In 1910 Chief Inspector Walter Dew became the most famous detective in the world after a transatlantic chase resulted in him capturing the American murderer Dr Hawley Harvey Crippen. This was the first time that wireless telegraphy had resulted in the arrest of a murderer and it was Dew's final investigation for Scotland Yard. After retiring from the Metropolitan Police and working as a private detective Dew began to write and in 1938 his autobiography I CAUGHT CRIPPEN was published. It subsequently became an important work for crime historians and has long been out-of-print. Dew's accounts of the Crippen case and his futile hunt for Jack the Ripper are the lengthiest ever written by a police officer closely involved in the investigations. The latter part of I CAUGHT CRIPPEN deals with a variety of other cases that Dew worked on, including the arrest of the international jewel thief Harry the Valet. THE ANNOTATED I CAUGHT CRIPPEN makes this classic work available again. It contains a full transcription of the original text, annotated with footnotes including additional material from a newspaper serialisation of Dew's memoirs that has never appeared in a book before. It also features appendices of Dew's other writings and articles written about the celebrated detective during his lifetime.
