What is the title of C.S. Lewis’s 1942 epistolary satire about temptation?

C.S. Lewis’s 1942 epistolary satire about temptation is The Screwtape Letters.

The book is presented as a series of letters from Screwtape, an experienced demon, to his inexperienced nephew Wormwood. Screwtape offers advice about tempting a human patient, allowing Lewis to discuss moral weakness and spiritual distraction from an inverted viewpoint.

The letters first appeared in book form in 1942. Lewis used irony rather than a straightforward sermon, so the demonic narrator’s advice is meant to expose the habits and excuses that can undermine a person’s moral and spiritual life.

Readers sometimes confuse this book with The Great Divorce, another imaginative work about spiritual choices. The Great Divorce is a visionary narrative involving a journey from a grey town, while The Screwtape Letters uses correspondence between demons as its central structure.
