I am more of a Poirot reader, just because that's the first Christie I read, and I didn't read any Miss Marple books until many years later. There are two volumes of 5 complete Christie books - one Poirot/one Marple - that have a great selection of each. The Poirot one doesn't include one of my favorites - The Man in the Brown Suit. I found Cat's Eye completely devastating. It's my favorite Margaret Atwood novel, although it's hard to say I "liked" it.
