A serial killer stalks women in rural Ohio. He is deranged but brilliant, known only by the grotesque nickname the media has given him - The Doll Parts Killer. The name is apt. He dismembers his victims and leaves them in garbage bags in public places. A residential neighborhood. Next to a roller rink. Behind a Burger King. The investigation is a disaster. No physical evidence. Unreliable witnesses. To make matters worse, the FBI has lost contact with the star profiler working the case.

Two days. Fourteen dead. The next victim could be you. The first bullet punches through the windshield of an SUV. A head shot. The driver's death is instantaneous. And it's only the beginning. A sniper along I-20 kills eight and causes a 36 car pileup. Brutal. Efficient. The next morning, the same individual stalks through a grocery store parking lot with a handgun. He takes out six innocent shoppers along with the store's front window before fleeing without a trace. 

For more than twenty-five years, Philadelphia homicide detective Bree Taggert has tucked away the nightmarish childhood memories of her parents’ murder-suicide…. Until her younger sister, Erin, is killed in a crime that echoes that tragic night: innocent witnesses and a stormy marriage that ended in gunfire. There’s just one chilling difference. Erin’s husband, Justin, has vanished.

San Francisco medical examiner Annabelle Schwartzman has spent eight years looking over her shoulder. Stalked by her vengeful ex-husband, Spencer, she’s always known they’d meet again. Has her nightmare come true? Abducted, blindfolded, yoked, and tethered, she’s being held prisoner in an isolated cabin in Idaho. But it’s the unknown that terrifies Annabelle now. Because the man’s voice in the dark, though eerily familiar, is not Spencer’s.

With her vindictive ex-husband out of prison, San Francisco medical examiner Annabelle Schwartzman is trying harder than ever to move on with her life - by focusing on her job to speak for the victims who can’t. Summoned to a homicide in Golden Gate Park, she realizes that she’d seen the victim just hours before, alive and well in a parked Jeep with a small boy. Now, the woman has been stabbed to death and stripped of her burka, and the child is nowhere to be found. Then an African American student is found dead, bearing knife wounds identical to those of the woman in the park.
