New Scotland Yard's Black Museum is a repository for pieces of evidence from some of the most celebrated and grisly of crimes, from knives and guns to Dennis Nilsen's cooker and the poison pellet which killed Georgi Markov. This book presents an array of famous cases, together with a history of the museum, the Yard itself, and various methods of identification such as finger-printing. Whether focusing on Jack the Ripper (and seeking to demolish some of the fanciful theories about the Ripper's identity) or documenting the horrors of Dennis Nilsen's merciless crimes, the text is illustrated with pictures from the enormous police archive and the museum's memorabilia.
