense that some new sound had been added to the noise. Doc Chimp snaked out a long paw and dragged Babylon to his side. The chimp’s sad face had suddenly become more woebe­gone than ever as he stared, with the others, at the forgot­ten scene from the camera of his other self, far below. It had changed. There was no resting on the part of the slave procession now; all of them were up and moving, and the expression on the chimp who grasped his arm was mirrored in the one down below the shell of Cuckoo. “It’s the Watcher,” Doc Chimp moaned. “He’s really gone mad now—and I’m down there with him.”

“Pull yourself together, Doc,” Ben Pertin snarled over his shoulder. “It’s just a copy!”

“It’s me,” the chimp insisted. “And they’re fighting, and—oh! Look at the Canopan!”

By now the entire chamber was watching the new chal­lenge to their sanity. Everyone saw the Canopan suddenly covered with a swarm of Boaty-Bits, the wild scuffling, the insane flight of the Watcher, the terrible destruction of the green-glow weapon.

“They’re trying to break it up!” Zara cried, as the green- glowing charge hurtled down toward the grating of slender silver rods that hung beneath the jungle of cables and branching structural beams. Babylon’s breath caught. Those wire-thin rods were the rings that supported the sphere. If they were broken, the whole surface here would cave, falling toward the central sun—

Or something worse! If the frictionless motion of the un­known stuff of the rings was really more than orbital, any broken ring would mean faster and more dreadful disaster. No longer frictionless, its unknown stuff would tear into the fabric of Cuckoo at velocities that must be hundreds of kilometers a second. Everything it struck would be ex­ploded into incandescent plasma. Including, probably, other rings in its path. Shuddering with something between awe and terror, he imagined all Cuckoo turning into a super­nova.

How many of the supernovas in far-off galaxies, Ben Pertin wondered, were signals of advanced intelligence and ultimate technology snuffed out by catastrophic accident?

Not breathing, he watched the green-shining missile strike the silver rod. It exploded. The whole screen burned with green fire and went abruptly black. The camera had been overloaded.

“They’re trying to kill Cuckoo,” he tried to say. “Trying to kill us—”

He had no voice. Around him there was silence, then a muffled stir of breath and motion. He tensed in spite of himself, waiting for the final crash of sound, for the walls to buckle around him and the whole world to dissolve into fire …

It couldn’t happen that fast, of course. Cuckoo was too huge. Even a plasma explosion would take time to swallow it all, more time to reach the orbiter.

The screen lit, dimly at first, then with more brightness and clarity. Babylon could breathe again.

“Nobody,” Doc Chimp whispered, “nothing could live in that!”

And it seemed true. They could see the cavern again. Apart from the Watcher there seemed no one, no being, alive within the range of the camera, except for a huge man with skin the color of weathered brass, and the other Doc Chimp—and the chimpanzee was blinded.

Even in the stereostage the sight was fearful. The view­ers shrank away from the flare of green light that turned their faces queerly metallic. Ben Pertin laughed—hysteria, Babylon thought; but Doc Chimp took it personally.

“How can you?” he chattered furiously. “I thought you were my friend! If it was you down there—”

“If it was me,” Pertin said brutally, “it would come to the same thing. So you’re being killed! But we’ve both been killed so often already it just doesn’t seem important any­more. It’s the Boaty-Bits! They’ve been up to something all along. They have a lot of explaining to do—”

His voice broke off. His eyes darted around the room, and his face assumed an expression of comical surprise.

“What’s the matter, Ben?” Babylon asked.

“The Boaty-Bits. Don’t you see? There’s not one of them in this chamber—they’ve sneaked away!”

At least the noise level had dropped! It was not that the beings on the orbiter were calmer—quite the reverse—but now they were dispersed, as Scorpians and TWorlie, hu­mans and deltaforms, every being of every race joined in the orbiter-wide hunt. Where were the Boaty-Bits?

Within a few moments Babylon had lost track of the other human beings—Pertin in one direction, Zara in an­other, Org Rider and Redlaw heading for the landers on the assumption that the collective creatures were trying an escape. He and Doc Chimp were flying down a corridor on the trail of a mixed mob of Purchased People and Sheliaks. It taxed all of Babylon’s strength, but the chimpanzee was crooning to himself as he pulled them along the hoist-ropes with his powerful simian arms. “Died down there,” he sobbed, half to himself, “going to die again! Oh, heaven help this poor old monkey in this terrible world—”

Babylon, panting, tried to reassure him: “But that’s not true, Doc,” he gasped. “You don’t have to die again! Everything’s changed now, don’t you see?”

The chimp reached out with one long, black-furred arm and brought them to a jolting stop. “Changed?” he de­manded, peering into Babylon’s face. “You haven’t been here very long, have you? Nothing changes! You just go on dying and dying! It’s a pity us monkeys don’t get manic depressive, because this is a great place for suicidal types— you get so many chances to act it out! I tell you, they’re just going to decide to send down another party through the tachyon transfer, and somebody’s sure to say let’s take old Doc along, and—”

He stopped in midbreath. “Oh, Dr. Babylon!” he whis­pered softly. “The tachyon chamber. Of course! Come on!”

And, of course, he was right. In less than five minutes they were at the entrance to the tachyon-transport room, a long gaggle of beings trailing them in response to Doc Chimp’s agitated yells, and at the door the chimpanzee brought them to a sharp stop. “There you are!” he whis­pered triumphantly. “You see?”

And, sure enough, there inside the chamber was a Sirian eye—perhaps the same renegade who had transported him­self up from the catacombs—surrounded by a furious swarm of the steel-blue collective creatures. “What are they doing?” Babylon demanded.

“Can’t tell,” the chimp whispered, “but it looks as if they’re pulling Purchased-People units out of the store. Only they’re not here—”

But there was no more time for speculation; the rest of the lynch mob had caught up with them, and all beings together stormed into the chamber.

Jen Babylon had never seen one sentient being murder another before, but he saw it happen now. There was no stopping the furious mob. The Canopan was the first to die, and as he was struck down, bleeding a pumpkin-yellow ichor, the great equine skull crushed by a blow from a Scorpian, two Boaty-Bits flew out of the fleshy ruff that was its mane. They tried to join the rest of their swarm, but the swarm itself was disorganized, dying bit by bit as each one of them was struck by Sheliak tentacle, Sirian electric bolt or fist, hoof, horn, or whatever other striking appendage any being had. They died in the hundreds, si­lently at first. Then they swarmed together for a moment and buzzed fiercely, a screaming drone that the Pmals ren­dered as:

“Fools! You are doomed! Only collective intelligence will survive—and you will be part of it!”

And then they said nothing more. Not enough of them were left to make an articulate entity, and then there were none of them alive at all.

In Jen Babylon’s mind there was room for just so many wonders, so long a list of concerns. His senses were satu­rated and his mind full; and yet something new was clam­oring for attention. It took him a long moment to realize what it was.

The TWorlie lay huddled and broken in a corner. Its wings fluttered feebly, and it exuded a sour, sick reek that grated on Babylon’s senses.

“What’s the matter?” he demanded, reaching out to the sad little shape. It drew away from his touch, and the odor changed to something like a wet seabeach back on Earth. Babylon looked up to Ben Pertin. “Something’s wrong with the TWorlie,” he said.

The creature chirped feebly—more the rustle of a dying cricket than its normal bright sound. The Pmals did not respond at all. “He’s in bad shape,” Pertin said, his face drawn. “I’ve seen it before. TWorlie aren’t built for this sort of thing.”

Babylon shook his head in puzzlement. “There was a lot of commotion,” he said, “but I didn’t see him get hurt.” He stretched out a hand again, and the little creature shud­dered.

“Correction,” it chirped faintly. “Not hurt. Harmed.”

Babylon nodded, thinking he had understood. “Well, hadn’t we better get it to medical assistance?” he de­manded, staring around the chamber. Most of the nonhu- man beings were gone now, and only Pertin, Babylon, and the TWorlie were left in the great chamber.

But the TWorlie fluttered away. “Negative,” it stated. “Harm not physical. Healing required not medical.”

Pertin put his hand on Babylon’s arm. “I told you,” he snapped. “They can’t handle this sort of violence, intelli­gent beings destroying one another—”

“I didn’t care much for it myself!”

“No. Neither did I. But you and I can survive it, Jen, and I’m not sure Mimmie can.” Pertin bent to look more closely at the little batlike being, and the T’Worlie spoke:

“Further correction. Can survive. Have been harmed most gravely. Require therapy.”

“Therapy?” Pertin gazed up at Babylon and shook his head to show that he did not know any more than Babylon.

“Confirmation: therapy. Specific techniques necessary: healing constructive analysis and synthesis.” The T’Worlie raised itself gently on filmy wings, as if it did not dare put too much strain on them. “Statement: Depart now for ther­apy. Will return.”

The orbiter had become quieter, though wandering bands of beings still roamed its corridors, and Babylon had actually drifted off to sleep for a few moments when the TWorlie returned. It seemed much more energetic and strong, and responded to Babylon’s queries with confi­dence.

“Have completed therapy,” it stated. “Data developed is of value.”

“What data?” Babylon demanded, and listened while the TWorlie explained what it had done.

And that was nothing more or less than to reason out the explanations of many of the mysteries that had perplexed them: The creature had locked itself in with farlink, seeking escape from the pain of seeing life violated on such a catastrophic scale. And it had come away with what it called a healing hypothesis.

“And what is that?” Babylon demanded.

“Hypothesis: Rings are monatomic structures, e.g., sin­gle atoms.”

“Single atoms?” Babylon repeated, not comprehending.

“Confirmation. Data examined include reported exami­nations of individual rings and summarized results from all attempted investigations.

“Physical nature of rings has been unknown and per­plexing. Observed sections are extremely thin horizontal rods supporting the entire surface structure of Cuckoo. These rods appear mirror-bright, reflecting all incident ra­diation unchanged. They are frictionless in motion and ab­solutely hard, unaffected in any observable way by applied forces. They are reported to be magnetic and superconduct­ing—power required for the operation of Cuckoo is be­lieved to be transmitted through them. No natural sub­stance possesses such qualities, and the nature of the rings has remained a riddle, even to farlink.”

“But you’ve solved the riddle?”

“Hypothesis: Rings are atoms—”

“Isn’t everything?”

“Question irrelevant until you know hypothesis.” A sharp ammonia scent reproved him. “Convergent evidence suggests high probability that each ring is a single atom. The nucleus is not a point but a phenomenon—”

But Babylon could not let him finish. “Did you say a single atom? That’s ridiculous. Impossible! There must be something wrong with my Pmal.”

“Negative. Translation accurate. Term ‘single atom’ cor­rect.”

“But it can’t be!”

A whiff of orange-blossom amusement, fading fast as the still weak T’Worlie whispered, “Correction: Possibility exists. Evidence supports probability. Nucleus not a point but may be described as a phenomenon previously un­known. Term proposed for this is ‘nuclear polymer.’ De­scription: a chain of bound quarks maintaining a positive charge that hold a thick electronic sheath surrounding the chain. Such object would be friction-free and indefinitely strong, thus satisfying requirements observed.”

Babylon’s mind was spinning. He was no physicist, but he knew enough to be shocked at the notion of an atom of stellar size. “Is that possible, Mimmie?”

“Datum: The rings exist. Alternative hypotheses cannot account for them.”

“But—” Babylon shook his head, trying to imagine a single atom stretched into a ring capable of orbiting a star. “But what’s it made of?”

“Atomic structure of source material irrelevant to hy­pothesis. Possibly iron, which is a massive and strongly magnetic element, relatively common.”

“How—” He blinked. “How could such things be made?”

“Hypothesis presents few clues. The process of creation must have required enormous mass, enormous energies, and the use of technologies ultimately advanced. Probably not explicable in context of known physics.”

The T’Worlie fluttered suddenly closer, and he heard shouting and hissing and hooting in the corridor behind him as a last random fragment of the mob straggled across it.

“Forgive me.” A whiff of something like ether. “My ethical trauma not yet entirely healed. I require additional intellectual therapy.”

It was fluttering away.

“Mimmie, wait!” Babylon hushed his voice. “If you don’t realize it, your life’s in danger. I think you’ve really cracked the riddle of Cuckoo. You’ve got the secret we all came for. A precious secret, if you don’t know that—which places you in more than merely mental danger. People— things—will kill you for it, if you aren’t very careful.”

“You misunderstand the nature of my psychic trauma if you term it merely mental.” An ammoniac tang. “You should know that physical danger and physical death have never mattered to my people.”

Yet it came back a little toward him.

“If you don’t like violence,” he muttered, “remember those plotters. Trying to blow up all Cuckoo!”

“If my hypothesis is valid, such plots can be forgotten.” Its chirp seemed almost cheerful. “Known evidence indi­cates numerous past attempts to damage or destroy ring structure, which have always failed. Hypothesis suggests they will always fail.”

“If the rings are atoms—” He frowned, trying to grasp that novel reality. “Some atoms aren’t stable.”

“Ring stability abundantly proven.” The TWorlie flitted closer, with a scent like hot asphalt. “Cuckoo is supported by several billion rings that have functioned for many mil­lion years with no evidence of any breakdown.”

“Suppose the ring system collided with something?”

“Experiment untried. Hypothesis suggests rings might survive stresses even more extreme. If ring cores do consist of quarks arrayed in linear chain, protected by dense elec­tronic sheath, known physics indicates that it would be lit­erally unbreakable.” A breath of oleander. “Superstructures supported by ring system, however, would not survive ex­periment.”

“Literally?” He stared. “You mean to say the rings themselves can’t be destroyed?”

“Conclusion unwarranted. Hypothesis implies that rings are vulnerable.”

“To what?”

“To intelligent application of the same advanced science by which they were created. They are artifacts. Process of creation, however unknown, is irrelevant to hypothesis. In common experience, many processes can be reversed.” With a burnt-toast scent of apology, it was gliding away.

“Care, Mimmie,” he whispered after it. “Better not trust anybody. Your hypothesis could be true, but it could also get you killed. Maybe all of us.”


Te’ehala Tupaia, paramount king-warrior of the forces of Free Polynesia, stumbled out of the tachyon-transmission chamber with his eyes downcast and his step shambling, carrying on the masquerade of a Purchased Person— Into what?

He shouted in sudden rage and fear. Polynesian theology had no hell, but the missionaries had told him about theirs. Heat, noise, pain, bewilderment—had they been right? Was he in it?

Tupaia had no way of saying that this tachyon transfer was any worse than the earlier ones, for he had no memory that there had been any earlier; but he knew that this expe­rience was gut-knottingly, mind-wrenchingly terrible. Everything was wrongl Even the man in front of him was wrong—was no longer the same man he had followed in the prisoners’ file. Was no longer a human being at all! Tupaia stumbled in the queerly lit gravity of this awful place and crashed into him—or into it. Certainly this could not be a person! It was something queer, hideous, red-lit. It was a troubled dreamlike memory from childhood, for in the whiteskins’ preprimary school there had been fairy-tale books, with goblins and elves. One of tiny Te’ehala’s first shocks of betrayal had come when he learned that these creatures were lies. No such beings had ever existed—

But they did, and he was surrounded by them! The man ahead of him was now wearing the exact shape of a ko- bold—gnarly limbs, squat frame, craggy face. It was the most horrid creature Tupaia had ever seen, worse by far than the scuttling or writhing creatures at the bottom of his home lagoon, worse than a nightmare, for it bore human features. It turned toward him, and the eyes were the eyes of a person as vulnerable as Tupaia himself to shock and pain, as filled with terror; it spoke, and the voice was the voice of a human being, bleating for help. It was a diaboli­cal mixture of monster and man …

And so was Te’ehala Tupaia.

