Now Mattie--a college student with a side job working for the tough but tender private eye--dreams of being an investigator herself. Her first big case involves a fifteen-year-old girl assaulted by a much older man at one of Boston's most prestigious private clubs. The girl, Chloe Turner, only wants the safe return of her laptop and backpack. But like her mentor and boss, Mattie has a knack for asking the right questions of the wrong people.Soon Spenser and Mattie find ties between the exploitation of dozens of other girls from working class families to an eccentric billionaire and his sadistic henchwoman with a mansion on Commonwealth Avenue. The mystery man's wealth, power and connections extend well beyond Massachusetts - maybe even beyond the United States. Spenser and trusted ally Hawk must again watch out for Mattie as she unravels a massive sex-trafficking ring that will take them from Boston to Boca Raton to the Bahamas, crossing paths with local toughs, a highly-trained security company, and an old enemy of Spenser's--the Gray Man--for a final epic showdown.
