I, Alex Cross: (Alex Cross 16)

In James Patterson's number one bestselling series, Detective Alex Cross pursues his niece's killer-and not even Washington's most restricted corridors of power can keep him from the truth. But his investigations reveal facts he would rather not know about his niece - she was a high-class prostitute at an expensive and exclusive club located just outside of Washington DC. As more women working at the same club disappear, it becomes obvious that there is more going on at the sordid mansion than illegal prostitution, and Cross will stop at nothing to solve the mystery of these brutal and sadistic murders.
