By A. Conan Doyle.

The Sign of the Four (also known as Sign of Four) by Arthur Conan Doyler is the second Sherlock Holmes novel, after A Study in Scarlet. The plot involves service in India, the Indian Rebellion of 1857, a stolen treasure, and a secret pact among four convicts (“the Four” of the title) and two corrupt prison guards... and of course, Sherlock Holmes.
