In telling of his most interesting cases he takes the reader behind the scenes and shows just how the C.I.D. man goes to work. He is the man who caught Crippen." "Then there was the most terrifying killer of all time - Jack the Ripper, the phantom-like friend who stalked the streets of Whitechapel and terrorized the whole of the East End of London. Inspector Dew was the first policeman on the scene of one of these ghastly murders, and he tells how clue after clue was followed up and how near the police were to laying their hands on the probable murderer.
