I never read the book, but in the movie why did Buster bother to write down the quote from the book, "there is a justice higher than that of man, I'll be judged by him?" Then we see him with the quote on a piece of paper while going through old newspaper clippings of Annie.
shareAnne had said that to the jury when she was accused of killing those kids. She got the qoute from one of Paul's Misery novels, and when Buster saw that Anne had said that, he knew she was quoting Paul, so he decided to go to her house, thinking she may have him. Which was obviously a bad idea
shareNo, going there without backup, THAT was obviously a bad idea.
shareHe probably thought that because she was a woman,She wouldn't be a real threat. See what happens when you underestimate women.
shareWhen he reads it in the Misery novel, it rings a bell. But he’s not sure why. When he sees Annie throw her tantrum at the other driver in town, he remembers. She was hauled into court once, too! Could she have been the one who quoted Paul Sheldon?
shareI figured it was a famous case involving the town weirdo and Buster remembered Wilkes being quoted as saying something like that as she was hauled into court, that’s what made him write it down in the first place - when he read the book he recalled that phrase from somewhere, then he went to the library to confirm it.
