Bosch needs to find out who was responsible for what happened to Daisy Ballard needs to work a case with teeth, even if she’s partnering with a reserve investigator in the San Fernando Police Department ( Two Kinds of Truth, 2017, etc.) who’d rather work alone. On the night Bosch drops into Hollywood Division to sneak a look at some of the old files, he’s caught by Detective Renée Ballard, who was bounced from LAPD Robbery/Homicide to “the late show,” Hollywood’s third shift, after her complaint about aggressive harassment by a superior went nowhere. It may be nine years since 15-year-old runaway Daisy Clayton was grabbed from the streets of Los Angeles and killed, but the daily presence of her mother, Elizabeth, in Harry’s life-she’s staying at his place while he helps her stay clean-makes it a foregone conclusion that he’ll reopen the case. Harry Bosch, who just can’t stay retired, unwillingly teams up with a Hollywood detective who has reasons of her own for wanting in on his latest cold case.
