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.

It is the steaming heart of summer in the City of Brotherly Love. Back on the force after taking a bullet during the arrest of a sadistic murderer, Detective Kevin Byrne warily returns to police headquarters. He cannot shake the memory of the Rosary Killer's innocent victims or his growing sense that the evil has not been vanquished. And when he and his partner, Detective Jessica Balzano, are called in on a bizarre case, Byrne's gravest suspicions are confirmed.

On a frigid December night, Karen sits at the edge of Philadelphia's Schuylkill River, dressed in a flowing gown, like a visitor from the distant past. A beautiful and shining young woman, she gazes up at a bone-white winter moon like a fairytale princess. At first glance, one might not even notice that she is dead, coated in a patina of ice. Homicide cops Kevin Byrne and Jessica Balzano take the lead on the case, uncovering a plethora of eerie clues, each more warped and spine-chilling than the last.

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.

Fall in Philadelphia. A man's corpse is found in one of the city's poorest neighborhoods. It's unmistakably the work of a killer. But to homicide detectives Kevin Byrne and Jessica Balzano, it feels familiar. Eight years ago another body was found in the same place, in the same position...killed in the same manner. Even the crime-scene photos are identical. That case was never closed. And now more copycat murders are happening. Someone is recreating the city's most infamous unsolved killings, victim by victim - with more clues for Byrne and Balzano to unravel.

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 neighborhood, 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. And it soon becomes horrifyingly clear that a cold, calculating, and terrifyingly precise mind is at work.

Luther Wade grew up in Cold River, a warehouse for the criminally insane. Two decades ago the hospital closed it doors forever, but Luther never left. He wanders the catacombs beneath the city, channeling the violent dreams of Eduard Kross, Europe's most prolific serial killer of the 20th century. A two-year-old girl is found wandering the streets of Philadelphia in the middle of the night by detectives Kevin Byrne and Jessica Balzano. She does not speak, but she may hold the key to solving a string of murders committed in and around Priory Park.

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.

Detectives Byrne and Balzano return to the streets of Philadelphia to put an end to a macabre succession of murdered children. A quiet Philadelphia suburb. A woman cycles past a train depot with her young daughter. There she finds a murdered girl posed on a newly painted bench. Beside her is a formal invitation to a tea dance in a week's time.

Plagued with a rare disease that prevents him from recognizing faces, Billy carries a photograph in his pocket that is his only way of identifying his next target. Killing is in Billy's bloodline as a member of Philadelphia's dangerous Farren crime family. While Billy stalks Philadelphia, Detective Kevin Byrne is assigned to a series of bizarre home-invasion cases and is joined by his former partner turned assistant district attorney, Jessica Balzano.
