Gone Girl, the 3rd of Gillian Flynn’s works (each “darker” than the previous, according to the reviews I’ve skimmed through), is the story of Nick and Amy Dunne, a painfully beautiful and charming couple who had a romcom-ishly perfect courtship and marriage only to realise that they are, basically, two psychos. Seriously. There is no other word for it! Now I’m not going to go into the plot because I’m pretty sure half the world have seen this movie and been adequately scarred for life. At least I was.
