Matt Baker and Anita Rani explore the beauty of the Malvern Hills and discover how this area inspired writers such as JRR Tolkien and CS Lewis and composer Edward Elgar. Anita visits Malvern College, where Lewis studied and was visited by his friend Tolkien, and up on the hills she meets a group of young writers hoping to follow in the great masters' footsteps. She also steps into Narnia as she meets the world's only female gas light engineer, who repairs and maintains the famous lights that influenced CS Lewis. Matt is on the musical trail of Elgar and meets cellist Sheku Kanneh-Mason for a special Countryfile recital. Adam Henson welcomes a very festive new arrival to his farm, and Tom Heap investigates the toxic risks being served up in our winter game.
