Triangle at Rhodes by Agatha Christie

While vacationing on the island of Rhodes, Poirot observes a tense romantic triangle forming between a glamorous woman, her jealous husband, and a charming outsider. When murder strikes, the initial suspects appear obvious—but Poirot sees beneath the surface. With his trademark precision, he untangles motives driven by passion, manipulation, and disguise. The story is short but rich in atmosphere and psychological insight. A clever whodunit where nothing is quite as it seems.
