Sir Arthur Conan Doyle (1859-1930) was a British writer known chiefly for a series of stories featuring the brilliant detective Sherlock Holmes, including The Hound of the Baskervilles (1902). Conan Doyle was a long-standing member of the Society of Psychical Research, and was often asked to investigate and report cases of supernatural occurrences. In discussing his research of psychic science, he wrote, "My experiences with mediums, good, bad and indifferent, are probably as wide as those of any living man."
