Jessie O'Bourne is delighted to be the invited guest artist at the Crooked Creek Art Expo held annually in Montana during March. Mother Nature is still blasting the area with snow and ice, however, so Jessie moves herself and her tomcat, Jack, out of her cold, but beloved motorhome, the Hawk, into the warmth and luxurious accommodations of the old log lodge hosting the art show. When Jessie discovers a dead body was hidden in the Hawk during her absence, she's thrown into a complex murder investigation tied to the death of a teenager. Soon, threatening notes and tiny toy tractors are delivered to her door and she calls on her big Norwegian friend, Detective Sergeant Arvid Abrahmsen, and old flame, Sheriff Russell Bonham, of Sage Bluff, to help investigate. Surrounded by painters and sculptors, Jessie is horrified to think that one of her talented friends is a killer. FBI art theft agent, Grant Kennedy, arrives in Crooked Creek to attend the auction and joins forces with Arvid and Russell. Their goal is to find the murderer before the latest death threat slipped under Jessie's door becomes a reality.
