Which C.S. Lewis book features the demon narrator Screwtape?

The demon narrator Screwtape appears in C.S. Lewis’s The Screwtape Letters.

The book is written as a series of fictional letters from Screwtape, a senior demon, to his inexperienced nephew Wormwood. Screwtape offers advice about tempting a human patient, allowing Lewis to examine moral habits, self-deception, pride, distraction, and spiritual choice through satire.

The Screwtape Letters was first published in book form in 1942. Lewis had originally developed the material in letters broadcast by the BBC during the Second World War, and the work’s epistolary format gives it a deliberately indirect structure. The narrator is not Lewis himself; he is a fictional demon whose observations are meant to be read ironically.

The book is often grouped with Lewis’s Christian apologetics, but it differs from direct works such as Mere Christianity because it presents its ideas through imaginative inversion rather than straightforward argument.
