How do the final events of To Kill a Mockingbird bring the two stories of Tom Robinson's trial and the mystery of Boo Radley together and exemplify the title of the book?
Earlier in the book, Calpurnia tells Jem and Scout that to kill a mockingbird is a terrible thing; to kill something that is so beautiful and never harmed anyone. Boo and Tom are both like the mockingbird in that they did not cause anyone any harm, and yet both are harassed and accused of things that they did not do.
