About 3/4 of the way through Agatha Christie's 'And Then There Were None' (pub c.1940), is this paragraph, describing a book, or maybe a story in some other kind of format:
She broke off, went on: "I read a story once - about two judges that came to a small American town from the Supreme Court. They administered justice - Absolute Justice. Because - they didn't come from this world at all."
I'm curious at random, whether this passage described an actual book or short story, or perhaps whether a book or short story was written subsequently on that theme.
