Sold as a thriller as good as Da Vinci Code, I was weary of it. I hate the Da Vinci Code but I had come across reviews that were negative because it wasn't anything like the Da Vinci Code except for the Vatican and there's a painter involved in it aspect. The plot has a lot to offer. A fallen cardinal involved in very shady financial transactions, a serial killer with an obsession with martyrs, a young academic with a sulfuric past and two police detectives a burnout older man and a younger cop with an obsession with Caravaggio. The plot moves slowly and has some surprising little twists some you see coming a mile away others that hit you from the sideline. It's not a Da Vinci clone and that's a very good thing. It's not an exceptional thriller, just an okay one set in Rome at the height of a heatwave, where the people running the show are in an another country right in the heart of the city. First in a series of novel featuring Nic Costa the young cop. I'll check out the second one.
