This is actually one of my favourite Christie novels. The main reason for this is that it contains all of the classic ingredients that really make one of her novels; a fabulous array of characters, especially the terrier dog, Bob, an excellent plot that will keep you guessing to the very end, a wonderful setting and, of course, Hercule Poirot with all his foibles to solve the mystery. A must-read for any mystery fan, and as the video starring David Suchet is equally brilliant, I recommend you make sure you own, or have at least seen and read, both.
