"You're fortunate," he said, and he couldn't keep his eyes from straying back to her. "There are plenty of people around, both men and women, who can be donors. There must be some way to extract the hormones you need from the bloodstream. Our medical techniques may be crude but we'll manage. Keep that in mind." "I will--will you?" she asked, her lips parted, and it wasn't to breathe because she couldn't. He had the uncomfortable feeling that he knew exactly what she meant and it didn't have anything to do with what he'd said. Had she even been listening? Probably she hadn't. A pure male or female creature didn't exist but if one should come into being it would scarcely be human. To a human life mattered or death did but to the pure abstract creature there was only one thing of importance. He looked up to see her coming toward him. "I'm afraid," she said, clasping him to her, carefully keeping the tube free and open. And she was afraid--it was not dramatization. The studied glamour slipped from her face. "I don't want to be like this," she whispered. "But if it happens--help me, please." Her nearness was overpowering, and deadly. At length she drew away. Terror left her eyes--and it had been there, real though with other factors. Even in fear, and he was conscious of that and her deeper design, she had planned ahead against the time she might not be wholely human. It was something like to death to change drastically from a thinking reasoning person to someone who could react only to one stimulus. "We'll see that nothing happens to you," he said with weak assurance. "There may be a delay but it won't be long. We'll work it out." She was regarding him fixedly and he could see she was reverting. What he said wasn't penetrating. He cleared his throat. "You're as familiar with the place as any of us. Look around and see if you can find duplicate records. There may be a clue in them as to what the new preparations are for." Clarity returned to her face as he spoke. It would leave again and come back at decreasing intervals unless or until the hormone deficiency was corrected. How far she could descend and remain mentally unscathed he didn't know, nor did he want to find out. "Don't leave until I come back. Do you understand?" She smiled invitingly to show that perhaps she did understand what he said. He knew now that the sullen glamour was real, and terrifying. She couldn't help any of her responses. Docchi hurried out; so little time had elapsed she must be nearly normal. He thought of locking the door but there was no way to do that. The essence of a hospital was free access at all times, and so it was built. Besides, it wasn't a good idea to try to keep her in. Constraint might produce violent reaction. Docchi slanted the louvers so that the place looked vacant and let it go at that. The best he could hope for was that Maureen wouldn't think of leaving.
