Book, Paperback Peter Costello Published in: 2006 Publisher: Running Press Language: English Arthur Conan Doyle did not rely on imagination for the amazing cases tackled by his hero, Sherlock Holmes, after all. Drawing on new research that follows the tracks the author left in the real world, Peter Costello details how Conan Doyle's fictional outpourings were the direct result of his hidden career as an amateur detective and criminologist. This fascinating book shows how many of Holmes's methods of deduction were actually methods his creator used to solve real crimes, and how real-life Scotland Yard had a Sherlock Holmes of its own: Arthur Conan Doyle. Eight pages of rare photographs are featured in this updated, revised edition of The Real World of Sherlock Holmes.