For he himself had been changed in the same way.

In that moment Tupaia nearly went mad.

He could find nothing familiar, nothing that related to any previous part of his existence. He was in a gnome’s body, inhabiting a devil’s cavern, surrounded by creatures queerer than any demons. He was seeing by a light that was redder than red—it stood in the same relation to red that indigo does to blue—and it had no source. He was on a balcony of sorts, and far below him was a tangle of ma­chines and pipes, with queer figures scuttling around and over them. And he was surrounded by a sea of raucous sound, like the middle of an April typhoon, but deeper and slower. The other Purchased People, as shocked and mad­dened as himself, were milling around in disarray.

Then, above all the tumult, came a call in a crackly, raspy sort of language that, incredibly, Tupaia understood. “Purchased People!” it grated. “You have been selected for labor in edited form for purposes of scientific research!”

The creature speaking was more hideous than Tupaia itself; it was a thing like a great blood-red eye, glittering like a ruby, that hung above them. The enslaved kobolds fell silent and it continued: “Reimbursement will be made to your owners. You have been edited in a stress-resistant form capable of functioning readily in this environment, and given optical systems capable of seeing by the heat sources all around us, with language faculties adequate to understand our orders. You need no more!”

It paused, and crackling tendrils of electrostatic force leaped from its ruby surface to sting Tupaia and some of the nearest others. “You eight! Follow me! Your first task will be to ascertain what other members of our first party survived!”

* * *

Stumbling up a steep corridor, with the lash of the ruby eye’s electrostatic lightnings to spur him and the others on, Tupaia felt his mind racing out of gear. He was staring around this hellish place in terror in one moment, in an­other reliving the days when he drove a bulldozer for the island’s new airstrip to pay his college tuition, when he plucked red hibiscus for the tourists’ breakfast tables, ran errands at the Chinese store, lit spirals of pyrethrum to kill mosquitoes because a bug-zapper would not have looked authentic enough for the hotel’s whiteskin manager. Bug- zapper! Suddenly the parts of his memories came together. All around them swarmed a huge cloud of tiny beings, larger and faster than any mosquito and far more danger­ous. Boaty-Bits, he knew.

And suddenly wondered how he knew. And that weird being with the whip was a Sirian eye. Those other horrid beings had names too: the great doughy creature inside a crystal shell was a Sheliak; the clattering, hissing metal thing a Scorpian robot. But how did he know that?

Although Tupaia knew something about tachyon trans­portation because everyone did, he had had no direct expe­rience of it—this Tupaia had not—and little knowledge of its refinements. They had not seemed relevant to the prime goal of freeing Polynesia from its whiteskin conquerors, nor had it been discussed in his school classes. “Editing” was a concept he grasped only dimly, and that more by seeing what had happened to himself and the other Pur­chased People than from any theoretical knowledge. He did not need to be told that he had changed. His own hands, as they swung by his sides, testified to that most inarguably. And he could not fail to know that he now had faculties he had never owned before. He knew the names of these outlandish beings. He seemed to understand every communication addressed to him, in whatever language; he saw in colors he had never seen before.

“Halt!” cried a voice—not a voice, but a rattling like drumbeats; but Tupaia understood it, and knew that it came from the robot. The grotesque gnomes stopped, whis­pering to each other; they had passed through a vaulted chamber and were now on another balcony, higher up. Tu­paia edged away from the being that rattled and the being that stung as they conferred, and found himself near a pre­cariously low railing, looking down on the immense cavern itself. Now he could see that the things that scuttled around the machines and pipes were less unfamiliar than anything else in this wholly alien place; they looked exactly like the crystalline crabs that had begun to appear on Earth before he was transported. What they were doing, he could not make out. Repairing the machines? Perhaps so. A great plume of liquid was arching slowly out of some ruptured pipe, breaking up into a sort of rainbow spray, but the rainbow was made all of gradations of red, from almost orange to that newer, deeper red that he had never seen before. As he watched the plume dwindled and stopped, and he saw that the crystal crabs were swarming over the place it had come from.

Over Tupaia’s head the great ruddy eye dived past with a crackle of static electricity, and the Sheliak and the flying metal cube just behind. They plunged over the low railing and dropped like meteors to the far floor. They were after a huge translucent block with a keyboard at one edge. Something about the device troubled Tupaia— something not quite a memory, more than a dream—he could not pin it down. But the slave drivers had no doubts. Even at that great distance, even through the barrier of their queer shrieks and rattles, he could see that this object was something important to them.

Then the brief rest was over. The blood-red Sirian de­tached itself from the others and soared back up to the balcony, hovering just overhead. A sparkling sting jolted some of the kobolds to attention. “Here are your orders,” the Sirian rasped. “You indicated ones will proceed up this corridor until you encounter living beings or their corpses. Survivors will then return to report. Move outl”

There seemed nothing threatening in the long, narrow corridor they moved through. Away from the cataclysmic environment of the great machine chamber, with its wink­ing lights and scuttling, glassy crabs, the present tunnel seemed almost peaceful, and some of the other Purchased People began to speak almost normally among themselves. Tupaia disregarded them as a king-warrior should. He took the position at the front of the line as by right. No one argued. When he came to a gallery whose end disappeared in dimness, with branching corridors all along, he made the decision. “We will split up,” he announced. “One of you go into each of these tunnels. I will proceed along the main passage.”

There was a grumble from the other kobolds, but Tupaia paid no attention to that, either; except that when he had advanced a few score meters along the gallery he glanced covertly over his shoulder and was pleased to see that the others were no longer in sight. Perhaps they had followed his orders. Perhaps they had gone in a cluster into the first tunnel they saw, or even returned to the great cavern; it did not matter, what mattered was that Te’ehala Tupaia was alone and unsupervised.

How often he had dreamed of a chance like this!

But, now that he had it, was it real? Was there anywhere to escape to? And even if there was, how could he escape from the hideous shape these enemies had forced on him?

For almost the first time in his life, Te’ehala Tupaia, paramount king-warrior, began to doubt his destiny.

He slowed down, almost idling, glancing into each of the side tunnels as he passed, but there was no evident hope in any of them. The gallery was bare and empty, apart from Tupaia himself and a single insect—or, more likely, a Boaty-Bit from the swarm he had left behind him—that danced above and around before him like a silent sentry. Which perhaps it was, Tupaia thought gloomily; perhaps here too his freedom was only an illusion.

He stopped, aware that the Boaty-Bit’s dancing had be­come agitated, and aware of something new. It was not a sight or a sound. It was an odor, of such choking foulness that his armored nostrils tried to close to keep it out.

He knew that stench, with the queer new knowledge that had been grafted into him in the editing; and he ran for­ward to peer into the next tunnel.

A Watcher! The name flashed into his mind, and with it the sudden internal warning: Beware. But the warning was too late; the creature rose up to confront him.

Tupaia had never imagined anything as repellent. It was crouching over a half-eaten corpse, he saw with disgust—a human corpse? At first flash he thought so, for it wore the rags of clothes; but it was too small to be an adult human being, too incongruously proportioned, with long, skinny arms—no. With only one long, skinny arm; because the Watcher was crunching the marrow from the severed other, which still retained rags of a once-gay scarlet and green jacket.

The creature fastened its great eyes on Te’ehala Tupaia and dropped the arm. With a hoarse, hooting roar, as pow­erful as the whistle of a tour liner at the docks of Papeete, it plunged toward him, black enormous ears cupped in his direction, bulging multiple eyes glaring horridly. Blood was dripping from its hideous beak.

The creature was incredibly fast. There was no time to react, and he was weaponless. Tupaia could see that the beak was powerful enough to crush even the leathery chitin that was now his skin, that the coarse, reptilian wings ended in strong talons, that in one of the writhing pink tendrils which served it for arms it held a huge-bladed knife. Any of those weapons would have been enough to kill him; but he could not move away.

What saved him was a sudden bass bellow—”Drop to the ground!” It came from an unseen tunnel to his side; and a great, bronzed figure leaped out. It carried a crude spear, lunging at the Watcher. The beast, disconcerted by the sudden attack, veered away, soared past Tupaia, and blundered on down the gallery.

But Tupaia did not even turn to look. Two things had driven his danger out of his mind. The first was that the shout had been in Polynesian.

The other was that the man who had driven off the Watcher, the golden-skinned giant who leaped out to save him, was himself. Scarred, limping, with a bloodied rag wrapped around one arm—nevertheless, the savior of Te’ehala Tupaia was Te’ehala Tupaia.

For Tupaia—for both Tupaias—the unexpected meeting was shocking in ways that went beyond even the terrible shocks instrinsic to the place and circumstances. The one saw himself hideously caricatured—squashed, wrinkled, hands like claws, armored eyes. The other saw the same powerful frame and flesh his mirror had always shown, but terribly torn.

The flesh Tupaia took a step forward, opened his mouth to speak—then grimaced and clutched his side. “You’re hurt!” cried the kobold Tupaia, and his elder twin smiled faintly.

“Worse than hurt,” he gasped. “That thing got me in the side, and the bleeding’s started again. But what—how— why do you look the way you do?”

“Whiteskin treachery,” the kobold said bitterly. “That’s all I know.” He glanced up sharply as the distant mad hooting of the Watcher sounded. “Is that thing likely to come back?”

His twin shrugged, then grimaced with the pain. “He’ll be back when he gets hungry again, that is sure,” he said grimly. “There are no other survivors.” He swatted irrita­bly at a silver-blue mote in the air, which turned and darted away. “Unless you count the Boaty-Bits, but the gods know what they’re up to. They’re no use even to the Watcher—he couldn’t get a square meal out of them!”

The kobold Tupaia bent to his self s side, probing the wound while they exchanged stories; when he looked up his gnarled face was grim. “Don’t say it, my brother,” the flesh-and-blood one said softly.

“I don’t know what you mean!” the kobold flared. “Come on! I’ll help you down to where the others are. We’ll get you medical attention—”

The flesh one laughed gently. “How hard it is to lie to yourself,” he said. “We both know, Te’ehala Tupaia, that this Ce’ehala Tupaia at least has not long to live.”

“We don’t know that unless we don’t try!”

“We do know it. But, yes, we will go to where the others are, because there is no better choice. I could not find my way back to the surface—and they, at least, have a tachyon transporter. So perhaps one of us, at least, can both die and live.” He cocked an ear to the hooting that sounded again. “Help me!” he commanded, and they limped back toward the larger gallery.

The kobold glanced once at the maimed body of the dead chimpanzee, then resolutely looked away. Even though the flesh Tupaia was grievously wounded, it was not hard to travel in that gentle gravity. They were through the gallery, and the sounds of machinery from the great, hot cavern were growing louder, when the kobold felt his wounded brother stiffen. He pulled away and tried to level the spear.

A figure stepped out of a tunnel to confront them. It was a tinier version of the kobold Tupaia’s own armored shape, staring fearfully at them out of startlingly bright green eyes. “Please, mister,” it begged, “don’t hurt me! Put down that spear. I’m lost! My name is David Doy Gentry, and I don’t know what’s happened to me!”

The kobold Tupaia growled, “What the devil are you doing here?” But his other self put a hand on his shoulder.

“Don’t you see the boy is terrified? Answer him, boy.”

“I wish I could,” David-the-kobold sobbed. “I just wanted to see what it was like inside the tachyon chamber. That’s all! And then all of a sudden I was here with you other freaks, and—” He stopped, his hand to his mouth. “Oh, I didn’t mean to hurt your feelings!”

“You didn’t,” the gnome Tupaia said angrily. “You were part of the group of Purchased People? A child?”

“I didn’t mean to be,” David apologized. “And then that ugly big red glass eyeball sent you others up that way, and the rest of us just stayed there. And then some of them came back with a bunch of those Boaty-Bit bug things, and all the freaks—I mean the real freaks, mister— I anyway, they were talking together, and finally the eyeball thing told us that there weren’t any survivors of any im­portance from the other expedition—whoever they were— and we were to move along. So they did. All of them ex­cept me. I hid. I didn’t like that big eyeball!” He moved over to the railing of the balcony and looked down, nod­ding. “Yeah, you can see them now—they’re down there in that other place, where they left all the bundles. I don’t know what—oh, gosh! They’re all jumping off the bal­cony!”

The kobold Tupaia leaped to the rail, peering over. It was true! One by one, the squat, tough Purchased People were launching themselves into the abyss, while the eyeball and the Sheliak and the Scorpian robot flew nearby, driv­ing them on. The three on the upper ledge watched incredulously as the ugly gnome bodies fell in slow motion toward the distant bottom of the cavern. It looked suicidal. But the captors had made an elegant calculation of forces. In that weak gravity, the long fall was survivable—just. Each one in turn struck—struck hard, but not harder than their armored bodies could take. Each one stood up and waited, as the slave drivers gently dropped after them.

It was hard to see what the party was doing once they reached the bottom, since the ruptured pipe had laid a cur­tain of mist over much of the cavern. But they seemed to be loading up with burdens—that translucent block the big­gest—then forming ranks and moving on.

The kobold Tupaia straightened up. “Now what? We can’t stay here!”

The injured man shook his head. “Nor get back to the surface,” he said. “We must follow them.”

“No!” roared the kobold. “The boy and I could survive that fall—you could not!”

“There is no other choice,” the wounded man pointed out. “And—have you forgotten, Te’ehala Tupaia, how strong Te’ehala Tupaia is? It is true that I am not at this moment at my strongest, but nevertheless we have no choice.”

He broke off, for the mad hooting had sounded again, and this time very near.

The three on the ledge turned to meet the challenge, as the Watcher brayed once more and dived out of the tunnel at them. The kobold Tupaia shouted in rage; he was bare handed, and the slick red armor that covered the Watcher’s belly was far too tough for him to harm. The boy shrank silently behind him; and the Tupaia of flesh, the only one armed at all, stumbled to the fore, slowly bringing the crude spear around. Grunting with pain, he stabbed it di­rectly into the wide red mouth beneath the beak and was borne down in the monster’s rush. Tupaia-as-kobold saw his chance. The Watcher shrieked in agony, and the grip of its slimy pink tendrils loosened on the knife; Tupaia/ kobold snatched it away and plunged it into the glitter of the many-lensed green eye. The hard red belly armor smashed him down. The great wings folded in to trap him in their suffocating reek—

But there was no strength in them, and as Tupaia/ kobold fought free of them he realized that the monster was dead. Gasping and retching, he thrust the stinking form away and saw it float down into the depths of the cavern. He shouted with exultation and turned to his flesh brother.

There was no answering shout.

The long beak had finished what the earlier wounds had begun. The kobold looked, sorrowing, at the great golden- skinned form of himself, still now in death, yet holding the broken spear.

The boy moved behind him, and reached to put his hand in Tupaia’s, the bright green eyes sad in the comic gnome’s face.

“I’m really sorry about your friend,” he offered. And, a moment later, “What should we do now?”

Tupaia did not answer at once. He had no answer to give. He released the boy’s hand and stepped forward to the low rail, peering down into the misty distances of the cavern. Most of the damage had been repaired by the hard-working crabs, and he could see that hordes of them were slowly removing broken beams and replacing them with new. The party of Purchased People with their bizarre captors was vanishing into another tunnel far away. He lowered his gaze and reached out to touch the calm brow of his dead other self.

