What is the title of C.S. Lewis’s 1942 epistolary novel written from a demon’s viewpoint?

The Screwtape Letters is C.S. Lewis’s 1942 epistolary novel written from a demon’s viewpoint. It consists of advice from the senior demon Screwtape to his inexperienced nephew, Wormwood.

The letters discuss temptation, distraction, pride, resentment, and everyday moral choices. Lewis creates an ironic perspective: the demons describe their work as serving “the Enemy,” meaning God, while readers understand that the demonic vocabulary reverses the moral order. The book’s satire depends on this contrast.

The work began as a series of letters and was published in book form during the Second World War. Its format makes it different from a conventional narrative, and the correspondence does not present a continuous adventure plot. It remains one of Lewis’s most widely read Christian works, alongside Mere Christianity and The Problem of Pain.
