Ranging from domestic killings to world-wide gangland contracts, this is an account of over 200 of the most controversial and intriguing unsolved murders of the last 150 years. It covers cases which continue to baffle the police and criminologists, as well as cases in which it seems likely that an innocent person was wrongly convicted, and sometimes executed. It describes famous and well-documented killings such as those of John F. Kennedy, Jimmy Hoffa, Julie Ward, and the Whitechapel murders, and also less well-known and often bizarre cases, including that of the pyjama girl in Australia, and Dr Straub and the rabbit-pie murder. James Morton is the author of "Gangland", "Bent Coppers" and "Lowspeak", and ghosted "Nipper" and "Mad Frank".
