Artist Amanda Trent, accompanied by her beloved golden retriever Laddie and her persnickety calico cat Mona Lisa, is determined to start a new life after her husband divorces her to marry a younger woman, but it isn't easy.

After a disastrous interview at the prestigious Roadrunner Gallery in Lonesome Valley, Arizona, far away from her previous home in Kansas City, Amanda's afraid that she'll fail at her new career. But her prospects begin to improve when she's accepted as the newest member of the cooperative gallery.

Then, on her very first day, she discovers Janice, the stern director, has been murdered right in the art gallery, and the Roadrunner's members, including Amanda herself, become suspects. Which gallery member murdered the unpopular director? Or was the killer an outsider with an ax to grind?
