The Makings of a Good Man by Lietha Wards

Alpha male-beautiful, innocent heroine.

Beth Winters had a secret. Something that she couldn't share with anyone, but when they moved to a small town in Montana, it was in jeopardy of being known, especially when her father forced her to take a job with a local cattleman. Marshal Davis had the way of finding the truth in anything, and his attraction to Beth made him more determined to get to the bottom of things.
