Query: Cop w/BIG personal problems solves mother's 30 yr old murder

Another Harry Bosch mystery. All of the plot twists and Harry's ongoing angst about himself, his life, his view of the world. He trolls through the nasty underside of politics and police work, digging to find the killer of his mother - 30 years ago when he was 12. Best line: he finds the cop who informed him that his mother was dead. The cop thinks that Harry's after him about the loose ends on the incident and has a gun on Harry. Harry tells the cop how he found Harry at a swimming pool to tell him. The cop says "you're the kid" and Harry answers "I'm the kid". (I love scenes that echo something that happened years before). Anyway, a very good read, and several sets of false clues, just to keep you guessing.
