A new book by the author of The Problem of Pain, one of the most widely discussed works of recent years.

What is the enemy thinking? The question is often asked about Hitler; less often, even in Christian circles, about "our ghostly foe". These letters, written by an elderly devil to instruct his junior in the art of temptation, may suggest an answer. The resulting picture of human nature as seen from Hell's front line may appear an amusing novelty in satire to those who do not know the classics of Christian morality; the believer, possibly smiling less, may gather some practical hints about strategy.
