“One of the great mysteries of the Catholic Church, The Shroud of Turin, has inspired one of the great writers of our time to create this masterful thriller. Two brothers -- Alex, a Greek Catholic priest, and Simon, a Roman Catholic priest -- are drawn into the intrigue surrounding the Shroud and the origins of the Church following the murder of their friend Ugo, an eccentric curator obsessed with the Shroud who was preparing a major exhibit in the Vatican Gallery. Alex and Simon are dedicated brothers and priests, yet as different in temperament and faith as they are similar in conviction and loyalty. Caldwell unveils much about the world behind the Vatican walls, even as the intricate plot builds to a climax. A spectacular achievement!”
