So who was Richard Leigh? Well back in the early 1980's he co-write this little book that the catholic church hated, and said it was heresy. If it was not for me reading this little book, I would not have made the decision I did to leave the church I was raised in. And if it was not for this book, Dan Brown would not have written such a succesful novel about some painter, since he virtually lifted a major name from this other little known book, and was taken to court for it. Dan Brown won. And of course the other little book was called Holy Blood, Holy Grail.
