Live by the code. Die by the code.

Fresh off six months of work-related medical leave and still reeling from a divorce, Providence Police Detective Sergeant Nathan Press receives a cryptic letter from Riley Talbert, a prominent attorney friend, imploring that they meet. Included in Talbert's message is an ominous warning: Tell no one.

When Talbert fails to show for the meeting and instead washes up dead on a riverbank, Press and his squad of crack detectives are thrust headlong into a murder case that is far bigger than anything they could have ever imagined.

Determined to untangle the knotted clues and solve his friend's murder, Press unearths the terrible secret at the core of the investigation-a secret that some people will do anything to keep hidden. But if Press is going to expose their evil designs to the light of day and bring Talbert's killers to justice before more people die, he'll have to risk more than just his badge. He will have to risk everything, including his life.
