Ever since his creation, Sherlock Holmes has enthralled readers. Our perception of him and his faithful companion, Dr Watson, has been shaped by a long line of film, TV and theatre adaptations. This richly illustrated book, compiled by Alex Werner, Head of History Collections at the Museum of London, is an essential guide to the great fictional detective and his world. Using the museum's unrivalled collections of photographs, paintings and original artefacts, it illuminates the capital city that inspired the Sherlock Holmes stories, in particular its fogs, Hansom cabs, criminal underworld, famous landmarks and streets. Accompanying the landmark exhibition at the Museum of London, the first since 1951, this book explores how Arthur Conan Doyle's creation of Sherlock Holmes has transcended literature and continues to attract audiences to this day. Authoritatively written by leading experts, headed by Sir David Cannadine, this thought-provoking companion sheds new light on the famous sleuth and reveals the truth behind the fiction, over 125 years after the first Sherlock Holmes story was written.
