"No, sir. No, because...." Extrone was smiling innocently. "Good. I want you to do something for me." "Yes, sir," Ri said. Suddenly he threw back his head. "Listen!" "Eh?" Extrone said. Extrone shrugged. "I—Look, sir. Listen to me." Ri's lips were bloodless and his hands He crossed to Mia, who, along with him, had been pressed into Extrone's 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 want to use me, sir. Not after I told you.... Please, sir. If anything should happen to me.... Please, sir. Don't do it." "Tie it," Extrone ordered. "No, sir. Please. Oh, it. I could buy half this planet, and he makes me his guide—at less please don't, sir." "Hey, you!" Extrone called. The two of them turned immediately. "Tie it," Extrone said inexorably. Mia looked at his companion. He spat. "What hurts most, he pays us for staked him out, tying the free end of the rope tightly around the base of a scaling tree. "You will scream," Extrone instructed. With his rifle, he pointed Ri was almost slobbering in fear. "Let me hear you scream," Extrone said. Ri moaned weakly. Ri screamed. "See that you keep it up that way," Extrone said. "That's the way I "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 "There's a lot of satisfaction in fooling them, too," Extrone said. "Making them come to your bait, where you can get at them." He opened his right hand. "Choose your ground, set your trap. Bait it." Extrone sat on an upholstered stool before his tent and spat disgustedly and combed his beard with his blunt fingers. Extrone began to tremble with excitement. "Here they come!" The forest sprang apart. Extrone bent forward, the gun still across his 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. Shortly, from the direction of the rocket, a group of four high-ranking "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 beginning to sound like an asthmatic pump. "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 away, in the direction of a resting bearer. "You!" he said. "Hey! Bring "Watch! Watch!" Extrone cried gleefully. And then the aliens sprang their trap. me a drink!" He faced the officers again. He smiled maliciously. "I'm didn't you?" "Yes, sir. When we located it, sir." "You'll destroy this one, too," Extrone said. "We have a tight patrol, sir. It can't slip through. But it might try a 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. I'm quite safe here, I think." The bearer brought Extrone his drink. "Get off," Extrone said quietly to the four officers. Again they turned reluctantly. This time, he did not call them back. Instead, with amusement, he watched until they disappeared into the Extrone nodded. After a moment he said, "You killed one, I believe, on your trip?" Ri shifted. "Yes, sir." Extrone held back the flap of the tent. "Won't you come in?" he asked without any politeness whatever. Ri obeyed the order. "I realize that, sir. That is, I had intended at the first opportunity, 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. 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 talk like this. I don't even want to listen." "When the invasion starts, he'll have to command all uncontaminated. And Extrone stepped out of the tent, fully dressed, surly, letting the flap slap loudly behind him. He stretched hungrily and stared around the camp, his eyes still vacant-mean with sleep. 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. "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?" Lin's face remained impassive. "I guess it seems that way. Sir." Extrone carried the only weapon, slung easily over his shoulder, a powerful blast rifle, capable of piercing medium armor in sustained fire. To his rear, the water carrier was trailed by a man bearing a two-way communication set. Once Extrone unslung his blast rifle and triggered a burst at a tiny, "For you, sir," the communications man said, interrupting his reverie. "Damn," Extrone muttered. His face twisted in anger. "It better be "Extrone. Eh?... Oh, you got their ship. Well, why in hell bother "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 tore off the head-set and handed it to the bearer. "If they call back, find out what they want, first. I don't want to be bothered unless it's important." "Yes, sir." Extrone squinted up at the sun his eyes crinkled under the glare, and Extrone laughed. "This is enough." He gestured with the rifle and stood up. "Wait," Extrone said, combing his beard. "Wait a minute." "Yes?" "Look," Extrone said. "If that's the case, why do we bother tracking "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. " Extrone was seated, petting his rifle. Extrone nodded genially. "The farn beast hunter, eh?" "Yes, sir." Extrone drummed his fingers on the stock of the blast rifle. "Tell me
