Murder on the Orient Express, by Agatha Christie

While I was in Paris, jet lag woke me up early one morning at around three, and so I read this entire novel in the wee hours of the morning. I knew the ending, of course, because there are references to it everywhere; it's like Rosebud. But I enjoyed seeing how it played out nonetheless, and the ultimate resolution was a surprise after all in several small ways. I don't want to say too much, in case someone, my some miracle, isn't spoiled. But anyway, a very fun and quick read, even in the pre-dawn hours.
