Myth to Reality in The Screwtape Letters

The way that Lewis' novel  The Screwtape Letters is set up demonstrates his mastery of using myth to connect readers to what is real. Nobody knows whether it is true that demons write letters to each other or have demon apprenticeships to learn from one another about how to be the best demon he can be. However, the way that Lewis sets up the novel with an excited nephew writing letters full of questions about his line of work to his uncle Screwtape is a use of myth to explain the real. Lewis uses Screwtape's responses to Wormwood to demonstrate how demonic activity and oppression works in a man's everyday life, through a means of one demon communicating with another in a casual way.
