Nine Dragons: Michael Connelly

Detective Harry Bosch is called to investigate the murder of a store owner in a tough LA neighbourhood. For Harry, it's a trip down memory lane: he's been to Fortune Liquors before and remembers Mr Li - a man who offered him sanctuary during LA's notorious riots. Now the debt must be repaid.
Mr Li left a clue to his murderer's identity, a clue that leads Harry into a parallel criminal universe ruled by the Triads. But as he gets closer to this shady underworld, the Triads send Harry a devastating message - they have taken something of his, something he holds very dear. As Harry's life implodes, he must risk everything to track a killer who knows how to get under his skin...
