What was the title of C.S. Lewis’s 1942 Christian satire featuring a senior tempter?

The Screwtape Letters is C.S. Lewis’s 1942 Christian satire featuring a senior tempter.

The book is structured as a series of letters from Screwtape, an experienced demon, to his inexperienced nephew Wormwood. Screwtape offers advice about tempting a human patient, so the narrative presents moral and spiritual issues from the viewpoint of Hell’s bureaucracy.

Lewis wrote the work during the Second World War. It first appeared in serial form in the Anglican newspaper The Guardian and was published as a book in 1942. The unusual format allowed Lewis to discuss habits, distractions, pride, and moral choice indirectly through ironic advice.

The title can be confused with Lewis’s other apologetic works, especially The Problem of Pain and Mere Christianity. Unlike those books, The Screwtape Letters uses fictional correspondence and satire as its main literary device.
