In the title work in this collection of novellas, Poirot and Inspector Japp collaborate on the investigation of a suspicious suicide. The supernatural is said to play in the disappearance of top secret military plans in The Incredible Theft — an incredible claim, indeed, as Poirot will prove. The bullet that kills Gervase Chevenix-Gore shatters a mirror in Dead Man's Mirror — just the clue Poirot needs to solve the crime. And, while basking on white Mediterranean sands, Poirot stares trouble in the face — the beautiful face of Valentine Chantry, now celebrating her fifth marriage — in Triangle at Rhodes.
