Used book – *Where Are You Now?*, Mary Higgins Clark

It's been ten years since Mack disappeared. Ten years since he's called his family every Mother's Day, without saying anything about himself. Not even his father's death in the 9/11 tragedy brought him back. His sister Carolyn decides to find him at all costs, despite the warning slipped to their uncle, a priest, in the church collection basket: "Tell Carolyn not to look for me." Her investigation leads her to the trail of several young girls murdered in the neighborhood where Mack lived. Is he the serial killer sought by the police or the victim of a horrible machination? A thrilling puzzle where Mary Higgins Clark muddles the tracks with a diabolical talent to draw us into one of her best suspense novels.
