Hell Hath No Fury is one of Richard Castle's novels. It is mentioned in Flowers For Your Grave (episode 1.1) during Castle and Kate Beckett's first interrogation. Beckett shows Castle a photo of a crime scene where a small claims lawyer was murdered and posed similar to a scene in the book. Castle notices that Beckett recognized the similarity between the crime scene and the book scene and figures out that she is a hard-core fan of his writing. He also mentions that the book has to do with "angry Wiccans out for blood."
