A Harry Bosch novel with a large dose of Bosch's half-brother, Mickey Haller. As always, Michael Connelly grabs my attention and doesn't let go until the very last page. Can't say enough good things about him.
Here, Harry has obtained his private investigator license, so he's joining the ranks of Marlowe, Archer, Cole, and Millhone, going down the mean streets, the best man in his world, and a good enough man for any world. Even the book's title sounds one that Chandler might have used. And the initial premise recalls The Big Sleep: Bosch is summoned to the mansion of an aged tycoon! His gig is slightly different, though: the tycoon has a long-lost biological son, product of a late-1940's dalliance with a Mexican girl. Sensing his mortality, the tycoon now wishes to make things right, as best he can, by hiring Harry to locate the kid. And Harry is warned that people who would prefer that the heir not be found might resort to some nasty behavior to obstruct him.
That's one plot thread. In the other, Harry is volunteering his detective services to the city of San Fernando PD. San Fernando is a mere 2.37 square miles in area, completely surrounded by Los Angeles, mostly Hispanic population. Harry has linked together previously-unconnected rape cases to discover their common perpetrator, who the cops have dubbed the "Screen Cutter". The villain seems confident in his ability to perform his crime without getting caught. Which, of course, puts Harry's teeth on edge.
Technically, Harry's not supposed to use SFPD resources in his private investigation. Of course, he does anyway.
