They know exactly when he’ll strike… They just have to find him first. In all their years working for the Baywood police department, detectives A.L. McKittridge and Rena Morgan have never seen anything like it. Four women dead in forty days, each killed ten days apart. With nothing connecting the victims and very little evidence, the clock is already counting down to when the next body drops. A.L. and Rena will have to act fast if they’re going to find the killer’s next victim before he does. But identifying the killer’s next likely target is only half the battle. With pressure pushing in from all sides, a promising breakthrough leads the detectives to Tess Lyons, a woman whose past trauma has left her too damaged to appreciate the danger she’s in. Unwilling to let another woman die, A.L. and Rena will put everything on the line to keep Tess safe and end the killer’s deadly spree once and for all—before time runs out again.
