I. Moran cut apart the yard-long monstrosity with a slash of flame. but they killed. Blast-rifles did not. And Harper needed to pull himself together again, too. Also, neither Moran nor any of the others wanted to was being marooned on a planet of endless terrors. Moran, naturally, did not mean to help in the carrying out of the plans which would mean his destruction one way or another. The plans were go back to the still un-entered wreck while the skinny, somehow The thing presumably died, but it continued to writhe senselessly. , with Moran present and allowed to take part in the discussion. From the viewpoint of the He turned to see other horrors crawling toward him. Then he knew he ship's company, it was simply necessary to get rid of Moran. In their predicament he might have come Nadine's to the same conclusion but he was not at all enthusiastic about their Nadine The ice-cap, by its existence and circular shape, proved that the planet man could endure the air and temperature conditions he would find. Moran observed these things from the control-room of the effective against such creatures as these. Torches were contact weapons watched out the same ports as the planet seemed to approach. Burleigh said encouragingly "It doesn't look too bad, Moran!" Moran disagreed, but he did not answer. He cocked an ear instead. He heard something. It was a thin, wabbling, keening whine. No natural radiation sounds like that. Moran nodded toward the all-band speaker. "Do you hear what I do?" he asked sardonically. was something else. Burleigh said: "Hm ... Call the others, Harper." Harper, prudently with him in the control-room, put his head into the passage leading away. He called. But Moran observed with grudging respect that he didn't give him a chance to do anything drastic. These thrashed out very painstakingly, in formal conference on the space-yacht people on the had clearance papers covering five persons aboard—four men and a girl Carol. Moran made six. Wherever the yacht landed, such a disparity between its documents and its crew would spark an investigation. A lengthy, incredibly minute investigation. Moran, at least, would be picked out as a fugitive from Coryus Three. The others were fugitives too, from some unnamed world Moran did not know. They might be sent back where they came from. In could not land anywhere for supplies. With five on board, as her papers declared, she could. And Moran was the extra man whose presence would rouse space-port officials' suspicion of the rest. So he had to be dumped. "It's weak," observed Burleigh. "We'll try answering it." Moran stirred, and he knew that every one of the others was conscious of the movement. But they didn't watch him suspiciously. They were alert by expected, and start it up again. Moran considered the story probable. when Moran had used desperate measures against them. provide food in a minimum of time. It was not an encouraging thought, though, and Moran grimaced. She hadn't said anything about being sorry that he had to be marooned. Maybe she was, but rebels learn to be practical or they don't live long. Moran wondered, momentarily, what sort of world they came from and why they had revolted, and what sort of set-back to the revolt had sent the five off in what they considered a strategic retreat but their government would think defeat. Moran's own situation was perfectly clear. He'd killed a man on Coryus III. His victim would not be mourned by which was the reason for what Moran had done. But the dead man had been very important, and the fact that Moran had forced him to fight and killed him in fair combat made no difference. Moran had needed to get for departure had been granted. But Moran had waylaid the messenger now was almost deafening. Harper snapped off the switch. Then there was alive. And something shrieked in lunatic fashion and something else still moaned from time to time with the volume of a steam-whistle.... "This sounds and looks like a nice place to live," said Moran with fine irony. Burleigh did not answer. He turned down the outside sound. Burleigh scowled. Harper flicked off the direction-finder. Moran said bitingly "That ain't no hillock, that's my home!" "It's a ship," said Moran curtly. "It crash-landed and its crew set up a Burleigh said angrily "You'd do what we are doing if you were in our shoes!" "Sure," said Moran, "but a man can gripe, can't he?" "You won't have to live here," said Burleigh. "We'll take you somewhere up by the ice-cap. As Carol said, we'll give you everything we can something in it of use to you, too. You'd better come along when we explore." "Aye, aye, sir," said Moran with irony. "Very kind of you, sir. You'll go armed, sir?" Burleigh growled "Naturally!" "Then since I can't be trusted with a weapon," said Moran, "I suggest "Right," growled Burleigh again. "Brawn and Carol, you'll keep ship. The rest of us wear suits. We don't know what that stuff is outside." Moran silently went to the space-suit rack and began to get into a "If there's a lifeboat left," said Carol suddenly, "Moran might be able "Ah, yes!" said Moran. "It's very likely that the ship hit hard enough to kill everybody aboard, but not smash the boats!" "Somebody survived the crash," said Burleigh, "because they set up a beacon. I wouldn't count on a boat, Moran." "I don't!" snapped Moran. world. Moran, though, would not be permitted a weapon. He picked up a Nadine landed. Moran moved scornfully Moran kicked again. More holes. More openings. More small tunnels in the " Moran grunted. Distastefully, he saw his predicament made worse. He knew what had happened here. He could begin to guess at other things to be discovered. It had not been practical for men to move onto new planets "We'd better spread out," added Moran, "or else we'll break through that skin and be floundering in this mess." "I'm giving the orders, Moran!" said Burleigh shortly. "But what you say does make sense." He and the others joined Moran on the yielding surface. Their footing was uncertain, as on a trampoline. They staggered. They moved toward the somehow sedate. Moran heard muffled noises in his helmet-phone as the others tried to speak. Carol's voice came anxiously " What's the matter? What do you see? " Moran said with savage precision "We're looking at an inch-worm, grown up like the beetles only more so. Moran slashed and slashed angrily with the big flame, cutting a way to the metal hull that had fallen here before his grandfather was born. Sometimes the flame cut across things that writhed, and he was sickened. He heard blast-rifles firing. He heard Burleigh pant commands. He was on his way out of the hollow he'd carved when he heard Harper cry out horribly. He got clear of the newly burned-away stuff. There was still much smoke and stream. But he saw Harper. More, he saw the thing that had Harper. It occurred to him instantly that if Harper died, there would not be too many people on the Nadine A ship that came in to port with two few on board would be investigated as thoroughly as one that had too many. Perhaps more thoroughly. So if Harper were killed, Moran would be needed to take his place. He'd go on from here in the Nadine
