At the Crossroad — Amy M. Bennett

You can take the cop out of the big city, but you can't take the big city out of the cop, in this fourth Black Horse Campground mystery.
 
Just as Corrie is getting used to having former Houston, Texas, narcotics detective J. D. Wilder as a campground employee, he officially becomes a member of the Village of Bonney Police Department. Aside from a recent crime spree at the Black Horse, not much is going on in town, giving Wilder a chance to go over some cold cases.
 
In the past fifteen years, three women have gone missing, exactly five years apart. What has amounted to nothing more than a local urban legend becomes Wilder's new obsession -- with Corrie offering some much-needed background information. As he's digging into the neighborhood's recent history, trouble from his own shows up, forcing the shadowy past into a deadly confrontation with a clear and present danger . . .
