Ingenious, charming, informative and full of delight. - The Times

Sherlock Holmes: The Unauthorized Biography blends what we already know of the great sleuth's career with carefully documented social history to answer the questions admirers have long puzzled over. Nick Rennison reveals for the first time Holmes's influence on the political events of late-nineteenth-century England and his connections to the British criminal underworld. It also brings to light his close friendships with key figures of the day, including Oscar Wilde and Sigmund Freud; and exposes the truth about his cocaine use.
