Sherlock Holmes (Hound of the Baskervilles / Sign of Four / Study in Scarlet / Valley of Fear)

This 1929 collection assembles the four complete novels featuring detective Sherlock Holmes and Dr. John Watson.

The book provides a detailed look at Victorian social hierarchies and the anxieties of the British Empire.
