Claire Waters is a dedicated forensic psychiatrist with unnervingly personal insights into the criminal mind. Haunted by a disturbing childhood incident, Claire has always been drawn to those rare "untreatable" patients who seem to have no conscience or fear. But one shocking case could make or break her career-and it's waiting for her in the psychiatric wing of New York City's Rikers Island. Quimby is a deranged inmate whose boyish good looks hide a sordid history of dysfunction and abuse, and he triggers something in Claire she'd rather not face. As she tries to unlock Quimby's past, she leaves herself dangerously vulnerable. When the case propels her into the mind of another killer-a homicidal maniac who's watching her every move-it could only end in madness, or murder, or bothz Brilliantly constructed and breathtakingly suspenseful, Kill Switch is a masterful combination of murder, mystery, and modern forensics- and a stunning debut from a spectacular writing team
