Chapter 29 of To Kill a Mockingbird is important for two reasons: Scout delivers a blow-by-blow account of the attack (by Bob Ewell, although she was not immediately aware of it), and Boo Radley finally makes his appearance. Sheriff Heck Tate quizzes Scout on what happened during the attack, and she tells him the whole story--from the footsteps that "walked when we walked and stopped when we stopped" to the man who was "staggerin' around and pantin' and--coughing fit to die." When Sheriff Tate asked Scout who the man was, Scout responded:

    "Why, there he is, Mr. Tate, he can tell you his name."
    As I said it, I half pointed to the man in the corner...

It was Boo Radley.

    "Hey, Boo," I said.

The chapter also serves as the immediate descending action that follows the climactic attack and death of Bob Ewell.
