Between the Strokes of Night

by Charles Sheffield

  No, Peron had said promptly. But then his conscience had troubled him, and he told Elissa the truth. He and Sabrina had been very close for two years, until he had to devote all his time to preparation for the trials. Then she had found someone else.

  Elissa didn’t bother to disguise her satisfaction. She had quietly taken hold of Peron and begun to make love to him.

  “I told you I was pushy,” she said. “And you were acting as though you’d never get round to it. Come on — unless you don’t want me? I’ve wanted to do this — and especially this — ever since I met you on the forest trial, back in Villasylvia.” They had done things together that Peron had never imagined — and he used to think that he and Sabrina had tried everything. Lovemaking with Elissa added a whole new dimension. They had stayed together through the night, while the fireworks of Planetfest celebrations fountained and burst above them. And by morning they seemed infinitely close, like two people who had been lovers for many months. But that, thought Peron unhappily, made Elissa’s comment about Sy much harder to take. If she thought Sy was attractive — hadn’t she said very attractive? — did that mean she thought Sy was more interesting than he was? He remembered the last evening on Pentecost as fabulous, but maybe she didn’t feel the same way. Except that everything since then suggested that she did feel that way, and why would she lie to him?

  Peron’s suit gave a gentle whistle, bringing him back from his dreaming. He felt irritated with his own train of thought. No denying it, he was feeling jealous. It was exactly the kind of mindless romantic mushiness that he despised, the sort of thing for which he had so teased Miria, his younger sister. He looked straight ahead. No time for dreaming now. Here came Whirlygig, to teach him a lesson in straight thinking. He was within a couple of kilometers of the surface, travelling almost parallel to it but closing too fast for comfort. Seen through a telescope, Whirlygig was not an interesting object. It was a polished silver ball about two thousand kilometers across, slightly oblate and roughened at the equator. Its high density gave a surface gravity at the poles of a fifth of a gee, a bit more than Earth’s Moon. A person in a spacesuit, freefalling straight down to the surface of Whirlygig, would hit at a speed of two kilometers a second — fast enough that the object in the suit afterwards would hardly be recognizable as human.

  But that was true for a fall toward any planet in the system, and people did not attempt landings on objects of planetary size without a ship; and the composition of Whirlygig was of no particular interest. The planet had been ignored for a long time, until finally some astronomer took the trouble to examine its rotation rate.

  Then interest grew rapidly. Whirlygig was unique. What made it so had happened recently, as geological time is measured. A mere hundred thousand years ago a close planetary encounter had transferred to the body an anomalously high angular momentum. After that event Whirlygig was left spinning madly on its axis, completing a full rotation in only seventy-three minutes. And at that speed, centripetal acceleration on the equator just matched gravitational force. A ship flying in a trajectory that grazed Whirlygig’s surface, moving at 1,400 meters per second at closest approach, could soft-land on the planetoid with no impact at all; and a human in a suit, with only the slightest assistance of suit steering jets, could do the same.

  But theory and practice, thought Peron, were a long way apart. It was one thing to sit and discuss the problem on the Inter-System ship with the other contestants, and quite another to be racing in toward Whirlygig on a tangential trajectory.

  They had drawn lots to see who would be first contestant down. Peron had “won” — Gilby’s term, delivered with a sadistic smile. The others, following in pairs, would face a far easier task because of Peron’s actions of the next few minutes. If he arrived in one piece.

  He wondered what they would do if he didn’t land safely — would they nominate someone else to try again? Or would they abandon the whole idea, and move on to another planet? A contestant in theory had just one shot at the trials (Kallen was a rare exception). But death was an earnest contender in every Planetfest games. The deaths of contestants were never mentioned by the Government, and never given one word of publicity in the controlled news media; but everyone who entered the trials knew the truth. Not everyone went home a winner, or even a loser. Some contestants went forever into the shimmering heat of Talimantor Desert, or to a blood-lapped nightdeath in the woods of Villasylvia, or to a frozen tomb in the eternal snows of Capandor Mountains; or (Peron’s own secret fear) to a slow asphyxiation in the underwater caverns of Charant River. He shivered, and peered ahead. Those dangers were past, but death had not been left behind on Pentecost. He would visit Peron just as readily on Whirlygig. The equipment that Peron was hauling along behind him had seemed small when he left the ship, but now four hundred kilos of lines, springs, and pitons felt like a mountain, trailing half a kilometer directly behind him. Uncontrolled, they would envelop him on landing.