What should they do now? What a good question that was!

Apart from the obvious practical problems, Tupaia dis­covered an internal problem. He was having a sort of crisis of conscience. He had always had strict priorities governing every act of his life—the cause first, himself second, every other claim on his loyalties far behind. But Free Polynesia was despairingly far away. And this child, this innocent victim—could Tupaia just walk away from his needs?

He could not. He took the boy’s hand in his own again and said, “We’ll follow the others. Far back, keeping out of sight. And then—”

But there was no way of finishing that sentence. “Let’s go,” he said instead. “Hold onto my hand. You can close your eyes if you want to.”

And the two strange figures stepped off the rail into the immense abyss.

If the boy became a hindrance, Tupaia would abandon him. If the boy resisted, he would kill him. Tupaia’s deci­sion was clear and hard as the steel point of a javelin. And yet as time went on, and they went farther down and far­ther, the hard edges of the decision softened and receded into the background of his consciousness. The boy did not question. He obeyed every instruction Tupaia gave him; he followed without argument even when it was into a place, and through a means, terrifying even to Tupaia. The great leap into the cavern was not the last such jump they had to take, nor the worst. And still they went down and down and down.

They were lucky—in two ways they were lucky. The first was that the party they were following was heedless of pursuit; they left bits of wornout equipment, twice dead kobold-shapes, and very often there were bits of food in the trash. That heaviest of burdens, the somehow sinister trans­lucent block, they did not leave behind. But everything else seemed expendable. So they were easy to follow, and their leavings helped keep the pair alive. The second bit of for­tune was that their downward path passed now and then through caverns or wide galleries where things grew and even small animals moved about in the vegetation. Some were edible. Unfortunately, they could not know which un­til they tried, for city-bred David and island-born Tupaia had little experience of trying to live off the flora of a dozen different climates and environments. Appearances could not be trusted. In one rose-lit tunnel they found vines with a bright orange, fist-sized bud growing in profussion; they looked almost like rather misshapen papayas, and Tu­paia plucked one in hope. It felt slightly warm, and the slick surface yielded a little, like a tightly inflated balloon. But a faint sweetish odor clung to his fingers, and he sliced into it with the broad knife that had once belonged to the Watcher.

The glowing orange skin yielded to the edge, then rup­tured with a sharp pop. David cried out in alarm, as a puff of reddish vapor exploded toward Tupaia, almost like a spray of blood. The odor was strange and unpleasant— almost etherlike, edged with something sharply acrid. The vapor filled Tupaia’s nose and lungs like the quick, hard rush of a narcotic; he flung the fruit away, but he was dizzy and trembling, and for the next hour and more it was the boy who guided Tupaia’s steps, until the toxins worked their way out of his system. Eventually the gallery broad­ened and became distinctly warmer, and off to one side there was a tepid pool of water. They drank their fill. When they saw one of the great glassy crab shapes sidling along the bottom of the pool they ignored it; there were too many other worries and wonders, the glass crabs had lost their power to interest them.

And, after a brief rest, down, and down, and down.

Calculating from the point where they had fought the Watcher, Tupaia estimated they had traveled at least a dozen, perhaps twenty or more kilometers straight down on the trail of the Purchased People, twenty times that in hori­zontal tunnels and gradual declines. It was good that their edited bodies were tough and strong; even Tupaia’s own huge frame would have been seriously taxed by these exer­tions, and the boy would surely have collapsed long before. They seemed to need far less food and water than before— another blessing, for sometimes those were scarce. They moved on, through odd, dome-shaped rooms, with incom­prehensible metal rods glowing in dozens of hues, and skirted the edge of a vast vortex of water, slowly spinning and emptying itself into some unknown farther depth.

And, as time passed and they descended deeper and deeper into the unknown, Tupaia found himself beginning to care about the boy. Tupaia was in a turmoil of confusion in any case. Free Polynesia, which had been the core of his life, was now irrelevant. He was scared, and raging, and confused … but there was David, who needed him.

If someone gives you trust, it is hard not to try being trustworthy.

Another gallery, opening into still another great abyss. This one had no railings at all, though spikelike projections jutted from it over the yawning gulf. This one they did not dare jump; they skirted the edge and found a continuation of the downward trail.

A shallower jump—ten hours later—which left them on a broad, flat plain, with the ceiling a hundred meters over­head and palely glowing. “It looks like a farm,” David whispered; and it did. Geometric patterns covered the wide space, in every shade of green and black and brown, of gold and red and orange; and indeed crops were growing there. Growing for whom? Tended by what? Tupaia could not guess; but the tubers at the base of the dark-green plants were good to eat, and pale yellow fruits in the ad­joining plot relieved their thirst; and they went on.

And down.

And the air grew warmer.

It was nothing like the searing, steamy heat of the great machine cavern with the ruptured pipes. The levels they passed through now were gentle enough in climate; there was really no longer any need for them to wear the horrid gnome shapes. But, definitely, it was warmer. They dropped from another gallery onto another great, wide space, but this one was no farm. It was sheer, burnished metal, almost ILke a steely, oil-smooth sea that reflected a steely sky a hundred meters above. Now Tupaia saw what he had not seen earlier: rows of thin columns, widely spaced, that joined floor to ceiling. “It’s like we were in one shell after another,” David murmured, staring around. And Tupaia nodded; so it was. But shells of what?

At the end of the next passage that question, with all other theoretical questions, was driven from his mind.

David saw it first and cried out in alarm. Then Tupaia, close behind, saw it too: a heap of three more dead bodies. One was the gnome-shape that had once been a young, long-haired blond girl; one a middle-aged woman; and one not human at all. It was the Sheliak, its crystal shell long gone, its body now stretched and still in death.

“What—what could have happened, Mr. Tupaia?” the boy gasped.

Tupaia was silent for a moment, then met the boy’s bright green eyes. “They killed each other in a fight. They’re criminals, David,” he said harshly. “Same as me.”

“No! You told me what you did—you were fighting for a cause—”

“I thought I was,” Tupaia agreed, “and I still think the whiteskins wronged my people. But these others—killers, most of them. Psychotic killers! When they were released from ownership I guess it was only a question of time.” He turned over the girl’s body with his foot, then hastily turned it back before the boy could see. One whole side of the face was a cinder; evidently the Sirian eye had been involved in the fight as well. “Two here,” he muttered, “and four others that we’ve passed on the way. Probably some others dead, too, that we didn’t see, or that wandered off. It’s been an expensive trip.”

The boy clutched his arm suddenly, and pointed at an opening just beyond a cluster of bright red metal columns. Tupaia could feel him shaking, but his voice was steady as he said: “Real expensive, Mr. Tupaia. There’s some more!”

It wasn’t just a few more; if the little group at the end of the passage had indicated a fight, this one showed pure massacre. There were more than a score of bodies—all hu­man, this time—and most of them showing terrible burns. Tupaia shook his head. “Something set this off,” he said. “I wish we knew what.”

David looked up at him. “Should we go look?”

Tupaia shrugged. “We don’t have a choice,” he said, and heard the echo of his own voice saying the same thing, over and over. “Come on—but be careful!” he commanded and led the way past the heaps of corpses—

And brought up short.

They emerged onto another gallery, this one, it seemed, the last. For there below them was … empty space.

David cried out, and Tupaia caught the boy to him, star­ing incredulously. The next level was transparent, and be­low it nothing but a distant, far-down bright star. A sun! It was redder and brighter than Earth’s could have been at such a distance, but unquestionably a star, trapped inside a great crystal shell, with all the rest of Cuckoo enveloping it in spherical layers.

Tupaia knew then what had driven the Purchased Peo­ple over the edge of sanity; he felt his own threatened by a terrible vertigo and fear.

And a new fear added itself, for between the savage blaze of the trapped sun below and the shining metal roof above, something moved. The movement was a swarm of things, and Tupaia’s first thought was that they were Boaty-Bits. But that was wrong. They were far too large, and even at great distance he could see that they possessed structure—wings and tails—Boaty-Bits were not like that. They were clustered around a distant structure like a bridge, narrow and unrailed. It leaped across that terrible gulf without cables or piers for support, and at the end of it a strange object hung. It was ball-shaped, and one hemi­sphere of it was mirror-bright, the other dead black. It looked almost like the sort of diagrams they had shown at the mission school to explain the Earth’s day-night cycle, half sunlit and half in shadow. The black half was on top, the bright half beneath. It seemed to float above the center of that vast, glasslike floor, but he saw other bridges spun to it, far away and looking tiny as the threads of a spider’s web. Things here had little weight; perhaps they were strong enough to hold it up. If those bridges were like a web, the queer ball hung upon them was like the spider’s nest. Could there be some kind of spider-thing inside?

He shaded his eyes against the glare of the sun below to see the moving things. Watchers! Scores of them, an army. They were not flying. Ugly wings folded, they were creep­ing on their bellies across the bridge, as if stalking the great spider he imagined. One of them carried a clumsy-seeming, boxlike tachyonic transmitter strapped to its back. Some­thing else was strange. Peering again, he saw that all their ugly heads were covered with queer, ill-fitting helmets. Looking at the head of the line, he saw that the leader was not a Watcher, but one of the hateful triangular things called deltaforms. It, too, was queerly helmeted.

In the vast space above them, insects were swarming— no, not insects; these were indeed Boaty-Bits. A nearer cloud of them swept toward Tupaia and the boy, attracted by David’s cry. And beyond them Tupaia could see the Sirian eye and the Scorpian robot, floating over the great translucent block and the bodies of the remaining Pur­chased People.

“Oh, what’s wrong with them, Mr. Tupaia?” the boy gasped. Tupaia could not answer. The koboldlike figures were strangely contorted, as if frozen in a rapturous con­vulsion; they seemed to have been caught in the middle of some terrible tetanic spasm.

But the Boaty-Bits were nearer. “They’ve seen us!” David gasped. “Mr. Tupaia, we’d better get out of here!”

Tupaia didn’t answer. No answer was needed. He grasped the boy’s hand and towed him, in great slow bounds, back into the tunnel, past the heaped corpses, back into the great wide gallery, past the riven form of the She­liak, back along the wider passage—

And stopped short. Far down the passage other forms were approaching, great, hideous winged beasts that bore riders on their backs. He groaned in frustration, as David made an inarticulate sound and jerked his hand from Tu- paia’s. “David!” the kobold cried. “Come back! We’ll look for another tunnel—”

But it was too late. The boy was running down the pas­sage toward the great flying beasts; and as he neared them the one in the lead stopped, with a flurry of wings. A woman seated behind the rider slipped off, an incredibly tall, lean woman; and David ran up to her, crying, “Mama!”


Living with the Kooks was more tedious than fright­ening, but it was frightening, too. There were at least ten of the giant glassy crabs, as well as countless smaller ones, down to the size of a quarter. The crabs seldom slept. There was never a time when one of the big ones was not near Jen Babylon. He thought of them as his guards; no other term fit them, although they presumably had other functions, too, since they could not have been stationed there simply on the chance that he might arrive. But they guarded him. If Babylon wandered too near an outside door, one of them scuttled between him and it. If Babylon got in the way of something that was going on, one of them warned him off, talking to him in that curious, tape- recorded manner of speech that they possessed, or simply rose up silendy before him. Which was warning enough. He was never harmed, or even touched, but the message was clear. As a linguist, he could not help observing their strange speech patterns. Puzzling at first, they became clear in a burst of comprehension. The crabs simply copied words spoken to them! Somewhere, inside their arthropod bodies there was an information-processor not unlike a Pmal. The more language they heard, the more they could repeat and use. The larger ones spoke in almost normal vocabularies, though stiltedly; the smallest ones seemed to have to learn as they went along.

There were at least half a dozen human Kooks—if you could call them human! If they would stay still long enough to be counted! They were not kept prisoner in the apartment, like Babylon. They came and went freely on mysterious errands, and on some not so mysterious. Some of them left bearing little packets of what looked like dia­mond dust—he did not at first see where it came from— and returned hours later, if they returned, usually with shopping bags full of food, sometimes with what looked like simple trash scavenged at random. The scrap went into the bathtubs of the joined apartments—bits of iron, chunks of rock, shards of broken glass, odds and ends of unidenti­fiable debris. (So much for bathing! Which accounted, partly at least, for the way the human Kooks smelled.) The food became the diet for the humans in the apartments— weird mixtures of things like lettuce and honey, eels and carrots stewed together; the tastes were indescribable and sometimes awful, but the Kooks did not seem to care, and Babylon’s complaints were laughed at. Or, more often, ig­nored. At odd intervals throughout the day an old- fashioned electric alarm clock would go off and the Kooks would stop whatever they were doing to prostrate them­selves, chanting, before the larger crabs—which seemed, if anything, amused, if you could be sure of detecting amuse­ment in a glass crustacean.

“Why can’t I leave?” Babylon demanded, and Sheryl placed her hand over his.

“You aren’t one of us,” she said with tender reproach.

“I don’t want to be one of you! I just want to go back to my life.”

“We must all do what Cuckoo gives us to do,” she told him seriously. “Let your soul open to the Savior and De­stroyer, Jen, hon! You will find such peace!”

He sighed. He had not been able to get a rational word out of her. “What I really want,” he said bitterly, “outside of getting out of here, is a bath.”

She laughed sweetly. “That’s not possible just now, Jen.”

“Then I want to go to sleep,” he muttered.

“Of course! I, too. Come along, hon.” And she led him into one of the bedrooms. There were twin beds, and each of them was occupied by two Kooks, lying on bare mat­tresses with an old army blanket pulled over them. There was a strange bulge in the middle of each bed. Sheryl leaned over the couple in the nearest bed and whispered softly to them. They woke instantly, smiling, and threw off the blanket. They rose from the bed, genuflected to the single crab that crouched on the dresser, and left the room. “Time for bed,” Sheryl whispered tenderly. “Come on, Jen, hon!”

For a startled moment Babylon felt a quick priapic shock; but he had mistaken her meaning. This was no invi­tation to the sort of bedding they had shared so often be­fore. Even if she had wanted that—with the two other Kooks snorting gently in their sleep in the next bed and the glassy crab clattering softly as it stirred on the chest—there was an obstacle. The lump in the center of the bed revealed itself as a prim reminder of old New England. A bundling board! It was an old ironing board, really, with the legs snapped off; but as Sheryl got in on one side she propped it between them as she held the blanket for Babylon to climb in on the other.

“Good God,” said Babylon, “is that thing necessary?”

“It’s better to have it, hon,” she whispered soothingly. “Hush, though! Please don’t wake the others.”

“Better how?” he demanded, but obediently lowering his voice as he slipped under the blanket.

She closed her eyes and spoke dreamily. “It is a symbol, hon. Sex is over. Reproduction is over. We are fulfilling our vow to Cuckoo the Savior and Destroyer.”

“And what’s the vow, exactly?”

She said with pride, “We are voluntarily becoming ex­tinct! When Cuckoo comes, the worlds awaiting him will be nice and clean—and empty! And, oh, what bliss for our Galaxy to serve him in such a way!”

When Jen awoke it was daybreak, and Sheryl was gone. Her place in the bed was taken by a short, dark man with a beard, snoring away. Babylon lay there, trying to reconcile the queer turn his life had taken with the almost as queer dreams that had disturbed his night—sexual dreams, with the smell of Sheryl in his nostrils; imprisonment dreams, perhaps sparked by his captivity, perhaps by the bundling board that kept him from his lover—or former lover, strange dreams of vacant worlds waiting a redeemer. He lay with his eyes tight shut, contemplating the dream world. They all had sensible roots in reality—all but one. What to make of that dream, so vivid, so frightening for reasons he could not identify, of a great jewel-studded chamber with glowing walls, where something terrible was happening?

