intelligence and missionary-taught ability to speak Earth's language, and had decided to bring Gavir to Earth. The moderator turned to Gavir. "Are you anxious to get back to Mars?" No! Gavir thought. Back behind the Preserve Barrier that killed you instantly if you stepped too close to it? Back to the constant fear of being seized by MDC guards for a labor pool, to wind up in the MDC mines? Mars was where Gavir's father had been pinned, bayonets through his hands and feet, to the wall of a shack just the other side of the Barrier, to die slowly, out of Gavir's reach. Father James told Gavir that the head of MDC himself had ordered the killing, because Gavir's father had tried to organize resistance to the Corporation. Mars was where the magic powers of the Earthmen and the helplessness of the Martian tribes would always protect the head of MDC from Gavir's vengeance. Back to that world of hopeless fear and hatred? I never want to go back to Mars! I want to stay here! But that wasn't what he was supposed to think. Quickly he said, "I will be happy to return to my people." desert beast whose body provided his tribe with all the essentials of existence. At last he saw tracks. He mounted a dune. Out on the plain ran out over the hard, tightly-stretched skin. The drock fell, gave a last convulsion, and lay still. The hunter plunged the blade into the red sand to clean it. He threw back his head and bellowed his hunting cry. There was great glory in killing the drock, for it showed that the Desert Man and not the drock, was lord of the red waste.... Gavir sat down on the divan, exhausted, his song finished. He didn't He began shouting even before Gavir removed his headset. "What kind of a fool are you? Before you started that song, you dreamed things about the Martian Development Corporation that were libelous! I got apartment. We both need sleep. And don't forget, you've been warned not to go prowling around the city by yourself...." As soon as Gavir was sure that Malcomb was out of the hotel and well on his way home, he left his room and went out into the city. In a pitifully few days he would be back in the Preserve, back with the fear of MDC, with hunger and the hopeless desire to find and kill the man who had ordered his father's death. Now he had an opportunity to learn more about the universe of the civilization is explained in books." Gavir wanted to learn. It was his only hope to find an alternative to the short, fear-ridden, impoverished life he foresaw for himself. stopped and stared. Gavir stared back. Earthmen turned to one another. "A Martian." "Let's give pain and death to the Martian! It will be a new experience—one to savor." "Take pain, Martian!" The Earthman with the black hat raised his arm, and the long heavy He began to enjoy it. It was rare that a Martian had an opportunity to knock Earthmen down. The mood of the Song of Going to Hunt at once turned and ran. Gavir drew back his arm and threw the knife retreating enemies. Then he remembered: you couldn't throw far in the gravity of Earth. The Earthmen disappeared into a lift-force field. Gavir decided not to pursue them. He walked forward and picked up his narvoon, and saw that the street on which it lay was solid black pavement, not a force-field. He must be in the lowest level of the city. He didn't know his way around he might meet more enemies. He forgot about the books he'd wanted, and began to search for his hotel. When he got back to his room, he went immediately to bed. He slept late. Malcomb woke him at 1100. Gavir told Malcomb about the strangely-dressed men who had tried to kill him. "I told you not to wander around alone." "But you did not tell me that Earthmen might try to kill me. You have "Why not punish them?" said Gavir. "That Martian boy has power. That song was a fist in the jaw. More!" A woman's voice followed: "If you let that boy go back to Mars I'll never dream a Global program again." More voices: like being mad!" "Keep him on Earth." Hoppy Davery pressed a button in the control panel on his divan, and the voices fell silent. Spurling, president of the Martian Development Corporation." Gavir's hand leaped at the narvoon under his doublet. Earthmen. Here was the man who had ordered his father crucified! Yet he had managed to hide his instant desire to strike, to kill, to carry out the oath of the blood feud then and there. Jarvis Spurling ignored Gavir's hand and stared coldly at him. There was not a trace of the usual Earthman's kindliness in his square, Caution told Gavir to refuse. But before he could speak Spurling lady, we'd deport you so fast your tail would burn. And God help the Bluie!" Sylvie blew a cloud of smoke at Spurling. "You're not on Mars, Jack. You're back in civilization where we do what we damned well please." Spurling laughed. "I've heard about you Century-Plussers. You're all "You can't claim any monopoly on mental health. Not with that concentration camp you run on Mars. Coming, Gavir?" Gavir grinned at Spurling. "The contract, I believe, does not cover my private life." "You screwball Senile Delinquent," Spurling yelled after Sylvie, "you oughtta be locked up!" Lucifer Grotto was in that same quarter in which Gavir had been biggest privately-owned space line, but he likes to call himself the Hat Rat. You must be one of the few people who ever got away from him alive." "He seemed happy to get away from me," said Gavir. An arrangement of force-planes and 3V projections made the front of Lucifer Grotto appear to be a curtain of flames. Gavir hung back, but know what I wanted to do. It was Ethical Conditioning or nothing, so I picked nothing. And here I am, chasing nothing." "How do you chase nothing?" not like a Martian woman, but he found the differences exciting and attractive. He went to her, and he forgot entirely that she was over a allowed this image to turn into a picture of Hoppy Davery withholding bundles of money from a starving Gavir. Then he ended the song. Hoppy sent for him next morning. . He pictured a Desert Man whose father had been killed by a drock. The Desert Man ran over the red sand, and he found the drock. He did not throw his knife. That would not have satisfied his hatred. He fell "Let him come and find me," said Gavir. "Let us go, Sylvie." They went to Lucifer Grotto, where Gavir's wealthiest admirers among the Senile Delinquents were giving a party for him in the Pandemonium Room. The only prominent person missing, as Sylvie remarked after him. Jarvis Spurling's square face was dark with anger. "You deliberately put my face on that animal! You want to make the public hate me. I pay your salary and keep you here on Earth, and this is what I get for it. Mars, Bluie, and you're out hunting a drock. And you find one, only this drock has a gun. How about that, Bluie?" Gavir took out the narvoon, grasped the blade, and drew his arm back. floor and lay there face up, eyes open. The Senile Delinquents of Lucifer Grotto leaned forward to grin at the tattered body.
