On his first night with Detroit PD, Officer Walter O'Brien is called to a murder scene. A terrified twenty-year-old has bludgeoned her kidnapper with skill that shocks even O'Brien's veteran partner. The young woman is also a brilliant escape artist. Her bold flight from police custody makes the case impossible to solve--and, for Walter, even more impossible to forget. By the time Walter is promoted to detective, his fascination with the missing, gray-eyed woman is approaching obsession. And when Walter discovers that he's not alone in his search, one truth is certain: this deadly string of secrets didn't begin in his home city--but he's going to make sure it ends there.