He shook his head, opened his eyes, got up, and exam­ined what was for breakfast. It appeared to be a soup of uncleaned spinach and unshelled shrimp; he shuddered and turned away. He could not eat that, so early in the morn­ing.

Which left him with nothing to do at all. Sheryl was not in either of the apartments at that moment. None of the other Kooks seemed disposed to conversation. He prowled the rooms, dodging crystal crustaceans and flesh-and-blood Kooks with equal repugnance, and finally settled on a win­dow with bright morning sun coming in, where at least he could gaze on freedom.

Although the building Sheryl lived in was not very old, it was in Boston. Therefore it was preserved, though centu­ries past its prime. It looked out on the sort of backyard Boston tenements had had since the early days of electric­ity, rectangular plots, each with its postage-stamp square of grass and its scattered, sickly shrubs and its ailanthus tree. And, across the garden, ancient Irishtown flats, also pre­served. “Historical landmarks,” they were called.

They were not beautiful. But Jen Babylon sighed, wiped his glasses and replaced them to stare at the buildings with longing. The roof of the nearest of them was no more than a meter from the little balcony outside the apartment win­dow. An easy jump …

An impossible jump. Impossible, because every square centimeter of that balcony was occupied. The entire floor surface was filled with crabs, small ones, torpid in the Bos­ton sun—such as the Boston sun was. But such as it was they seemed to need it. They spent every sunlit hour soak­ing up radiation. When the shadows shifted to darken the little balcony they would scratch and clatter their way back into the already crowded apartments to cluster around the electric heaters that were kept going day and night. Baby­lon found himself sweating and begged relief of one of the Kooks, without result. The gaunt old lady he addressed merely told him—very sweetly!—that this small discomfort was a tiny price to pay in die service of the Savior and Destroyer.

He tried again with Sheryl, when she came back into the apartment with one of those loads of miscellaneous trash, and she listened, vaguely sympathetic, but gave him the same patient answer. “But whyV he demanded. “Don’t we smell bad enough already without making us sweat?”

She laughed sweetly. “It’s for our brothers and sisters, the Lambs of the Maid,” she explained, nodding lovingly toward the nearest of the crystal crabs. “They have to have thermal radiation to survive. That’s why they were sent first to the tropics, where they do really well—here not so well,” she said sadly. But then brightened. “But look, hon! I know you don’t like our food, so I got you a special treat!” And she pulled out of the shopping sack a six-pack of peanut butter and cheese crackers.

He turned away—but then reconsidered and took it.

He could not even use the shower for relief, for the bath­tubs were filled with the dirty, debris-strewn water he was forbidden to disturb. So he stared longingly out of the win­dow most of the time, and pondered schemes. When all the crabs came inside for warmth … When, somehow, they forgot to lock the windows one time … When everyone was asleep at once …

But there were no such times.

Apart from that, he was fed when he needed it, allowed to talk to the human Kooks when he was inoffensive in what he said, given as much room to fall down in as any­one else … until the time when Sheryl answered a coded knock at the door of the smaller apartment, murmured briefly to someone inside, and then came to his window to call him. “Jen, hon! Come and see! We’ve got company!”

As he started to turn he hesitated, his eyes fixed on the rooftop next door.

A moment later he said, as calmly as he could with his heart thundering in his ears, “All right, Sheryl, I’m com­ing.” And he resolutely did not look toward the window again, though it took all his strength to keep from smashing it open to shout at the figure he had barely glimpsed, peep­ing from behind a pigeon roost, with its fingers to its lips.

It had looked very much like Ben Pertin.

Sheryl’s surprise was the Crystal Maid herself, the same one Babylon had seen on the beach at Moorea, and she was not alone.

She laid her hand on the shoulder of the giant who en­tered with her and spoke in slow, chiming tones, which sounded like snippets from an artificially generated speech program. “This man is to be … treated … as a full and equal … comrade among us.” She turned her dia­mond eyes on Babylon. “Why is this … person … here?” she demanded.

Sheryl apologized quickly, “He came looking for me, and I didn’t know what else to do with him. He can’t get away.”

The Maid seemed to meditate for a moment. “I … know this person,” she announced. She stared at him for a moment longer, then dismissed him. “He may remain. Now … I wish to see … the Lambs!”

Babylon’s eyes were studying the man who had come in with her. He was tall, bronzed, with wide shoulders; he towered over everyone else in the room, and Babylon rec­ognized him. Of course! He had seen that bronzed face on the news stereo often enough, had even seen him in person, with the other convicts at the Tachyon Base. Te’ehala Tu­paia! The mad revolutionary who had been captured while he was still in Polynesia!

Tupaia seemed to have come down in the world, for now he appeared to be a slave to the Crystal Maid. He came in burdened with shopping bags obviously strained to capac­ity. They proved to be full not of food but of sand, salt, pieces of scrap metal. A couple of the largest crabs reared up and took them from him, and Tupaia turned to look contemptuously at his surroundings and at Babylon.

The entrance of the Maid had produced a great stir, with all the humans abasing themselves to her and even the crabs seeming to genuflect briefly before taking the materi­als from Tupaia and clattering off to the bathrooms with them. When the Maid had completed her inspection, she summoned all the human Kooks to one room and closed the door, leaving Babylon with Tupaia and two great guardian crabs. The Polynesian paid no attention to them. He turned away from Babylon and found himself a plate of the greasy stew the occupants of the apartment had been preparing—lentils and salt pork, with what seemed to be turnip greens floating in it—and began to devour it.

Babylon approached him. “They haven’t been feeding you much, have they?” he offered, staring at the gaunt cheeks.

The giant glowered at him for a moment without an­swering, but finally he shrugged and nodded, his mouth full. When he had stuffed a full kilo of the mess down his huge throat he was even willing to talk. Not out of friend­ship, surely; mostly out of disdain. Only when Babylon asked about the look he had intercepted in the Tachyon Base did he pause to laugh. “It is true,” the giant said con­temptuously. “I was not as the others! I am Te’ehala Tu­paia, paramount king-warrior of the forces of Polynisie- libre, and not a common convict.” Evidently, Babylon discovered as the giant boasted on, Tupaia’s distant owner had either died or lost interest, and the slave had found himself free. But only relatively free. If he was not domi­nated by the master within his mind, he had remained a prisoner all the same—until in the confusion of the Kook demonstration at his hearing he had managed to break free. Since then he and the Crystal Maid had been running strange errands, skulking and hiding by night. The Maid, said Tupaia, for the first time subdued, seemed to have much manna.

Babylon coughed and ventured, “But do you, ah, believe in all this stuff about Cuckoo the Savior and Destroyer?”

Tupaia grimaced. “I do not invest belief in the doings of whiteskins,” he said, and would say no more.

The conference in the bedroom was over, and Sheryl came out to supervise what the crabs were doing. Babylon followed, peering over her shoulder, and at last the purpose of those stagnating pools of trash and water in the bathtubs became clear. The crabs, with help from some of the Kooks, patiently fished out all the larger, undissolved bits of debris. Then, gently and carefully, they sieved out of the murky stew what seemed to be thousands of tiny new crabs! The larger ones carried the infants to the balcony and placed them in the sunlight, then refilled the tubs with the litter of rock and sand and metal and ran water to cover them.

Then, lining up like a students’ queue at the registrar’s office, the crabs did the strangest thing of all. One by one the largest ones came to Sheryl, who patiently began strok­ing their undersides—like a milkmaid, Babylon thought— catching in a bowl a fine rain of diamond dust from each. When she had finished her chore she packed some of the dust into little plastic bags and handed them to Tupaia, who silently stowed them away in the shabby shopping bags. The rest she sifted meticulously into the tubs. Then she rose from the side of the tub, sighing as she stretched her cramped leg muscles, and caught sight of Babylon gawking incredulously. “Oh, Jen, isn’t it wonderful?” she said, glowing. “In just a few days there will be thousands of others to distribute around the city!”

“Thousands of, for God’s sake, what?”

“Why, of Cuckoo’s dear Lambs, of course,” she ex­plained. “We hatch them here, because it’s so unpleasant for them out in the open, this far north. Then we release them. Or the Maid spreads the seeds in the water—along the Charles, down by the Bay, in the park ponds, anywhere where there’s water and sunlight and minerals to make their beautiful bodies. But there’s not a lot of sunlight in Boston,” she said regretfully. “So some of the poor darlings that try to grow in the river just don’t make it. But the ones we grow here—ah, they’re perfect!”

She patted Babylon’s cheek gently, and then ran to an­swer a knock at the door. “Oh, you’re here!” she cried joy­fully. It was one of the skinny, bearded, filthy Kooks, and he was incongruously carrying a box and packages from Filene’s department store. Sheryl set them on a table and began opening them eagerly. For a moment she looked like the old Sheryl, thrilled with new clothes, excited by cosmet­ics. But it turned out the finery was not for her. Some of the clothes were a man’s, in giant sizes, for Te’ehala Tu­paia. The rest were for the Crystal Maid, and so were all the cosmetics.

Sheryl caught sight of Babylon’s gaze and shook her head ruefully. “Isn’t it a pity to cover up that beautiful person?” she asked. “But she’s so conspicuous, you see, and this way she’ll be able to move around the city on Cuckoo’s work without attracting so much attention. —Now excuse me, hon, but I’d better get to it!”

Pancake makeup, covered by blusher and powder; eye shadow and mascara; when Sheryl was finished the Crystal Maid was crystal no longer. She looked, if anything, like a bartop dancer in a Combat Zone honky-tonk—but at least she did not look like the alien creature she was. And she and Tupaia—now resplendent in conservative flamingo- pink tunic and slacks, with dark glasses and a jaunty be­ret—took up the sacks of demon seed and went out.

As soon as the door was closed, the tempo in the apart­ments slowed down appreciably. Sheryl slumped down on the shabby living-room armchair, exhausted. “Wow,” she said, fanning herself, “it’s so good to work so hard for Cuckoo!”

She paused in fanning herself and looked critically at Babylon. “What’s the matter, hon?” she asked.

Babylon shifted position morosely. “Are you sure you know what you’re doing, Sheryl?”

“Of course I do! Hon, I wish I could make you under­stand. They are the true inheritors of Cuckoo. Everything we do is for them and him!”

“You mean the crabs?”

“The Lambs of Cuckoo, hon,” she corrected gently.

“Queer-looking lambs! And what about that criminal—is he a lamb, too?”

She shrugged patiently. “Mr. Tupaia is merely an instru­ment the Maid uses. He doesn’t matter. Even the Maid doesn’t matter, really—I mean, not in herself. She’s merely an edited version of the Lambs herself, you know. De­signed to be able to move around more freely in human society than they could—although if it hadn’t been for my idea about the makeup,” she added proudly, “it wouldn’t work so well! Apart from that, there’s nothing for her here on dismal old Earth—not with the human race as rotten with disbelief as it is! Even ourselves, really,” she added thoughtfully. “Sometimes I wish we were more worthy—”

The skinny old Kook with the beard standing near, came nearer still and scowled at her. “Fine talk!” he barked. “Are you weakening in your faith, Sheryl?”

“Of course not!” she flared. And then, repentantly, “But we all need to reinforce ourselves all the time, don’t we? Come! Let’s reconsecrate ourselves and worship!”

And she dragged Babylon down on his knees next to her, as she fell to the floor.

All around them the other Kooks were falling to an atti­tude of prayer, their faces enraptured. “Oh, glorious Cuck­oo!” Sheryl cried strongly. “Sacred redeemer! Heavenly visitor! Our Savior and Destroyer, we give you our worship and our love! Let your coming be soon—if it please you— and let us go content into the darkness eternal, fulfilled in the knowledge that we have made way for your coming—”

She didn’t stop. She was interrupted. There was a sud­den peremptory banging at the door, and a man’s voice from outside bawled hoarsely, “Militia! Open up! In the name of the law!”

But the police did not wait for their orders to be obeyed. There was a rending crash, and the door was battered down. In flooded a mass of armed men and women, thick clubs in their hands, flailing at the crabs that failed to get out of their way.

* * *

Babylon was the first one out, helped by a husky militia-woman, stumbling down the fire stairs and into the street. “You all right?” she demanded, and turned to race back into the building without waiting for an answer. Babylon turned, blinking in the afternoon sunlight. The street was filled. Half a dozen militia hovervans purred in the road­way, on the sidewalks, wherever they had come to rest, while curious onlookers laughed and pointed as, one by one, the Kooks were dragged through the doorway.

And Ben Pertin, grinning broadly, squeezed through the police lines and came up to him. “I thought it was about time we got you out of there,” he said. “Don’t thank me, Jen. I’m just paying back what I owe you.”

Babylon said from the heart, “Well, I do thank you. I was going crazy in there.”

“I figured,” Pertin said modestly, and they paused as the militia led Sheryl, sobbing, into one of the vans. She caught Babylon’s eye and turned away. For some reason she made him feel guilty.

“Too bad about your girlfriend,” Pertin observed philo­sophically, “but I guess you’d have to say she brought it on herself.”

“What will they do with her?”

“Oh, nothing too serious, I’ guess—probably. Unless you want to press kidnaping charges?”

“No, no!”

“I didn’t think so. But I could tell from the way you looked you didn’t want to be there, and when I saw those damn animals all around you— Well. You probably want to know how I found you.”

“I sure do.”

Pertin’s expression was filled with self-satisfaction. “I went to the university to talk to you about … some­thing.” He hesitated. “Well, to tell you that things weren’t working out for me. I found they’re pretty worried about you. Especially that little girl, Althea. The cute grad­uate student? Anyway, she told me you’d been talking about Sheryl, so I came to take a look, and I listened at the door, and then I thought I’d better reconnoiter a little be­fore I knocked and maybe got grabbed myself!” He stepped aside, wrinkling his nose as the dirty old man with the beard came out, swearing furiously at the militiaman holding him- “I had a little trouble at first getting the mili­tia to act,” he complained, “but of course they don’t like Kooks. Or those crabs, either. They wouldn’t accept my theory you’d been kidnaped, but after a while they figured out a crime that had been committed.” He grinned. “‘Keeping dangerous animals in a populated area,’ it’s called. That was all they needed.” He paused, and added, “She’s real pretty, isn’t she?”

“Who, Althea? I thought Zara Doy Gentry was the only woman who interested you in the whole Galaxy!”

Ben looked shamefaced. “Aw—I went to see her, but she just laughed me off. Hell with her. Now, that Althea—”

For the first time in days, Babylon laughed out loud. “Spare me,” he said, turning to watch the militia as they came out with body bags made of tough netting, each one containing the squirming, clattering body of one of the larger crabs. Two others were staggering with a huge sack containing scores of the smaller ones. Babylon wondered what they would do with the creatures and, queerly, almost felt concern. After all, the crabs had not actually hurt him. Or anyone else, as far as he knew; they had not even de­fended themselves against the clubs of the militia, simply tried to get out of the way.

Babylon said, “Well, thanks again, Ben. I guess I’d bet­ter get back to the school to set their minds at ease. And I wanted—I mean, that other ‘I’ on Cuckoo wanted—some linguistic data from me. He’s probably—that is, I’m proba­bly—getting pretty impatient.”

