Evil Under the Sun (1982)

A locked-room murder mystery where everyone has a reason to want the victim dead. Good thing Hercule Poirot (Ustinov) is vacationing at the small island resort where the murder occurred.

It's a fun little case, buoyed considerably by the scenes where the proprietress (Maggie Smith) pitches her suspicions to Poirot. Hurt only somewhat by the fact that I was able to guess the culprit and the method way before they were revealed by Poirot.
