Shinichi was kept prisoner. The bodies of the kidnapper's two accomplices are found there, killed by an overdose of heroin. The police surmise that the kidnapper engineered their deaths by supplying them with uncut drugs. Further clues lead to the identity of the kidnapper, a medical intern at a nearby hospital, but there is no hard evidence linking him to the accomplices' murders. The police lay a trap by first planting a false story in the newspapers implying that the accomplices are still alive, and then forging a note from them demanding more drugs. The kidnapper is then apprehended in the act of trying to supply another lethal dose of uncut heroin to his accomplices, after testing the strength on a drug addict who overdoses and dies. Most of the ransom money is recovered, but too late to save Gondo's property from auction. With the kidnapper facing a death sentence, he requests to see Gondo while in prison and Gondo finally meets him face to face. Gondo has gone to work for a rival shoe company, earning less money but enjoying a free hand in running it. The kidnapper at first feigns no regrets for his actions. As he reveals that envy from seeing Gondo's house on the hill every day led him to conceive of the crime, his emotions gradually gain control over him and he ends up breaking down emotionally before Gondo after finally facing his failure.
