"The old man had died quite naturally although they did find an oddly knotted piece of string next to his pillow. Still, they dismissed it until the normally sensible housekeeper told an incredible story of the beautiful woman who had walked through a wall, through a door where no door was, to get into the old man's room. None of this bothered Edward Stevens. He was too busy editing a book on nineteenth century murders. That was until he came to a photograph of a murderess, who was guillotined in 1861. It was a clear picture of a beautiful woman, whom Stevens immediately recognized. She was his wife!"--BOOK COVER.
