Miss Marple's evolution.
I was wondering if anybody had any comments to make on how later Miss Marple stories from the 1950's and 1960's, differ from earlier stories such as those within The Thirteen Problems. What would you say are the differences between them. Does the structure or style which Agatha Christie uses change? Are the characters better explained or developed in the newer stories? I am doing some research on this topic for University and would love peoples opinions. Any comments would be great help.
