"No, sir. No, because...." Extrone was smiling innocently. "Good. I want you to do something for me." Extrone raised his eyebrows. This time, the coughing roar was more distant, but distinct. Ri gulped for air. "But ... if there should be more than one?" Extrone shrugged. sir, it wouldn't matter, because he said he ought to kill you. I wouldn't...." Extrone said, "Which one is he?" "That one. Right over there." "The one with his back to me?" "Yes, sir. That's him. That's him, sir." Extrone aimed carefully and fired, full charge, then lowered the rifle "Hey, you!" Extrone called. The two of them turned immediately. Ri was almost slobbering in fear. "Let me hear you scream," Extrone said. Ri moaned weakly. "You'll have to do better than that." Extrone inclined his head toward Ri screamed. "See that you keep it up that way," Extrone said. "That's the way I Extrone dug his boot cleats into the tree, braced himself. "I like this. There's more excitement in waiting like this than in anything I know." Extrone we'd hunted this area." "I didn't think a Club pilot would do that." "After Extrone said he'd hunt farn beasts, even if it meant going to the alien system? Listen, you don't know.... Wait a minute." "How do you know?" "Hear the lower pitch, the more of a roar?" "Hey!" Extrone shouted. "You, down there. There are two coming. Now let's hear you really scream!" Ri, below, whimpered childishly and began to retreat toward the tether tree, his eyes wide. "There's a lot of satisfaction in fooling them, too," Extrone said. "I've always liked to hunt," Extrone said. "More than anything else, I think." "No," Extrone argued. "People should hunt for the love of hunting." "Killing?" "Hunting," Extrone repeated harshly. "He's good bait," Extrone said. "He's fat enough and he knows how to scream good." Extrone sat on an upholstered stool before his tent and spat disgustedly and combed his beard with his blunt fingers. Shortly, from the direction of the rocket, a group of four high-ranking Extrone began to tremble with excitement. "Here they come!" the officers, with military discipline holding their waists in and knees almost stiff. "What in hell do you want?" Extrone asked. They stopped a respectful distance away. "Sir...." one began. The forest sprang apart. Extrone bent forward, the gun still across his lap. "Wait," Extrone said. "Let's see what they do." He had not moved the rifle. He was tense, bent forward, his eyes slitted, his breath Extrone's face looked much too innocent. "How did it get there, gentlemen? Why wasn't it destroyed?" "So?" Extrone mocked. "We thought you ought to return to a safer planet, sir. Until we could locate and destroy it." Extrone stared at them for a space. Then, indifferently, he turned "Watch! Watch!" Extrone cried gleefully. And then the aliens sprang their trap. didn't you?" "Yes, sir. When we located it, sir." "You'll destroy this one, too," Extrone said. Extrone said, "To begin with, they probably don't even know I'm here. And they probably couldn't hit this area if they did know. And you can't afford to let them get a shot at me, anyway." Extrone plucked at his right ear lobe, half closing his eyes. "You'll lose a fleet before you'll dare let anything happen to me, gentlemen. Extrone nodded. After a moment he said, "You killed one, I believe, on your trip?" Extrone held back the flap of the tent. "Won't you come in?" he asked without any politeness whatever. "Oh?" Extrone questioned mildly. "I wouldn't say that. I understand that the aliens hunt them quite extensively ... on some of their planets." Ri waited uneasily, not answering. "Yes," Extrone said, "I imagine they are. It would have been a shame if you had killed the last one. Don't you think so?" Extrone pursed his lips. "It wouldn't have been very considerate of you to—But, still, you gained valuable experience. I'm glad you agreed to Extrone's lip twisted in wry amusement. "If I had waited until it was safe for me to hunt on an alien planet, I would not have been able to find such an illustrious guide." sir...." "Of course," Extrone said dryly. "Like all of my subjects," he waved his hand in a broad gesture, "the highest as well as the lowest slave, know me and love me. I know your intentions were the best." Extrone bent forward. " Know me and love me." Know you and love you, sir," Ri said. "Get out!" Extrone said. "It's frightening," Ri said, "to be that close to him." Extrone cut off our trade with the aliens. Partly to keep them from learning that he was getting ready to invade them, but more to keep them from exposing uncontaminated. And Extrone stepped out of the tent, fully dressed, surly, letting the flap slap loudly behind him. He stretched hungrily and stared around and yet behind him, a fourth, with a steaming pitcher and a drinking mug. Extrone ate hugely, with none of the delicacy sometimes affected in his conversational gestures. When he had finished, he washed his mouth with water and spat on the ground. Extrone pushed the table away. He smacked his lips wetly. "Very ludicrous, Lin. Have you noticed that I have two businessmen for guides? It occurred to me when I got up. They would have spat on me, "An alien?" Extrone corrected. "There's not enough difference between us to matter, sir. Of tearing an alien to pieces, sir." Extrone laughed harshly. "It's 'sir' whenever you contradict me?" tree trunks, sometimes far, sometimes near. Extrone carried the only weapon, slung easily over his shoulder, a powerful blast rifle, capable of piercing medium armor in sustained "Blasted them right out of space," the voice crackled excitedly. "Right in the middle of a radio broadcast, sir." "I don't want to listen to your gabbling when I'm hunting!" Extrone Extrone squinted up at the sun his eyes crinkled under the glare, and perspiration stood in little droplets on the back of his hands. Extrone's eyes lit with passion. Lin's face was red with heat and grimy with sweat. "There were two, I think." Extrone laughed. "This is enough." He gestured with the rifle and stood up. off. They went a good distance through the forest, Extrone becoming more Extrone clenched the blast rifle convulsively. The farn beast coughed again, more distant this time. fast, too." "Eh?" Extrone said. "Wait," Extrone said, combing his beard. "Wait a minute." "Yes?" "They're too unpredictable. It wouldn't be safe. I'd rather have surprise on our side." "You don't seem to see what I mean," Extrone said. " We "Extrone wants to see you," Lin said. Ri twisted at the grass shoot, broke it off, worried and unhappy. "What's he want to see