Pertin’s expression was suddenly tense. “Oh, of course,” he said. “You couldn’t know what’s happened.”


Pertin shook his head fretfully. “God knows,” he said moodily. “But Tachyon Base announced that all communi­cation with Cuckoo has been cut. Terminated. The fault’s at the originating station. No signals are coming in. The

orbiter may have been destroyed, Jen, and what’s become of the you and the me that’s there, I can’t even guess.”

“I wish—” Babylon began, but what he wished was drowned out by a hissing, chittering sound that sprang from nowhere, seemed to come from everywhere, grew in volume—and then abruptly cut off. The human voice of one of the militiamen rose in the silence:

“The crabs! They’re having a fit!”

It was the crabs—all of them—but it wasn’t just the crabs. The human voices of the Kooks in custody had risen in hysteria, in the same way, and in the same way cut off. Babylon and Pertin were surrounded by stacked crabs in their mesh body bags, all writhing spasmodically, convul­sively—and then, all at once, they stopped, rigid in tetanic spasm.

There was silence. Then Babylon said wonderingly, “What was that all about?”

But Pertin was pointing at the hovervan Sheryl had been taken into. She was pressed against the bars, rapt, arms outflung, eyes to the sky. She held that painful, precarious pose for a long moment.

Then she shouted something unintelligible.

Pertin and Babylon looked at each other questioningly, then Babylon shook his head. “I didn’t understand,” he be­gan to say; and then Sheryl repeated it, louder than before and clearer:

“HE is waking!”


The ancient history of the human race was scarred with endless examples of genocides, witch hunts, and po­groms. Nero’s Romans hunting down Christians as scape­goats for the burning of Rome, Europe’s Christians ferret­ing out Jews to revenge the onslaught of plagues—Cossacks and Ayatollahs, Papal troops annihilating Catharists, Bos­ton zealots burning sick old women at the stake—the story of humanity was blotched with unsavory episodes of perse­cution.

But those were history! Ugly pages but forgotten ones, relics of a shameful past—and yet, on the orbiter, the purges and pogroms were being echoed with terrifying fi­delity, as the shocked and vengeful inhabitants sought out their betrayers.

Of the three hundred eighty-six beings on the orbiter, collective entities like the Boaty-Bits not counted, no fewer than fifty-four were found to be part of the conspiracy. Two Scorpian robots, four Canopans—not counting the dead one. Eight Sirians, a dozen Sheliaks, nearly all the deltaforms, and one or two each from dozens of other races. No T’Worlie was part of it. Neither was any human, apart from the Purchased People. And no race was com­pletely corrupted but one. The Boaty-Bits were one hundred percent among the forces of destruction. Two big swarms of them were destroyed, then only isolated mem­bers were seen, then none at all. “They’re hiding,” Doc Chimp whimpered, as he and Jen Babylon retreated from the scene where a furious Sheliak was methodically cre­mating the last scattered individuals of one swarm with his electrostatic whips. “Oh, they’re mean ones, Dr. Babylon!”

Babylon demanded, “But why? What are they doing it for?”

The chimpanzee stared at him morosely, scratching his jaw with long, black fingers. “Seems to me if we wanted to know that we’d have had to keep a couple of them alive to ask.”

“I don’t mean just the Boaty-Bits, I mean everything that’s been going on. All this strife and working at cross- purposes—from what you and Ben have told me, it’s been like that almost from the orbiter’s first days!”

The chimp was silent for a moment. Then he sighed. “Oh, even before that, Dr. Babylon. Back on the ship— back on Sun One—” He shook his head. “It’s been a mor­tal long time that people have been betraying and hating each other, Dr. Babylon.”

“I’m talking about here and now, and the Boaty-Bits!”

Doc Chimp nodded somberly. “They’re the villains this time, no doubt about that. Maybe we should’ve guessed long ago—’course, we didn’t really know they could take over other beings the way they do … But they’re collec­tive beings, Dr. Babylon. They don’t think like the rest of us, and they don’t much like us. Noncollective beings are too prone to individual aberration, as they call it. So they’ve been taking over individuals—the ones that were halfway rotten already, I expect, like the Sheliaks and the deltaforms, most of them—”

“That doesn’t tell me why!" The chimpanzee shrugged his narrow shoulders without answering. “I can’t believe that one single race could prevail against the entire Gal­axy!”

Doc Chimp said, “No, and nobody else did, either—else we might have done something about it. Maybe they’re not just one single race, though. Org Rider thinks there’s some­thing beyond them—”

“Org Rider!” Babylon cried. “That’s another thing! I haven’t seen him or Zara since—since I don’t know when, since before we found out about the Boaty-Bits, anyway. Where are they?”

The chimpanzee licked his narrow lips, peering fearfully at Babylon. “Could you please ask Ben that question, not me?” he pleaded. “It’s a kind of a—well, a secret, Dr. Baby­lon. I know Ben would tell you, but I promised.”

“Oh, for God’s sake! Now what?”

The chimpanzee was obdurate, though intimidated. “Please! It’s just—well, Ben can explain everything. He’s scared the Boaty-Bits might be anywhere, just one of them, you know, that might hear something and go back and tell the others.”

Babylon said furiously, “They’re only little bugs, Doc! They’re not gods!”

“Oh, don’t say that, Dr. Babylon,” the chimp said ear­nestly. “They’re pretty special! One or two of them are nothing at all. But put a few hundred of them together and you’ve got the beginnings of intelligence. A couple of thou­sand, like the swarms we’ve had here on the orbiter, and there’s a collective being as smart as you and me!” He laughed sourly. “And none of us was smart enough to take the next step. Ten thousand of them, a hundred thou­sand—Dr. Babylon, can you imagine what a million of them would be like? Why, I’m surprised they didn’t just take us over, long ago! The more of them there are, the smarter and stronger they are—and there’s just nothing we can do about it!”

Babylon nodded, beginning to appreciate what a power­ful foe they had in the Boaty-Bits.

He did not yet know how drastically he had undervalued them.

Ben Pertin was in his room, and not alone. Babylon pushed through the door, and stopped short. Hanging just before his eyes was the TWorlie, its butterfly wings wav­ing like gentle palm fronds to support its body. “Mimmie,” he said. “Are you all right now?”

“Statement: Physically well, emotionally satisfactory.” The five bright eyes peered at him with humor. “Query: Are you well?”

“I’m angry,” Babylon growled, peering around the room.

“You, Pertin! What’s the secret now? Where are Zara and Org Rider?”

Pertin snapped back, “Close the door, you idiot! Do you want the whole orbiter to hear you?” And then, when the room was secure again, he smiled with a look of silky self- satisfaction. “I got ahead of them for once,” he boasted.

“How? Who are ‘them’ ?”

Pertin said gravely, “Everybody who is not in this room, I think.” He nodded toward his companions—the T’Worlie, the silvery girl, and Doris. “We can talk in front of these three, so I can tell you that Zara and Org Rider are on their way home!”


Pertin smiled indulgently. “Oh, not the Earth. Org Rider’s home.” He gestured at the mural above his head of the huge mountain, and added in a superior tone, “If you’d studied the maps you would know that Knife-in-the-Sky is not much more than a thousand kilometers from that tem­ple by the lake—right next door, by Cuckoo standards!”

Babylon controlled his irritation as best he could, but there was an edge on his voice as he said: “Ben, I really do advise you to give me a straight answer. WhyT’

Pertin seemed to shrink before his friend’s anger. In a much more subdued way, he said quickly: “They’re getting orgs, Jen. If you remember what those tunnels looked like, they’re a long, slow hike on foot—but they’re mostly pretty high and wide. An org can fly them at least ten times as fast as the party did with the Purchased People walking every step.” He hesitated, then offered, “I, uh, I thought we ought to follow them, Jen.”

There was a squeak from Doc Chimp but Babylon didn’t even look at him. “Follow them?”

“Well, somebody has to, don’t they? Org Rider and Zara went by lander—I wanted them to use tachyon transport, but Org Rider has some silly superstitious objections to it— and they’ll meet us at the temple. With extra orgs, enough for all of us. Then we can just get on the orgs and—oh, dammit, Doc, what is it?”

The chimpanzee had been trying hesitantly to attract his attention. “Ben, who’s ‘us’? Do you mean me, too? And if you do, did you forget that that terrible beast has already killed me once down there?”

Pertin shrugged irritably. “We’ll go armed,” he said im­patiently. “We’ll go by tachyon transport, so we’ll be there before Org Rider and Zara—”

“Oh, no, we won’t,” Doc Chimp declared, pulling his leathery lips back in a scowl that bared his long yellow teeth. “Org Rider’s not the only primate that has objections to tachyon transport, and with me it isn’t superstition! I’ve been killed often enough! I don’t want to be killed any­more.”

“Then we’ll go without you!” Pertin snapped. “Well, Jen? What about it?”

Babylon temporized. “What about the others?” he de­manded, and the Purchased Person, Doris, spoke in her slow, unearthly voice:

“This one has already concurred.”

Babylon looked at the winged silvery girl, who met his gaze out of her calm, bright eyes. Her voice was like the sound of chimes as she answered: “I wish to go. I do not require an org to fly.”

Which left only the T’Worlie.

The little bat-butterfly of a creature had been floating silently over Pertin’s head, listening without saying a word. Now it spoke, and the Pmal gave its answer.

“Statement. Concur in desirability of proposal, express willingness to participate. Query: Is amplification or ex­planation desired?”

“My God, yes!” Babylon exploded.

The T’Worlie exuded its sour-lemon smell of amuse­ment. “Following is a synoptic series of statements and conclusions. Probability estimates vary, but in general ex­ceed point-nine. First statement. At some time t certain species, primarily the so-called Boaty-Bits, but with the as­sistance of individuals of eight other races of beings—”

Babylon groaned internally; you should never ask a TWorlie to explain or amplify! But once started, the little being moved on implacably through the entire history of the events on, in, and around Cuckoo: the private tachyon transporter that the rebels smuggled aboard and used with­out authorization; the private control mechanism they seemed to have developed for Purchased People, perhaps a hidden power of the Boaty-Bits; the expedition; the dam­age to the interior of Cuckoo; the fighting far under the surface of Cuckoo; the revelation that Cuckoo itself was an artifact … It went on endlessly; or so nearly endlessly that Babylon was astonished when at last the T’Worlie fell silent. “Well,” he said quickly, “thank you for—”

But the T’Worlie had merely paused, it appeared, for dramatic effect. It squeaked on, and the Pmal drowned out Babylon’s attempt to intervene:

“In consideration of foregoing evidence, in conjunction with other data not now specified, certain hypotheses may be offered for testing. These have been received or de­duced by me as part of my necessary regimen of rational self-therapy. In this process I was aided by certain other beings, including many TWorlie and the Purchased Person known as Doris—”

“Doris? You?” Babylon interrupted, staring at the girl. Something not human stared back at him out of her eyes, but she only said:

“It is necessary that you receive the data the TWorlie is now offering you.”

“Continuation,” the T’Worlie said sharply, with a burnt- sugar scent for emphasis. “Also assistance from farlink and from the hexagons secured from the wrecked orbital vessel. Central conclusion: Entire ring system, and there­fore existence of object Cuckoo itself, is vulnerable.”

“Vulnerable to what?” Babylon demanded, and the Pur­chased Person reached out to touch him.

With a voice like the tolling of a bell she said, “To de­struction. And all of us with it”

In all the long weeks Babylon had worked with the TWorlie he had never heard so long a monologue—and perhaps not one with such importance for him. For the T’Worlie was saying that he had reasoned out the entire story of Cuckoo! The gentle chirping went on and on, and his Pmal rattled out the translation:

“Hexagon record encoded by ancient historians of early Watcher race purports to summarize their history. State­ment of historians: Race ancestral to Watchers was brought to Cuckoo by, quote—”

The translation from the Pmal stopped short: the T’Wor- lie’s shrill bird song continued, but without translation. Ob­viously there was no equivalent store in the Pinal’s datafile. “Don’t play tricks, Mimmie,” Babylon begged. “What does that mean?”

“Original ambiguous. Analogy with known terms sug­gests tentative translation as ‘eternal master,’ ‘supreme cre­ator,’ or possibly ‘God.’ To continue summary, the original Watcher race was brought aboard before the intergalactic voyage began, to defend Cuckoo. Evolved on a low-G world, they were gigantic winged warriors. The hexagon record seems to imply that the ‘supreme creator’ and most of his slave races were to sleep through a voyage lasting—” Again, all he heard was the TWorlie’s chittering. “Term ap­pears to indicate a time period of extreme duration, cer­tainly tens of millions of years. While others slept, the Watchers were stationed in the orbital forts and at points near the surface of Cuckoo to guard it at least during the first stages of the long voyage. If Cuckoo was created as vehicle of flight from anticipated galactic catastrophe, other beings may have sought to get aboard or even to seize the whole craft in hope of saving themselves.

“The successful emergence of Cuckoo from the endan­gered galaxy into intergalactic space made it safe from any such attacks. During the long ages of flight between galax­ies, no further military service from the Watchers was re­quired. They appear to have been neglected, if not forgot­ten. In the beginning, as the historians imply, no life had existed on the external surface, which was then a bare and sterile metal shell. The water and soil and atmosphere there now seem to have been accumulated through the ages of the flight, partly from collected cosmic dust but largely from waste products discharged to the surface from the in­ternal mechanism of Cuckoo. Plants developed there, per­haps from spores and seed in the vented waste. Animals followed, brought perhaps by the Watcher garrisons or per­haps by escaping slaves of other races. These in turn were followed by degenerate dwarfish Watchers such as those we have encountered, which became predators upon the animals and finally enemies of all they had been intended to defend.

“The rebellion probably began in Watcher crews of the orbital forts. With their original duty forgotten, discipline was gone. The last historian speculates that supplies were interrupted and contact with the masters broken off. The orbital crews may have been forced to forage on the sur­face; perhaps they got a taste for freedom from the outlaw Watchers they met there. Using the advanced technology given them for operation of the orbiter, they discovered vulnerable points in the structure of Cuckoo and planned an attack against it—intending, the historian believes, to extort concessions, not to destroy it completely.”

“Vulnerable?” Babylon shook his head, staring at the hovering TWorlie. “Where?”

“At eight points,” the TWorlie chittered. “The phrase in the record may be rendered as ‘the fatal eight.’ The vulner­ability exists because the position of the central sun is grav- itationally unstable. In order to cancel out accidental drifts, which would be increased by positive gravitational feed­back, supporting rings must be monitored and continually adjusted. This is done through control stations established in each of the eight octants of Cuckoo. Such control is pos­sible because the atomic rings are elastic. Through applied magnetic force, they can be stretched in one octant and shrunk in another, to adjust their distance from the central sun and the consequent gravitational attraction. The eight stations—”

“Those points on the map?” Babylon whispered. “At the center of each octant? The place where we found the wrecked orbiter? And the temple over the lake? Are they the Achilles’ heels?”

“Term ‘Achilles’ not found in Pmal lexicon, and such interruptions are counterproductive.” The TWorlie re­proved him with a sharp ammoniac reek. “Danger to Cuckoo is greater than mere collision. Hexagon record states that application of excessive control force could penetrate electronic sheath and reverse formation processes to break quark chains, disintegrating entire atomic ring into raw en­ergy and supermassive atomic fragments, themselves disin­tegrating. A ring-bomb all around Cuckoo, whose detona­tion would ignite a billion more. The rebel leaders planned to strike at the control network, using stolen technology. They hoped to conceal their actions by use of the tachyonic helmet. The helmet, as described by the author of the hexa­gons, is a device for mental contact through zero-mass tachyons. It was designed by the ‘eternal creator for con­trol of his slaves and communication between them. The rebel Watchers found how to disable the spy circuitry, al­lowing them to use rebuilt helmets for illicit contact with one another, shielded from observation by their former masters.

