The letter was written by a total stranger who signed herself Joanna Marshall. It looked pretty much like a hundred other fan letters, forwarded from the publishers' office. But even after Eve Endicott read it more than once and when she had answered it, she found she still could not forget it. Tad Benson, who published her books, advised her that it was none of her business how old Joanna Marshall was or why she seemed to be a prisoner in her father's house. Tad said Beaumont Marshall was an artist living in the same Connecticut community as himself -- thought by those who knew him to be more than eccentric. Tad had never heard about a daughter but knew Marshall's wife had left him years ago. "Couple of psychopaths, probably," Tad said. "Don't get involved with anything like that." But Eve had to know the rest of the story.
