Poirot is asked for assistance by a young lady, Diana Maberly. She was engaged to marry Hugh Chandler for over a year but he has broken it off as he thinks he is going mad. There is a history of insanity in the family, with his grandfather and a great aunt being afflicted, and his father, Admiral Chandler, has insisted his son leave the Navy before his condition gets worse but the reason was hidden under the pretext of having to manage the family country estate – a reason no one believed, including Colonel Frobisher, a family friend and Hugh's godfather. At Poirot's prompting, Diana admits that there have been some unusual occurrences on nearby farms with the throats of sheep cut and the like but insists it has nothing to do with the situation. The Admiral refuses to let a doctor see his son.

Poirot travels with Diana to the family seat of Lyde Manor where he meets the people involved. Hugh strikes Poirot as a fine young bull of a man. He learns further details of the history of insanity in the family from Colonel Frobisher, including Hugh's grandfather who was committed to an asylum. Poirot learns that Hugh's mother died when he was ten years old in a boating accident when she was out with the Admiral, and that she was once in love with Frobisher before he went off to India with the British Army. When he came home he learned she had married Admiral Chandler, however this incident did nothing to lessen the ties of friendship between the two men. Poirot forces Frobisher to tell him more details of the incident with the sheep and finds out that on the night concerned, the Admiral found his son in bed with blood on his clothes and blood in the washbasin but Hugh remembered nothing of what he had done. Poirot questions the Admiral who has aged immensely since these incidents started and who feels that breaking the engagement is best for everyone, remarking that there will be no more Chandlers at Lyde Manor after he and his son have died.

In questioning Hugh, Poirot hears of his dreams which always seem to include elements of hydrophobia. He also suffers from hallucinations and has one while speaking to Poirot of seeing a skeletal figure in the garden. Poirot however is convinced that Hugh is sane and begins his investigations, asking Diana to arrange for him to spend the night in the manor. He searches Hugh's room and also makes a trip to a local chemist, supposedly to pick up a toothbrush.

That night, Hugh somehow manages to get out of his locked room and is found outside Diana's room, a bloodied knife in his hands from having killed a cat. Hugh recovers consciousness and tells the others he intends to go out shooting rabbits. It is clear that his real intention is to commit suicide in the woods with a shotgun and therefore save himself and the others further pain. Poirot stops him and tells them all that Hugh is being set up to commit suicide. He is being poisoned with atropine sulphate, an alkaloid produces hallucinations, double vision, dryness of throat and difficulty in swallowing--all symptoms which Hugh had experienced. It is being given to Hugh as part of his shaving cream and thereby continually entering his system with each day's application. Poirot had taken a sample of the cream for testing and had confirmed it. As to who is responsible ... Poirot reveals that it in fact Admiral Chandler. He had been using eyedrops containing atropine sulphate. By going to several chemists, he had obtained a large quantity of eyedrops from which the alkaloid could be extracted. As for Chandler's motive, Poirot asserts that it is indeed the streak of madness in his family which surfaced when he realised that Hugh was not his own son but the son that his wife had with Frobisher. He had recognised a characteristic head movement Hugh had inherited from Frobisher and probably extracted the truth from his wife. He then planned the killing of his wife in the boating incident and then set about to drive Hugh to commit suicide. Poirot was led to this conclusion from the fact that Chandler had blocked Hugh from seeing a doctor who could have treated him.

The Admiral, "the last of the Chandlers", dismisses Poirot's deductions as "a lot of nonsense" but then takes a shotgun and tells the others that he is going rabbit shooting. He is last seen entering the woods with the gun, and a shot is heard.



Research notes[]

The Chandler family has a tradition of joining the Navy, which started after Sir Gilbert Chandler sailed with Sir Walter Raleigh.