“Preparing to strike, they obtained plans of the control stations. These are located deep inside the sphere, just above the inmost rings. The control stations are well de­fended, by special slave forces more loyal than the Watch­ers. The rebels knew that any successful attack would re­quire a powerful military force. After long preparation, they diverted the fortress from orbit to land where we found it. The main body of attackers left it there, attempt­ing to force their way down through the levels of Cuckoo to the station.”

“And failed—”

“Clearly.” An indignant chirp. “Details unknown. The plot required complex coordination of many difficult oper­ations. If all had succeeded, Cuckoo would no longer exist. The wreckers were probably unable to seize the station and divert sufficient power to threaten the ring system, but that is merely speculation. The historian remained aboard the wreck with the rebel commanders, waiting for the at­tackers to report possession of the control station and readi­ness to destroy Cuckoo unless the ‘eternal creator’ met their demands. No such reports were ever received. Instead, the wreck was soon surrounded with the electrostatic fortresses through which we passed with such danger. Historian and fellow Watchers remaining on orbiter were never able to leave it. They died there.”

“If the system is impregnable—”

“Erroneous assumption.” A sternly ammoniac breath. “Cuckoo was never impregnable. As you yourself foresaw, knowledge of the hexagons is hazardous. It has brought ex­treme peril upon me. Spy devices were placed in my quar­ters, and copies of my hexagon translations have been re­moved. All Cuckoo is now in danger from some of our own companions, who now know how to strike through those eight fatal points.”


“Identities unknown. However, a deltaform scent was left in my quarters.”

Babylon frowned. “I didn’t know the deltaforms were that suicidal.”

“Comment.” The shrill chitter cut him off. “Allowing death of tachyonic duplicates is not suicidal for originals. Hypothesis: Destruction of Cuckoo may now be attempted by beings who have stolen its secrets and now hope to keep them from others. Evidence indicates that plotters may possess adequate forces and adequate techological sophisti­cation to achieve their objective.” The TWorlie hesitated, then finished strongly:

“This is ethically intolerable to me,” it stated. “Therefore I declare my willingness to participate in this project.”

Babylon could not help himself, he exploded in a burst of laughter. The TWorlie merely hung there, gazing at him with those five bright eyes until Babylon was able to speak. “You couldn’t just say yes, could you?” he asked, wiping his eyes. There were smiles, too, on the face of Pertin and Doc Chimp—one could not expect them, after all, from the other occupants of the room.

But the smiles did not last.

They were already beginning to fade as the people in the room contemplated the significance of the T’Worlie’s long discursion; and then they were wiped away entirely. There was a shudder that rocked the very fabric of the orbiter. They all felt it, and something like a gasp came from each of them. “What happened?” Babylon demanded.

No one answered. Then, after a moment, Doc Chimp whispered, “We’d better find out, Dr. Babylon, because there’s something awfully wrong. The lights are going out.”

The pogrom had failed to meet its goals; some conspira­tors had escaped. The proof was all around them. The orbi- ter’s power had dwindled and died; the lights went out, the gentle, permanent sigh of air circulators whispered to a stop, the standby glow of the stereostage faded to dark.

They were in blackness, and everybody was talking at once; Babylon let go of the wall loop he had been holding, and at once was floating in absolute , darkness, with no up and no down and a terrifying, helpless vertigo. He brushed against something flimsy—the T’Worlie?—and yelped sharply as something metallically sharp raked his arm.

And then there was light. Not much. But a glimmer, and enough to see; Doc Chimp had had the presence of mind to find the door and wrench it open, and the pale emergency lights from the corridor filtered into the room. It was the silver woman’s wingtip that had slashed him, Babylon found, and it was she who took command. Her voice chimed clearly, “There has been an explosion. The damage must be ascertained. Follow me!”

It was easier said than done. She could fly! Panting and swearing to himself as Doc Chimp pulled them along the dim corridors after her and the others, trying to help and more often slowing them down, Babylon was furious at the unfairness of it. Unfair that she had wings, and thus pres­ence of mind! Unfair that these senseless squabblings among hatefully strange beings should endanger him! Un­fair in the first place that he should even be here, so far from the quiet Cambridge laboratories where he belonged …

But the catalog of unfairness was too long. In all these last days and weeks, Jen Babylon had experienced almost nothing that was fair at all.

As they drove through they found the corridors filling with other beings all on the same errand, fast-flying delta- forms and slow, fumbling kitten-shaped creatures, robots and flesh, all together. By the time Doc Chimp and Baby­lon had caught up with the silver girl there was solid infor­mation. There had been an explosion, yes, and a particu­larly damaging one. Somehow someone—a fugitive Boaty- Bit swarm, no doubt—had jammed the tachyon-transport chamber so that incoming shipments rammed into matter already there, and the resulting blast had destroyed it. More than just itself. It had taken out the adjacent main power reserve and the farlink computer; it had shattered walls several tiers away, so that some of the reserved non- terrestrial habitats, with their queer atmospheres, were now open to the general oxygen-bearing air. “At least,” Doc Chimp chattered, his shoe-button eyes darting back and forth at the devastation, “we’ve got one thing to be thank­ful for! The outer hull wasn’t touched—we’re not all trying to swallow vacuum now!”

“Yet,” Ben Pertin snarled, and the chimpanzee’s face became woebegone. For certainly the integrity of the hull meant only a reprieve—a short one at that. Without the constant shipments of food and replacements through the transport chamber, without the steady inflow of energy- dense transuranics for the power chamber, without any of the thousand things the orbiter needed to survive, its life span was short. The air would not circulate, and so in one place they would be gasping for breath, in others burning themselves out on excess oxygen. They could not even ask for help! And if they had, help was forty thousand light- years away …

Or a day or two.

Pertin’s eyes widened suddenly, and he tugged at Baby­lon’s arm, nodded to the others, and drew them all away to a more private part of the dim-lit, strange-smelling tunnels. “We’re going to take a lander,” he announced.

“We’ll never get home in a lander,” Doc Chimp moaned.

“Not back to the Galaxy, you fool! Down to Cuckoo.”

“Oh, of couse, Ben!” cried the chimpanzee, nodding vigorously. “There’s air there, and food—why, we could live a long time. Of course, there’s no way to get back to our real home from there—”

“Shut up, Doc,” Pertin ordered brutally. “We’re not going home—not now, probably not ever. And we’re not going to settle down and start a family, either. We’re going to the temple to meet Zara and Org Rider—and then we’re going inside!”

Doris stirred, and the faraway look in her eyes grew in­tense. “I concur,” she said, “in that plan. What happened here is only a symptom; the cause of these events is within Cuckoo.”

Babylon hesitated. “But Ben,” he began, “somebody must try to repair things here—”

“Somebody will! And maybe they’ll succeed—but I don’t care whether they do or not.” He was both angry and ex­alted, his long, untidy pigtails writhing as his head jerked in excitement. “I’m going to Cuckoo—if you want to come along, follow me. Otherwise stay here and rot!”

They drove through parts of the orbiter where Jen Baby­lon had never been before—where warm-blooded, oxygen- breathing mammals had never been, because the environ­ment was death for them. But now it was not. The explosion had sundered the retaining doors, and the poison atmospheres had been blended with the predominant oxygen-nitrogen mix. Babylon’s heart was wrenched with pity as they passed still forms of methane-breathers and other exotics—and some not so still, queer soft-bodied things like toads made of jelly, gasping piteously as the cor­rosive oxygen destroyed their lungs. “Come on!” Pertin yelled furiously. “You can’t help them! And we’ve got to get to a lander before others think of it!”

In the event, they were not quite that lucky; the first lander berths they came to were empty, and at the nearest that was occupied there was a mob of Sheliaks and kitten- creatures fighting to get in. They passed it by—

And found one ready to go, with no one else near— Or so they thought.

But as Pertin, shouting with triumph, cast himself to­ward its opened lock a dense steel-blue smoke poured out of it, and arranged itself as a shimmering cloak of diamond-bright beings before the hatchway.

Pertin clutched frantically at the wingtip of the silvery girl beside him, swore as his fingers were lacerated, but managed to halt his plunge. “Get out of the way, damn you!” he bellowed.

The shimmering curtain stirred, and the whine of the Boaty-Bits translated itself through their Pmals: “We can­not allow you to enter. You must die with everyone else on the orbiter.”

“Die?” Doc Chimp whimpered. “Die again? Oh, but I’ve died so many times before—please! Don’t make me do it again!”

The curtain rippled gently, almost as if moved by pity. Then the voice came: “Some part of you will live. Some part of all of us will live.”

Pertin hesitated, almost choking with rage, and Jen Baby­lon, clinging to the lander-chamber wall, wondered des­perately if it would come to an attempt to brush through the shimmering cloak. Could such tiny beings really harm them? Was there any strength behind their commands?

He did not need to find out, for the silvery girl cast Pertin aside, spread her wings, and, hovering in midair, raised her hands toward the fugitive Boaty-Bit swarm. “Live if you can!” she cried. From her fingertips a flood of white-hot energy leaped out at the collective beings, cutting great swaths through the swarm; and again, and again, un­til only a few scattered individuals fled aimlessly away.

Babylon barely remembered hurling himself toward the lander after Pertin and the winged girl, thrust in by Doc Chimp, followed by the TWorlie.

Then there was a gentle tremor, and they were free, out in space.

As the thrust of the lander’s motors began to move them away and down toward the immense, glowing object be­neath them Babylon struggled to a port to look back at the orbiter.

The great, strange creation was dead. The aura that usually hung about its communications antennae was ab­sent; the lights from its ports were dark. All the visible signs of functioning had stopped.

But they were on their way.

Although Jen Babylon had never before seen the temple with his own eyes, he recognized it at once. What was dif­ferent was the lake. There was no lake. There was only a shallow bed where once a lake had been, and, on the greensward between the caked orange mud and the jungle that embraced it all, half a dozen terrible and strange winged creatures, with tall, lean human figures moving among them. Zara Doy came running to the lander. “We were worried about you!” she called, peering anxiously at the figures as they came out. Pertin explained about the explosion and the fact that they had had to come by slow landing craft instead of the near-instant tachyon transport … but Babylon wasn’t listening. He was staring at the great creatures that squatted placidly on the margin of the dry lake. Their bodies were glittering bronze, their tails and the tips of their stubby wings shading to silver, as they moved they opened huge red mouths with sharklike teeth.

They did not look like creatures he wanted to be so close to.

Org Rider, grinning, came over to reassure him. “They’re perfectly trained,” he boasted. “They won’t hurt you—as long as their owners are around. This org is mine, Babe Junior; the little one off by itself is Zara’s. We can each take one of you, but I brought some friends along—I hope there aren’t more than seven of you,” he added, peer­ing anxiously toward the lander. “Because it’s better if we don’t put more than two on each org.” Reassured, he intro­duced the other riders, every one as skinny and as im­mensely tall as Zara and Org Rider themselves. The names escaped Babylon; his attention was all on the orgs them­selves. Ride those creatures? With those great savage teeth so near? Especially when, Org Rider pointed out, each steed was “tamed” only in respect to its own individual rider, and if anything happened to the rider it would have to be considered as ferocious and as wild as any leopard or grizzly bear.

But once up on the creature’s back, behind the graying, bearded old man named Wingsmith—a cousin of Org Rider’s mother, he had been told—Babylon began to revise his opinions. The stubby wings were marvelously flexible. The broad back was warm and comforting beneath him. The org responded to every wish of Wingsmith as if the two were part of the same compound creature; the nine winged dragons all sprang into the air at once and circled the dry lake bed—Doc Chimp with Zara, Pertin behind Org Rider, Babylon, Redlaw, Doris with other riders from the tribe. There were two other orgs, but the winged silver girl and the TWorlie disdained them; the extra orgs were given the packed supplies and equipment.

“All ready?” Org Rider cried, nodded at the answer, and led the way.

In single file they plunged down toward the ancient doorway and flew steadily into the interior of Cuckoo.

The TWorlie could not keep up. It folded its filmy wings and hung on to the tail of Org Rider’s mount, its tiny weight not even noticed by the powerful org. But its pres­ence was essential. As they traced the convolutions of the tunnels they found themselves in a maze. A labyrinth; they would have been hopelessly lost in the first hour but for the T’Worlie. Its patient, supple mind had perceived the need for directions, and it had stored every scrap of data from the camera Doc Chimp had carried, from the glimpses obtained from the helmet, and from every other source, meticulously organizing them into a sort of strip map of the passages. When there was doubt, the TWorlie supplied the answer. He had even plotted a route around the blocked stretch of tunnel that had defeated Te’ehala Tupaia; and they raced through the bowels of the immense artifact, down and down.

Babylon, hunched behind the gray-bearded rider, tried to count the number of days since his world had been stable and safe. It could not be more than a few weeks, but it seemed that since the beginning of time he had been thrust from one terrifying and unbelievable situation into another. His senses were saturated; his capacity for wonderment and even fear was almost exhausted. They sped through broad corridors and narrow, some so tight that Babylon could scarce believe the orgs were able to fly; they crossed immense flat spaces, with broad checkerboarded fields be­low them and ribbed metal ceilings above, the orgs uner­ringly darting between slender support columns. From time to time they saw traces of the party that had trudged these corridors before them—a discarded food packet, castoff bits of equipment. They stopped in one of the broad areas of growing things so that the orgs could forage and the riders take a break. The ceiling above them shone softly, and there was a steady drainage of chilled air that made Babylon shiver uncomfortably. He did not dare to eat the strange, soft-shelled nutlike things that grew on the land, and the machine-made food in the rations they had brought had a reek that took away his appetite. He was glad enough to be moving on—

And then they came to a sign of the party before them that was different from all the others. It was the body of a white-haired man. He had died with an expression of terror on his face, and the entire front of his torso had been ripped open.

The orgs halted while their riders stared down at the corpse. “Oh, I know what did that,” Doc Chimp moaned. “It’s that Watcher! The same one that killed me!” And his shoe-button eyes darted fearfully around, as if he were ex­pecting the maddened being to plunge out at them from any niche or tunnel.

That was the first of the corpses. It was not the last. Less than a hundred meters farther there were two others, then another single body—

And then the passage they were flying through opened into an immense cavern, filled with machines and conduits and huge, strange devices of many sorts, and Babylon found his capacity for startlement suddenly born again. “I know this place!” he cried.

“Of course,” called Zara from the org beside him. “We saw it on Doc’s camera!”

“No, no!” Babylon stared around, wondering. “I’m sure! I’ve seen it in a dream! Those glowing walls. Those bright spots that look like jewels, only they’re glowing. Only— only I remember seeing those broken beams, and ugly glass crabs swarming over them trying to fix them—” He paused, trying to sort out dream from what he had seen in the stereostage or via the helmet. He shook his head. “Something terrible happened here,” he said positively, “and I dreamed about this place even before it happened!”

The other orgs were dancing around, and Redlaw, who had gone ahead out over the great terrifying void, returned to boom: “Terrible enough, Babylon. Look down there!”

At the base of the vertical drop there was a cluster of forms. The orgs swooped down dizzyingly, and they ap­proached carefully.

