Gus Ramone is "good police," a former Internal Affairs investigator now working homicide. His new case involves the death of a local D.C. teenager named Asa. The murder unearths intense memories of a case Ramone worked as a patrol cop 20 years earlier, when he and his partner, Dan "Doc" Holiday, assisted a legendary detective named T. C. Cook. The murders, all involving local teenagers with palindromic names, were never solved. The new case draws the three men together, re-igniting the love, regret, and anger that once burned between them.
