The Adventure of the Red Circle

The Adventure of the Red Circle is a short story by Arthur Conan Doyle, first published in 1911 and part of the Sherlock Holmes canon. It belongs to detective and crime fiction, and it is one of the 56 Sherlock Holmes stories Doyle wrote. The story also appears in the anthology His Last Bow, so it sits comfortably within the larger Holmes collection. If you want a compact entry point into Holmes, this is the kind of story that gives you the familiar setup of clues, deductions, and a mystery that unfolds through careful observation rather than big spectacle.

It suits readers who like classic detective fiction, shorter reads, and stories built around methodical investigation. Fans of Sherlock Holmes will recognize Doyle’s familiar style here, while new readers can use it as a low-commitment way to see whether the character and the format work for them. Its closest home is the wider Holmes canon and the broader tradition of crime stories that rely on logic, atmosphere, and the slow reveal of a case.
