This book was recommended to me by a friend that recently left Freemasonry. It is interesting and explains a lot of things about Masonry that 'profanes' wouldn't know anything about. My friend told me that 99% of the book is accurate. The 1% that he couldn't vouch for was because different Lodges have different practices. The big downfall of The Deadly Deception is that it is poorly written. It seemed to me that the arthor felt readers needed a Dick and Jane style of writing to understand Masonry. It was rather insulting at times.
