Classic Black Magic from Dennis Wheatley: The Devil Rides Out, To the Devil a Daughter, Gateway to Hell
"I desire to state that I, personally, have never assisted at, or participated in, any ceremony connected with Magic - Black or White....Should any of my readers incline to a serious study of the subject, and thus come into contact with a man or woman of Power, I feel that it is only right to urge them, most strongly, to refrain from being drawn into the practice of the Secret Art in any way. My own observations have led me to an absolute conviction that to do so would bring them into dangers of a very real and concrete nature." (DENNIS WHEATLEY)"
