Dr. Harry Lee Poe argues that C.S. Lewis fell "in love with a story," and that he kept telling this "there and back again" story "over and over again." Dr. Poe is the Charles Colson Professor of Faith and Culture at Union University and an indirect descendant of Edgar Allan Poe. In this week's episode, he sits down with Crystal and David to discuss his latest project as well as his thesis about Lewis's one great idea.
