Some thirty years ago, Henry Lincoln first learnt about a strange mystery set in the tiny French village of Rennes-Le-Chateau where a secretive and flamboyant priest, Berenger Sauniere, became fabulously rich after finding some ancient documents in his church. Thus became Henry Lincolns trail to discover the truth behind his unexplained wealth. Three BBC television documentaries followed, culminating in the publication of the worldwide bestseller THE HOLY BLOOD AND THE HOLY GRAIL in which a hypothesis was put forward that perhaps the priest had stumbled across a fact known only to the initiates of a secret society the Priory of Sion. Here was a secret that seemed to turn history on its head. Is it possible that Jesus was married? Did he father a blood line which still survives today. The mystery also seemed to involve the Knight Templars and their fabled treasure. Clue after amazing clue was uncovered by the author and, in KEY TO THE SACRED PATTERN, he sets down for the first time the dramatic and entertaining story of his search. Henry Lincoln presents the unarguable facts behind this strange and gripping mystery far older than Christ and stretching back into an undreamt past.
