Annie clouded up. For a second, he thought she was going to erupt, and flinched. She saw that...and got control of herself with an visible effort. She took three deep breaths, each longer than the last, and her features became serene.All at once it seemed totally clear to Mike that she was right and he was nuts - that his ingenius theory was nonsense, childish, fantasty bullshit. His conviction evaporated, and he was ashamed. He felt his cheeks grow hot, groped for words with which to backtrack -"I have to admit I have no better explanation for the the facts," Annie said slowly.Again, Mike did an emotional instant 180. "Holy shit -"She held up a hand. "I am going to think now. Very hard, for a long time. You will be as quiet as possible while I do." She got up from the computer, went to the bed, and lay down. "Think yourself, or read, or play games with the headphones on, or go Topside if you like." She clasped her hands on her belly, closed her eyes and appeared to go to sleep
