Showing Murder in the Rue Dauphine by Greg Herren

A simple blackmail case goes south when Chanse finds the murdered body of his muscleboy client in what appears to be a hate crime. But neither Chanse nor the police are convinced it was a hate crime, despite the frenzy being whipped up in the city by a charismatic but attention-seeking gay rights activist. The trail leads to a call boy ring, blackmail of wealthy Uptown closet cases, and it's not long before Chanse's investigation has put not only his life at risk, but that of everyone he cares about!

The first Chanse Macleod mystery.
