LAPD Detective Renée Ballard tracks a terrifying serial rapist whose trail has gone cold with the help of the newest volunteer to the Open-Unsolved Unit: Patrol Officer Maddie Bosch, Harrys daughter. Renée Ballard and the LAPDs Open-Unsolved Unit get a hot shot DNA connection between a recently arrested man and a serial rapist and murderer who went quiet twenty years ago. The arrested man is only twenty-three, so the genetic link must be familial. It is his father who was the Pillowcase Rapist, responsible for a five-year reign of terror in the city of angels. But when Ballard and her team move in on their suspect, they encounter a baffling web of secrets and legal hurdles. Meanwhile, Ballards badge, gun, and ID are stolen - a theft she cant report without giving her enemies in the department the ammunition they need to end her career as a detective.
