This is ridiculously clever. At no point did I suspect what was going on - though, to be fair, this is pretty much always the case on the rare occasions that I read a mystery. I'm always stumped. So many unpleasant people! And they pretty much all deserved what was coming to them. Not feeling sorry for any of them, I was riveted. There is, it must be said, some really unfortunate racism to side-eye in this book (definitely a product of its time), and that was disappointing. The puzzle itself, however, was very well executed.

I've only ever read one other Christie book, which I liked but wasn't too engaged by. After this I might be more inclined to try another.
