While this one is something of a fan favorite, we were surprised by the simplicity of the central mystery upon a reread, given all the Christie puzzles we've solved thus far.... Add to that a number of characters who are never really suspects, plus a few absurd side-plots that don't quite hang onto the main action as they should, and we come out a bit more critically on this one than we expected, despite retaining a healthy affection for some of this Poirot novel's better elements.
