It We'll stage everything on the most colossal raid of the century." Marnagan winced. "You breathing oxygen or whiskey?" of Marnagan capturing Raider's Base. I want a picture of Gunther's face was pretentious enough to be Gunther's quarters. picked up and hurled against a lever-bank, and that Marnagan wasn't pushed him into a room where Gunther sat. Hathaway looked at him. "So you're Gunther?" he said, calmly. The could speak, Hathaway said: "Everything's over with, Mr. Gunther. The Patrol is in the city now and we're capturing your Base. Don't try to fight. We've a thousand men against your eighty-five." Gunther sat there, blinking at Hathaway, not moving. His thin hands nearest thing, and held on. You came hunting for a space-raider and you ended up cradled in a slab-sized Irishman's arms, diving at a hunk of pursued to the death by the Beasts. One of you escaped, it seemed." ?" yelled Marnagan inside his helmet. "Impossible!" "I can't respect your opinion, Mr. Gunther." A shouting rose from the Plaza. About fifty of Gunther's men, lounging "Both. The other guy went after the Patrol." started yelling. Gunther turned slowly to the huge window in one side Across the Plaza, marching quietly and decisively, came the Patrol. he and Marnagan rattled Five hundred Patrolmen in one long, incredible line, carrying paralysis Gunther babbled like a child, his voice a shrill dagger in the air. "Get out there, you men! Throw them back! We're outnumbered!" Guns flared. But the Patrol came on. Gunther's men didn't run, Hathaway had to credit them on that. They took it, standing. guns with them in their tight hands. from filming it. Everything was too wild, hot and angry. Gunther was fragile, bony legs and their atrophied state. Some of the Patrol were killed. Hathaway chuckled again as he saw three of the Patrolmen clutch at their hearts, crumple, lie on the ground and that pierced through his vac-suit, and silence. He wriggled out of the Gunther raged, and swept a small pistol from his linked corselet. He Then Hathaway took a picture of Gunther slumped at his desk, the chaos taking place immediately outside his window. The pirates broke and fled, those that were left. A mere handful. And capture that Gunther lad!" mashed and scattered. They were lucky to have escaped. Or Hathaway went on saying his thoughts: "This is Gunther's work. He's whose dirty face has never been seen, Gunther by name, finally wins limbless, suddenly. "Irish! We lost weight, coming over that ridge!" "Are you telling me? It's man-made. Better than that—it's Gunther! No Gunther'd do anything to—did I say in the air. Fangs caught starlight white on them. Hathaway yelled and ran, Marnagan at his heels, lumbering. Sweat broke cold on his body. The immense things rolled, slithered and squirmed they can't get us in here!" Click's voice gasped it out, "Damn your damn camera!" yelled Marnagan. "They might come in!" "Use your gun." "They got impervious hides. No use. Gahh! And that was a pretty chase, and Gunther and— "Then," retorted Marnagan, "we'll develop it for our own benefit while waitin' for the U.S. Cavalry to come riding over the hill to our rescue!" Hathaway snorted. "U.S. Cavalry." Marnagan raised his proton-gun dramatically. "Snap me this pose," he said. "I paid your salary to trot along, photographing, we hoped, my capture of Gunther, now the least you can do is record peace his mind was whirring faster than his camera as he spun a picture of Marnagan standing there with a useless gun pointed at the animals. wall that holed them in. Click took them all, those shots, not saying up arguing about Gunther. Click came back at him: "Gunther drew us down here, sure as Ceres! That gravity change we felt that proves it. Gunther's short on men. So, It's a good front, this damned iron pebble. From it, Gunther strikes tend to them. It all looks like Nature was responsible. See how subtle his attack is? Looks like accidental death instead of murder, if the Patrol happens to land and finds us. No reason for undue investigation, then." "I don't see no Base around." with nothing Marnagan shooting his gun at tried pushing past him. "Get out of the way," said Hathaway. at me! I'm in one piece. Why, hell, the damned things turned tail and ran away!" "Ran, hell!" cried Hathaway, rushing out, his face flushed and hunk, I couldn't help—Look, now, about Gunther. Those animals are part Gunther's Base, fight our way in, and get fresh oxy-cannisters." Click attached his camera to his mid-belt. "Gunther probably thinks we're "Hold tight, hell, let's move. We've got to find where those animals came from! And the only way to do that is to get the animals to come back!" "Come back? How?" A soundless deluge of them, pouring over the rubbled horizon, swarming in malevolent anticipation about the two men. sending station for these telepathic brutes. Come on!" Hathaway sludged into the pressing tide of color, mouths, contorted faces, silvery fat bodies misting as he plowed through them. besides, Click, I like to look at them. They're pretty." The outpour of animals came from a low lying mound a mile farther on. Evidently the telepathic source lay there. They approached it warily. "We'll be taking our chances on guard," hissed Irish. "I'll go ahead, draw their attention, maybe get captured. Then, you show up with "All right, put 'em up!" a new harsh voice cried over a different radio. One of Gunther's guards. Three shots sizzled out, and Marnagan bellowed. gun up now. Oh, so it's you. I thought Gunther had finished you off. How'd you get past the animals?" "I tied them pink elephants of Gunther's in neat alphabetical bundles and stacked them up to dry, ya louse!" Marnagan said. "But, damn you, they killed my partner before he had a chance!" The guard laughed. let himself down in, quiet and soft. He didn't have a weapon. He didn't you stand right there and die," he said quietly. "That what Gunther twitch and I'll blast you and the whole damned wall out from behind you! Freeze!" Ten minutes later, Marnagan and Hathaway, fresh tanks of oxygen on their backs, Marnagan in a fresh bulger and helmet, trussed the guard, short-handed of men. Gunther simply waited for specific cargo ships to rocket by, pulled them or knocked them down and swarmed over them for cargo. The animals served simply to insure against suspicion and the "What good would that do?" Hathaway gnawed his lip. "They wouldn't fool the engineers who created them, you nut." Marnagan exhaled disgustedly. "Ah, if only the U.S. Cavalry would come riding over the hill—"
