<passage>:
he looked down and spat in Jarvis Spurling's dead face. END awaited the moment when his thoughts would be transmitted to millions intelligence and missionary-taught ability to speak Earth's language, and had decided to bring Gavir to Earth. that the head of MDC himself had ordered the killing, because Gavir's father had tried to organize resistance to the Corporation. Mars was Crouching behind crumbling red rocks, racing over flat expanses of orange sand, the hunter sought traces of the seegee, the great slow at him. The hunter saw it out of the corner of his eye at the last moment. His startled sidestep saved him from the neck-breaking snap of the great jaws. arm back, and snapped it forward. The blade struck deep into the throat of the drock. The drock screamed eerily and jumped clumsily. The hunter threw himself at the great, dark body and retrieved the knife. He struck with it again and again into the gray twitching belly. Colorless blood 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.... He began shouting even before Gavir removed his headset. "What kind 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. lash fell on Gavir. He felt a savage sting in the arm he had thrown up to protect his eyes. the face. As the others rushed in, Gavir flailed about him with long him. He sprang free of his attackers and drew his glittering narvoon. The man with the whip yelled. They looked at his knife, and then all at once turned and ran. Gavir drew back his arm and threw the knife with a practiced catapult-snap of shoulder, elbow, and wrist. To his surprise, the blade clattered to the street far short of his retreating enemies. Then he remembered: you couldn't throw far in the "Why?" "What is wrong with them?" last night." Gavir stiffened. They had gotten into trouble because of his next morning. "Best response I've ever seen! The Century-Plussers have been rioting Spurling, president of the Martian Development Corporation." Gavir's hand leaped at the narvoon under his doublet. 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, battered face. "I'm told you got talent. Okay, but a Bluie is a Bluie. products. But one slip like on your first 'cast and you go back to the Preserve." "Mr. Spurling!" said Malcomb. "Your tone is hostile!" "Damn right. That Ethical Conditioning slop doesn't work on me. I've lived too long on the frontier. And I know Bluies." "All finished, Blue Boy? Come on, let's go have a drink at Lucifer Grotto." Caution told Gavir to refuse. But before he could speak Spurling snapped, "Disgusting! An Earth woman and a Bluie! If you were on Mars, lady, we'd deport you so fast your tail would burn. And God help the Bluie!" Spurling laughed. "I've heard about you Century-Plussers. You're all sick." Gavir grinned at Spurling. "The contract, I believe, does not cover my private life." Hoppy Davery said, "Sylvie, I don't think this is wise." Sylvie uttered a short, sharp obscenity, linked arms with Gavir, and strolled out. "You screwball Senile Delinquent," Spurling yelled after Sylvie, "you oughtta be locked up!" attacked. Sylvie told him it was the hangout for wealthier New York Century-Plussers. Gavir told her about the attack, and she laughed. Gavir contemplated her. That she was over a hundred years old was a little frightening. But the skin of her face and her bare upper body was a warm color, and tautly filled. She had lashed out at Spurling, and he liked her for that. But in one way she was like Spurling. She didn't fit into the bland, non-violent world of Malcomb and Hoppy. I wanted to do. And then I found out that I didn't know attractive. He went to her, and he forgot entirely that she was over a hundred years old. In the months that followed, Gavir's fame spread over Earth. By enemies, false friends and callous leaders. It was a protest against sufferings that could neither be borne nor prevented. At the climax of bundles of money from a starving Gavir. Then he ended the song. Hoppy sent for him next morning. "Why did you do that?" he said. "Listen to this." . 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 upon the drock and stabbed and stabbed. The Desert Man howled his hunting-cry over the body of his enemy, and spat into its face. And the fanged face of the drock turned into the square, battered face of Jarvis Spurling. Gavir held the image in his mind for a long moment. When the dreamcast was over, a studio page ran up to Gavir. "Mr. Spurling wants to see you at once, at his office." "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 refilled from nozzles of molded fire. An hour passed from the time of Gavir's arrival. Then Jarvis Spurling joined the party. There was a heavy frontier sonic pistol strapped at his waist. A protesting Malcomb was behind 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. pistol out and pointed it at Gavir. Gavir stood up. His right hand plucked at his doublet. "You're itching to go for that throwing knife," said Spurling. "Go on! Take it out and get ready to throw it. I'll give you that much chance. Let's make a game out of this. We'll make like we're back on arm. "This ancient shotgun I dedicate to your blood feud. I shall hunt down your enemy, Gavir!" Spurling turned. The Hat Rat saw him. "The enemy!" the Hat Rat shouted. The shotgun exploded. Spurling's body was thrown back against Gavir. Gavir saw a huge ragged red caved-in place in Spurling's chest. Spurling's body sagged to the floor and lay there face up, eyes open. The Senile Delinquents of Lucifer Grotto leaned forward to grin at the tattered body. Still holding the narvoon, Gavir stood over his dead enemy. He threw back his head and howled out the hunting cry of the Desert Men. Then
