After sponsoring a charity dirt bike race, the Foundation receives information that the deadly crash in last year's event was the result of murder. More specifically, the death of Danny Duvall, a champion endurance racer. At the track, Michael learns Duvall had enemies; namely Lee Carstairs, (a flamboyant, highly-promoted racer), and Wade Fontane, (a jealous hothead who wants Duvall's girlfriend Sabrina Travis). Sabrina is also the sister of Kelly Travis, a fellow racer and Duvall's best friend. Kelly was injured in the crash and nearly paralyzed, but Michael is impressed that he still has the will to race.
