Arthur Conan Doyle was a British writer and physician, known as the creator of the great detective Sherlock Holmes. In his later years he became deeply devoted to Spiritualism.
In his youth, in 1884, he published the short story “J. Habakuk Jephson’s Statement,” based on a sailing ship whose crew had vanished, which helped spread the mystery of the Mary Celeste around the world. His novel The Hound of the Baskervilles, said by some to draw on legends of a black demon hound, is also told together with the black dog legends of Britain such as Black Shuck.
