to waste a few hours of my time first?" Link "There is no mystery," Ravdin said softly. "We stayed behind to plead for peace." his face tired. "I might have known. Peace! Where have your people gone?" Ravdin met him eye for eye. "I can't say." Dana's voice was sharp. "We're telling you the truth. We want peace, nothing more. This constant hunting and running is senseless, exhausting to both of us. We want to make peace meet him, circle upon circle of silver needles pointing skyward. could weave, of their strange, magic power to steal strong men's minds from them and make them like children before tonight, and even from two miles away, the beauty of four hundred perfectly harmonized voices was carried on the breeze. Ravdin's uneasiness disappeared anticipating his return, would not be at the concert. Riding the shuttle over the edges of Jungle-land toward the shining bright beauty of the city, Ravdin settled back, trying to clear his mind of the shock and horror he had encountered overpowering wave, filling his mind with strange and wonderful images. The stone shimmered and changed, taking the form of dancing clouds of light, swirling with the music as it desperately to reach into the heart of it, to become part of it. Ravdin and Dana stood there, trancelike, staring transfixed at the gleaming center of light, forcing their joined minds to create the crashing, majestic chords as the song lifted from the body frozen in mid-air, and then, abruptly, she was gone, leaving only the barest flickering image of her fiery hair. The music slowed, singing softly, and Ravdin could see the old brilliance. His huge hand caught the hypnotic stone and swept it into crashing, ear-splitting cacophony against the cold steel bulkhead. He stood rigid, his whole body shaking, eyes blazing with fear and anger and hatred as he turned on Ravdin and Dana. His voice was a raging storm of bitterness drowning out the dying strains of the music. "Spies! You thought you could steal my mind away, make me forget my duty and listen to your rotten, poisonous noise! "Take them out! Whip them, burn them, do anything! But find out where their people have gone. Find out! Music! We'll take the music out of them, once and for all." vicious eyes burning in frustration, and their own screams, rising with each question they would not answer until their together the hoarse words that could deliver them. Not words that Frankle could hear, but words to bring deliverance, to blank out their minds like a wet sponge over slate. The hypnotic key clicked into the lock of their minds their screams died in their brains. Frankle stared at them, and knew instantly what they had done, a technique of memory obliteration known and dreaded for so many thousands of years that history could not remember. As his captives stood mindless Three thoughts alone filled their empty minds. Not thoughts of Nehmon and his people forgotten as completely as if he had never been. No thoughts of the Hunters, either, nor of their unheard-of mercy in leaving them their lives—lives of memoryless oblivion, like animals "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. "I've spent many years thinking, my son." "Not what I've been thinking." Ravdin sat down, clasping his hands in excitement. "The Hunters come and we run away, Nehmon. Think about that for a moment. We run, and we run, 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 on the polished pavement as the people passed slowly, their voices carrying a hint of puzzled uneasiness. "The concert's over!" Ravdin walked to the window, feeling a chill pass through him. "So soon, I wonder why?" Eagerly he searched the faces passing in the street for Dana's face, sensing the lurking discord in the quiet talk of the crowd. Suddenly Ravdin turned away from his bride. "Tell her," he said to the old man. Dana looked at them, her gray eyes widening in horror. "The Hunters! They've found us?" Ravdin nodded wordlessly. Her hands trembled as she sat down, and there were tears running from." There was a startled silence. The girl's breath came in a gasp and her eyes widened as his words sank home. "Ravdin," she said softly, " Ravdin stared at her, and felt a chill of excitement. Music burst from the sounding-board, odd, wild music, suddenly hopeful. "No," he said, "no, of course not. You know that." Ravdin's hand trembled. "I—I don't know. None of us living now, no. It's been too long since they last actually found He stared at her. "They keep coming. They keep searching for us. What more proof do you need?" Dana's face glowed with excitement, alive with new vitality, new hope. "Ravdin, can't you see? They might have changed. 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. changed, you wouldn't stand a chance. You'd never come back, Dana." "But she's right all the same," Ravdin said softly. "You're To run away. In the darkness of secrecy, to be gone, without a trace, without symbol or vestige of their presence, leaving only the scorched circle of land for the jungle to reclaim, so that no eyes, not even the sharpest, would ever know how Dana shook her head. "We'll tell them nothing, unless it's safe for them to know." "They'll question you, even torture you." She smiled calmly. "Perhaps they won't. But as a last resort, we can blank out." Nehmon's face went white. "You know there is no coming back, once you do that. You would never regain your memory. You must save it for a last resort." Ravdin felt the desolation in the people's minds, saw the utter hopelessness in the old man's face, and suddenly felt the 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 of the sanctity of life, shattered abruptly by the horrible wars, and then the centuries of fear and flight, hiding from the count-down." "We will be safe, outside the city." Dana gripped her husband's hand, trying to transmit to him some part of her strength and confidence. "Wish us the best, Nehmon. If a link frightened animals, and shivering in the cool night air as the bright sparks of the ships' exhausts faded into the black starry blackening, bubbling into a vanishing memory before their eyes. The flames shot high, carrying with them the last hissing, screeching, landing with a grinding crash in the 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 his eyes on them for a long moment. Finally he said, "Well?" Ravdin glanced briefly at Dana's white face.
