Jack the Ripper : the 21st Century Investigation. [signed] [first edition]

There have been countless attempts to solve the brutal murders committed more than 100 years ago by Jack the Ripper, but this most famous of British criminal cases finally benefits from a clear, professional eye to analyze the evidence with all the benefits of modern investigative techniques. Casting aside the rumors, fantasies, and urban legends which have haunted this case for so long, Trevor Marriott produces some startling results—while it has long been accepted that Jack the Ripper killed only five women, Marriott believes there were up to nine victims. Most astonishingly of all, a previously unconsidered suspect who also committed murders in America and Germany has been firmly put in the frame. All previous theories are refuted in what may possibly be the final word on the Ripper murders.
