Triangle at Rhodes

Poirot is staying at the Palace Hotel on the Aegean island of Rhodes. Among his fellow guests are an English couple, Commander and Mrs Chantry - and Poirot notices the beautiful Mrs Valentine Chantry flirting with other men. And then she is found dead, poisoned, and at once her husband is suspected. Is this a simple crime of passion, or is there some other motive at work? To solve the mystery, Poirot has to unravel a number of tangled relationships between those staying at the Palace Hotel. And he does not have the help of Hastings, who is not on the island.
