Back in the days when I was really into Agatha Christie, I decided I really only liked her Hercule Poirot mysteries. After reading this, I remember why. They have greater complexity (thanks to Poirot's little grey cells) and fewer boring society details than Christie's other mysteries. I really enjoyed reconnecting with M. Poirot in this story. What's really cool is that I guessed who the murderer was right at the start, doggedly stood by my first guess, and I turned out to be right! That's never happened for me before in one of Agatha's books.
