Alex Cross was a rising star in the Washington Police Department when an unknown shooter gunned down his wife, Maria, in front of him. The killer was never found, and the case turned cold, filed among the unsolved drive-bys in D.C.'s rough neighborhoods. Years later, still haunted by his wife's death, Cross is making a bold move in his life. Now a free agent from the police and the FBI, he's set up practice as a psychologist once again. Then Cross's former partner, John Sampson, calls in a favor. He is tracking a serial rapist in Georgetown, one whose brutal modus operandi recalls a case Sampson and Cross worked together years earlier. When the case reveals a connection to Maria's death, Cross latches on for the most urgent and terrifying ride of his life
