Kent Conwell - Tony Boudreaux 08 - Death in the French Quarter

A Melungeon beauty, the sister of an old boyhood chum, comes to private eye Tony Boudreaux, hoping he can help clear her brother's name. Tony takes the case out of a sense of loyalty but has no idea that the trail will lead to the underbelly of smuggling and drugs in the seamy intrigue of New Orleans's gangland and to the man responsible for the professional execution of his young cousin several months earlier.
Forced to go undercover, Tony fashions a cover story that will usher him into the confidence of Bones Guilbeaux, the cold-eyed leader of a diabolical band of smugglers who kill without compunction. His pursuit of the killer leads him through a labyrinth of dark halls, hidden courtyards, secret rooms, and narrow passages where he frantically tries to stay one step ahead of those he pursues.
