"A Warning to the Curious" is a ghost story by British writer M. R. James, included in his book A Warning to the Curious and Other Ghost Stories first published in 1925. The tale tells the story of Paxton, an antiquarian and archaeologist who holidays in "Seaburgh" (a disguised version of Aldeburgh, Suffolk) and inadvertently stumbles across one of the three lost crowns of Anglia, which legendarily protect the country from invasion. Upon digging the crown up, Paxton is stalked by its supernatural guardian. Written a few years after the end of the First World War, "A Warning to the Curious" ranks as one of M. R. James's bleakest stories.
