Laws of Depravity by Eriq La Salle

30 years. 36 priests butchered. His bloodiest masterpiece is yet to come.

Every ten years, for the past 30 years, a dozen clergymen are killed, brutally murdered in twisted scenes emulating the deaths of Jesus and his disciples. Now, "The Martyr Maker" has set his mark on New York City. The Laws of Depravity follows two NYPD detectives and an FBI agent as they race to catch a serial killer before he completes his last cycle of kills and disappears forever.

Apart from his critically-acclaimed thriller titles, La Salle is a masterful mystery/crime storyteller. He may be best known for his acting roles in productions such as ER, Coming to America, and Logan, but his background in crime fiction was finely honed as he directed and executive produced countless episodes of popular shows such as Law & Order, Law and Order SVU, Law & Order: Organized Crime, CSI: NY, and Chicago PD with Dick Wolf.
