LAPD's finest, Harry Bosch, and his half-brother, maverick defence lawyer Micky Haller, alternately 'guest-star' in each other's cases. This is a Bosch story, in which Harry, now retired from the Police Department, reluctantly crosses 'to the other side' to help Micky liberate a client who's been framed for the savage murder of a deputy sheriff's wife. Harry, of course, spots a seemingly trivial detail at the crime scene that the investigators have overlooked and which cracks open the case and unleashes more killings.
Connelly includes brief scenes featuring two 'rogue' members of the squad, so this is not so much a Whodunit as a Will-they-catch-'em. The investigation builds to a violent climax with Harry once more staring down a gun barrel.
This is Number Twenty in the Bosch series. Some of them have been outstanding: The Concrete Blonde and Echo Park are my personal top two. The Crossing is slightly run-of-the-mill, but anything from Michael Connelly's word-processor guarantees a taut, tense read.
