PLANET of DREAD By MURRAY LEINSTER Illustrator ADKINS Moran cut apart the yard-long monstrosity with a slash of flame. The thing presumably died, but it continued to writhe senselessly. He turned to see other horrors crawling toward him. Then he knew he was being marooned on a planet of endless terrors. Moran, naturally, did not mean to help in the carrying out of the plans go back to the still un-entered wreck while the skinny, somehow which would mean his destruction one way or another. The plans were , with Moran present and allowed to take part in the discussion. necessary to get rid of Moran. In their predicament he might have come prominences erupting about its edges. Now it lay astern, and Moran could see the planet that had been chosen for his marooning. It was a Moran observed these things from the control-room of the , then approaching the world on planetary drive. He was to be left here, with no reason ever to expect rescue. Two of the four-man crew "It doesn't look too bad, Moran!" Moran disagreed, but he did not answer. He cocked an ear instead. He passage leading away. He called. But Moran observed with grudging unquestioned at any other space-port and take off again—provided the other space-port was one they had clearance for. Without rigid control 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 Moran did not know. They might be sent back where they came from. In 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. because the drive had been dismantled in the engine-room. So the ship's The rest of the ship's company came into the control-room. Burleigh "That's a marker," Carol announced. "I saw a costume-story tape once that had that sound in it. It marked a first-landing spot on some planet Moran stirred, and he knew that every one of the others was conscious of expected, and start it up again.

All five of its "I think," said Carol, to Moran, "that if it's too tropical where this 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 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 anybody, and somebody formerly in very great danger would now be safe, 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 the space-port's vaults. The fuel-block was not returned until clearance for departure had been granted. But Moran had waylaid the messenger took the plastic receipt-token the engine only then released, and he crew in the engine-room, rushed to the control-room without encountering the others, dogged the door shut, and threaded in the first trip-tape to come to overdrive. Then the yacht—and Moran—was away. But his present companions got the drive dismantled two days later and once the yacht was out of overdrive they efficiently gave him his choice of surrendering or else. He surrendered, stipulating that he wouldn't be landed back on Coryus he still clung to hope of avoiding return—which was almost certain anyhow. Because nobody would want to go back to a planet from which they'd carried away a criminal, even though they'd done it unwillingly. Investigation of such a matter might last for months. checked her downward motion. Interplanetary drive is rugged fore part was crushed in. The other landing-fins could be traced. "It's a ship," said Moran curtly. "It crash-landed and its crew set up a signal to call for help. None came, or they'd have turned the beacon off. Maybe they got the lifeboats to work and got away. Maybe they lived as I'm expected to live until they died as I'm expected to die." Burleigh said angrily "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 "Aye, aye, sir," said Moran with irony. "Very kind of you, sir. You'll "Then since I can't be trusted with a weapon," said Moran, "I suggest to get in the ship." "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 easily as in ship-clothing. The others of the landing-party donned their "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 torch. They filed into the airlock. The inner door closed. The outer They filed out of the airlock. They stood on ash-covered stone, only landed. Moran moved scornfully wing-covers and flew away, droning loudly. The four men heard the sound Moran kicked again. More holes. More openings. More small tunnels in the " Moran grunted. Distastefully, he saw his predicament made worse. He knew "Suppose we go look at the ship?" said Moran unpleasantly. "Maybe you "We'd better spread out," added Moran, "or else we'll break through that "I'm giving the orders, Moran!" said Burleigh shortly. "But what you say He and the others joined Moran on the yielding surface. Their footing Moran heard muffled noises in his helmet-phone as the others tried to Moran said with savage precision They reached the mound which was the ship. Moran unlimbered his torch. the metal hull that had fallen here before his grandfather was born. Sometimes the flame cut across things that writhed, and he was sickened. But above all he raged because he was to be marooned here. He could not altogether blame the others. They couldn't land at any colonized world with him on board without his being detected as an extra member of the crew. His fate would then be sealed. But they also would be such-and-such fingerprints, voyaging in a space-yacht of such-and-such size and registration. The world they came from would claim them as fugitives. They would be returned to it. They'd be executed. Nadine . They need not maroon him. In fact, they wouldn't dare.
