The Order
Alex Bernier, a priest of the ancient Carolingian order, is sent to Rome to investigate the mysterious death of their leader. The corpse has a strange mark on the chest—possibly the imprint of a "Sin Eater," a criminal who offered forgiveness outside the church. With the help of his partner, Father Thomas, and an artist he once exorcised, Alex becomes entangled in a mystery that places him at the center. Who is the real Sin Eater?
