Six months ago, Rourke Kincaid failed to follow procedure and a civilian almost died. He was pulled from active duty; eventually assigned to cold cases. After reviewing several files, U.S. Marshal Rourke Kincaid notices a serial killer pattern in the files; Beartooth, Montana waitress Callie Westfield was photographed at various Sweetgrass County crime scenes. He wonders why she keeps showing up but instead of supporting his premise, his supervisor suspends him again.
Unauthorized Rourke goes rogue and in Seattle meets with his medically retired former SPD partner Laura Fuller to illicit her help. Laura hopes he came to see her to tell her he loves her like she does him; but instead he asks her to assist him on a serial killer case in Beartooth. In the Montana town, undercover Rourke meets Callie at the Branding Iron Café where she works. However, as the evidence mounts that Callie is a cold-blooded murderess, mortified Rourke knows he fell in love with a serial killer.
The fifth Beartooth Mountains thriller (see Atonement, Unforgiven, Forsaken and Redemption) is a pleasing Big Sky romantic suspense. Although readers will solve the case much earlier than Rourke does, Mercy is a fast-paced, action-packed murder mystery.
