To this day the name of Dr Crippen is universally recognised as one of the most infamous in the annals of crime and his notoriety is second only to that of Jack the Ripper. It was the job of one man to catch both Crippen and Jack the Riper. His name was Walter Dew. Dew was a detective constable in the Whitechapel Criminal Investigation Department throughout the Ripper investigation and famously the first officer at the scene of the horrific murder of Mary Kelly. His transatlantic chase and eventual capture of the fugitive Dr Crippen and his mistress Ethel Le Neve made him the most celebrated detective in the world. Even today his name is widely known and he has featured in several films and works of fiction. Based on original research and using much hitherto unpublished material, Walter Dew: The Man Who Caught Crippen tells the full, extraordinary story of Dew's life, from his humble beginnings as a seed merchant's clerk to chief inspector at Scotland Yard in charge of the most celebrated murder investigation of the twentieth century.
