He scowled miserably at her. Her face was almost plain and the bandage, invisible or not, didn't improve her appearance any. How could he still feel that attraction to her? "Try Emmer," he suggested tiredly. "He'll find you irresistible, and he's even more savage than I am." "Is he?" She smiled enigmatically. "Maybe, in a biological sense. Too much, though. You're just right." He sat down on the bed. Again there was only one way of knowing what Emmer would do--and she knew. She had no concept of love outside of the physical, to make use of her body so as to gain an advantage--what advantage?--for the children she intended to have. Outside of that, nothing mattered, and for the sake of alloying the lower with the higher, she was as cruel to herself as she was to him. And yet he wanted her. "I do think I love you," she said. "And if love's enough, I may marry you in spite of everything. But you'll have to watch out whose children I have." She wriggled into his arms. The racial disparity was great and she had provoked him, but it was not completely her fault. Besides.... Besides what? She had a beautiful body that could bear superior children--and they might be his. He twisted away. With those thoughts, he was as bad as she was. Were they all that way, every one of them, crawling upward out of the slime toward the highest goal they could conceive of? Climbing over--no, _through_--everybody they could coerce, seduce or marry--onward and upward. He raised his hand, but it was against himself that his anger was turned. "Careful of the nose," she said, pressing against him. "You've already broken it once." He kissed her with sudden passion that even he knew was primitive. * * * * * There were no immediate results from the puppet performance and so it was repeated at intervals. After the third time, Firmon reported, coming in as Halden pored over the meager biological data he'd gathered on the unknown ancestor. Wild guesses mostly, not one real fact in all the statistics. After two hundred thousand years, there wasn't much left to work with. Firmon slouched down. "It worked," he said. "Got three a few hours ago." Halden looked at him; he had hoped it wouldn't work. There was satisfaction in being right, but he would rather face something less intelligent. Wariness was one thing, the shyness and slyness of an unseen animal, but intelligence was more difficult to predict. "Where are they?" he asked. "Did you want them?" Firmon seemed surprised at the idea. Halden sighed; it was his own fault. Firmon had a potentially good mind, but he hadn't been trained to use it and that counted for more than people thought. "Any animal smart enough to appreciate the value of a knife is worth study on that account. That goes double when it's a pest." "I'll change the cremation setting," said Firmon. "Next time, we'll just stun them."
