Somewhere I read that this was rated the number 1 locked room mystery of all time, so of course, I had to read it. Many parts were riveting, but the ending was too much of an explanation/reveal. I wish more of the clues had come out during the story instead of magically at the end. Chapter 17 was BRILLIANT--basically a lecture on how to create a locked room mystery. A how-to inside a whodunit. AND THEN THERE WERE NONE remains the best IMHO.
