In the latest thriller featuring the legendary Boston PI, Spenser and his young protégé Mattie Sullivan take on billionaire money manager running a network of underaged girls for his rich and powerful clients. Ten years ago, Spenser helped a teenage girl named Mattie Sullivan find her mother's killer and take down an infamous Southie crime boss. 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.

Boston PI Spenser faces a hot case and a personal crisis in this adventure in Robert B. Parker’s iconic New York Times bestselling series. The fire at a boarded-up Catholic church raged hot and fast, lighting up Boston’s South End and killing three firefighters who were trapped in the inferno. A year later, as the city prepares to honor their sacrifice, there are still no answers about how the deadly fire started. Most at the department believe it was just a simple accident: faulty wiring in a century-old building. But Boston firefighter Jack McGee, who lost his best friend in the blaze, suspects arson. McGee is convinced department investigators aren’t sufficiently connected to the city’s lowlifes to get a handle on who's behind the blaze—so he takes the case to Spenser. Spenser quickly learns not only that McGee might be right, but that the fire might be linked to a rash of new arsons, spreading through the city, burning faster and hotter every night. Spenser follows the trail of fires to Boston’s underworld, bringing him, his trusted ally Hawk, and his apprentice Sixkill toe-to-toe with a dangerous new enemy who wants Spenser dead, and doesn’t play by the city’s old rules. Spenser has to find the firebug before he kills again—and stay alive himself.
