The Adventure of the Cardboard Box

This is a story from The Adventures of Sherlock Holmes III collection.

In this collection are four more individual cases for Mr. Sherlock Holmes, narrated by his faithful friend and admirer Dr. Watson. They dive into the opium dens of London in "The Man with the Twisted Lip," recall the curious history of "The Musgrave Ritual," come face to face with the grisly evidence contained in "The Cardboard Box," and go on a wild-goose chase in "The Adventure of the Blue Carbuncle." The powers of Sherlock Holmes prevail.
