Joe Gores: Interface (UK 2004)
From the Publisher:
Neil Fargo is a San Francisco private investigator hired by the wealthy Maxwell Stayton to find his missing daughter. His search takes him into the very heart of the city's ugly underbelly. And Fargo makes the move into the drug business at just about the same time as Docker, a Vietnam veteran with close links to Fargo, is storming through San Francisco's criminal underworld on a murderous campaign of revenge.
