“The Waiting,” by Michael Connelly. Renée Ballard and her Open-Unsolved Unit have been combing through cold case files when DNA collection of a recently arrested man is found to have a link to a case from 20 years prior. The arrested man is only 24 so he cannot be the serial rapist and murderer police were once on the hunt for. But genetics don’t lie so Ballard and her team look to the man’s father, who, uh oh, just happens to be a presiding judge of superior court. Complicating matters is Ballard’s loss of her police ID, badge and service weapon following a break-in of her car. Instead of reporting the incident, Ballard decides she is going to conduct her own investigation. She finds the thief and the fence; however, she may also have stumbled upon a terrorist plot. But how do you tell your boss without also informing them you made the discovery because you lost your gun, badge and police ID? Or the fact you kept mum about it? Meanwhile, a member of Ballard’s team, Maddie Bosch, a patrol officer who’s chomping at the bit to make detective, may have just solved one of the coldest, and most infamous killings in LA: the Black Dahlia murder.
