This is a fairly good mystery, the characters are interesting, Christie tries to keep you guessing, but the bottom line is, that this mystery is just not as good as her others. Although there are some interesting twists towards the end, the murderer's identity does not seem that surprising, and some details (one in particular) just seem sort of tacked on. This causes one to feel somewhat unsatisfied with the ending. Still, it was enjoyable for a light read, and it has some worthwhile aspects. One of the interesting things about this mystery is that it does not involve any of her usual detectives (Poirot, Miss Marple, Parker Pyne -- any others? I'm a hard core Poirot fan myself). You might try to find at your local library before you buy it, however, since you probably won't want to read it again.
