The Stark Munro Letters is a novel by British author Sir Arthur Conan Doyle first published in 1895 by Longmans, Green & Co. in London, England.

The book is heavily autobiographical, depicting Conan Doyle's relationship with his parents and his emerging interest in spirituality.

This was shortly after he had published "The Final Problem", the story in which he killed off Sherlock Holmes; in writing The Stark Munro Letters he was attempting to expand his career in a more literary direction.

In a letter to his mother dated 23 January 1894, he wrote that "It will make a religious sensation if not a literary - possibly both.

"[2] As an epistolary novel it takes the form of twelve long letters written by J. Stark Munro between March 1881 and November 1884 and sent to his friend Herbert Swanborough of Lowell, Massachusetts.
