Lenore felt a thrill of secret pleasure go through her, a feeling of possessing a delicious secret, a delightful sensation of reckless gaiety, of life stirring throughout the sleepy ship, of a web of secrets and countersecrets hidden from everyone but this unconcerned observer. She walked back down the corridor, balancing the tray. When a little splashed over the rim of the tall glasses, she took a sip from each, tasting the sweet, cold liquid in her throat. When she came to the head of the stairs, she realized that she did not even know her telepath's name. Closing her eyes, she said very slowly and distinctly inside her head, "Mr. Fairheart?" Instantly his thought was with her, overpowering, as breathless as an embrace. "Where are you?" "At the head of the central stairs." "Down you go." She went down the stairs, through more corridors, down more stairs, while he guided her steps. Once she paused to sip again at each glass when the liquid splashed as she was going down. The ice tickled her nose and made her sneeze. "You live a long way down," she said. "I've got to be near my charges," he answered. "I told you I work on the ship; I'm a zoologist classifying any of the new specimens of extraterrestrial life they're always picking up. And I always get stuck with the worst quarters on the ship. Why, I can't even call all my suite my own. The whole front room is filled with some sort of ship's gear that my steward stumbles over every meal time." She went on and on, down and down. "How many flights?" she wondered. "Two or twelve or twenty?" Now, why couldn't she remember? Only four little sips and her mind felt so cloudy. Down another corridor, and what was that funny smell? These passages were poorly ventilated in the lower levels; probably that was what made her feel so dizzy. "Only one more flight," he whispered. "Only one more." Down and along and then the door. She paused, conscious of rising excitement, conscious of her beating heart. Dimly she noticed the sign on the door. "You--you mean whatever it is you're taking care of is in there with you?" "Don't be frightened," his persuasive thought came. "It can't hurt you. It's locked in a cage." Then she slid the bolt and turned the handle. Her head hurt for an instant; and she was inside, a blue and silver shadow in the dim anteroom, with the tray in her hand and the books under her arm and her pulse hammering. She looked around the dim anteroom, at the spidery tangle of orange and black ropes against the left-hand wall; then at the doorway in the right-hand wall with the warm light streaming through. He was standing in the second room, one hand on the chair for support, the other extended toward her. For the first time he spoke aloud. "Hello, butterfly," he said. "Hello," she said. She smiled and walked forward into the light. She reached out for his hand. Then she stopped short, her hand pressed against an impenetrable wall. * * * * *
