This year is the eightieth anniversary of the publication of The Screwtape Letters by C.S. Lewis. Brenton Dickieson has written an excellent history of the work (complete with interesting ephemera) at A Pilgrim in Narnia. The book was wildly successful at the time. It played a crucial role in the establishment of Lewis as a public figure. Dickieson observes that in the famous issue of Time depicting Lewis on the cover, “he is described as a ‘celebrity’ whose platform was built upon The Screwtape Letters.”
