<passage>:
This was Burnett's last trip. Three more extended the retriever-claw and culled them into the air-lock. That was all the war-glory he got. Nothing but the stunned, shivering Burnett scowled uneasily and said no. Burnett said, "Lethla?" And then: "Oh, yes! Kriere's majordomo. That right?" "Don't say it calm, Sam. Say it big. Say it big! If Lethla is here in space, then Kriere's not far away from him!" Burnett shrugged. More bodies, more people, more war. What the hell. means Kriere was in an accident, too!" through the void picking up warriors and taking them back to the good green Earth. Grisly, yes, but it's routine. "As for Kriere—if he's anywhere around, he's smart. Every precaution is taken to protect that one." "But Lethla! His body must mean something!" "And if it does? Have we got guns aboard this morgue-ship? Are we a battle-cuiser to go against him?" He stood there, smelling the death-odor in the hot air of the ship, hearing the chug-chug-chug of the blood pumps down below, and his own heart waiting warm and heavy at the base of his throat. "This is my last cargo, Rice. I can't take it any longer. And I don't care much how I go back to earth. This Venusian here—what's his name? Lethla. He's number ninety-eight. Shove me into shelf ninety-nine beside him and get the hell home. That's how I feel!" Lethla was alive. He rose from the floor with slow, easy movements, almost like a dream. He didn't say anything. The heat-blast in his white fingers did all the Burnett swallowed hard. The body had looked funny. Too dead. Now he A crazy thought came ramming down and exploded in Burnett's head. never catch up with the war! But what if the war catches up with you? What in hell would Lethla be wanting aboard a morgue ship? Lethla half-crouched in the midst of the smell of death and the chugging of blood-pumps below. In the silence he reached up with quick "Go find it!" snapped Rice, hotly. "I will." One hand, blue-veined, on the ladder-rungs, Lethla paused. "I know you're weaponless Lethla came down. Like a breath of air on the rungs. He smiled. "That's better. Now. We can talk—" Rice said it, slow: "Interplanetary law declares it straight, Lethla! Get out! Only dead men belong here." Lethla's gun grip tightened. "More talk of that nature, and only dead men there will be." He blinked. "But first—we must rescue Kriere...." "Kriere!" Rice acted as if he had been hit in the jaw. Lethla's voice came next: "Rather unfortunately, yes. He's still alive, heading toward Venus at an orbital velocity of two thousand m.p.h., wearing one of these "Enough!" Lethla moved his gun several inches. "Accelerate toward Venus, mote-detectors wide open. Kriere must be picked up— Rice didn't move. Burnett moved first, feeling alive for the first time in years. "Sure," said Sam, smiling. "We'll pick him up." "No tricks," said Lethla. Burnett scowled and smiled together. "No tricks. You'll have Kriere on board the Constellation in half an hour or I'm no coroner." "Follow me up the ladder." Lethla danced up, turned, waved his gun. "Come on." On the way up, Burnett thought about it. About Lethla poised like a white feather at the top, holding death in his hand. You never knew whose body would come in through the star-port next. Number ninety-eight was Lethla. Number ninety-nine would be Kriere. There were two shelves numbered and empty. They should be filled. And what more proper than that Kriere and Lethla should fill them? But, he chewed his lip, that would need a bit of doing. And even then the cargo wouldn't be full. Still one more body to get He came out of the quick thoughts when he looped his long leg over the hole-rim, stepped up, faced Lethla in a cramped control room that was one glittering swirl of silver levers, audio-plates and visuals. Chronometers, clicking, told of the steady dropping toward the sun at a slow pace. Burnett set his teeth together, bone against bone. Help Kriere escape? See him safely to Venus, and then be freed? Sounded easy, wouldn't be You may never catch up with the war again. The last trip! Yes, this could be it. Capture Kriere and end the war. But what ridiculous fantasy was it made him believe he could actually do it? loved, caressed, tended by his familiar touching. Looking ahead, he squinted. "There's your Ruler now, Lethla. Doing somersaults. Looks dead. A good trick." "Cut power! We don't want to burn him!" Lethla with an intent scowl. Funny. This was the first and the last time anybody would ever board the alive. His stomach went flat, tautened with sudden weakening fear. If Kriere could be captured, that meant the end of the war, the end of shelves stacked with sleeping warriors, the end of this blind searching. Kriere, then, had to be taken aboard. After that— Kriere, the All-Mighty. At whose behest all space had quivered like a smitten gong for part of a century. Kriere, revolving in his neat, water-blue uniform, emblems shining gold, heat-gun tucked in glossy jet holster. With Kriere aboard, chances of overcoming him would be eliminated. Now: Rice and Burnett against Lethla. Lethla favored because of his gun. Kriere would make odds impossible. Something had to be done before Kriere came in. Lethla had to be yanked off guard. Shocked, bewildered, fooled—somehow. But—how? There was a way. And there was a weapon. And the war would be over and this would be the last trip. Sweat covered his palms in a nervous smear. . Kriere smiled. His hands came up. He knew he was about to be rescued. Burnett smiled right back at him. What Kriere didn't know was that he There was only one way of drawing Lethla off guard, and it had to be fast. Lethla watched, intent and cold and quiet. The gun was cold and quiet, too. The claw glided toward Kriere without a sound, now, dream-like in its slowness. It reached Kriere. Burnett inhaled a deep breath. The metal claw cuddled Kriere in its shiny palm. Lethla watched. He watched while Burnett exhaled, touched another lever and said: "You know, Lethla, there's an old saying that only dead men come aboard the Constellation . I believe it." That was the only way to draw Lethla off guard. Burnett spun about and leaped. The horror on Lethla's face didn't go away as he fired his gun. ramrod stabbed Sam Burnett, catching him in the ribs, spinning him back like a drunken idiot to fall in a corner. Fists made blunt flesh noises. Lethla went down, weaponless and Burnett was lying down, not moving, but somehow Rice was going away a
