An amazingly interesting history of evil covering everything from exorcism to pixies. Leonard R.N. Ashley succeeds in sustaining the readers interest by delivering hundreds of short punchy titbits of information, some chapters being only a couple of lines long, meaning you can pick it up and thumb through it, whenever you have a few minutes to spare. Particularly interesting, are the details of how various religions adopted their enemies gods to become their demons, and a list of the 103 angels who fell from heaven with Satan. All in all, a very well researched, thoughtprovoking book on a thoroughly interesting subject.
