This book is incredible, and one of my favorite Christie books I have read so far. It was the Christie book that got me hooked. Now I'm an Agatha Christie freak! ;) It's a great mystery. The plot will leaving you guessing the entire time, and in the end, you'll probably sit there with your mouth wide open in shock for awhile, and when you finally come to, your first words will be, "I NEVER SAW THAT COMING!" In a nutshell, the book is an absolute masterpiece.
