Riveting and constantly accelerating, The Black Box is the most profound case yet for the unrelenting Harry Bosch.

Los Angeles, May 1992. Murder just got a whole lot easier. And investigating them got a whole lot harder.

After four LAPD officers were acquitted after the savage beating of Rodney King, LA is ablaze. As looting and burning take over the city, law and order are swept away in a tidal wave of violence. But under threat of their lives, homicide detectives like Harry Bosch are still stubbornly trying to do their job.

When Harry finds the body of a female journalist in an alley - apparently executed - he is forced to hand the case over to the Riot Crimes Task Force, knowing that it will never be solved.

Twenty years later, Harry has still not forgotten the woman for whom he was unable to deliver justice. New ballistic evidence now confirms her death was not a case of random violence but something much more personal. This time Harry is determined that the killer isn't going to escape - even if it means stepping back into the darkest days of the city he loves.
