Arthur “Boo” Radley lives in the run-down Radley Place, and no one has seen him outside it in years. Scout recounts how, as a boy, Boo got in trouble with the law and his father imprisoned him in the house as punishment. He was not heard from until fifteen years later, when he stabbed his father with a pair of scissors. Although people suggested that Boo was crazy, old Mr. Radley refused to have his son committed to an asylum. When the old man died, Boo’s brother, Nathan, came to live in the house with Boo. Nevertheless, Boo continued to stay inside.
