Foreshadowing is the use of hints or clues to suggest what will happen later in literature. These hints may appear in dialogue or in narration. Foreshadowing frequently serves two purposes. It builds suspense by raising questions that encourage the reader to go on and find out more about the event that is being foreshadowed. Foreshadowing is also a way of making a narrative more believable by partially preparing the reader for events which are to follow.
The Necklace by Guy de Maupassant and The Story of an Hour by Kate Chopin are celebrated as two of the best examples of the surprise endings. In The Necklace we know that at some point wants and reality will somehow crash into each other. With this in mind, it is possible to read "The Necklace" as a sort of mystery story without the traditional trappings of detectives, criminals, and crimes. The mystery here regards what will happen to Madame Loisel. From the outset it is her wants-a want of prestige, of station, of wealth, of material objects- that gives the narrative its tension and suspense. Madame Loisel is defined by what she lacks and what she is not, rather than by what she has and is. She is not a well-rounded character, but Maupassant did not intend for her to be one.
