Death of the Black Widow

She destroys the men she loves and escapes every time. The most dangerous killer James Patterson has ever created is also his most seductive.
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’s 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.   
"If someone were to ask him, Walter O’Brien would say no. But that was exactly what the square brick structure on the corner of Park and Woodward in downtown Detroit appeared to be doing. The faded red brick had a dull sheen on it, the moisture reflecting the streetlights, the neon from the sign above, and the headlights of the cars as they rolled by, oblivious to what was coming."
