Chapter 28 describes the Halloween festivities in Maycomb. A pageant has been arranged to keep the town’s children out of trouble. Scout is dressed as a giant ham. Jem escorts her to the play and home, and they are attacked by Bob Ewell. Boo Radley intervenes, and kills Ewell. He brings the children home, and Jem has a broken arm.
Mr. Tate found his neck and rubbed it. "Bob Ewell's lyin' on the ground under that tree down yonder with a kitchen knife stuck up under his ribs. He's dead, Mr. Finch." (ch 28)
Not long after the children arrive, Heck Tate, the sheriff, is called. In the next chapters, they decide what to do. Atticus thinks that Jem killed Bob Ewell. They realize it is Boo. Heck Tate suggests that they not tell anyone who the real killer is, because Boo Radley would not like the attention. Scout begins to understand Boo Radley better, and appreciate him more as a friend.
