These letters from some important executive Down Below, to one of the junior devils here on earth, whose job is to corrupt mortals, are witty and written in a breezy style seldom found in religious literature. The author quotes Luther, who said: "The best way to drive out the devil, if he will not yield to texts of Scripture, is to jeer and flout him, for he cannot bear scorn." This the author does most successfully, for by presenting some of our modern and not-so-modern beliefs as emanating from the devil's headquarters, he succeeds in making his reader feel like an ass for ever having believed in such ideas. This kind of presentation gives the author a tremendous advantage over the reader, however, for the more timid reader may feel a sense of guilt after putting down this book. It is a clever book, and for the clever reader, rather than the too-earnest soul.
