Triangle at Rhodes: a Hercule Poirot Short Story

The story's resolution felt so satisfying yet unexpected. I wonder what inspired the author to develop this particular twist and how she managed to keep the reader guessing.

Poirot's characteristic logic is always impressive, but sometimes it feels almost too perfect. Was that intentional to highlight his brilliance or a bit contrived?

The exotic locale adds a layer of intrigue, but I'm curious whether Christie chose Rhodes for the scenery or for the story's themes of deception and hidden truths.
