What does Miss Maudie tell Scout about Boo? How does this compare with what Scout already believes?

Miss. Maudie tells Scout the truth about Boo Radley. She explains how Boo got into trouble with some teenagers, and, in a plea bargain with the judge, was locked up in his father's house for pretty much eternity. She explains how Boo had stabbed his father in the leg with scissors. This differs from Scout's understanding that Boo is a freak who eats squirrels and stalks children. Miss.
