A resort town in the UK in the fifties. A collection of characters – couples, singles, children. And Hercules Poirot, whose reputation precedes him, and many jokes are made about him being somewhere that there isn’t a murder. And then… there’s a murder.
This is pretty standard Christie. Very much of its time when it comes to attitudes and depictions of characters, there are the red herrings and confusing lines of thinking we’ve come to expect. And, of course, the murder is solved – along with some other strange happenings.
