The nude photo of a teenage runaway shows up on a pornographic website, and the girls father turns to Detective Chief Inspector Alan banks for help. But these are typical circumstances, for the runaway is the daughter of a man whos determined to destroy the dedicated Yorkshire policemans career and good name. Still it is a case that strikes painfully home, one that Banks a father himself dares not ignore as he follows its squalid trail into teeming London, and into a world of drugs, sex, and crime. But murder follows soon after gruesome, sensational, and, more than once pulling Banks in a direction that he dearly does not wish to go: into the past and private world of his most powerful enemy, Chief Constable Jimmy Riddle.
