Sir Arthur Ignatius Conan Doyle (1859 - 1930) was a Scottish physician and writer who is most noted for his fictional stories about the detective Sherlock Holmes, which are generally considered milestones in the field of crime fiction. Following the death of his wife Louisa in 1906, the death of his son Kingsley just before the end of the First World War, and the deaths of his brother Innes, his two brothers-in-law (one of whom was E. W. Hornung, creator of the literary character Raffles) and his two nephews shortly after the war, Doyle sank into depression. He found solace supporting spiritualism and its attempts to find proof of existence beyond the grave. In particular, according to some, he favoured Christian Spiritualism and encouraged the Spiritualists' National Union to accept an eighth precept - that of following the teachings and example of Jesus of Nazareth. He was a member of the renowned supernatural organisation The Ghost Club.
