C.S. Lewis named the demon narrator of The Screwtape Letters Screwtape.
The 1942 book is presented as a series of letters from Screwtape, a senior demon, to his inexperienced nephew Wormwood. Screwtape gives advice about tempting a human referred to only as “the Patient.” Lewis uses this fictional correspondence to reverse the usual perspective and satirize spiritual complacency, self-deception, and ordinary bad habits.
The letters originally appeared in the Anglican newspaper The Guardian, beginning in May 1941. The series was later published as a book by Geoffrey Bles in 1942.
Wormwood is a frequent source of confusion because he is the recipient of the letters, not their author. The book’s title names Screwtape, whose voice frames the entire work.
