Rome. A city where rules are compromised. And compromise rules. It's one of the hottest days of the year. Chief Inspector Blume is enjoying a rare solitary lunch in a tranquil corner of Trastevere when an unwelcome phone call intrudes with news of a brutal killing a few streets away. Arturo Clemente is no ordinary victim. His widow is an elected member of the Senate, and Blume arrives at the scene to find enquiries well underway, the case itself apparently clear-cut, a prime suspect quickly identified. Blume must fight to regain control of the investigation, but well acquainted with the city's underworld, he knows from bitter experience that in Rome even a murder enquiry must bow to the rules of politics. But when worrying shortcuts sanctioned by one of his superiors are uncovered, it seems events are being manipulated from on high. The complex and uncomfortable truth Blume will unravel will shock even him, and his struggle for justice may yet cost more innocent lives...
