Kill Switch

Dr. Claire Waters understands what motivates violent criminals and tries to prevent further offenses. Haunted by a childhood brush with a vicious crime that was never solved—the abduction of her best friend—she must confront her fears when she takes on her first serial killer case. She meets with Todd Quimby in the bowels of Rikers Island prison and sets out to crack his tough exterior, but she overlooks his violent nature and recommends his release. Within twenty-four hours the body of a woman is found in Times Square, bearing all the hallmarks of a Quimby victim. The killer taunts her, her supervisors doubt her, the cops resent her, and her boyfriend questions her loyalty. Determined and daring, Claire agrees to be a decoy. Risking everything, she uncovers a devious medical conspiracy that threatens to disrupt the international balance of power.
