A conversation between Flora Ackroyd and James Sheppard in Agatha Christie's The Murder of Roger Ackroyd: "That pen that George Eliot wrote The Mill on the Floss with—that sort of thing—well, it's only just a pen after all. If you're really keen on George Eliot, why not get The Mill on the Floss in a cheap edition and read it? ... I suppose you never read such old out-of-date stuff, Miss Flora? ... You're wrong, Dr Sheppard. I love The Mill on the Floss ."
In Robert A. Heinlein's 1952 novel The Rolling Stones, Capt. Roger Stone asks his twin sons, Castor and Pollux, "Don't you want to study the world's great literature?" and Pollux replies that "we don't want to read The Mill on the Floss."
