Really nice book in which Napoleon Hill interviews the Devil and asks him why the Devil acts in certain ways. The stories the Devil tells then reinforces principles from other books by Napoleon Hill about positivity and the law of attraction. Contrasts the dangers of negative emotions such as envy, jealousy, dishonesty and the pitfalls that addiction can cause.
If we can act true to good values life would be simpler. In the long term acting without integrity will catch you! This book was
