Ending of To Kill a Mockingbird

The ending of the novel surprised me, but fitted well with the starting. If I was the author, I would not have ended the story differently. Why? Firstly, one incident resolved every unresolved item in the story. Secondly, the ending fitted very well with the starting, which was why the story should be read from end to end then started again. And thirdly, it was brilliant twist, and I usually try to add twists to my stories, and thus if I had written the ending, it would be the same as Harper Lee's.
