In a deserted artist's studio in the heart of Rome, detectives stumble upon a scene of shocking brutality: two bodies, freshly killed. Looming over them is a painting that bears all the hallmarks of a Caravaggio: a brilliantly colored canvas depicting a violent tableau of beauty and depravity. This grisly discovery sends Detective Nic Costa on a desperate chase through the streets of his city--a chase that will have devastating consequences.--From publisher description
