In the course of the investigation, Spenser encounters Jumbo's bodyguard: a young, former football-playing Native American named Zebulon Sixkill. He acts tough, but Spenser sees something more within the young man. Despite the odd circumstances, the two forge an unlikely alliance, with Spenser serving as mentor for Sixkill. As the case grows darker and secrets about both Jumbo and the dead woman come to light, it's Spenser-with Sixkill at his side-who must put things right.
