Poirot's Last Warning | A Hercule Poirot Mystery

Three words. Red ink. No signature. No return address. When Hercule Poirot receives a chilling anonymous warning — STOP. OR ELSE. — he doesn't even know what he's supposed to stop. Hours later, Inspector Japp calls: Sir Edmund Voss, a retired government cryptographer, has been found dead in his locked study at the Athenaeum Club. A cipher disk in his hand. Papers burned in the fireplace. And a death that looks like a heart attack... but isn't. As Poirot begins to pull at the threads — a composed widow with still hands, a decorated soldier with trembling ones, a Swiss diplomat with a suspiciously perfect alibi, and a young woman who built a filing system no one else could read — he finds himself circling something buried deep in the shadows of 1930s Europe. A codename. A betrayal. And a secret that someone was willing to kill to keep. This is an original Hercule Poirot fan fiction mystery, narrated in full. Set in London, 1938.
