In Michael Connelly’s NINE DRAGONS, Detective Harry Bosch, who works in the Robbery-Homicide Division of the Los Angeles Police Department, is sent with his partner to investigate a “rob job” at a liquor store that resulted in the shooting death of the proprietor, John Li. After speaking to Li’s family and viewing surveillance discs, Bosch comes up with two theories. Either a teenage shoplifter who was banished from the liquor store committed the crime, or a member of the Chinese Triad (thugs who extort money and engage in other illegal activities) killed Li for refusing to pay protection money. For a variety of reasons, Bosch leans towards the second explanation. When he realizes that his ignorance of Chinese language and culture might impede his investigation, Harry enlists the aid of Detective David Chu to interview witnesses and provide him with relevant background information.
