Paris, France: September 1929. For Harris Stuyvesant, the assignment is a private investigator's dream - he's getting paid to troll the cafés and bars of Montparnasse, looking for a pretty young woman. The American agent has a healthy appreciation for la vie de bohème, despite having worked for years at the U.S. Bureau of Investigation. The missing person in question is Philippa Crosby, a twenty-two year old from Boston who has been living in Paris, modeling and acting. Her family became alarmed when she stopped all communications, and Stuyvesant agreed to track her down.

Soon it becomes clear that one missing girl is a drop in the bucket. Here, amid the glittering lights of the cabarets, hides a monster whose artistic coup de grâce is to be rendered in blood. And Stuyvesant will have to descend into the darkest depths of perversion to find a killer . . . sifting through The Bones of Paris.
