A Billy Harney Thriller

In The Coldest Case: A Black Book Audio Drama, homicide detective Billy Harney sends his new partner, Kate, deep undercover in a notorious Chicago drug ring. When several members of the ring soon turn up dead, Billy abruptly pulls Kate out, blowing her cover. Kate’s informant inside the gang quickly disappears. As does the ring’s black book.... When Billy can’t find the informant, he wonders if Kate is secretly harboring her, since the two grew close during Kate's weeks undercover.

Someone is committing random murders across Chicago—and making sure detectives Billy Harney (Aaron Paul) and Patti Harney (Krysten Ritter) are first on the crime scene. What connects the victims, and why is the killer leaving clues behind with each body? Billy and Patti are scrambling to stop the next killing when their father, Chief of Detectives Dan Harney (Beau Bridges), is kidnapped. But in their race to track him down, they uncover pieces of his past that simply can’t be true. Could their own flesh and blood be covering up a dark secret?

Billy Harney was born to be a cop. The son of Chicago's chief of detectives, whose twin sister is also on the force, Billy plays it by the book. Alongside Detective Kate Fenton, Billy's tempestuous, adrenaline-junkie partner, there's nothing he wouldn't sacrifice for his job. Enter Amy Lentini, a hard-charging assistant state's attorney hell-bent on making a name for herself - who suspects Billy isn't the cop he claims to be. They're about to be linked by more than their careers.

​For Detective Billy Harney, getting shot in the head, stalked by a state’s attorney, and accused of murder by his fellow cops is a normal week on the job. So when a drive-by shooting on the Chicago's west side turns political, he leads the way to a quick solve. But Harney's instincts - his father was once chief of detectives and his twin sister, Patti, is also on the force - run deep. As a population hungry for justice threatens to riot, he realizes that the three known victims are hardly the only casualties.

As Chicago PD’s special-ops leader, Detective Billy Harney knows well that money is not the only valuable currency. The filthy rich man he’s investigating is down to his last twenty million. He’s also being held in jail. For now. Billy’s unit is called in when an escape plan results in officers down and inmates vanished.
