Rejoice. Michael Connelly has brought out a new Harry Bosch novel. Except Harry’s getting long in the tooth (apparently he’s grown his mustache back too. I’m pretty sure he shaved it off a few years back), and is not technically an LAPD detective at all anymore. So in Dark Sacred Night he teams up with Connelly’s new detective character – surfer chick-detective Renee Ballard, heroine of The Late Show.

Renee is the victim of sexism in the department, and has been exiled to the “the late show,” the night shift. Surprisingly, she’s found she kind of likes that shift. She’s surprised when she sees an older cop rummaging in a filing cabinet one night. She learns that it’s Harry Bosch, who’s investigating a cold case – the murder of an underage prostitute, Daisy Clayton. Harry knows Daisy’s mother, who is a drug addict and recently cleaned herself up. She’s living with Harry right now, and he promised her he’d try to find the killer. When Renee learns about it, she wants in, and Harry and she find they work pretty well together. They’ll need that synergy when the case gets dangerous, and the brass interfere.

Not the best of a long series, Dark Sacred Night is a satisfying but somewhat downbeat visit with an old friend, professionally delivered. Recommended with the usual cautions.
