The list was incredible. The book looked thin enough, but there were over a thousand pages in it. It was full of information. Too full. She still didn't understand how it had got to the library shelves but at least one thing was clear. James must have started reading it that very first day when he had got it for her. He must have realized what it was and hidden it so that he might have a chance to study it. _Hypnotism Direct_--that had been Reardon. _Hypnotism at Second and Third Removes_--that had been Bill acting on his office, herself on her bridge group, Barbara on her college mates. The _Reverse Electromagnetic Effect_--that had been all those weird happenings over television. She stared at her bound and gagged son. If it hadn't been for that postcard and if she had gone for the book herself instead of sending James, this wouldn't have happened. As it was the book had turned him into a little monster. Her own child! And she had thought that he was becoming such a fine upstanding young man of late! Had he hypnotized her into thinking that? Probably. Just as he had tried to hypnotize her again before. Let her untie his hands and he'd snap his fingers and in a moment her eyes would glaze.... She shuddered. She couldn't let him loose. But she couldn't leave him there like that either. You can't keep a child bound and gagged for the rest of his or your natural life. You can't do it for more than a few hours. Sooner or later, even if it were only to permit him to eat, she'd have to untie him and then.... She stared down at the book in her hands. How _had_ it got here? Had some irresponsible person in the year 2083 or so read it, just as James had done, and then gone around hypnotizing people at random? Perhaps he had hypnotized someone who could operate a time machine and the bewildered scientist had sent it backward in time. She caught herself up short. Such speculations, to a practical woman like Carrie, were silly. The important thing was that here, before her, were a thousand pages of useful but dangerous information--how dangerous she could only guess. So far James had done little actual harm but let his resentment be aroused, let him want really to revenge himself on some one, and he'd be the most dangerous human being alive. Her eyes ran down the list of chapters again. They seemed endless. _Hypnotism by Gesture_--_Hypnotism by Mechanical Means_--_Hypnotism by Autosuggestion_--_Posthypnotic Suggestion_--and finally a whose series on _Erasure_. _Erasure_--that sounded interesting. What were you supposed to erase? There were different sub-headings--_Erasure of Susceptibility_--_Erasure of Specific Directives_--_General Erasure_. She sat down and read with a concentration she had not shown in years. Two hours later she thought she knew what to do. First she did what the book said was necessary to protect herself. Then she said, "James, look at me."
