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 Many Dimensions, in which a magical stone engraved with the letters of the Tetragrammaton can transport people through time and space, heal illnesses, grant wealth, and otherwise transcend the laws of nature. It is up to a young secretary to offer herself as a bridge to save the world from destruction. While Many Dimensions is a kind of sequel to War in Heaven, they can be studied on their own, and students need not take that course before this one, although they are welcome to do so.
