Ravdin shook his head. "We are not sick." "Then criminals, perhaps? Being punished for rebellious plots?" "We are not criminals." The Hunter's fist crashed on the desk. "Then why are you "There is no mystery," Ravdin said softly. "We stayed behind was nearly sundown when Ravdin eased the ship down Ravdin met him eye for eye. "I can't say." Dana's voice was sharp. "We're telling you the truth. We A bell chimed softly in his ear. Ravdin forced his attention Ravdin's face flushed hotly. "Much greater things," he With a sigh, Ravdin eased himself out of the seat, his heart Dana stepped forward suddenly, her cheeks flushed. "We The station was completely empty as Ravdin walked down could weave, of their strange, magic power to steal strong men's minds from them and make them like children before low chord of indescribable beauty, rising and falling in the the breeze. Ravdin's uneasiness disappeared shining bright beauty of the city, Ravdin settled back, trying Ravdin and Dana stood there, trancelike, staring transfixed at the gleaming center of light, forcing their joined minds to driven by ancient fears across the eons of space, seeking only peace, even peace with those who drove them. music slowed, singing softly, and Ravdin could see the old he came forward, clapped Ravdin on the shoulder, and let you know," he said. " They're coming , Nehmon! I saw them, hours ago." Ravdin and Dana. His voice was a raging storm of bitterness Well, you failed, do you hear? I didn't hear it, I didn't listen, I didn't ! I'll hunt you down as my fathers hunted you down, I'll bring my people their vengeance and glory, and your foul music will be dead!" come and go in the twinkling of an eye. But I could see them in the twinkling of an eye." "And it couldn't have been anyone else?" "Seven light years," Ravdin said. "Can you imagine it? we are , and they are coming quickly." His eyes filled with fear. "They couldn't known and dreaded for so many thousands of years that history could not remember. As his captives stood mindless But strangely enough he did not kill them. He left them on a cold stone ledge, blinking dumbly at each other as the they had become less his enemies. A tiny seed of doubt had quiet. Not a breath of air stirred in the city. Ravdin stared out "I know. How well I know." "Yet now the Hunters come again, and again we must run away." Ravdin stared at the old man, his eyes suddenly bright. "Not what I've been thinking." Ravdin sat down, clasping Nehmon. Think about that for a moment. We run, and we run, and we run. From what? We run from the Hunters. They're hunting us Ravdin's eyes were bright. "Yes, we flee, we cringe, we hide under stones, we break up our lives and uproot our families, running like frightened animals in the shadows of night and secrecy." He gulped a breath, and his eyes sought Nehmon's they must turn and fight." "We are not animals." Nehmon's voice cut the air like a whiplash. "Animals fight. We do not. We fought once, like animals, and now we must run from the Hunters who continue to fight Ravdin shook his head. "Do you mean that the Hunters are not men like us?" he said. "That's what you're saying, that they are animals. All right. We kill animals for our food, isn't that true? We kill the tiger-beasts in the Jungle to protect ourselves, why not kill the Hunters to protect ourselves?" Nehmon sighed, and reached out a hand to the young man. "I'm sorry," he said gently. "It seems logical, but it's false logic. The Hunters are men just like you and me. Their lives are different, their culture is different, but they are men. And human life is sacred, to us, above all else. This is the fundamental basis of our very existence. Without it we would be Hunters, too. If we fight, we are dead even if we live. That's why we must run away now, and always. Because we know that we must not kill men." "The concert's over!" Ravdin walked to the window, feeling he searched the faces passing in the street for Dana's face, Ravdin turned away from his bride. "Tell her," he said to Dana looked at them, her gray eyes widening in horror. Ravdin nodded wordlessly. Ravdin nodded. "That's the trouble. They come closer every time. This time they will catch us. Or the next time, or the next. And that will be the end of everything for us, unless we running from." gasp and her eyes widened as his words sank home. "Ravdin," Ravdin stared at her, and felt a chill of excitement. Music Ravdin's hand trembled. "I—I don't know. None of us living Dana's face glowed with excitement, alive with new vitality, new hope. "Ravdin, can't you see? our philosophy and culture have matured! Oh, Ravdin, you themselves became a part of it. Even we can see these changes, why couldn't the Hunters have grown and changed just as we have?" grimly. "You're deluding yourself, Dana. They laugh at our music, they scoff at our arts and twist them into obscene mockeries. They have no concept of beauty in their language. The Hunters are incapable of change." "And you can be certain of that when nobody has seen back, Dana." "But she's right all the same," Ravdin said softly. "You're it, Dana and I." Dana looked at her husband, and her eyes were proud. glowing city, sensing somehow that the mystifying circle of so that no eyes, not even the sharpest, would ever know how long they had stayed, nor where they might have gone. In the rounded room of his house, Lord Nehmon dispatched fear. They had Nehmon turned to Ravdin and Dana, his face lined and tired. Dana shook her head. "We'll tell them nothing, unless it's safe for them to know." Ravdin felt the desolation in the people's minds, saw the so dangerous. He knew of the terrible fight, the war of his people against the Hunters, so many thousand years before. They had risen together, a common people, their home a single planet. And then, the gradual splitting of the nations, his own people living in peace, seeking the growth and beauty of the arts, despising the bitterness and barrenness of hatred and killing—and the Hunters, under an iron heel of militarism, of government for the perpetuation of government, split farther and farther from them. It was an ever-widening split as the Hunters sneered and ridiculed, and then grew to hate Ravdin's happiness. Ravdin knew of his people's slowly dawning awareness "We will be safe, outside the city." Dana gripped her husband's frightened animals, and shivering in the cool night air as the bright sparks of the ships' exhausts faded into the black starry sky. A man and a woman alone, speechless, watching, staring tall thicket near the place where the city had stood. Ravdin's dull eyes, weapons strapped to their trim uniforms. The Hunters had blinked at them, unbelieving, with their weapons held at ready. Ravdin and Dana were seized and led to the flagship. As they approached it, their hearts sank and they clasped as he searched their faces dispassionately. The captives were pale and seemed to cringe from the pale interrogation light. "Chickens!" the Hunter snorted. "We have been hunting down chickens." His eyes turned to one of the guards. "They have been searched?" "Of course, master." Ravdin glanced briefly at Dana's white face. His voice
