Sometimes, the best way to begin a story is to announce that you’re about to tell a story. English storytellers have been doing this since at least the first recorded use of the phrase “Once upon a time” in the 14th century. Mark Twain’s The Adventures of Huckleberry Finn starts off this way, as does J.D. Salinger’s The Catcher in the Rye. After all, a brilliant opening can be as straightforward as: “You are about to begin reading Italo Calvino’s new novel, If on a Winter’s Night a Traveler …” (which really does start exactly that way).
