Miss Marple: The Four Suspects, A short story by Agatha Christie. Narrated by Juliet Stevenson.

In this classic short story, a retired spy named Dr. Rosen is responsible for bringing down a super-secret German society. He's convinced the members of the organization that escaped arrest will be out for revenge, and his life is in danger. To evade retribution, he moves to England and sets up a small household in King's Gnaton. But as fate will have it, a fall and a broken neck will bring about his death. Though no one in the house seems to be the likely killer, Sir Henry Clithering enlists the help of Miss Marple to analyze the evidence and uncover which of the four suspects is guilty of murder.
