I really didn't read many of Agatha Christie's books until this series began with Geraldine McEwan, who I really liked. Now we have Julia McKenzie who is a very different, but also totally likable Miss Marple. Both actresses put their different imprint on the role. I've enjoyed most of these Miss Marple movies, with a few exceptions of course. This season seems to be deeper into the human psyche than others. I care about the characters a bit more and "Carrie Louise" is worthy of Miss Marple's protection. That takes some doing since she kindly takes care of some criminal-minded youths. Who done-it? I Loved Miss Marple figure it out. Some people mentioned, and I agree that the addition of Joan Collins doesn't help the cast at all. But her appearances are sparse, I'm happy to say. A friend told me that Christie wrote more Poirot stories than Miss Marple, so it's more limited. I'll be sad to see the series end.
