One of the best books of Christie's long and varied career has perhaps as well one of her most heartbreaking resolutions. You almost can't wait for the victim to be done away with at the same time, you feel for their murderer. Not easy to pull off ( making the killer sympathetic) but AC does it flawlessly. This ranks right up there in her top twenty.
