How this guy continues to get published is beyond me. He never presents a fact...he'll start out with an assumption, discuss it, and then later on, build a new assumption on the previous assumption, but now present it as if it were fact!
I've been a 32nd Degree Mason of the Scottish Rite for over 10 years now...and Knight's books have always been good for one thing and one thing only: a laugh at Knight's own ignorance. I read The Hiram Key with an open mind and an attempt to see where he was coming from. The only value that book had was for entertainment purposes, and for spurring of some interesting debate amongst Lodge members.
Refer back to one of his other books where he discusses Jacques De Molay as the source of the Shroud of Turin. While an interesting theory, he never once provides compelling proof of, well, anything.
A wonderful storyteller, nothing more. If you're looking for FACTUAL books about Masonry, do not look to Christopher Knight for the truth.
