How did a woman holding a pistol in her right hand manage to shoot herself in the left temple? What was the link between a ghost sighting and the disappearance of top secret military plans? How did the bullet that killed Sir Gervase shatter a mirror in another part of the room? And who destroyed the eternal triangle of love involving renowned beauty, Valentine Chantry?. Hercule Poirot is faced with four mystifying cases - Murder in the Mews, The Incredible Theft, Dead Mans Mirror and Triangle at Rhodes - each a miniature classic of characterisation, incident and suspense.
