An unlikelier threesome there may not be. Chief Frank Shapiro's brand of leadership, while not flashy or heroic, is nevertheless unquestioned. Inspector Liz Graham has risen in the ranks higher and faster than most women in the British police system, and has had to allow the boys of Castlemere CID time to get used to her - most especially Sergeant Cal Donovan, whose surly Irish manner means his bark is just as bad as his bite. A year into their partnership, the relationships among the three may be quirky, but they are rock solid - that is, until Shapiro is suspended because new evidence in an eight-year-old arson case suggests that he sabotaged the investigation. No matter how much Liz and Cal want to believe their chief, an innocent man has served eight years in jail, and someone is responsible.
