After the Funeral (A Hercule Poirot Mystery) by Agatha Christie, 2/5

This book is fun, but not substantial, being short and populated with two-dimensional characters.  The twist at the end was entertaining, but I did not feel that it was very skillfully supported by the preceding plot development.  The whole thing gave me the impression that Agatha Christie had, by this time in her career, settled into a trustworthy and unique, if somewhat mundane and formulaic, writing style.  I would be interested to read some of her earlier works.
