Query: A conclusion based on speculation, not fact.

The mystery at Rennes-le-Chateau has facinated me ever since I read The Holy Blood and the Holy Grail. I was hoping that Tomb of God would expand on the mystery and perhaps answer some of the questions that I had. It is unfortunate my money was wasted. The geometry lesson left me baffled, especially the conclusion that was drawn from it. Speculation should never lead to conclusion. Unfortunatly the authors have ignored this basic tenet and left this question hanging; if you have the proof, why don't you go and get it? Without the physical evidence, the "2000 year old mystery" has no solution. This book will collect dust on my shelf as it is not worth re-reading.
