The Sherlock Holmes Companion contains all the necessary information to illuminate the great detective's work, from the early canon to the more recent incarnations of Holmes by Benedict Cumberbatch and Robert Downey Jr. Including chronological plot summaries of every single story, compact biographies of Holmes, Watson, Moriarty, and of course Conan Doyle himself - whose own life and preoccupations are of intrigue themselves. All of this alongside contemporary interviews with those who have brought the great detective to life on stage and screen.

If you want to know the variety of firearms toted by Holmes, when he first took to sporting a deerstalker, when Roger Moore played Holmes or Robert Duvall Watson, how Mark Gatiss is on both sides of the camera in Sherlock then you will find the answers here.

Illustrated throughout with period engravings, attractive theatre posters and book jackets as well as modern-day location shots and stills from TV and film adaptations. Now fully updated, this is a compendious guide to all the stories, their author and the enigmatic pipe-smoking creation at their heart.
