Adventure of the Bruce-Partington Plans

The Adventure of the Bruce-Partington Plans was originally published in The Strand Magazine in 1908 and later included in the 1917 collection His Last Bow. Written by Arthur Conan Doyle, the story features Sherlock Holmes and his brother Mycroft, focusing on the theft of top-secret government submarine blueprints from a London Underground track. It is regarded as one of the most significant tales in the canon, as it marks one of the few instances where Mycroft Holmes plays a pivotal role in a case involving national security.
