"No, sir. No, because...." Extrone was smiling innocently. "Good. I want you to do something for me." "What are you going to do?" Ri asked, terrified. Extrone raised his eyebrows. This time, the coughing roar was more distant, but distinct. "It is!" Ri said. "It's a farn beast, all right!" Extrone smiled, almost pointed teeth showing through the beard. "I'm Ri gulped for air. "But ... if there should be more than one?" Extrone shrugged. "I—Look, sir. Listen to me." Ri's lips were bloodless and his hands 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. of a scaling tree. "You will scream," Extrone instructed. With his rifle, he pointed Ri was almost slobbering in fear. our fault Extrone found out." didn't tell Extrone, if that's what you're thinking," Mia said. "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. blasts. 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 forest sprang apart. Extrone bent forward, the gun still across his lap. The farn beast, its tiny eyes red with hate, stepped out on the bank, knees almost stiff. "What in hell do you want?" Extrone asked. Extrone's face looked much too innocent. "How did it get there, gentlemen? Why wasn't it destroyed?" "Look!" Extrone cried excitedly. "Here it comes!" Ri began to scream again. "So?" Extrone mocked. 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 stood up lazily, stretching. He tossed the empty glass away, listened for it to shatter. He reached out, parted the heavy flap to his tent. Extrone nodded. After a moment he said, "You killed one, I believe, on your trip?" Ri glanced nervously around the tent, his sharp eyes avoiding Extrone's "Oh?" Extrone questioned mildly. "I wouldn't say that. I understand that the aliens hunt them quite extensively ... on some of their planets." "Of course you did," Extrone said, lazily tracing the crease of his sleeve with his forefinger. "I imagine these are the only farn beasts 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 "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, Extrone bent forward. " Know me and love me." "Get out!" Extrone said. "It's frightening," Ri said, "to be that close to him." "No?" Mia challenged. "Couldn't we? Not today, but what about tomorrow? 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 the camp, his eyes still vacant-mean with sleep. 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. "They have very long, sharp fangs, and, when enraged, are capable of tearing a man—" "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?" Four hours later, they were well into the scrub forest. Extrone walked 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 fire. To his rear, the water carrier was trailed by a man bearing a folding stool, and behind him, a man carrying the heavy, high-powered two-way communication set. Once Extrone unslung his blast rifle and triggered a burst at a tiny, arboreal mammal, which, upon the impact, shattered asunder, to Extrone's satisfied chuckle, in a burst of blood and fur. "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, "Yes, sir." 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." "Two?" Extrone grinned, petting the rifle. "You and I better go forward and look at the spoor." 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. " "Extrone wants to see you," Lin 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 what they look like," he said suddenly. "Well, sir, they're ... uh...."
