The City PI and the Country Cop by Edward Kendrick

As Teague Donovan, a PI, and Hoyt Newman, a small town deputy, work together to solve a series of murders involving homeless boys, they begin to develop an interest in each other. One that seems fated not to come to fruition since Teague is city, through and through, and Hoyt is definitely country to the core.

A murder in a small Colorado town closely resembles unsolved crimes committed by a serial killer almost thirty years ago. Private investigator Teague Donovan learns of the recent murder and is instantly drawn to the case, because one of the victims in the past was his best friend, and he is determined to bring the killer to justice.

Hoyt Newman, the detective in charge of the most recent case, is none too happy with Teague's interfering. At least not until a second homeless boy is tortured and killed. As the two men work together, they begin to develop an interest in each other -- one that seems fated not to come to fruition since Teague is city, through and through, and Hoyt is definitely country to the core.
