D. D. Home: His Life and Mission is a biographical work edited (and partly authored) by Arthur Conan Doyle, focusing on the famous 19th-century medium Daniel Dunglas Home. In this compilation, Doyle presents Home's extraordinary life story and the purported miracles attributed to him, framing Home as a pivotal figure in the spiritualist movement. The book covers Home's early demonstrations of psychic talents, such as levitation and communicating with spirits, which astonished even royal audiences. Doyle, a fervent spiritualist, provides commentary and context, defending Home's feats as genuine and emphasizing his "mission" to prove survival after death. Anecdotes of séances – tables rising, phantom hands, and accurate spirit messages – are detailed with both skepticism and belief in mind. By curating eyewitness accounts, letters, and his own insights, Doyle aims to solidify D. D. Home's legacy as a true apostle of spiritualism. His Life and Mission stands as a significant piece of Doyle's non-fiction, reflecting his commitment to documenting and vindicating the work of a man he saw as a "missionary" of the unseen world.
