The Sign of Four

Who is sending the beautiful Miss Morstan a rare and priceless pearl each year? Holmes and Watson pursue Indian treasure and murders whose ominous trademark is "the sign of four".

When Sherlock Holmes is commissioned to investigate the meaning of this odd message, he and his trusted Watson have little idea of the scope of danger and intrigue they have been recruited to deal with.

Sir Arthur Conan Doyle was both a doctor and a believer in spirits, which may partly explain why his Sherlock Holmes is one of literature's most beloved detectives: Holmes always approaches his cases with the gentility and logic of a scientist, but the stories are suffused with an aura of the supernatural. Narrated by devoted assistant Dr. John H. Watson, Holmes's adventures were so addictive that fans protested the master deducer's "death" in 1893 and Doyle had to resurrect him.