  The surface felt so close that it seemed he could reach out a suited arm and touch it. He made small attitude adjustments with the suit jets. His velocity was just right for a stable orbit about Whirlygig at surface level. He turned his suit to land feetfirst, and touched, gently as a kiss.

  He had landed softly, but at once there was a complication. He found he was at the center of a blinding cloud of dust, pebbles, and rock fragments. Effective gravity here on Whirlygig’s equator was near to zero, and the shower of rock and sand was in no hurry to settle or disperse. Working purely by touch, Peron took one of the two pitons he was carrying, placed it vertically on the surface, and primed the charge. His hands were shaking in the gloves. Must be quick. Only thirty seconds left to secure a firm hold. Then he would have to be ready for the equipment.

  The explosive charge in the top end of the piton exploded, driving the sharp point deep into the planet’s surface. Peron tugged it briefly, made sure it was secure, then for double safety primed and set off the second piton. He braced two loops on his suit around the pitons, and looked back toward the moving bundles of equipment.

  It seemed impossible. The equipment was still a couple of hundred meters away. The whole landing operation — minutes according to his mental clock — must have been completed in just a few seconds. He had time to examine the bundle of equipment closely, and decide just where he would secure it.

  It swung in toward him, drifting down to the surface. The velocity match had been exact. It was less than five minutes work to place another array of pitons in a parabolic curve along the surface, and set up catapult cables to run around the array. The final web of cables and springs looked fragile, but it would hold and secure anything with less than three hundred meters a second of relative velocity.

  Peron made one last examination of his work, then activated the suit phone. “All set.” He hoped his voice was as casual as he would have liked it to be. “Come on in anytime. The catapult is in position.”

  He took a deep breath. Halfway. When they had explored the surface as a group, the catapult would be used to launch all the others away from Whirlygig; and Peron would be alone again. Then he would make a powered ascent (with fingers crossed) to the safety of the waiting ship.

  CHAPTER SIXTEEN

  Peron could not recall the exact moment when he knew that he was going to die on Whirlygig. The knowledge had grown exponentially, over perhaps a minute, as his mind rapidly ran through every possible escape and rejected all of them as impossible. Cold certainty had finally replaced hope.

  The landing had gone almost perfectly, as the six other contestants assigned to visit Whirlygig sailed in to a smooth encounter with the landing web. Wilmer, paired with Kallen, had proved the exception. He had come barrelling in too fast and too high, and only Kallen’s hefty pull on their line had brought him low enough to connect with the cables.

  He seemed not at all upset by his narrow escape. “Guess you were right, Kallen,” he said cheerfully, once he was safely down. “Odd, that. I’d have bet money I had t
he speed accurate and you had it wrong.”

  “Be thankful you weren’t first man in,” said Rosanne severely — she had seen how close Kallen had come to losing his own hold. “If Peron had done that he’d have been in big trouble. And what do you have in there? That’s probably the mass you didn’t allow for in your calculations.”

  Wilmer held up a green case. “In this? Food. I didn’t know how long we’d be here. I’ve no wish to starve, even if you all don’t mind it. And if I had been first one in, Rosanne, with my trajectory I’d also have been first one out. At that speed and height I’d have missed Whirlygig altogether. There’s a moral in that: better come in too high and fast than low and slow.”

  He had begun to hop gingerly from one foot to the other, testing his balance. The effective gravity on Whirlygig’s equator was not exactly zero, but it was so slight that a tumbling upward leap of hundreds of feet was trivially easy. Everyone had tried it, and soon lost interest. It took minutes for the feather-light float down back to the surface, and one experience of that was enough.

