I have read all of the Poirot stories, and this is by far my favorite. Not only is it the perfect second bookend to the Poirot series (since the first Poirot story also took place at Styles), it is also the most intricate and brilliant of the Poirot stories. I have read Agatha Christie all of my life. I am usually able to pick up on some of her clues and figure out who the murderer might be. I confess, with this one, I could not. I loved re-reading it to discover the clues I had missed. The concept of the murderer who is brilliant enough to manipulate others into doing the job for him is extremely interesting. I wonder if Agatha Christie decided to kill off Poirot because she knew she could never write anything better than this. I believe this is the best of the best. I'm off to read it yet again
