blood," old Dunbar told the space-wrecked, desperate men. But Dunbar's eyes were old and uncertain. How could they how they would die—not knowing within maybe thousands of light years where they were, or where they were going. After the wreck, the four of them had floated a while, floated and drifted together, four men in bulbous pressure suits like small individual rockets, held together by an awful pressing need for each Dunbar, the oldest of the four, an old space-buster with a face Suddenly, Old Dunbar had known where they were. Suddenly, Dunbar knew where they were going. They could talk to one another through the etheric transmitters inside Four men, thought Russell, held together by an invisible string of Dunbar was as crazy as a Jovian juke-bird. How long ago that had been, Russell didn't know. All Russell knew was recognizable pattern. But Dunbar knew. And Russell was looking at Dunbar's suit up ahead, watching it more and more intently, thinking about how Dunbar looked inside that suit—and hating Dunbar more and more for claiming he knew when he didn't, for his drooling optimism—because he was taking them on into deeper darkness and calling their destination Paradise. Russell wanted to laugh, but the last time he'd given way to this repeat. Sometimes Russell thought of other things besides his growing hatred thought then of what Dunbar would say to such a thought, how Dunbar Dunbar had a big answer for every little thing. for Dunbar. Hell no—Dunbar had to start talking about a place they find, if they would just follow old Dunbar. That's what all four of We all look alike out here in these big rocket pressure suits, Russell now, Russell thought—if it weren't for old crazy Dunbar. the wrong direction. No reason for knowing. Just a hunch. And Russell don't you?" "Sure," someone said. "We're about in the middle of those four suns aren't we, Dunbar?" Russell said. "That's right, boys!" yelled old Dunbar in that sickeningly optimistic old middle." "You're still sure it's the sun up ahead ... that's the only one with life on it, Dunbar ... the only one we can live on?" Russell asked. "That's right! That's right," Dunbar yelled. "That's the only one—and Dunbar?" Russell asked. Keep the old duck talking like this and maybe "Yeah," said Alvar. "You still say that, Dunbar?" worlds but ashes ... just ashes and iron and dried blood, dried a million years or more." Russell said tightly. "It'll take us a long time won't it? If it's got spend hoping and getting there—there won't be nothing but ashes and cracked clay?" Russell said. said that one had a red rim, Dunbar, and I wanted to believe it. So Old Dunbar laughed. The sound brought blood hotly to Russell's face. knowing all the time the old man was crazy, that he was leading them wrong. I'd break away, go it alone to the right sun, Russell thought—but I'd never make it alone. A little while out here alone and I'd be nuttier than old Dunbar will ever be, even if he keeps on getting nuttier all was to get rid of Dunbar. Russell said. "Lost people ... lost ... who knows how long," Dunbar said, as the four of them hurtled along. "You never know where you'll find people on a world somewhere nobody's ever named or knows about. Places where 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 Russell screamed at Dunbar, then quieted down. He whispered. "Six crazy as hell, Dunbar. Crazy ... crazy! Nobody could stand it. We'll "We'll make it, boys. Trust ole' Dunbar. What's a year when we know "Now quiet down, Russ," Dunbar said in a kind of dreadful crooning 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." someone says to go right, and someone else says to go in another direction. And then someone says maybe they'd better go back the old way. An' pretty soon something breaks, or the food runs out, and "Shut up!" Johnson yelled. Dunbar laughed. "Boys, boys, don't get panicky. Keep your heads. Just stick to old Dunbar and he'll see you through. I'm always lucky. Only Dunbar. If he'd aimed right, Russell knew the fire-bullet should have pierced Dunbar's back. Now the fire was gone, extinguished Dunbar's last faint cry from inside his suit still rang in Russell's Johnson both called Dunbar's name a few times. There was no answer. "I did it for the three of us," Russell said. "It was either him or us. " Shhhh 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." him because we didn't have the strength to make up our own minds. Why does a crazy man's laugh sound so good when you're desperate and don't know what to do?" "I always had a feeling we were going wrong," Johnson said. "Anyway, Russell said, "I've had a hunch all along that maybe the old man was You're both wrong." He could see himself going it alone. Going crazy because he was alone. He'd have broken away, gone his own direction, long ago but for that fear. "How can we tell which of us is right?" Alvar said. "It's like "The one to the right," said Johnson. "We been going away from the right one all the time," said Alvar. "We got to stay together," said Russell. "Nobody could spend a year out here ... alone...." "Ah ... in another month or so we'd be lousy company anyway," Alvar said. "Maybe a guy could get to the point where he'd sleep most of the together any more." "That's it," said Alvar. "There's three suns that look like they might be right seeing as how we all agree the old man was wrong. But we believe there is one we can live by, because we all seem to agree that 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...." "No ... God no...." Russell whispered over and over. "None of us can Johnson started to laugh. Russell was yelling wildly at them, and above his own yelling he could hear Johnson's rising laughter. "Every old Dunbar? Even less than to us, I guess. He's dead and he won't he would share with no one. Not even crazy old Dunbar. Russell felt the release, felt the sudden inexplicable isolation and 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 red-rimmed sun behind them. And old Dunbar shooting right on ahead. And all three of them "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 "Maybe he knew the way here. Maybe he was here before—sometime." The other shook his head. "I don't think so. They say some humans from to his stature, and he will rest here among the brave. "Let the women dance and the music play for this old man. Let the
