QUEST OF THIG cruiser where his two fellows and himself would drain the creature's mentality of all its knowledge. In this way they could learn whether a shiny-buttoned bane of the typist, but there were no results. Feebly be-chapped outlaws raiding his little trailer home kept rolling up out of his subconscious. Yet he had "There it is," announced Thig, dropping the limp body of the captured "He resembles Thig," announced Kam. "But for the strange covering he wears he might be Thig." "Thig will be this creature!" announced Torp. "With a psychic relay we will transfer the Earthman's memories and meager store of knowledge to the brain of Thig! He can then go out and scout this world without these clumsy sheathing upon his body. On Ortha we do not hamper the use of our limbs so." "Do not question the word of your commander," growled Torp, swelling out his thick chest menacingly. "It is for the good of our people that you disguise yourself as an Earthman." "For the good of the Horde," Thig intoned almost piously as he lifted Terry's body and headed for the laboratory. Service for the Horde was all that the men of Ortha knew. Carefully For ten hours or more the droning hum of the relay sucked Terry's brain proved too violent and his heart faltered after a time and stopped completely. Twice, with subtle drugs they restored pseudo-life to his body and kept the electrical impulses throbbing from his tortured brain, but after the third suspension of life Thig removed his helmet. An hour later, his scars and altered cartilage already healed and painless, Thig again scraped sand over the entrance to the space ship that episode gave Thig an idea about the little lump of jewels in his he acquired the knowledge of Terry that he found himself unconsciously Thig sank into a dusty old swing that hung on creaking chains from the landed. And there Thig balked. Why must they destroy these people, Thig tried to tell himself that it was the transmitted thoughts of the for reasons that he had never known existed. He had learned the heady experienced the primitive joy of matching his wits and tongue against Thig groaned. He was a weakling to let sentimentality so get the better "You have done well," announced Torp when Thig had completed his report "I will recommend the conquest of this planet, 72-P-3 at once and the complete destruction of all biped life upon it. The mental aberrations "But why," asked Thig slowly, "could we not disarm all the natives and "Only the good of the Horde matters!" shouted Torp angrily. "Shall a race of feeble-witted beasts, such as these Earthmen, stand in the way "Let us get back to Ortha at once, then," gritted out Thig savagely. There are forces at work upon Earth that we of Ortha have long forgotten." "Check the blood of Thig for disease, Kam," ordered Torp shortly. "His words are highly irrational. Some form of fever perhaps native to this world. While you examine him I will blast off for Ortha." the invisible radiations from that weapon's hot throat and flesh or it tore free from the feeble clutch of the sand about it, and they were rocketing skyward. Thig's this planet." Kam eyed him coldly and lifted a shining hypodermic syringe from its case. He approached Thig warily, aware that disease often made a maniac Then it was that Thig went berserk. His fists slashed into the thick Kam's startled throat and choked off any cry for assistance before it and dragged his blaster from it. Thig's other hand clamped over his and fought against that lone arm of Thig. weapon tilted upward until it reached the level of Thig's waist. Thig about full upon its owner's thick torso. Thig's fingers pressed down Before Thig's eyes half of his comrade's body sloughed away into foul matter. Horror for what he had done—that he had slain one of his own stupidly for the blow to fall, the end for Ellen and the kids and all Then a thunderclap exploded against his head and he dropped endlessly toward the deck. Blows rained against his skull. He wondered if Torp would ever cease to hammer at him and turn the deadly ray of the weapon upon him. Blood throbbed and pounded with every blow.... hammer they shook his booming head. No longer was Torp above him. He was in the corner of the laboratory, a crumpled blood-smeared heap of bruised flesh and bone. He was unfettered and the blood was caked upon his skull and in his matted hair. Torp must have thought he had killed him with those savage blows upon the head. Even Torp, thought Thig ruefully, gave way to the primitive rage of his ancestors at times but to that very bit of unconscious atavism he now used the blaster to destroy any possibility of remaining life in his unconscious body. Thig rolled slowly over so that his eye found the door into the control room. Torp would be coming back again to dispose of their bodies through the refuse lock. Already the body of Kam was gone. He wondered why he had been left until last. Perhaps Torp wished to take cultures of his blood and tissues to determine whether a disease was responsible for his sudden madness. toward the door. Halfway across the floor he collapsed on his face, the metal of the gun making a harsh clang. He heard the feet of Torp full into the glaring vacant orbs of his commander. Torp leaned there watching him, his breath gurgling brokenly through his deep-bitten lips. The clawing marks of nails, fingernails, furrowed his face and The deadly attack of Thig his own violent avenging of Kam's death, and now the apparent return of the man he had killed come to life had all served to jolt his rigidly trained brain from its accustomed groove. The shock had been too much for the established thought-processes of So Thig shot him where he stood, mercifully, before that vacant mad stare set him, too, to gibbering and shrieking. Then he stepped over the skeleton-thing that had been Torp, using the new strength that victory had given him to drive him along. He had saved a world's civilization from extinction! The thought sobered him all, it had been the Earthwoman and the children he had been thinking of while he battled Kam, a selfish desire to protect them all. He went to the desk where Torp had been writing in the ship's log and read the last few nervously scrawled lines: Planet 72-P-3 unfit for colonization. Some pernicious disease that strikes at the brain centers and causes violent insanity is existent there. Thig, just returned from a survey of the planet, went mad and destroyed Kam. In turn I was forced to slay him. But it is not ended. Already I feel the insidious virus of.... planet Ortha. Unless a rogue asteroid or a comet crossed the ship's path she would return safely to Ortha with that mute warning of danger on 72-P-3. The body of Torp would help to confirm his final message. hull, and cut free from the mother vessel. despite his acquired memory and traits, he was an alien from outer space. He fingered the tiny scars that had completely obliterated the slight heaved a gasp of relief. He was no longer Thig, a creature of a Horde's now, for the rest of his life, he must make up to the dead man's family. The knowledge that Ellen's love was not really meant for him would be a knife twisting in his heart but for her sake he must endure it. Her
