The writer builds a story within a story.

A frame story is a type of narrative that is set up in order to provide a background for a more important story, or for a series of stories. The Canterbury Tales, for example, is a frame story, as it is designed to contain the smaller stories that the pilgrims tell throughout their journey. Other famous examples of frame stories are The One Thousand and One Nights and The Decameron.
