The Valley of Fear

Despite his large output of historical fiction (The White Company, Micah Clarke), Sir Arthur Conan Doyle is remembered almost solely for his creation of the detective Sherlock Holmes. After being knighted in 1902 for his service in (and outspoken support of) the Boer War, Doyle became fascinated by spiritualism and mediumistic phenomena - interests he shared with his friend Harry Houdini.
