The Man with the Twisted Lip
The Musgrave Ritual
The Adventure of the Cardboard Box
The Adventure of the Blue Carbuncle

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.
