Oh, yes, definitely! It's just that I've apparently slotted Christie into my head as "breezy fun character work," and not as much "interesting structural mysteries," and then my brain got surprised and recalcitrant when given the latter more than the former, and I am now surprised that Christie is slotted into my head that way because she's after all known for being a mystery writer! But I guess not surprising, because she really does also do breezy fun character work quite well :)
