This satirical epistolary work is a series of letters from Screwtape, a senior devil, to his nephew Wormwood, a junior tempter. Wormwood has been given charge of an ordinary young man in wartime England, and Screwtape offers advice on how to lead him away from faith and goodness. By seeing things from the devils' side, Lewis shows common human weaknesses such as vanity, distraction, self-deception and small cruelties. The book is witty, sharp and unsettling. It is a popular and original way of examining conscience and everyday moral choices.
