Howard Drew, an unrelenting LAPD homicide detective assigned to the Open Unsolved Unit, investigates the murders of victims long dead. He prowls moral fault lines and assumes the perspectives of his victims and their killers. Drew waits, poised to listen when guilty people divulge information and tired people fold and betray their secrets. Drew also listens to the chorus of forgotten voices and speaks for them because the collective dead demand it. But in cold case homicide investigations, appearances can be deceiving. Truth can be slippery.