But there was nothing to fear from the creatures at the bottom. They were all dead, humans and one which was not human. “The Watcher!” Doc Chimp chattered in ter­ror. “Oh, that’s the one that killed me! Please, Dr. Baby­lon—Ben—Zara—please, let’s get away from here!”

“It’s dead, Doc,” Zara said soothingly, gazing down at the hideous creature, shrouded in what was left of its im­mense leathery wings. Its body was ripped and torn, and next to it were other bodies. A huge, golden-skinned man whom Babylon recognized with a sharp intake of breath— the Purchased Person he had seen way back in Boston, in the Tachyon Transport Base. And another more startling still.

“Why, it looks like that old man we saw already!” Zara gasped. “Only—only he’s been changed—”

“Edited,” Ben Pertin snapped “Reduced in size. Tough­ened, to stand this place when it was still bursting open. Changed in a lot of other ways, no doubt … But dead,” he finished, almost with satisfaction, as he gazed down at the gnomelike shape. “No sense in standing around and gaping—let’s get on with it!” And he tapped Org Rider’s shoulder, and they spun away.

A scattering of the glassy, crablike creatures still worked at the machines in that great chamber, but they paid no attention to the orgs or their passengers. The party entered another passage, and another, and another—

Babylon lost count of how many tunnels and galleries and caverns they traversed, even of how many times they stopped for food or rest. They flew through a featureless space to a pale gray rectangle that opened up to become the mouth of a vast metal tunnel; they passed side passages and openings that he did not bother even to glance into. They flew down a sloping tunnel with a queerly triangular cross section, the walls joining in a peak over their heads, with what looked like a shifting surface of moving cinders under their passage; he did not care. They crossed a mossy plain with the ceiling above dark and so high that they could barely see it, and when they entered the next tunnel, narrower and darker than the others, the first orgs shied away from new bodies on the floor—more of the gnome­like travesties of Purchased People, Babylon saw as they passed, and hardly cared that he saw.

He lost all sense of distance and of time. He was half drowsing when he realized that all the orgs had stopped, and their riders were dismounting.

“What’s going on?” he asked, and Doc Chimp whispered in alarm:

“Not so loud, please, Dr. Babylon! They’re very close now—Zara said she heard voices!”

Babylon stared around. They were in another down- sloping passage, this one brighter than most, for at the far end of it there was a queer radiance. He listened, but heard nothing, and wondered whether it had been Zara’s imagina­tion rather than a voice—

No. There was something. More a drum rattle than a human voice—a Scorpian robot! Very distant and very faint, but there was no doubt.

“I think we’d best leave the orgs here,” Redlaw said, as softly as his deep voice could be made to sound. “Maybe the T’Worlie could go ahead and scout for us—”

But the T’Worlie did not at once obey. It hung in mid­air, its filmy wings moving slowly as the longest-range of its five patterned eyes peered ahead of them. The TWorlie were almost never agitated, but there was something shaky in its shrill whistle as it spoke: “Statement: Person or per­sons approaching rapidly. Recommendation: Caution. Fur­ther statement—”

And then it fell silent for a moment, hovering … and then, in a manner most unTWorlielike, it whistled rag­gedly, “Also coming— Not physically coming— Immi­nently approaching—”

And then it did something no T’Worlie had ever done in the presence of a member of another race. It screamed.

The Pmals could find no comprehensible translation, and did not try. They simply reproduced the whistling, warbling sound of terror; and broke off when the T’Worlie collapsed upon itself, its five eyes staring emptily, its wings in helter-skelter disarray, and slowly, slowly settled to the floor of the corridor.

There was a time, and not long in coming, when Jen Babylon comprehended all things at once, with a terrible knowledge that hurled huger and newer questions at him … but that time had not yet arrived. To Jen, the next few moments were utter, anarchic madness. Everything seemed to happen at once. Even while the Pmals were pouring the T’Worlie’s scream of horror and disbelief into his ears, there were two other sounds. Doris, the Purchased Per­son—she was screaming, too, if you could call the low, ec­static moan that came from her hps a scream. Her face was rapt, her eyes blazing with an emotion Babylon could not read—

And at the same time—

The silver girl lifted herself on her great wings and hurled herself at Babylon. She too was screaming, but words emerged from the Pmal: “A force! I perceive a new concentration of energies!” She collided with him, thrust something into his hands—

And at the same time—

Two figures burst out of the tunnel, one tinier than the other but both inhumanly short. They stopped abruptly as they caught sight of the org-riding group, but then the smallest of them cried out and came on, throwing itself at Zara Doy, wrapping his arms around her knees with a heartrending shout of Mama—

And at the same time—

The noise from the end of the corridor rose to a great rapturous shout—

And at the same time—

The thing in Jen Babylon’s hands reached out with im­palpable tendrils and caught at his mind. It was the helmet. He knew that. He knew, too, that there was a surge of rawly horrifying energy coming from it that threatened to sweep him away through its mere touch, that would surely change him irrevocably and forever if he did not release it at once.

But he could not.

His arms had a life of their own. They lifted the helmet and settled it on his head.

And Jen Babylon’s world changed forever.

There was a part of Jen Babylon that did not change. It merely—increased. That part of him was able to see the tiny figure that flung itself at Zara Doy and recognize it— grievously squashed, distorted, and hideous, it was never­theless the little boy he had seen, an eternity ago, with that other Zara Doy in the Tachyon Base. That part of him was able to feel the rake of the silver girl’s wingtips as she con­vulsively struggled against whatever had her in its grip, ob­serve the lustrous gleam of her almost human body, feel its inhuman cold and rigidity. That part of him felt pain. But that part of him was now submerged in a larger self, as if a color-blind man were suddenly seeing a rainbow, a tone- deaf man hearing music; as if fingers that had never touched anything but themselves now reached out to palp a world.

Like that—but more than that. There were no words. The truth was something for which words did not exist! There could be only analogies and approximations; and the closest words could come to truth was to say that Jen Babylon, all of him, was exploding. Was both the Ground Zero and the infinitely expanding wavefront that was the blast itself.

But that was metaphor. For the reality there were no words.

There were no words to say how, as he exploded past tunnel walls and caverns, past the inner shell of Cuckoo, past every material object within its gravitational range, he reached and tasted each of its myriad creatures, and each of its myriad, myriad atoms.

There were no words to describe how he felt each feeling those beings felt, Doc Chimp’s quivering horror, Zara’s ter­rible blend of horror and love as she enfolded the carica­ture of her son, David’s panicked longing, the raw emo­tions of Ben Pertin and Te’ehala Tupaia, of Redlaw and the battered, semiconscious TWorlie, of Org Rider and even of the orgs themselves.

There were no words to convey the billion-piece sym­phony of tastes and feelings that he sampled from the countless denizens of Cuckoo’s shell, demented Watchers and sullen savages, of a thousand shapes and a thousand million states of mind.

There were no words to convey the sight that opened up before him, the great skeletal shell of Cuckoo itself, and within its curved embrace the restlessly seething auroras of plasma, the distant, bright sun, the immensity spanned by this wall around a star.

And there were, finally, no words to say what he felt when he knew that he was not alone. That even this im­mense new being was tiny beside its neighbor, newborn and unsuspected; that he was naked in the awful presence of ONE far greater than himself.


And now my mission is near its end, for HE is wak­ing.

The great machine stirs in all its hidden places, and re­ports to me. Even the parts that have lain silent for all the thousands of centuries now are commanded to life, and they respond. The desecrators who forced the new intru­sion into HIS sacred fabric have been dealt with, and once more the masterwork that is HIS body has proven invulner­able, even to nuclear attack. As HE constructed it to be.

Now at last HIS vast design fulfills itself.

The guardians of the frozen crypts move and wake, and send out their sensors. First to their organic charges: Are they safe? Have any suffered damage? Need they clone new samples for the store? Then they reach out to HIM for instructions. There are none yet. But they will not be long in coming.

The custodians of the great driving jets at the poles wake. They check their plasma reserves and test their power charges and their controls. It is not yet time for them, but they are ready. When they are needed they will guide our great machine-egg into its fresh galactic nest.

And I am ready—ready to end the long, lonely watch over the great round machine and all its myriad tenants and parts.

I reach out to all my sleeping members. They have rested, blind and uncaring, in the bubbles of a thousand separate memory stores, for the thousands and thousands of years since they were themselves alive, before they be­came, like me, charged particles dancing about the inter­faces of the immense machine.

Was I once, like them, alive? I cannot remember.

But they were! And what things they were, back in the home galaxy, before HE was born out of the need to flee its fires. Great gray starfish from the ammonia slime of seas that never saw their sun. Ethereal wisps of gas clouds that needed no star. Creatures like insects and creatures like rocks, creatures of all shapes and chemistries; crea­tures that were old when HE was only a theory, and crea­tines that HE planned and bred and nursed to ripeness in a spiral arm, even when the galactic core was exploding and the central stars were being devoured by the tens of mil­lions.

And then they, too, were devoured …

As I am about to be devoured …

For HE is awake now, and come into HIS glory, and I—I cease to exist—



HE WOKE. And all over the Galaxy, the shape of the worlds changed for the beings who inhabited them.

In Boston, on old Earth, a man in a red jumpsuit was overseeing the receipt of a valuable cargo of spices and fragrances from a planet in the constellation Canes Vena- tici when there was a sudden eruption of noise. The doors of the tachyon chamber crashed open. The militia on guard duty were borne back on a flood of glassy crab-creatures, their claws rattling like cast dice on the terrazzo floor. “But you are interfering with a priority shipment!” the man cried. They did not heed. They swept over him. Glassy pincers caught at the tuning controls. The slow creep of goods on the conveyor belt halted. Then the tach­yon chamber clouded over with a smoke—a fog—a cloud of tiny creatures, and the swarm buzzed out, dancing like midges over a muddy creek. And another swarm. And an­other. “Why, you’re Boaty-Bits,” the man cried in exasper­ation. “You have no right here! Stop this at once!” But the swarms coalesced and danced toward him, diamond dust sprinkling the air. In a moment the man was covered with them, like a circus clown hit with a flour bomb. He stood rigid and helpless as the swarms came on, and came on, and came.

In another part of Boston, the Crystal Maid knew her destiny had come. She was not truly a she, or even an it, but merely a part of a great dispersed whole, once a star- borne seed, edited to ease her freedom of movement as she led the other seeds on this new colony world. She had no personality, nor even self. But she knew her task. She stood raptly at the edge of the Common, listening with all her senses to the mind-song of the sprouted seeds as they scut­tled across the face of this world. She gave thanks to the distant, deeper drone of that greatest mind whose servants had planned her, and created her, and dispatched her on her way. Beside her, the autochthon Tupaia, temporary ally, discarded tool, cried out in astonishment; she paid no heed. The song of a million seeds on a hundred million worlds flowed through her. She was in touch with the infi­nite. She was the infinite.

In Lawrence, Kansas, on the same unimportant world, it was harvest time at the catfish farms. But when the work­ers arrived with their nets, the things that splashed out at them from the ponds were not whiskered and filmed, but huge, crystalline, clawed—and very numerous.

Very nearby, in the city of Tokyo, Japan—only half a world away—a frantic man named Kazuo Noritamo reached the 80-meter level in the great tower. It was being evacuated—heaven knew why—and the observation deck was crowded with frightened tourists hurrying down. Nori­tamo knew better. Down was where the danger was. He peered through the slanted panes, at the people around the amusements and rides, forty young girls in blue cloche hats with gold bands, a fat bald monk chanting into his begging bowl. They had not yet panicked. But they would. He ran up the steps to the high-speed elevator; no one was there; he got in and pushed the button himself, panting with both exertion and fear. The 250-meter level was deserted. He ran to the window, for once careless of the dizzying height. In the temple grounds at the base of the tower, white- capped police were trying vainly to stem the oncoming march of the glassy crabs, their shells streaked with the oily waters of Tokyo Bay; the police batons did not stop the crabs, did not seem even to annoy them. They were com­ing. He was trapped. There was simply nowhere to go. He was alone at the top of the tower, and as he peered down he saw that the enemy was close. The foreshortened tiny figures on the roof below were now still as statues in a sculpture court, every one of them suddenly limned with a steel-blue frosting of metallic dust, all faces raptly up­turned to the sky, or to him. The rattle of the elevator door behind him made him turn, glad for the company of an­other escaped human. —It was not that. A dazzling cloud of steel-bright motes boiled out of the opening door to show that he had not escaped after all.

On the flimsy moon of a gas-giant planet—still very near; less than a hundred light-years away—a colony of collective beings felt the pulse of the Overmind. They were not like bees, nor even like any insect; they were not even related to the Boaty-Bits, nor had they become a part of the galactic congress of races, since their planet had been missed. But they were bioluminescent aerophytes, tough- walled hydrogen bladders cemented together in floating clouds a kilometer thick. They did not fear the pulse of rapture. It was the destiny that they had never expected, but recognized and accepted at once. They welcomed it.

In the slushy seas of an ice planet, a creature like a pale, lean whale felt the shock of an amputation. He was the owner of a Purchased Person on Sun One. His creature had been stolen without warning. He burst from his pearly home in the sea-bottom sludge and drove straight up, twenty kilometers and more, to breach the surface and leap into the dense, chill air. It was no use. His panic was justi­fied. Out of a great lens-shaped cloud of luminous violet, three crystal creatures in the shape of deltaforms dove to­ward him like javelins. The creature saw them coming and dived to escape, but they followed, as fast in water as in air, and as sure. There was no escape.

On a damp, hot world in a distant spiral arm, three great flying creatures, soaring between a halogen-enriched pink cloud and an angry, oily, scarlet-glowing sea, dodged sav­age strokes of lightning. They did not fear the lightning as much as they feared the winged crystal shapes that steadi­ly, remorselessly pursued … and always gained.

On a small planet under two ruddy suns, a creature that looked like a headless centaur was operating a compact ex­cavator. He was almost alone. Most of his crew had drifted away, part of that epidemic folly that had transformed so many of his race to idlers—his race did not call them “Kooks.” It did not matter much, because the excavation here was easy enough. The surface was a coarse, dark sand., very promising for the minerals that fed his kind. He cut through a wiry gray mosslike growth that bore tiny, powdery flowers of crystal and set out his arrays. A core drill brought up samples of the dark sand. Seismographs probed for deeper data. A tiny antenna, unfolding like an inverted parasol, transmitted the data to his people’s cen­tral store. It was all going well, until his assistants came back, the faceted patches that served them for eyes alight with a sudden rapture, their forms surrounded by a dusting of diamond-bright tiny collective creatures that rose and swarmed toward him.

On the TWorlie planet Nglinn, one of the greatest and oldest of T’Worlie scientists, danced away from his instru­ments with a sharp turpentine-and-lemon scent of joy. For half a long TWorlie lifetime he had sought to find a zero- mass tachyon, the particle whose predicted properties of­fered an immense new range of communication and trans­port—in vain. But now the search was over! Without warning his instruments registered a sudden flood of them, in the trillions of trillions, the strongest pulse they could count! He spun to his stereostage to inform his assistants. They did not answer at first—and when they did the oldest and best of them, all five eyes glowing with an unfamiliar ecstasy, cried out in the compact TWorlie language a sin­gle word. The nearest English equivalent would be: “HE is come!”

And the rapture overspread the Galaxy.

