Balzano and Byrne

A devious serial killer lays siege to the city of Philadelphia, brutally sacrificing pretty young Catholic girls on the altar of insanity. As the body count rises, an exceptional investigating partnership struggles to stop him. Detective Jessica Balzano, Philly's Homicide Unit's newest rookie, is teamed up with veteran cop Kevin Byrne, respected for his solve rate and known for his unorthodox methods.

Philadelphia police detectives Kevin Byrne and Jessica Balzano are working a new beat: the Special Investigations Unit, aka the cold case squad. Ironic, given that it's the height of a blazing hot August. But even these hardened homicide veterans are chilled to the bone as a dormant murder case stirs to life - leading Byrne and Balzano into the dark heart of their city, their souls, and a psyche of pure evil.

It is fall in Philadelphia and the mutilated body of a man is found in one of the poorest neighbourhoods of the city. The victim has been viciously tortured to death. It's the work of a sadistic mind in free fall.When homicide detectives Kevin Byrne and Jessica Balzano investigate, they soon realise that their crime scene is linked to the past. Eight years ago, another body was found in the same place, in the same position, killed in the same manner.

Nothing will ever be the same again.... In the heart of Philadelphia's badlands, homicide detectives Byrne and Balzano are called out to a particularly chilling crime scene. Once the pillar of the neighbourhood, an abandoned church has become a killing room. At first it looks like a random act of violence. But then a second body is found, and a third. Each crime scene more disturbing than the last, each murder more brutal.

Destroyed by fire years ago, the infamous Philadelphia State Hospital was known as a warehouse for the criminally insane. But one man never left. By night Luther walks Philadelphia's backstreets, drawing to him the mad, the corrupt, the fallen. By day he roams the catacombs beneath the city, killing his prey. Detectives Kevin Byrne and Jessica Balzano are called to a bizarre murder scene: a man has been killed by a railroad spike driven into his head and left sitting on a bench in a local park.

The Farren family has been a plague upon Philadelphia's most dangerous neighbourhood, the Devil's Pocket, for generations. There, row after row of tumbledown houses hide dark secrets - none darker than Billy, the youngest Farren. Afflicted by a syndrome that means he can't recognise faces, Billy must use photographs to identify his family - and his victims. And when your life has bled away, he takes a final, gruesome picture for his wall.
