The Sign of the Four

As a dense yellow fog swirls through the streets of London a deep melancholy has descended on Sherlock Holmes who sits in a cocaine-induced haze at 221B Baker Street.

Four years later she began to receive an exquisite gift every year: a large lustrous pearl. Now she has had an intriguing invitation to meet her unknown benefactor and urges Holmes and Watson to accompany her.
