Death on D Street — Kristine Kathryn Rusch

D Street -- the closest thing Hope's Pass has to a red light district. Three whorehouses and a few independents to service the miners who survived the mines outside of town.
When someone murders a prostitute, Will, the mayor, must fill in for the drunken sheriff and investigate the crime. Only the crime has deep roots -- roots that will touch Will's entire family and make him question everything he has ever known.

“Kristine Kathryn Rusch's crime stories are exceptional, both in plot and in style.”
