Wishing for a quiet holiday free from crime, Poirot goes to Rhodes during the low season in October where there are but a few guests. Aside from the young Pamela Lyall and Sarah Blake there is Valentine Chantry, a consciously beautiful woman who seems to swoon under the attentions of Douglas Gold. This is done at the expense of his own wife, Marjorie, a mildly attractive woman, and Valentine's husband Tony Chantry. This is the "triangle" that everyone observes, and it gets rather absurd with the two men vying for Valentine's favour. She seems to delight in the attention. Marjorie Gold soon wins the sympathy of many of the guests of the hotel as her husband is frequently in the company of Valentine, she confesses her own doubts about Valentine to Poirot. Poirot, however, warns her to flee the island if she values her life. The event comes to a head one evening, beginning when Gold and Chantry have a loud argument. Valentine and Marjorie return from a drive, and the former is poisoned by the cocktail her husband gives her. Gold is immediately suspected, as the strophanthin that kills Valentine is found in the pocket of his dinner jacket. Poirot notices otherwise, seeing that Chantry puts it in Gold's pocket just as everyone's attention is on his dying wife. Poirot gives this information to the police, and points out to Pamela Lyall that she was focusing on the wrong triangle. The real triangle was between Douglas, Marjorie and Chantry. Chantry and Marjorie were in love, but they could not get married as Douglas, a Catholic, would not consent to divorce. For this reason, Chantry and Marjorie decided to kill Valentine and ensure that Douglas was blamed for the murder. Also, Poirot's warning to Marjorie Gold was not because he feared she was a victim at risk of being murdered, but the opposite. He was warning her she would be caught, tried, and convicted as one of the culprits.
