Is the Vatican suppressing an outrageous invention? Are the remnants of a device that could turn our history upside down stored in a Swiss vault? Until his death, the Italian Benedictine Father Emilio Ernetti insisted that he had constructed a time machine that made it possible to look into the past. He was summoned multiple times before the highest church dignitaries to report in secret meetings about the fate of Jesus. With detective-like zeal, the French Father François Brune followed the trail of his friend to uncover more about the mysterious invention. His search led him all the way to the office of the former Italian Prime Minister.
