Personally this one of the best Agatha Christie Hercule Poirot books I read. I loved it! It has so many plot twists and turns that I didn't see coming. It's refreshing to see a group of villains that could keep Poirot on his toes. But it's not your typical detective mystery novel either. It feels more like a spy novel. But I didn't mind it. I still loved it. You aren't really trying to figure out who did it. More like how to get them so to speak. So if you are looking for a typical murder mystery this might not be for you. But if you are looking for something intriguing and different then this is for you.
