by believe in his choice when every star in this forsaken remain sane in all this blackness much longer. Bitterly he thought of how they would die—not knowing within maybe thousands of light years drifted together, four men in bulbous pressure suits like small Dunbar, the oldest of the four, an old space-buster with a face wrinkled like a dried prune, burned by cosmic rays and the suns of worlds so far away they were scarcely credible, had taken command. concentrates. Each suit a rocket, each human being part of a rocket, Four men, thought Russell, held together by an invisible string of taking the lead because he was older and knew where he was and where he was going. Maybe Johnson, second in line, and Alvar who was third, knew too, but were afraid to admit it. how long the four of them had been plunging toward the red-rimmed sun crazy the four of them had blanked out and nobody could say now how more for claiming he knew when he didn't, for his drooling optimism—because he was taking them on into deeper darkness and would laugh that high piping squawking laugh of his and say that the When the four of them had escaped from that prison colony on a find, if they would just follow old Dunbar. That's what all four of of all. We all look alike out here in these big rocket pressure suits, Russell They might have a chance if Alvar and Johnson weren't so damn lacking in self-confidence as to put all their trust in that crazed old was sure his hunch was right. us. Four suns. You guys see those other three suns all around you, "Well, if you'll notice," Russell said, "the one on the left also now "So now," Johnson said, "there's two suns with red rims around them." "We're about in the middle of those four suns aren't we, Dunbar?" "That's right, boys!" yelled old Dunbar in that sickeningly optimistic voice. Like a hysterical old woman's. "Just about in the sweet dark old middle." "You're still sure it's the sun up ahead ... that's the only one with "That's right! That's right," Dunbar yelled. "That's the only one—and Alvar and Johnson would see that he was cracked. million years or more." "When in hell were you ever here?" Johnson said. "You say you were here before. You never said when, or why or anything!" "It was a long time back boys. Don't remember too well, but it was That was—hell, it musta' been fifty years ago. I been too many places nobody's ever bothered to name or chart, to remember where it is, but I been here. I remember those four suns all spotted to form a perfect all these suns and the worlds that go round 'em. Trust me, boys, and been here, long time back." Russell said tightly. "It'll take us a long time won't it? If it's got knowing all the time the old man was crazy, that he was leading them than old Dunbar will ever be, even if he keeps on getting nuttier all four of them hurtled along. "You never know where you'll find people always spring, always spring, boys, and the music plays all night, every night of a long long year...." Russell suddenly shouted. "Keep quiet, Dunbar. Shut up will you?" Johnson said. "Dunbar—how long'll it take us?" "Six months to a year, I'd say," Dunbar yelled happily. "That is—of our hereditary time." "What?" croaked Alvar. Johnson didn't say anything at all. Russell screamed at Dunbar, then quieted down. He whispered. "Six all be crazier than you are—" "We'll make it, boys. Trust ole' Dunbar. What's a year when we know isn't big enough to kill the will of a human being, boys. I been over a whole lot of it, and I know. In the old days—" "The hell with the old days," screamed Russell. whisper. "You calm down now. You younger fellows—you don't look at things the way we used to. Thing is, we got to go straight. People trapped like this liable to start meandering. Liable to start losing the old will-power." He chuckled. Then he saw how the other two stars also were beginning to develop red right. That sun to the right, and the one behind us ... now they ALL motion. Dunbar laughed. "Sure, they all maybe have a touch of red, but it isn't the same, boys. I can tell the difference. Trust me—" Russell half choked on his words. "You old goat! With those old eyes of yours, you couldn't see your way into a fire!" "Don't get panicky now. Keep your heads. In another year, we'll be there—" self-sealing. Nothing appeared to have changed. The four of them "I did it for the three of us," Russell said. "It was either him or us. don't tell me you guys don't see the red rims around all four suns, all four suns all around us. Don't tell me you guys didn't know he was batty, "How could he see any difference in those four stars?" Russell said, now." He sighed. " Shhhh went on ahead, leading the other three at the front of the right?" Sometime later, Johnson said, "We got to decide now. Let's forget the old man. Let's forget him and all that's gone and let's start now and decide what to do." It's never been." Russell said, "I've had a hunch all along that maybe the old man was "I don't know," Johnson sighed. "I been feeling partial toward that one on the right. What about you, Alvar?" month matter anyway out here—hell there never was any time out here until we came along. We make our own time here, and a month don't matter to me." "How can we tell which of us is right?" Alvar said. "It's like "The one to the right," said Johnson. time ... just wake up enough times to give himself another boost with the old life-gun." "We got to face it," Johnson said finally. "We three don't go on together any more." "That's it," said Alvar. "There's three suns that look like they might the old man might have been right about that. If we stick together, the chance is three to one against us. But if each of us makes for one can come and help the other two...." Alvar said, "We each take the star he likes best. I'll go back the right." once you're going, you never stop ... and I guess there isn't any other body to pull him off his course. And what will time matter to from." "Ready, Russ?" aloneness even before Alvar and Johnson used their life-guns and shot out of sight, Johnson toward the left and Alvar back toward that other And old Dunbar shooting right on ahead. And all three of them Fading, he could hear their voices. "Each to his own star," Johnson pressure suit. "An old man," one of them mused. "A very old man. From one of the lost "Yes," another of them said. "But what amazes me is that this old man picked this planet out of all the others. The only one in this entire sector that would sustain life." "Maybe he was just a very lucky old man. Yes ... a man who attains such an age was usually lucky. Or at least that is what they say about the lost sectors." "Maybe he knew the way here. Maybe he was here before—sometime." they did, it was well over a thousand years ago." Another said. "He has a fine face, this old man. A noble face. Whoever he is ... wherever he came from, he died bravely and he knew the way, He had been listening and he stepped forward and raised his arm. "He was old. It is obvious that he fought bravely, that he had great courage, and that he knew the way. He will be given a burial suitable to his stature, and he will rest here among the brave. the path above which the women will carry him to rest."
