A shocking account of the savage world in which Sherlock Holmes operated. The crimes of The Ripper; Conan Doyle's knowledge of the killer's identity; the methods employed by criminals, and of their pursuers; the harrowing truth about Holmes' drug abuse, and of his gang of 'street arabs', the long-lost crime monographs by the Baker Street sleuth; and much more, this book tells the true story of Holmes' gas-lit and sinister criminal world. "Victorian society was violent & exploitive..., footpads and garrotters stalked the streets of the City...beggars were rife.".
