The greatest mystery of Doyle's life is how the creator of Sherlock Holmes that "perfect reasoning and observing machine" would eventually champion fey phenomena like seances and fairies, so that by his 1930 death at age 71 he was considered "hopelessly crazy." Doyle transcended his artistic Irish-Catholic family to become an archetypally "British" doctor, adventurer in Africa and the Arctic, two-time parliamentary candidate, and knighted novelist. Only after his son's death during World War I did Doyle's unconventional, inquisitive imagination come unhinged. In Teller of Tales: The Life of Arthur Conan Doyle mystery writer Stashower pieces together clues from his subject's iconoclastic life to create a gripping, sympathetic bio that proves that Doyle was anything but elementary.
