In his 1972 documentary, "The Lost Treasure of Jerusalem", Henry Lincoln showed the first glimpse of the extraordinary phenomenon hidden behind the mystery of Rennes-le-Chateau -- the tiny village in the French Pyrenees -- and the sudden and unexplained wealth of its flamboyant priest, Berenger Sauniere.

It was a story that ignited the world's imagination and the book that followed, Holy Blood, Holy Grail, became an instant bestseller on both sides of the Atlantic. Now, in Key to the Sacred Pattern, he sets down the dramatic story of his thirty years of delving into one of the strangest mysteries of modern times -- and enables us to sense the slow strengthening of the solid facts out of a mass of maybe's.

Key to the Sacred Pattern takes us further into the hidden byways marked out by our ancestors and sets them upon provable and demonstrable foundations. These people were not, as we have thought, primitive and unenlightened, but far more gifted than we have ever imagined. This book lifts the veil on a mysterious and dramatic legacy.
