The Case-Book of Sherlock Holmes (1927) is the final collection of Sherlock Holmes stories by Sir Arthur Conan Doyle, gathering twelve tales written in the author's later years. In these cases, the legendary detective and his faithful companion Dr. Watson confront some of their most peculiar mysteries: a suspected vampire in Sussex, a scientist who regains youth through a monkey serum, stolen crown jewels, and dark secrets hidden in English country houses. Notably, two stories are narrated by Holmes himself rather than Watson. Though considered uneven in quality, the collection showcases Doyle's enduring imagination and offers a final farewell to the world's greatest consulting detective.
