but the rebellious philosopher: for he destroys worlds. Darkness and the chill glitter of stars. Bo Jonsson crouched on a whirling speck of stone and waited for the man who was coming to kill Stillness answered him. He gulped a heavy lungful of tainted air and rose. The other might be miles away yet, or perhaps very close, catfooting too softly to set up vibrations. A man could do that when The stars blazed with a cruel wintry brilliance, over him, around him, light-years to fall through emptiness before he reached one. He had been alone among them before he had almost thought them friends. Sometimes, on a long watch, a man found himself talking to Vega or them, he did not exist, and they would shine carelessly long after he was gone into night. He had never felt so alone as now, when another man was on the asteroid with him, hunting him down. Bo Jonsson looked at the wrench in his hand. It was long and massive, it would have been heavy on Earth, but it was hardly enough to unscrew the stars and reset the machinery of a universe gone awry. He smiled stiffly at the thought. He wanted to laugh too, but checked himself for fear he wouldn't be able to stop. Let's face it , he told himself. had to be a hunter, too, and track down the other man, before he died. And if he found his enemy, he would probably die anyway. He looked about him. Nothing. No sound, no movement, nothing but the moved here, since the beginning of time when moltenness congealed into death. Not till men came and hunted each other. Slowly he forced himself to move. The thrust of his foot sent him Bo Jonsson's tongue was dry and thick in his mouth. He wanted to genuinely private enterprise: the prospector, the mine owner, the rockhound dreaming of the day when his stake is big enough for him to start out on his own—a race of individualists, rough and noisy and jealous, but living under iron rules of hospitality and rescue. he didn't grate on Bo, they had been partners for several years now. cubicle while Johnny, squinting through a reeking smoke-haze, dialed drinks. Bo was larger and heavier than most spacemen—he'd never have gotten his certificate before the ion drive came in—and was usually content to let others talk while he listened. A placid blond giant, with amiable blue eyes in a battered brown face, he did not consider himself bright, and always wanted to learn. "I don't, Johnny," said Bo. "I'll just nurse a beer." It wasn't morals so much as fastidiousness Bo shook his head and watched his partner move off, swift in the puny her, but Johnny had The Touch. He'd be bringing her back here in a few minutes. Bo sighed, feeling a bit lonesome. If he wasn't going to make a night of it, there was no point in drinking heavily. He had to make the final inspection of the ship tomorrow, and grudged the cost of anti-hangover tablets. Besides what he was putting back into the business, he was trying to build a private hoard some day, he'd retire and get married Johnny made some reply. Bo heaved up his form and strode toward the That was when it happened. Bo saw the little needler spit from the It was the only clear thought which ran in the sudden storm of Bo's head. Bo had seen death before. That needle wasn't anesthetic, it was poison. helpless and soon frozen body would be just another meteor for the next million years. The vague downward sensation of gravity shifted insanely as he moved he had the feeling that the world was tilting around him. near the ground jump up a few feet and it would take you a while to fall back. It was utterly silent around him. He had never thought there could be so much stillness. Bo stood unmoving an instant, fighting the impulse to leap away. He was he wasn't used to this environment, and if he jumped high he could be riddled as he fell slowly down again. Sweat emergency reserve, but a preventive of emergencies, for one man alone might get too tired at the critical moments. Bo knew he wouldn't be allowed to leave Achilles without a certified partner, and unemployed Bo didn't care the first day. He had taken Johnny out to Helmet Hill and laid him in the barren ground to wait, unchanging now, till Judgement Day. He felt empty then, drained of grief and hope alike, She looked impatiently at him out of the screen. "Well," she said, "what's the matter? I thought we were blasting today." "Hadn't you heard?" asked Bo. He found it hard to believe she could "Oh ... I'm sorry. He was such a nice little man—I've been in the lab all the time, packing my things, and didn't know." A frown crossed her labs for nothing. He knew she was still young, and that she had been on Achilles for about a year working on some special project and was now ready to go home. Since coming here, on commission from the Lunar lab, to bring her home, Bo Jonsson had given her an occasional wistful thought. He liked intelligent women, and he was getting tired of rootlessness. But of course it would be a catastrophe if he fell in love with her because she wouldn't look twice at a big dumb slob like him. He had sweated out wassail. Already his friend was cold under the stars. In the course of the evening he found himself weeping. He woke up many hours later. Achilles ran on Earth time but did not rotate on it Bo felt his mouth gape open. "Huh? I never thought—" had one more man aboard than really required, it was cheaper to leave him behind the difference in mass would make up for the fuel loss. I volunteered, even suggested the idea, because ... well, it happened during my watch, and even if nobody blamed me I couldn't help feeling guilty." Bo understood that kind of loyalty. You couldn't travel space without "The Company beamed a message: I'd stay here till their schedule permitted an undermanned ship to come by, but that wouldn't be for modified, no trip ever turned out just as predicted, but that could be done when needed with a slipstick and the little ship's calculator. Bo went at his share of the job doggedly, checking and re-checking before giving the problem to the machine Lundgard breezed through it and spent his time while waiting for Bo in swapping dirty limericks Bo relaxed against the thrust, thinking of Achilles falling away behind Bo clamped his teeth together, as if he would grip consciousness in The plastic patch stuck to his metal gauntlet. He peeled it off, trying not to howl with the fury ripping in his nerves. His body was slow, inert, a thing to fight. There was no more feeling in his back, was he dead already? Bo's mind wavered back toward life. He opened the valves wide on his to lie on naked rock while the enemy hunted him. Bo shuddered and wanted to scream again. Slowly he groped back toward awareness. His frostbitten back tingled as it warmed up again, soon it would be afire. He could feel a hot hours worth left. Lundgard could kill him simply by waiting. It would be easy to die. He lay on his back, staring up at the stars and the spilling cloudy glory of the Milky Way. A warmth was creeping back into numbed hands and feet soon he would be warm all over, and sleepy. His eyelids felt heavy, strange that they should be so heavy on an asteroid. He wanted terribly to sleep.
