The Glass Rainbow — James Lee Burke

The brutal murders of seven young women in a neighboring parish pull Robicheaux from his New Iberia home into a case with all the telltale signs of a serial killer. Except that one of the victims, a high school honors student, doesn't fit. Investigating with his friend Clete Purcel, Robicheaux confronts Herman Stanga, a notorious pimp and crack dealer -- but shocking violence sends the already blood-soaked case spiraling out of control. And with his daughter, Alafair, in love with a man with dangerous ties to a once prominent Louisiana family, every dark fear Robicheaux harbors for himself and his daughter is on the precipice of becoming reality.
