The Musgrave Ritual

"The Adventure of the Musgrave Ritual" is a short story by Arthur Conan Doyle, featuring his fictional detective Sherlock Holmes. The story was originally published in Strand Magazine in 1893, and was collected later in The Memoirs of Sherlock Holmes. Unlike the majority of Holmes stories, the main narrator is not Doctor Watson, but Sherlock Holmes himself. With Watson providing an introduction, the story within a story is a classic example of a frame tale. It is one of the earliest recorded cases investigated by Holmes, and establishes his problem solving skills.
"The Adventure of the Musgrave Ritual" shares elements with two Edgar Allan Poe tales: "The Gold Bug" and "The Cask of Amontillado".
In 1927, Conan Doyle ranked the story at 11th place on his top 12 Holmes stories list. The story did better in a 1959 chart produced by The Baker Street Journal, ranking 6th out of 10.
