Charles Williams was a friend of J.R.R. Tolkien, C.S. Lewis, T.S. Eliot, Dorothy Sayers, and other influential writers of the early 20th century. He wrote seven startling metaphysical thrillers: bizarre, engaging, wild novels in which the supernatural invades ordinary life. In this course, we'll talk about War in Heaven, in which a saintly archdeacon, a poetic duke, and a publisher's clerk race to save the Holy Grail from the three satanists who want to use it to destroy the world.
