What is the name of C.S. Lewis’s Christian allegory featuring the demon Screwtape?

C.S. Lewis’s Christian allegory featuring the demon Screwtape is The Screwtape Letters. The book is presented as a series of letters from Screwtape, an experienced demon, to his inexperienced nephew Wormwood.

Screwtape advises Wormwood on tempting a human subject away from Christian belief and moral discipline. Lewis reverses the usual viewpoint: readers hear the demons’ strategic language while infering the spiritual lessons behind it.

The work first appeared in book form in 1942. It was written during the Second World War, when Lewis was already becoming known for Christian broadcasts and essays. The unusual format made the book both memorable and accessible.

Despite its comic tone, the book is not a handbook of demonic doctrine. Its purpose is moral and theological satire, exposing habits such as distraction, pride, resentment, and self-deception.
