I recently read And Then There Were None, and like that Murder on the Orient Express is very clever. And though it was still a really enjoyable read, I'm not sure it was quite as good as ATTWN. The structure is a little more plodding - an interview a chapter for however many suspects there were, it was all rather too linear. But there is justice at the end, moral if not legal, and I'm quite surprised at how much more I enjoyed the character of Poirot than I did in the only other book with him I've read (The Mysterious Affair at Styles). Still, that was Christie's first book, and it's clear that she's improved since then - especially in pacing and character.

I don't usually read a lot of mysteries, but I think I may be hooked on her now...
