The Baker Street Irregulars
The Baker Street Irregulars is an organization of Sherlock Holmes enthusiasts founded in 1934 by Christopher Morley. As of 2015, the nonprofit organization had about 300 members worldwide.
The group has published The Baker Street Journal, an "irregular quarterly of Sherlockiana", since 1946. Members of the society participate in "the game" which postulates that Holmes and Doctor Watson were real and Sir Arthur Conan Doyle was merely Watson's "literary agent".
