"How we love to argue over the _names_ of things!" he answered gravely. "I don't care what you call the influence or obsession that threatens this lady. I ask, What do you propose to do about it? Do _you_ believe that Mrs. Wells will die tomorrow night? Do you?" Owen moved uncomfortably on his chair, frowned, snapped his fingers softly and finally admitted that he did not know. "Ah! Then is it your idea to wait without doing anything until tomorrow night comes, and see if Mrs. Wells really does die at half-past twelve, and then, if she does, as the Vallis woman died, to simply say: 'It's very strange, it's too bad!' and let it go at that? Is that your idea? Will you take that responsibility?" "No, certainly not. I don't mean to interfere with your plans. I told you I have left this matter entirely in your hands," answered the skeptic, his aggressiveness suddenly calmed. "Very well. Take my word, doctor, fear is terribly destructive, it may cause death. Listen to this case, cited by a French psychologist." He turned over the pages. "Daughter of an English nobleman, engaged to a man she loves, perfectly happy; but one night she is visited, or thinks she is, by her dead mother who says she will come for her daughter the next day at noon. The girl tells her father she is going to die. She reads her Bible, sings hymns to the accompaniment of a guitar, and just before noon, although apparently in excellent health, she asks to be helped to a large arm chair in her bedroom. At noon exactly she draws two or three gasping breaths and sinks back into her chair, dead. That shows what fear will do." But his adversary was still unconvinced. "What does that prove? Do you think you could have saved this young woman if you had been in charge of the case?" "Perhaps. I hope to save Mrs. Wells." "How?" Leroy hesitated, frowned with a nervous squinting, as if he were trying to solve a baffling problem. "How? I wish I could tell you, doctor, but you would not understand. That is the sad part of my work, I am all alone." His eyes burned somberly, then he spoke with intense feeling.
