This 2017 Harry Bosch novel has a long-imprisoned killer claiming Harry framed him and seems to have DNA evidence to prove it.
Unable to retire, Harry is working cold cases for the San Fernando Police Department when hit with the accusation.
In parallel, Bosch is infiltrating a prescription opioid drug ring. Very interesting. The plot is great.
The only downside is Titus Welliver reading the audio book. For me he’s the weakest of the readers used in this series.
