What is the title of C.S. Lewis’s 1942 book featuring correspondence from a senior demon?

C.S. Lewis’s 1942 book featuring correspondence from a senior demon is The Screwtape Letters. The book is presented as a series of letters from Screwtape, an experienced tempter, to his inexperienced nephew Wormwood.

Screwtape’s advice describes ways to distract a human patient from faith, moral attention, and relationship with God. Lewis uses the demonic viewpoint satirically: the reader is expected to recognize the distortions and failures in the advice rather than accept it as a guide to evil.

The book first appeared in the British weekly The Guardian in 1941, with the collected volume following in 1942. Lewis dedicated it to his friend J.R.R. Tolkien, though their friendship later became strained over the work’s satirical method.

Readers sometimes confuse this title with The Great Divorce, another Lewis book about sin, choice, and the afterlife. The distinctive clue here is the fictional correspondence between a senior and junior demon.
