For maverick LAPD homicide detective Harry Bosch, the body in the drainpipe at Mulholland Dam is more than another anonymous statistic. This one is personal...because the murdered man was a fellow Vietnam "tunnel rat" who had fought side by side with him in a hellish underground war. Now Bosch is about to relive the horror of Nam.

Two women have gone missing, and LAPD detective Harry Bosch has a strong suspicion that an avid fisherman named Denninger is the culprit. Bosch needs something stronger than a suspicion to bring Denninger in, but all he has are a handful of photos - prior mug shots and pictures of Denninger posing with his prize fish. It's not much to go on, and Bosch is running out of time, which is why he calls in FBI agent Rachel Walling. What she sees in these photos could blow his case wide open.

On the night he celebrates a big win, defense attorney Mickey Haller is pulled over by police, who find the body of a former client in the trunk of his Lincoln. Haller is immediately charged with murder but can’t post the exorbitant $5 million bail. Mickey elects to represent himself and is forced to mount his defense from his jail cell in downtown Los Angeles. Even if he can obtain a not-guilty verdict, Mickey understands that it won’t be enough. In order to be truly exonerated, he must find out who really committed the murder and why. That is the law of innocence.
