To which county in England did Sherlock Holmes retire?

Sherlock Holmes retired to Sussex, settling on a small farm on the Sussex Downs and taking up beekeeping. The detail comes from Arthur Conan Doyle’s later Holmes stories, especially “His Last Bow,” in which Holmes has withdrawn from his London detective practice but returns temporarily to help Britain during wartime.

The retirement is not presented as a precisely dated event. References indicate that Holmes had moved to the Sussex countryside by no later than 1904, when “The Adventure of the Second Stain” mentions his retirement retrospectively. His country life is quieter but not entirely free of mysteries: “The Adventure of the Lion’s Mane” takes place during this period and has Holmes investigating a case himself.

Sussex is sometimes confused with Devon because Devon is the setting of much of The Hound of the Baskervilles, including Dartmoor-inspired scenery. The retirement location is specifically associated with the Sussex Downs, near Eastbourne in Watson’s account. Beekeeping became one of the character’s defining late-life occupations and later inspired titles such as The Beekeeper’s Apprentice.
