It was Kiz who helped to persuade him back into the blue religion. Harry and Kiz are assigned to the LAPD's Open-Unsolved Unit. These detectives are the Closers; they put a shovel in the dirt and turn over the past. Harry and Kiz are thrown into a politically sensitive and dangerous case when a DNA match connects a white supremacist to the 1988 murder of a mixed race 16-year-old girl. These were the days before Rodney King, but the powder keg of hatred was merely waiting for the match. Harry finds a police department far different from the one he left three years earlier. A new Chief has been brought over from New York to change the bad old culture of corruption - or that's the theory. But one thing hasn't changed - Harry's nemesis, Irvin Irving. The former Deputy Chief has been pushed from power. Full of vengeance, Irving calls Harry a 'retread'. He watches from the sidelines, hoping Harry will make a mistake ...like a speeding bullet and never slows down for a moment.
