Coming out of retirement to help his defense attorney half-brother prove that a client has been framed for murder, Detective Harry Bosch secretly teams up with former partner Lucia Soto to investigate possible corruption inside the LAPD.

"Detective Harry Bosch has retired from the LAPD, but his half-brother, defense attorney Mickey Haller, needs his help. The murder rap against his client seems ironclad, but Mickey is sure it's a setup. Though it goes against all his instincts, Bosch takes the case. With the secret help of his former LAPD partner Lucia Soto, he turns the investigation inside the police department. But as Bosch gets closer to discovering the truth, he makes himself a target"--

Six months ago, Harry Bosch left the LAPD before they could fire him, and then hired maverick Defense Attorney Mickey Haller to sue the department for forcing him out. Although it wasn't the way he wanted to go, Harry has to admit that being out of the game has its benefits. Until Mickey asks him to help on one of his cases, and suddenly Harry is back where he belongs, right in the centre of a particularly puzzling murder mystery. The difference is, this time Harry is working for the defense, aiming to prevent the accused, Leland Foster, from being convicted. And not only does the prosecution seem to have a cast-iron case, but having crossed over to 'the dark side' as his former colleagues would put it, Harry is in danger of betraying the very principles he's lived by his whole career.
