This is the story of a power struggle between two men - one fictional, and one real. In one corner is the master of crime – the greatest detective who never lived, Sherlock Holmes. In the other is writer, physician and spiritualist leader Sir Arthur Conan Doyle. Lucy Worsley explores the extraordinary love-hate relationship between author and creation.
