Plot summary

(may contain spoilers - click on expand to read)

Poirot has been asked by a friend, who is the director of the Northern Union Insurance Company, to investigate the case of a middle-aged man who died of an internal haemorrhage just a few weeks after insuring his life for fifty thousand pounds. There were rumours that the man – Mr Maltravers – was in a difficult financial position and the suggestion has been made that he paid the insurance premiums and then committed suicide for the benefit of his beautiful young wife.

Poirot and Hastings travel to Marsdon Manor in Essex where the dead man was found in the grounds, with a small rook rifle by his side. They interview the widow and can find nothing wrong. They are leaving when a young man, Captain Black, arrives. A gardener tells Poirot that he visited the house the day before the death. Poirot interviews Black and by using word association finds out that he knew of someone who committed suicide with a rook rifle in East Africa when he was out there. Poirot realises that this story, told at the dinner table the day before the tragedy, gave Mrs Maltravers the idea as to how to kill her husband by making him demonstrate to her how the African farmer would have put the gun in his mouth. She then pulled the trigger and the unsuspicious local doctor certified a natural death. Mr Maltravers is then seen by a maid in the garden. She thinks that it was just a mistake, but then in the living room a strange thing happens. The lights suddenly go out and Mrs Maltravers clasps Poirot's hand. Mr Maltravers suddenly appears in the room, his index finger glowing and pointing at Mrs Maltravers' hand, which is covered in his blood. She is scared to death and confesses. Poirot explains that he hired a man to impersonate Mr Maltravers and turn off the lights. When Mrs Maltravers grabbed Poirot's hand, he put fake blood on hers. The man applied phosphorescent to his finger to make it glow and pointed to the woman's hand, which was covered in fake blood. She is terrified and confesses.
