I get why Agatha Christie said this was her favorite. I enjoyed it greatly. The dialog was intriguing and insightful. The characters were very well-written and are probably the best and most vivid characters I have ever witnessed in a Christie book. Each and everyone one of them was interesting. As for the final indictment, the hints were there all along it's almost obvious who did it. But they're the kind of clues that you don't realize who they're pointing to until the very end, and then you blame yourself for not being smart enough. I predicted some things. Some clues were in plain sight it's almost frustrating that the police couldn't connect the dots earlier. But still, I kept questioning and changing who I thought did it almost till the very end. The ending was great and I think this book will also be one of my favorites.
