The Sign of Four

This mystery novel follows Sherlock Holmes and Dr. Watson as they aid a young woman whose father vanished ten years prior. When she begins to receive annual gifts of pearls, she receives an invitation to meet her benefactor and asks for Holmes and Watson's help. In the investigation that follows, they encounter Indian treasure, a wooden-legged criminal, a loyal dog, and even a love story. With a dense fog looming over London and a sense of melancholy lingering over Holmes, the thrilling twists and turns of the case make for an engaging read.
