Their dynasty goes back several hundred years. But instead of being noblemen, they’re crooks. Now, after generations of respectable thievery, one family member dares to defect to the enemy: 21-year-old Betty, who’s secretly joined the police force. After all, she knows what criminals think, how they feel and act. Trying to help her family without slipping into illegality and without her family’s knowing anything about her real job is a tall order to fill. But Betty’s so skillful at it that she’d make a great crook herself. It must be in the genes!
