Another Harry Bosch novel from Connelly! Fantastic.
Harry is now retired, but a volunteer working cold cases for the San Fernando police. Due to his experience he is pulled into the case of two killings at a local pharmacy. Bosch and the town small detective squad work this case at the same time as one of his old cases comes back to haunt him.
In the old case a murderer is about to be freed from death row due to new DNA evidence but also claiming that Bosch planted evidence.
As ever with Connelly the “two unrelated cases wind around each other like strands of barbed wire”.
