An enjoyable mystery

This is the second Agatha Christie novel I have read, and the first Miss Marple. I love mysteries, and this one was pretty good. I was surprised by the ending, and that’s always a good thing when it comes to mysteries. However, it was difficult to get into the story at first. There were too many characters that were not developed enough for me to have a clear picture of who they were. Obviously, a lot of characters are needed, but it’s hard to develop them all in such a short book. Finally, the evidence Miss Marple used to solve the mystery seemed a little incredible. However, I did enjoy the story.
