Diogenes Club

Relation to British Secret Service

The original Sherlock Holmes stories give no indication that the Diogenes Club is anything other than a quiet retreat. Later writers, however, developed the idea that it served as a front for the British Secret Service, possibly inspired by Mycroft Holmes's role as the indispensable brain-trust behind the government in "The Adventure of the Bruce-Partington Plans" (1908). This notion was popularized by the 1970 film The Private Life of Sherlock Holmes and has since appeared in many pastiches and the TV series Sherlock.

In other media

The Diogenes Club appears in numerous works, most of which assume its connection to the British Secret Service. In Carter Dickson's 1935 novel The Unicorn Murders, Secret Service detective Sir Henry Merrivale references the club. The 1994 Doctor Who novel All-Consuming Fire, a crossover with Sherlock Holmes, features the club and mentions Kim Newman's character Charles Beauregard; a 2008 follow-up audio adventure is titled The Adventure of the Diogenes Damsel.

Guy Ritchie's 2011 film Sherlock Holmes: A Game of Shadows includes a mention of the club. It also appears in Nicholas Meyer's 1974 novel The Seven-Per-Cent Solution, Alan Moore's The League of Extraordinary Gentlemen: Black Dossier, the computer game Sherlock Holmes: Case of the Rose Tattoo, the comic Predator: Nemesis, and Neil Gaiman's short story "Closing Time" from Fragile Things. Kim Newman's Anno Dracula portrays the club as a headquarters for secret government decision-makers, with its silence rule serving as a security measure.

Philip José Farmer's The Other Log of Phileas Fogg claims the real Diogenes Club was the Athenaeum Club, with Conan Doyle changing the name. In the BBC series Sherlock episode "The Reichenbach Fall", Watson visits the club, is silenced for talking, and is escorted to the Stranger's Room by bouncers.
