【正文】 e she would e back to him, and maybe she wouldn39。t. It wouldn39。t change his life either way, but it might change hers. She emerged dripping and infinitely cleaner from the murky water. She dressed again in her random scraps, for whatever good it did her, and came to him, shivering. I39。m cold, she said. Here. He took off his jacket. She looked at his hands as he wrapped it around her, and she reached out and touched the hardness of his shoulder. You sure must be strong, she mented. Pretty strong. I work hard, being a pusher. Just what is a pusher? she said, and stifled a yawn. Come sit on my lap, and I39。ll tell you. He did tell her, and it was a very good story that no adventurous child could resist. He had practiced that story, refined it, told it many times into a re corder until he had the rhythms and cadences just right, until he found just the right words not too difficult words, but words with some fire and juice in them. And once more he grew encouraged. She had been tired when he started, but he gradually caught her attention. It was possible no one had ever told her a story in quite that way. She was used to sitting before the screen and having a story shoved into her eyes and ears. It was something new to be able to interrupt with questions and get answers. Even reading was not like that. It was the oral tradition of storytelling, and it could still mesm erize the nth generation of the electronic age. That sounds great, she said, when she was sure he was .through. You liked it? 1 really truly did. 1 think I want to be a pusher when I grow up. That was a really neat story. Well, that39。s not actually the story I was going to tell you. That39。s just what it39。s like to be a pusher. You mean you have another story? Sure. He looked at his watch. But I39。m afraid it39。s getting late. It39。s almost dark, and everybody39。s gone home. You39。d probably better go too. She was in agony, torn between what she was supposed to do and what she wanted. It really should be no contest, if she was who he thought she was. Well . . . butbut I39。ll e back here tomorrow and you39。 He was shaking his head. My ship leaves in the morning, he said. There39。s no time. Then tell me now! I can stay out. Tell me now. Please please please? He coyly resisted, harrumphed, protested, but in the end allowed himself to be seduced. He felt very good. He had her like a fivepound trout on a twenty pound line. I t wasn39。t sporting. But, then. he wasn39。t playing a game. So at last he got to his specialty. He sometimes wished he could claim the story for his own. but the fact was he could not make up stories. He no longer tried to. Instead, he cribbed from every fairy tale and fantasy story he could find. If he had a genius, it was in adapting some of the elements to fit the world she knewwhile keeping it strange enough to enthrall herand in adlibbing the end to personalize it. It was a wonderful tale he told. It had enchanted castles sitting on mountains of glass, moist caverns beneath the sea, fleets of starships, and shining riders astr ide horses that flew the galaxy. There were evil alien creatures, and others with much good in them. There were drugged potions. Sca led beasts roared out of hyperspace to devour plas. Amid all the turmoil strode the Prince and Princess. They got into frightful jams and helped each other out of them. The story was never quite the same. He watched her eyes. When they wandered, he threw away whole chunks of story. When they widened, he knew what parts to plug in later. He tailored it to her reactions. The child was sleepy. Sooner or later she would surrender. He needed her in a trance state, neither awake nor asleep. That wa s when the story would end . . . . and though the healers labored long and hard, they could not save the Princess. She died that night, far from her Princ e. , Her mouth was a little round o. Stories were not supposed to end that way. Is that all? She died and she never saw the Prince again? Well, not quite all. But the rest of it probably isn39。t true, and I shouldn39。t tell it to you. Ian felt pleasantly tired. His throat was a little raw, making him hoarse. Radiant was a warm weight on his lap. You have to tell me, you know, she said reasonably. He supposed she was right. He took a deep breath. All right. At the funeral, all the greatest people from that part of the galaxy were in attendance. Among them was the greatest Sorcerer who ever lived. His name . . . but I really shouldn39。t tell you his name. I39。m sure he39。d be very cross if I did. This Sorcerer passed by the Princess39。s bier . . . that39。s a I know, I know, Ian. Go on! Suddenly he frowned and leaned over her pale form. 39。What is this?39。 he thunde red. 39。Why was 1 not told?39。 Everyone was very concerned. This Sorcerer was a dangerous man. One time when someone insulted him he made a spell that turned everyone39。s heads backwards so they had to walk around with rearview mirrors. No one knew what he would do if he got really angry. 39。This Princess is wearing the Star stone,39。 he said, and drew himself up and frowned a ll around as if he were surrounded by idiots. I39。m sure he thought he was and maybe he was right. Because he went on to tell them just what the Star stone was, and what it did, something no one there had ever heard before. And this is the part I39。m not sure of. Because, though everyone new the Sorcerer was a wise and powerful man, he was also known as a great liar. He said that the Star stone was capable of capturing the essence of a person at the moment of her death. All her wisdom, all her power, all her knowledge and beauty and strength w ould f low into the stone and be held there, timelessly. In suspended animation, Radiant breathed. Precisely. When they heard this, the people were amazed. They buffeted the Sorcerer with questions, to which
