Publisher's Synopsis
The Sign of the Four is the second Sherlock Holmes book. Its complex plot involves service in East India Company, India, the Indian Rebellion of 1857, a stolen treasure, and a secret pact among four convicts and two corrupt prison guards. It presents Sherlock Holmes' drug habit and humanizes him in a way that had not been done in A Study in Scarlet. It also introduces Doctor Watson's future wife, Mary Morstan.
