His Last Bow
In the introduction to Arthur Conan Doyle's short story collection "His Last Bow", Dr. Watson states that Sherlock Holmes has retired to a small farm upon the Downs near Eastbourne. In "His Last Bow" itself, Holmes states that he "lives and keeps bees upon the South Downs". Furthermore, the short story "The Lion's Mane" is about a case which Holmes solves whilst living there.
