By Agatha Christie
Another well written mystery. I saw the movie a few years ago. I still enjoyed reading the book and seeing how well the pieces were all woven together.
There is a small plot hole in that the first murder had to be planned out before hand, yet executed with perfect luck and timing otherwise the murderer would have easily been exposed. You don't realize that unless reflect back on the book after you've finished reading. So, I'll forgiver Christie.
