The narrative begins when a penurious and eccentric miser named Joseph Riggs is found dead in his study with a pistol wound to the temple. His nephew, Robert Fletcher, had visited him the previous afternoon and parted from him after a violent quarrel over Fletcher's engagement to a dowerless young woman named Lilian Markham. During this bitter dispute, Riggs forced Fletcher to take his gold watch and a bundle of bearer bonds as his entire inheritance, declaring he would leave him nothing else. When the house is inspected the following morning, the front door is unlocked, blood pools are found in the hall, and the gold watch is missing.
Because of the open hostility between uncle and nephew, local suspicion falls instantly on Fletcher, who is arrested on charges of robbery and murder. Seeking justice for the young man, a kind-hearted clergyman named Mr. Foxley and the distressed Lilian Markham seek out Dr.
John Thorndyke. Thorndyke agrees to investigate the circumstances surrounding the death of Riggs and the alleged theft. The plot unfolds through meticulous observation of physical evidence, uncovering hidden motives, alibis, and unexpected developments that challenge the apparent guilt of the accused nephew. As the forensic analysis deepens, the narrative reveals the subtle mechanics of the crime, the complex relationships between the characters, and the true identity of the perpetrator. The story moves toward a resolution where Thorndyke sifts through material clues to unravel the mystery and restore the innocent to freedom, bringing a satisfying conclusion to a dark family tragedy.
