La 4ème de couv. indique : "If the truth doesn't get him. Harry Bosch volunteers on cold cases for a small police department outside LA. When a rare double murder shakes the town, the local detectives look to Bosch. Their investigation will expose a sinister network hiding in plain sight, leaving a trail of broken lives in its wake. The lies will. But before Bosch can find justice for the victims, he must find it for himself. Because a death row prisoner is claiming Bosch framed him - and that new DNA evidence proves it. The case seems watertight, leaving Bosch out in the wilderness with only one person to help clear his name : Mickey Haller, The Lincoln Lawyer. As past and present tangle around him, Bosch faces two kinds of truth : the kind that won't die and the kind that kills."
