Murder at the Marathon

As part of his effort to get his life back together, Pereira takes up jogging and decides to run in the New York City Marathon. During the race, a runner next to him apparently has a heart attack and dies. The man's girlfriend, a high-class call girl, convinces Pereira it was murder. Former detective Pereira sets out to prove her right and discovers the man's death is part of a tangled web of power and greed involving the head of a major technology company, the mob, and a city official sworn to uphold the law.
