What is the title of C.S. Lewis’s 1942 epistolary satire narrated by a senior demon?

C.S. Lewis’s 1942 epistolary satire narrated by a senior demon is The Screwtape Letters.

The book is presented as a series of letters from Screwtape, an experienced demon, to his inexperienced nephew Wormwood. Screwtape gives advice about tempting a human being, allowing Lewis to explore moral weakness, distraction, pride, and spiritual self-deception from an intentionally inverted viewpoint.

The work first appeared in 1941 in the Anglican newspaper The Guardian and was published as a book in 1942. Its format makes it different from a conventional novel: readers receive the demon’s correspondence rather than a straightforward account narrated by Lewis.

The title is sometimes confused with Lewis’s other apologetic works, particularly The Problem of Pain and Mere Christianity. The Screwtape Letters is distinctive for combining Christian ideas with satire, irony, and the fictional voice of a senior tempter.
