Moran cut apart the yard-long monstrosity with a slash of flame. together again, too. Also, neither Moran nor any of the others wanted to 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 thrashed out very painstakingly, in formal conference on the space-yacht Nadine Earth, and unless all parts of the complex were present, the total was necessary to get rid of Moran. In their predicament he might have come subtly or glaringly wrong. So mankind distastefully ferried pests as The Nadine was out of overdrive and all the uncountable suns of the Moran observed these things from the control-room of the Nadine , 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!" passage leading away. He called. But Moran observed with grudging landing-point, and they had still to re-locate themselves. They'd been on Coryus Three and they'd gotten departure clearance from its space-port. With clearance-papers in order, they could land unquestioned at any other space-port and take off again—provided the other space-port was one they had clearance for. Without rigid control of space-travel, any criminal anywhere could escape the consequences of covering five persons aboard—four men and a girl Carol. Moran made six. 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 land anywhere for supplies. With five on board, as her papers declared, space-port officials' suspicion of the rest. So he had to be dumped. He couldn't blame them. He'd made another difficulty, too. Blaster in take off from Coryus III with a trip-tape picked at random for guidance. But the trip-tape had been computed for another starting-point, and when the yacht came out of overdrive it was because the drive had been dismantled in the engine-room. So the ship's location was in doubt. It could have travelled at almost any speed in practically any direction for a length of time that was at least Nadine needed to make a planet-fall for this. The rest of the ship's company came into the control-room. Burleigh waved his hand at the speaker. "Listen!" Moran stirred, and he knew that every one of the others was conscious of when Moran had used desperate measures against them. had cleared for Loris. That was where it should make its next landing. The little yacht went on. All five of its proper company watched as the planet's surface enlarged. The ice-cap went out of sight around the bulge of the globe, but no markings government would think defeat. Moran's own situation was perfectly 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 off-planet, and fast. But space-travel regulations are especially designed to prevent such escapes. He'd made a pretty good try, at that. One of the controls on space-traffic required a ship on landing to deposit its fuel-block in the space-port's vaults. The fuel-block was not returned until clearance for departure had been granted. But Moran had waylaid the messenger carrying the fuel-block back to that space-yacht. He'd fuel. He was admitted. He put the block in the engine's gate. He duly took the plastic receipt-token the engine only then released, and he drew a blaster. He'd locked two of the Nadine's 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 hand. He punched the take-off button and only seconds later the 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 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. Now the space-yacht moved toward a vast mass of fleecy whiteness without The Nadine checked her downward motion. Interplanetary drive is rugged and sure, but it does not respond to fine adjustment. Burleigh used rockets, issuing great bellowings of flame, to make actual contact. The There was silence in the control-room save for the whining noise which now was almost deafening. Harper snapped off the switch. Then there was true silence. The space-yacht had come to rest possibly a hundred yards from the mound which was the source of the space-signal. That mound "It's a ship," said Moran curtly. "It crash-landed and its crew set up a off. Maybe they got the lifeboats to work and got away. Maybe they lived to get in the ship." 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!" beacon. I wouldn't count on a boat, Moran." seen no moving thing outside, but arms were simple sanity on an unknown 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 door opened. It was not necessary to check the air specifically. The suits would take care of that. Anyhow the ice-cap said there were no water-soluble gases in the atmosphere, and a gas can't be an active poison if it can't dissolve. They filed out of the airlock. They stood on ash-covered stone, only slightly eroded by the processes which made life possible on this planet. They looked dubiously at the scorched, indefinite substance landed. Moran moved scornfully wing-covers and flew away, droning loudly. The four men heard the sound above even the monstrous cacophony of cries and boomings and grunts and squeaks which seemed to fill the air. Moran grunted. Distastefully, he saw his predicament made worse. He knew operation was necessary before humanity could move in. A complete ecological complex had to be built up microbes to break down the rock "Suppose we go look at the ship?" said Moran unpleasantly. "Maybe you "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 They reached the mound which was the ship. Moran unlimbered his torch. destroy it. Thick fumes arose, and quiverings and shakings began. Black creatures in their labyrinths of tunnels began to panic. Off to the right the blanket-like surface ripped and they poured out. They scuttled crazily here and there. Some took to wing. By instinct the other men—the armed ones—moved back from the smoke. They wore space-helmets but they felt that there should be an intolerable smell. 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
