The discovery of an unconscious man named Diamond in Central Park leads Greevey and Logan to Diamond's previous activity and locale—with an escort named Jolene in a hotel room. Greevey poses as a "john" looking for Jolene. When she stipulates her fees and services, Greevey arrests her for solicitation. When Diamond dies, the investigation leads to Jolene's superior, Jasmine, then to Jasmine's superior, Laura Winthrop. Winthrop claims that she runs a catering service, but when Jolene's blood tests HIV-positive, the case takes a sharp tack questioning the safety of the escort service industry.