  They soon began the careful trek away from Whirlygig’s equator, travelling in small groups and heading for the comforting gravity of the polar regions. Only Sy was left behind, making his own solitary and perplexing experiments in motion over the rough terrain.

  Progress for everyone was slower than expected. They could fly low over the surface with little effort, using the tiny propulsive units flown in after they were all landed. But Whirlygig’s rapid rotation made Coriolis forces a real factor to reckon with, and allowing for them called for constant adjustment to the flight line. The suit computers refused to accept and track a simple north reckoning, and it was easy to stray twenty or thirty degrees off course. After they had been on the way for a couple of hours, Sy caught up and quickly passed them all. He had discovered his own prescription for estimating and compensating for Coriolis effects.

  As they flew north the appearance of the land below gradually changed. The equator was all broken, massive rocks, heaped into improbable, gravity-defying arches, spires, and buttresses. A few hundred kilometers farther toward the pole the terrain began to smooth, settling down into a flatter wilderness of rugged boulders. It was not a pleasant landscape, and the temperature was cold enough to freeze mercury. But compared with some of the other worlds, Whirlygig seemed like vacation-land.

  The suits had efficient recycling systems, and ample food supplies. The contestants agreed to carry on right to the pole, then rest there for a few hours before returning to the equator and leaving. According to Gilby they would find a sizeable research dome at the north pole, where they would be able to sleep in comfort and remove suits for a few hours. All scientific surveys on Whirlygig had been completed many years earlier, but the dome facilities should still be in working order.

  Elissa and Peron had chosen to travel side by side, with their radios set for private conversation. The suit computers would monitor incoming messages and interrupt for anything urgent. Elissa was bubbling over with high spirits and cheerfulness.

  “Lots of things to tell you,” she said. “I didn’t have a chance to talk to you yesterday, you were too busy getting ready for the landing here. But I’ve spent a lot of time making friends with one of the crew members — Tolider, the short-haired one with the pet tardy.”

  “That hadn’t escaped my attention,” said Peron drily. “I saw you petting it and pretending you liked it, too. Disgusting. Why would anybody want a big, fat, hairy pet worm?”

  Elissa laughed. “If I were to tell you what some people want with it, I’d shock your innocent soul. But Tolider just likes it for company, and he looks after it well. Love me, love my tardy, that’s what he seems to think. Once he thought I was a tardy-lover, too, he was ready to bare his soul. Now, are you going to spend the next few hours sounding jealous, or do you want to know what he said?” “Oh, all right.” Peron’s curiosity was too great to allow him to maintain an aloof tone, and he knew from his own experience how good Elissa was at winkling information out of anyone. “What did he tell you?”

  “After he felt comfortable with me we talked about the Immortals. He says they aren’t a hoax, or something invented by the government. And they aren’t human, or alien, either. He says they are machines.”

  “How does he know?”

  “He saw them. He’s been working in space for over twenty years, and he remembers the last time the Immortals came. He said something else, too, once I’d softened him up — shut up, Peron — something that he says the government doesn’t want anyone down on Pentecost ever to know. He told me because he wanted to warn me, because he feels sorry for me. He says that some of the winners of the Planetfest games who go off-planet are sacrifices to the Immortals. They — that means us — will become machines, themselves.”

  “Rubbish!”

  “I agree, it sounds like it. But he made a lot of good points. You hear about the Immortals, but you never hear a description of one — no stories that they’re just like us, or that they’re big or little, or have green hair, or six arms. And you tell me: what does happen to Planetfest winners when they go off-planet?”

  “You know I can’t answer that. But we’ve seen videos of them, after they won the games. How could that happen if they had been converted to machines?” “I’ll tell you what Tolider says — and this is supposed to be common rumor through the whole space division. It’s like an old legend that goes back to the time we were first contacted by the Immortals. We know that the computer records on The Ship were destroyed, but there’s no real doubt that it left Sol over twenty thousand years ago, and travelled around in space until five thousand years ago when it found Pentecost.”

  “No one will argue with that, except maybe your old aunt who thinks we’ve been on Pentecost forever. We were even taught it in school.”

