I just recently came across a cheap copy of Decker's Complete Handbook on Mormonism (Harvest House, 1995) by Ed Decker (of The God Makers fame). I decided to purchase it out of morbid curiosity to see just how bad it will be. Notwithstanding, some good did come out of evil in this score, as Daniel C. Peterson wrote a very good review of this book when it came out a number of years ago now:
