Sheriff Tate arrives and discovers that Bob Ewell has died during the fight. The sheriff argues with Atticus about the prudence and ethics of charging Jem (whom Atticus believes to be responsible) or Boo (whom Tate believes to be responsible). Atticus eventually accepts the sheriff's story that Ewell simply fell on his own knife. Boo asks Scout to walk him home, and after she says goodbye to him at his front door he disappears again. While standing on the Radley porch, Scout imagines life from Boo's perspective, and regrets that they had never repaid him for the gifts he had given them.
