I did not realize how long Christie’s career was! This was published in 1969! Unfortunately it seems I like her earlier work a lot better. There was a lot of moaning and groaning from these characters about how “things aren’t like they used to be.” Eye roll. I can’t say much without spoilers, but the premise of the mystery was pretty interesting, though the twisty ending seemed so out of left field? There wasn’t as much foreshadowing (that I picked up on anyway), so I felt a bit confused at the end.
