Come Clean (1989)

Sarah Iles' latest young lover, Ian Aston, and the seedy gangland club he frequents both possess the intense attraction of the forbidden. When one night at the Monty they witness a fatal knifing, they unwittingly learn far too much for their own good of a deadly plot that could, if successfully executed, rearrange the city's criminal power structure. Immediately, the unfaithful wife and petty criminal become targets of both police and underworld observation. In Come Clean Bill James once again explores that no-man's-land of law enforcement, where human concern and naked expediency stand perennially at odds with each other.