It reached tiny planets and huge, hot worlds and cold, the creatures that lived in slow, sullen dust clouds in the wake of exploded supernovas and in the chromospheres of stars. It reached and possessed a conjugating mass of She­liaks in the depths of their home planet, and transformed them; it was spelled out in drumbeats on the stark, dry world of the Scorpians. It did not affect every world, but most. It did not strike every individual, or even the major­ity. But hardly a race failed to find some of its members seized with the passionate touch of an Overmind, or to feel the grip of tiny collective beings swarming out of their tachyon stations, or to retreat in the face of the armies of crystal creatures that boiled from their seas.

And far from the Galaxy, in the shell of Cuckoo, a strange battle raged, as the exploding self that had once been Jen Babylon, with his million eyes and his infinite array of senses, confronted the Titan who had swallowed one galaxy and was ready for another.

The contest was not equal. But there was at least a con­test, and HE had never known one before—until the battle for the billion worlds was joined.


Dr. Jensen Babylon slowly raised the supple helmet from his head and looked about him. He was standing on a shell of hard, dark crystal, and far beneath him a sun hung in a glowing cloud of plasma, tiny and remote. Its fire was filtered by that dark crystal floor, so that he could see its sharp-rimmed disk, a little smaller than Sol’s, pocked with twin, diverging rows of small, dark sunspots.

Nearer to hand were the trashed and reeking remnants of the struggle that had come before. The dark crystal was smeared with blood. The hot air bore a slaughterhouse stench of alien chemistries in destruction. The carnage went all the way to the far wall, bodies, bits of equipment, a great translucent object surrounded by corpses.

“Dr. Babylon,” whispered a small voice in his ear. “Jen! What has happened to you?”

Babylon turned and saw Doc Chimp, arms wrapped around a gaunt steel pillar, just behind him. The black shoe-button eyes were not fearful but they were wondering. Wondering as they stared at Jen, wondering as they flicked to the corpses, as they fastened on the distant discarded rubble. “I don’t know, Doc,” Babylon said simply. “I’m dif­ferent.”

“Is it that helmet? Has it—done something to you?”

Babylon nodded, gazing around. A titanic battle had been fought here, and the overpowering beetle stink of Watchers told what one side had been. The other, perhaps those shattered crystal crustaceanlike things, their bodies mixed in with the hard-armored corpses of the Watchers themselves. “It’s more than the helmet, Doc,” he said som­berly. “I don’t know what it is, but I can see things that were hidden before, and what I can see most clearly—” He hesitated and frowned. “I see that the greatest is yet to come,” he finished. “We are in the presence of something very large.”

A slow twittering from his other side told him the T’Worlie was still there, too. “Concurrence,” it chirped, tone solemn. “Hypothesis: Presence is central conscious­ness of Cuckoo.”

There was a gasp from Doc Chimp, and a quick, muf­fled exchange between him and the T’Worlie. Babylon hardly heard them. He was immersed in the wonder of his new knowledge. Taking the hood off had not taken away his immense new persona. Its forces had changed him, and he knew that the change was forever. He could hear Doc Chimp and the T’Worlie. He could see the laser-seared and dismembered bodies that lay about. He was aware that the little ape had said something very important, and then bounded away.

But his attention was taken up by the enormous, ex­panded perceptions that surrounded him.

He knew that something vastly important was about to happen, very soon. Yet he was not anxious or apprehen­sive. The forces that had expanded him had also made him hugely more quick; and so there was time.

There was time for him to perceive what lay about him. He saw that not all the motionless crystal crabs were de­stroyed; many of them were” crushed and broken, but far the greater number were simply frozen, waiting for orders from that being who owned them. He saw that there were other players in this great drama, and all of them, too, still waiting for their cues. He saw the battered Scorpian robot that lay crushed and immobile halfway along the trail of carnage, rattling helplessly to itself in a complaining grum­ble. He saw Zara Doy, with the kobold boy clutched fiercely to her breast, staring up at him in fear and hope, and the weary orgs that waited impatiently to be fed or ridden or set free. He saw a cloud of Boaty-Bits that danced in a dense swarm, waiting for the will of their mas­ter; and everything he saw interlocked with all the rest. He perceived the patterns and the roots. He did not only see. He comprehended. Far away he saw a bounding figure, tiny as a flea in the distance, and knew that it was Doc Chimp following the trail of destruction—and knew what errand he was on.

And urgent as all that was, he took time to wonder at the whole mystery of Cuckoo,- now revealed to him entire. Not merely an artifact. A machine. Powered by hydrogen fusing into helium at the core of its sun; the energies turned into radiation, then trapped and redirected by the structures on the interior of its shell. Stellar energy fed those huge devices at the poles, ion-thrusters that had hurled Cuckoo out of its home galaxy and would halt it at its destination. Stellar energy cooled the great ice caves where frozen bits of organic matter slept, waiting to be thawed and born again to populate new planets in the new starcloud. Stellar energy powered the great machine-mind that had overseen the workings of Cuckoo while its master slept, that had sent emissaries to all the planets of the new galaxy and sampled all its worlds—and was now silent. Stellar energy had powered those great, eternal monatomic rings, so that their centrifugal force held the great shell suspended and prevented it from collapsing into its central sun. All this Jen Babylon saw and understood.

And, out of nowhere or out of the air around him, sourceless and irresistible, a great voice sounded in his ear: “now you know almost all.”

He turned, and froze. The cluster of Boaty-Bits had shaped themselves into a huge, winged, three-eyed form, facing him, while another cloud of them danced toward him. As they settled on his body, his face, his eyes, the voice spoke again: “now know me.”

And he knew, and the pain of that terrible knowledge was almost too much to bear.

A galaxy far away—a little older than the one that shel­tered Earth. Not very different. Not different in the way in

which all galaxies were alike, for it was destroying itself.

All galaxies destroy themselves in the end, because the random movement of mass sooner or later produces con­centrations at the core. A sort of critical mass. A knot in space-time. Sometimes it is called a black hole, sometimes a Seyfert galaxy; there are countless millions of them in the sky, and each one is the agony of a billion suns.

Within that far-away galaxy were myriad inhabited worlds, old and wise or still straining toward the awakening of intelligence. All doomed; but in some of them, the oldest and wisest few, the knowledge of that doom came to exist.

They were very wise, and they had time. The frightful fires at the core of their galaxy reached out toward all its worlds—but slowly, no faster than the crawl of light it­self—while they had the tachyons to reach around to all their worlds, and in time the zero-mass tachyons. For a tachyon is brother to the photon. The closer to the speed of light it travels, the more its mass. The less its mass, the farther from c its velocity. For a zero-mass photon, there is no energy, no motion. But for a zero-mass tachyon … the speed is infinite.

So they reached out to the neighboring galaxies to find a haven. They built an ark to flee in. And they peopled the ark. Specimens of every sapient race, frozen in liquid-helium baths to be revived when there were safe homes for them again. Memories of all the collective wisdom of their cultures, organized into a vast computer store, to ran the ark and protect it. Those were the passengers and the crew. And for the captain …

For the captain they planned and bred a race that could free itself from flesh and live on; that could fuse and take into itself all of the other intelligences of the galaxy and make use of them; that could rest for” many millennia, and then awaken again to carry out their plan.

And then, as the deadly radiation flooded over their homes, they died … or died in some parts of themselves, while other parts lived on—

In HIM. And the great ark, or egg, was launched on its immense journey.

And all this Jen Babylon knew, and then the steel-blue creatures fell away from him, and he could see again with his own eyes, and the vast voice spoke once more:

“now you know me. now know what you must en­dure.”

And Jen Babylon, with all the strength he owned, shouted:


There was a pause, while the dense swarm of Boaty-Bits moved about within the confines of the shape they had assumed, and the galactic beings drew back, terrified spec­tators at the huge debate. Then the Overmind spoke:

“you must. i do not come to conquer, but to save. your galaxy too is doomed, and already the fires are flashing at its core.”

And the images flooded into Babylon’s mind, of the vast press of matter at the heart of his own Galaxy, now inexor­ably beginning its long, irresistible explosion. That which was human in Jen Babylon was terrified, as much by the insupportable feeling of responsibility as by the frightening knowledge itself. Yet he did not let the fear overcome him. Steadfastly he cried:

“Even so—no!”

And the battle for the billion worlds was joined.


In the great contest, the being that had once been Jen Babylon had only very limited assets. He was a fusion of many beings, but the fusion was incomplete; while the Ov­ermind that stood against him was a synthesis of thousands of billions. HE needed no allies. Babylon might have needed many, but had only two: a troubled T’Worlie and a terrified ape.

The Superbeing was very old, and quite unused to being denied HIS own way. HE had been created for the specific purpose of absorbing lesser beings into HIMSELF. There was no opposition. In the first instance, it had been the lesser beings themselves who created the first crude, tiny prototype of the Overmind, for the immense destruction at the core of their galaxy gave them no other hope to sur­vive. Later there was the example of the thousand earlier races who had let themselves be swallowed into HIS maj­esty—sometimes with joy. More often not; but the spur of the explosion at their galaxy’s heart had always been enough. So it had been easy for HIM. It had at the last become routine. As the plan progressed and the ark was being prepared, new races reached intelligence, or were discovered, or found their own way into the galactic inter­change; and then HE would choose a member of that race to answer for all, give him the knowledge of what was and what was to be—and accept them into HIMSELF. There had never been any resistance—how could there be?

But now, unbelievably, there was!

For Jen Babylon, and all the parts that made up the huger Jen Babylon, were born of a galactic culture that

recognized individual differences and even prized them. Babylon was not merely struggling for the physical safety of his galaxy, but for its soul.

It was a matter of right! The right of Jen Babylon to choose his own field of study, and select his own way of life; of Te’ehala Tupaia to sacrifice himself on the altar of an ideal; of Doc Chimp to allow himself to be killed, and killed again, and still cling to existence. The force that fed Babylon was the total of the rights of even those who de­nied those rights, the Boaty-Bits and the Sheliaks; of the TWorlie and the Watchers and all the myriad unnamed galactic peoples; of the Zaras and the Davids, and Org Riders, and both Jen Babylons and both Tupaias, and the countless Ben Pertins and Doc Chimps—

For they each and all had a right and a built-in direc­tive: to carry on their lives. To do the thing most important to any living thing: to live.

They were not in any way sacred, not even to each other. Not even to themselves. Time and again, the races of the Galaxy had often destroyed each other. Certainly they had worked at cross-purposes. Each had moved on its own trajectory, with all their myriad myriad problems and con­frontations and prejudices and hopes each tugging them in a different direction.

But, over time, there was always a sort of vector effect that summed the individual impassioned drives. Slowly, slowly, with many backtrackings and countless.hesitations, the life of all those beings slowly became—not happier, not more successful, not more comfortable— But more meaningful.

The purpose of life, one of his professors had once told Jen Babylon, is to learn the purpose of life.

And it was now Jen Babylon’s task to allow that purpose to be carried out.

Babylon, the physical, mortal Babylon, sighed deeply, raised his head, and confronted the Superbeing. He said steadily, ‘Tell me what you want.”

to save you. to take into ourself every sentient * our galaxy.”

“That,” Babylon cried, “you may not do! We don’t want to be parts of a collective intelligence! We are individuals, and we mean to stay that way!”

“untrue. only partly true.”

“I grant,” Babylon said desperately, “that there are ex­ceptions—the collective intelligences, like the Boaty-Bits. But they are our horrible example! Because they are col­lective, they stopped evolving long and long ago—while the rest of us continued to grow! It is conflict—the conflict of ideas and goals—that brings progress!”

“it brings destruction.”

“Yes,” Babylon agreed, “sometimes it brings that, too. But that is our choice. We will not permit you to devour us.”

Silence, while the Great Being pondered this new fact of resistance and Babylon stole a covert look across the vast chamber. The distant figure of Doc Chimp, which had bounded so swiftly away, was toiling laboriously back, and it carried something softly gleaming, and bigger than Doc himself.

Something flashed before Babylon’s eyes, filmy and bright-colored; it hung before him with its five bright eyes peering into his. It chirped frantically: “Dr. Babylon! You must not!”

“I must,” said Babylon, reaching out with clumsy sym­pathy to the TWorlie; but it shrieked in agony, like a ca­nary on the rack, and fluttered clumsily away.

The shape of whirling bits stirred restlessly and the Great Being spoke: “you have no choice,” it said reason­ably, and Babylon shook his head.

“Neither of us has a choice,” he pointed out. “I deny you the right to absorb us into yourself! And I warn you that if you try, it will be the end of you.”

“that is not possible. you are weak. i am strong.”

“It is your strength that will destroy you,” Babylon said wearily, turning to gaze at Doc Chimp, toiling nearer with the great, murderous weapon in the form of a translucent block that had come—so long ago!—from the wrecked ship. “You see,” he said, stretching and gazing down at the distant sun, “we know where we are. This is one of your octant control centers. If my primate friend there fires that weapon it will knock out your controls. That electronic sheath will break down, and how long will it be then before one of your atomic rings disintegrates? And after that—”

He shrugged. He did not need to say any more. The TWorlie had spelled it all out, and surely this immense mind would not need to have it repeated. He gazed regret­fully at Mimmie, who was stricken with horror at what was going on. Somehow the TWorlie would have to be made well again … Somehow something must be done to re­pair the damaged lives all around him, the grotesque child that Zara Doy was clutching to her, the agonies that they had all suffered … Somehow … Something.

But what? What could make all this suffering worth­while?

“Freedom,” he said aloud, and turned again to the clus­tered shape that confronted him. “You see, it’s a standoff. If you don’t leave us alone you will be destroyed yourself.”

The silence protracted itself, and then the Great Being spoke—its voice slower than before, almost hesitant, “your galaxy is doomed,” it protested.

“No!” Babylon said sharply. “It is in danger, but it is not doomed. You failed to control the explosion in the core of your own galaxy, but we will not fail. We will find a way to contain the explosion.”

Pause. Then, “how?”

Babylon cried angrily, “I don’t know how; I only know that there must be a way. Somehow! Maybe a super-Dyson sphere, enclosing the core—”

“such technology does not exist.”

“Of course not! Not yet! But it can. I know that no race in the galaxy has the structural materials or the engineer­ing skill—they’re both orders of magnitude beyond any­thing that has ever been attempted. But they are not im­possible! And we have time! Thousands of years at least! Especially … especially if we work together.” And when Babylon had said that he stopped. He had said it all. The decision was no longer his.

The silence was longest of all, while Doc Chimp stood firm but fearful at the keyboard of the strange weapon, skinny arms poised like the mad organist under Notre Dame, while all the other beings waited—while a galaxy waited.

And at last the Superbeing spoke.

“i do not know if it is possible. but it is true that there is time.”

There was an unheard sound, like a great worldwide sigh. Babylon pressed his advantage: “And you’ll let us do it? You’ll release the Kooks and let them return to normal life? Withdraw your slave machines from the galaxy?”

“i will.”

“And we’ll try to build a wall around the core together?”

“we will.”

“And when it’s done—”

“when it’s done- “

“You will leave us alone?”

“no. will make copies. will take copies. will leave originals.”

Babylon thought hard. Take copies?

He said slowly, “And then you will leave our galaxy for­ever?”

“forever. with copies.”

Babylon nodded. Ten thousand years at least, maybe more. Time in which great changes could occur.

“All right,’ he said, “we have agreed. You will help us try to contain the core. Whether it succeeds or fails, you will then go on to another galaxy, making copies of every intelligence in our galaxy and taking them into your­self …”

And he did not add:

If you can.
