Okay, it's a great murder mystery and a fun read.....However, upon finishing it I did forcefully throw the book across the room.
One of the things that Agatha Christie did well was turn the conventions of the genre on its ear. When you find out who actually committed the murder, you do feel a little cheated. It's tricky. I defy you to figure out the murderer before Hercule Poirot announces it.