  “But the old records say that everything on Earth was wiped out, and everyone died in the Great Wars. Suppose that’s not true — partly true, but exaggerated. Suppose there were enough people left to start over again, says Tolider, and suppose they survived the bombs and the Long Winter. They wouldn’t be starting from scratch, the way we began on Pentecost. They’d be able to breed back quickly — it took us less than five thousand years to grow from The Ship’s people to over a billion. Earth would have had at least fifteen thousand years to develop their technology, beyond anything we can imagine, while we were wandering round on The Ship, looking for a home. They would have machines hundreds of generations better than our best computers. Maybe they would have reached the point where the dividing line between organic and inorganic would be blurred. We definitely know they have better computers — did you realize that the Immortals, not Pentecost, control space travel through the Cass system, because their computerized tracking system is enormously better than ours? Sy told me that, and he got it from Gilby. Anyway, that’s what Tolider believes: the Immortals are intelligent computers, maybe with biological components, sent here from Earth. There. You’re the smart one — so find a hole in that logic.” They flew along in silence as Peron thought it over.

  “I don’t need to find a logical gap,” he said at last. “Tolider’s story doesn’t fail on logical grounds, it fails on sense. People do things for reasons. If Earth had recovered and gone back to space, they might have sent ships out to look for us, sure — and for the other ships that supposedly left at the same time we did. Suppose that’s true, and suppose they eventually found us. Then they’d come and tell us we had been discovered. Why would they ever not want to tell us? Tolider is repeating old stories. Nothing wrong with that, but you don’t expect legends to make sense. Let me ask you a question that doesn’t depend on myths for an answer. Supposedly we get scientific information from the Immortals, and they drop off a new batch of ideas every twenty years, along with a few rare materials that are in short supply in the Cass system. Right?” “I think that’s definitely true. Tolider says he has actually been involved in the materials transfer. He also says that the
government down on Pentecost is obsessed with control and maintaining the status quo, and that they use new technology to remain in power. That’s why we’ve had a stable, single regime ever since we were contacted by the Immortals, and that’s one reason he prefers to stay out in space where there’s more freedom.”

  “He should meet my father — he’s been saying for years that the government is run by a bunch of repressive tyrants. But don’t you see the problem? The Immortals give us things, and it’s a one-way transfer. Nobody, not even a machine, will stand for a one-way trade for four hundred and fifty years. If all they wanted to do was give us information, they could do that using radio signals. But they actually come here. So here’s my question: What do the Immortals get from their visits to Pentecost?”

  “Some of us, if you want to believe Tolider. You and me, that’s what the government trades to get new information.”

  “That makes even less sense if we want to believe Tolider. We winners are a talented group, but we’re not that special. If Earth had been repopulated to the point where they could explore the stars again, they’d have thousands like us.” “Tolider told me that we are an unusual group. Rumor says it’s the first time for many games that all the top five in the Planetfest games are

  ‘troublemakers’ — he couldn’t define the term for me.”

  “I think I can. We won’t take answers without digging for ourselves. That’s one reason I feel so comfortable with the rest of you.”

  “I’ll accept that. So let me point out one other thing. You can tell me what it means. The contestant groups for surface visits to Glug and Bedlam and Crater and Camel and the other planets were all some random mixture of all twenty-five winners. But look who’s here on Whirlygig: Sy, me, you, Kallen, and Lum — the top five, all ‘troublemakers,’ plus Rosanne and Wilmer. I think Rosanne can be classed as a wild one, too, difficult to control — your hair would curl if I told you some of the things she’s done. And we all wonder about Wilmer. We’ve been specially picked for this trip, and I’m worried about what might happen here.” Peron moved their suits closer together so that he could see her face. He realized she was genuinely worried, not just joking. He reached across to take her suit glove. “Relax, Elissa. You’re as bad as Tolider, all wild surmises. They wouldn’t bring us all this way to dispose of us on Whirlygig. If we are that much nuisance we could have been chucked out of the contest back on Pentecost, and nobody would ever have suspected a thing.” He laughed. “Don’t worry. Now we’ve landed we’re safe enough on Whirlygig.”
