In an apparent crime of passion, beautiful Arlena Stuart is found strangled on the beach of an exclusive English holiday resort where Poirot happens to be on holiday…

I had a faint sense of déjà vu throughout this one, which was a little distracting, but it did help point me in the direction of whodunnit. Not how it was done though (not even close), and it was a satisfyingly clever solution with a number of unexpected twists.

Poirot was on fine form as usual - yet another of his holidays interrupted by a murder (at this point, what are the odds of him going on an uneventful holiday?). But honestly, the highlight of this one is some of the descriptions, with one of the characters described as “pretty in a negative way” (what does that even mean?) and women hikers are described as “hefty young women in shorts” (ouch).

Poirot engages his little grey cells whilst on holiday in this clever, twisty murder mystery.
