A fortune hunter expected home from a diamond mining expedition to South Africa turns up murdered, with his false hand missing. Suspects abound, including the fiancé of the dead man's daughter. But why was the adventurer murdered? And why did the killer steal his victim's wooden hand? This Edwardian murder mystery from the prolific Fergus Hume (The Mystery of a Hansom Cab) moves from the heart of the English countryside to the dark underbelly of London's criminal underworld.
