As with pretty well everything Christie, this is an excellent read. My usual gripes, e.g. all 'locals and servants' speaking "There's them as says..." language is there, as is the usual Poirot expostulation that he has been "an imbecile - I have been an imbecile" about three times before he finally solves it. But - petty when compared to the easy reading enjoyment this book provides. The twists and tricks leave you thinking that first X did it, then Y, then Z, and, as usual, not spotting the real culprit until Poirot reveals who it is. The way he puts the clues together is fanciful, improbable to the poiint of impossible, but, hey, I'm getting petty again! Buy it, read it, it is excellent enjoyment.
