Ex-cop Bierce has been in prison for over twenty years following his conviction for the murders of his wife and son. He has no memory of the tragedy and has never been able to say with certainty that he didn't do it - except he cannot imagine why on earth he would have killed his beloved family. Unexpectedly released moments before his execution, he teams up with the beautiful, feisty, half-Chinese Alice Loong, who is seeking answers to her own troubled past and the death of her mother on that same day in 1983.
In a hidden studio in an area of Rome, where the Vatican liked to keep an eye on the city's prostitutes, an art expert from the Louvre is found dead in front of one of the most beautiful paintings that Nic Costa has ever seen - an unknown Caravaggio masterpiece. But before long, tragedy will strike Nic far closer to home. The main suspect's identity is known, but he remains untouchable protected in his grand palazzo by a fleet of lawyers and a sinister cult known as the Ekstasists.
