With the advantage of access to some of Scotland Yard’s most confidential papers, Donald Rumbelow  lays out all the evidence in the most comprehensive summary ever written about the Ripper. Rumbelow, a former London Metropolitan policeman, and an authority on crime, has subjected every theory – including those that have emerged in recent years – to the same deep scrutiny. He also examines the mythology surrounding the case and provides some fascinating insights into the portrayal of the Ripper on stage and screen and on the printed page. More seriously, he also examines the horrifying parallel crimes of the Düsseldorf Ripper and the Yorkshire Ripper in an attempt to throw further light on the atrocities of Victorian London.
