The Prostitutes' Ball by Stephen J. Cannell

Enjoyable fluff. PW: Scully is assigned to the case along with his new partner, Sumner Hitchens. Hitch has a reputation in the department as a self-promoter; he sold the story rights to one of his cases to a film production company — and he has the millions to show for it. Scully and Hitch begin to investigate, and the case looks to be open-and-shut: The two young women were hired prostitutes, and there’s a security video of an angry husband firing on all three. A simple case of revenge.
