This book does have curious information and even some interesting observations but egads! The book is meandering, ill-focused, disdainful of others 'methods' and darn near unreadable!A Priest - one could almost imagine Lionel's veins popping in righteous indignation with his smirking dismissive of the 'the Holy Blood and the Holy Grail' researchers while He and his wife sew together a hodge-podge of theories, beliefs and plain flights of fancy into an incoherent pastiche that puts a whole new slant on 'faith-based' reasoning.Its clear that the authors did a lot of on-site research, they may actually have a lot of information but getting it out of this book is like shifting through the sands of the Sahara to get a few nuggets.
