In this book, Dan Green presents his thoughts on the possibility of the murder of Mary Magdelene and her body being laid to rest in the grounds of Lincoln Cathedral. Working through codes that he has found throughout the cathedral and its environs, whether by sacred geometry or hidden messages in memorial plaques, he gives a well-thought out and intricately explained hypothesis which leads the reader to think hard about the coincidences that he has brought to light. He weaves in connections with the infamous Rennes-le-Chateau to add weight to his argument. Is there any truth in his suggestion that Mary Magdelene was, in fact, the wife of Jesus and was pregnant with his child at the time of her murder? For researchers and intrepids alike, the solution to the mystery that is Rennes-le-Chateau would be the discovery of a clear and unamibiguous location whereupon resides the lost 'treasure' once guarded by the warrior monks of the Knights Templar, a historical secret involving the biblical Jesus and his alleged wife, the mysterious figure that is Mary Magdalene. For centuries a fruitless search for the ever changing allegory of this 'Holy Grail' has taken place in France despite many considering that it has always remained hidden in England. Where the 'psychic' appears to meet with the psychological and mystical submerged secrets of the Collective Unconscious, amidst a series of astonishing synchronicities, a hint of tunnels and a labyrinth of cracked codes in both France and England, a 'Lincoln Cathedral Code' discovered within the architecture and sacred geometry of this ancient Gothic Cathedral with its nearby puzzling place name 'Jerusalem' and once nearby thriving Jewish community, gives the most convincing evidence yet for a concealed revelation amidst a battleground of Light and Dark, and an additional and shocking twist to challenge contemporary theories of a holy bloodline, suggesting that not only was a pregnant Mary Magdalene murdered but that the very identity of the Jesus figure may now also be brought in to question...
