The Heckler: The precinct faces its most bewildering puzzle when an anonymous prankster begins a targeted campaign of harassing telephone calls across the city. But what looks like a series of cruel mind games is actually the opening moves of a massive, cold-blooded heist engineered by a criminal mastermind.

See Them Die: The neighborhood gangs are mobilizing, a heatwave is pushing tensions to a boiling point, and a notorious, heavily armed criminal is trapped inside a crowded tenement building. The detectives of the 87th must close the dragnet before a lethal, explosive gunfight tears the neighborhood apart.
