Kinjo Heywood is one of the New England Patriots' marquee players-a hard-nosed linebacker who's earned his reputation as one of the toughest guys in the league. When off-field violence repeatedly lands Heywood in the news, his slick agent hires Spenser to find the men who he says have been harassing his client. Heywood's troubles seem to be tied to a nightclub shooting from two years earlier. But when Heywood's nine-year-old son, Akira, is kidnapped, ransom demands are given, and a winding trail through Boston's underworld begins, Spenser puts together his own all-star team of toughs.
