Evil Under the Sun

Poirot is ordered by his doctor to spend a few weeks at a health resort in Devon, on the grounds that he is too fat and out of condition, and Hastings comes along for a holiday. In Devon they meet an old acquaintance, the fashion designer Rosamund Darnley. Before too long another guest (the rich, troublesome and flirtatious Arlena Stuart) is found strangled on the beach, and Poirot begins an investigation which proves to be one of the most challenging of his career, with suspects abounding. However, the detective is greatly helped by the parallels between Arlena's murder and the unsolved killing of another rich young woman a few years before.
