Originally reviewed at Here There Be Books.I didn't really have any expectations for this, mostly because I'm only familiar with Christie's Poirot books and not much else. However, I was immensely satisfied to discover that this is a truly excellent book. I had a lot of fun reading it! The action and drama was kept high throughout the course of the plot, and the twist at the end was marvelously well-done. I didn't expect it at all-- in fact, I thought I had worked out the solution about halfway through, but I was completely wrong. I love it when mystery books do that; it makes reading them into a fun game.The characters were a bit harder to like, especially Tommy and Tuppence. They had a difficult time coming across as actual people, rather than pastiches of people. I don't think I ever really broke through that thinking, but I did cheer them on to "win," and I worried about Tommy when he was kidnapped, and I couldn't stop smiling after T&T got engaged (that's not a spoiler, is it? Surely everyone must know that they're married, right?).As I said before, I had a lot of fun reading this, and I'd easily recommend it to mystery fans, people who want to read something of Christie's besides Poirot/Marple, and those who are fans of inter-war English detective fiction.
