Stewart Evans is a policeman whose hobby is collecting true crime ephemera. When a second hand bookseller rang to ask him if he would be interested in a collection of letters from the Special Branch, he had no idea of the sensational revelation they would contain. One of these letters supplied an astonishing piece of infomation not contained in the decimated Scotland Yard files. The police had actually arrested and charged an American with the Ripper murders, but he escaped and disappeared in America. The Ripper murders ceased. The book reveals for the first time the identity of Jack the Ripper.
