The New Revelation marks Arthur Conan Doyle's formal declaration of faith in spiritualism. Written as a pamphlet, it offers a passionate introduction to the philosophy and evidence he believed proved the existence of the afterlife. This work is not just a personal manifesto but a challenge to skeptics and an invitation to truth seekers. It became the cornerstone of Doyle's later spiritualist writings.

Sir Arthur Conan Doyle (1859–1930) was a Scottish author, physician, and spiritualist best known for creating the legendary detective Sherlock Holmes. Born in Edinburgh, he studied medicine at the University of Edinburgh, where his storytelling talent began to emerge alongside his scientific education. Though initially practicing as a doctor, Doyle turned to writing to support himself, eventually achieving worldwide fame with the publication of A Study in Scarlet in 1887. Beyond detective fiction, he explored historical novels, science fiction, and supernatural themes, notably in the Professor Challenger series. A passionate advocate for justice, he was involved in several real-life legal investigations. In his later years, Doyle became deeply involved in spiritualism, dedicating much of his time and writings to life after death. His legacy endures as one of the most influential figures in literary history.
