La espada del diablo

William of Yorkshire is a Templar knight with an extraordinary capacity for deduction; a gift that has led him to solve mysterious events throughout his career in the Order, both in Europe and in the Holy Land. A virtue that opened the doors of an enigmatic brotherhood within the Temple that guards its true treasure. Jacques de Autier has been educated within the Cathar creed and, through his gaze, the reader will witness the fall of Montségur and will have access to the secrets that were hidden in the impregnable Occitan fortress. The lives of both will be intertwined when William tries to solve the murders of several abbots of the seven monasteries built on the pit that the sword of the archangel Saint Michael struck the earth during his confrontation against the devil. Seven temples arranged in a rigorous straight line over thousands of kilometers from Ireland to the Holy Land. Seven sacred enclaves that, of course, exist. God and the Devil vie for the soul of each man. But not even a Templar accustomed to living with death could suspect that the outcome of that game would depend on him. The quest for the Ark of the Covenant or the Holy Grail pales before the challenge that William of Yorkshire has to face. That adventure is not only the most terrible of his life; It is also the most important for all of us, due to its importance for Humanity. The Templar secrets, the Cathar treasure, the devil's sword ... The game has started, do you dare to participate?
