"Bizarre and cryptic messages found on a pair of corpses in Mobile, Alabama, launch junior police detective Carson Ryder and veteran cop Harry Nautilus into a desperate search for a mysterious killer. With the body count rising, Ryder descends into his family's terrifying past by seeking advice from his brother, a violent, taunting psychopath convicted of similarly heinous crimes. Ryder soon confronts not only his past fears and nightmares, but also the knowledge that someone he knows is the next target. And time is running out."--Jacket.
