The Adventure of the Second Stain

The Adventure of the Second Stain is a detective short story by Arthur Conan Doyle, first published in 1904 and part of the Sherlock Holmes canon. It belongs to the later Holmes stories and presents a case that Watson refers to as previously unrecorded, so the focus stays on Holmes, Watson, and the process of piecing together a mystery rather than on a large cast or a long build-up.

It suits readers who like classic detective fiction in a compact form, especially if they already enjoy the Sherlock Holmes world. The story gets to the point quickly, which makes it easy to pick up without committing to a long novel. If Doyle’s style works for you, this is the kind of Holmes story that leans on careful observation, restrained dialogue, and a case that unfolds through small details.
