The famous Saddlebred show in Shelbyville, Kentucky, is the perfect opportunity for remarried newlyweds Harry and Fair Haristeen to finally go on their long-delayed (second) honeymoon-a chance to combine business and pleasure, as well as to drop in on some old friends. Mrs. Murphy (a tabby cat), Tucker (a Corgi), and Pewter (a fat gray kitty) are all along for the trip as well, and when their hosts are robbed the very first day they arrive, Mrs. Murphy pounces right on solving the mystery. Soon, however, they are all sidetracked by even bigger crimes: a $200,000 mare owned by a young film star is stolen in broad daylight, and worst of all, a groom is found murdered. Clearly, winning at Shelbyville is secondary; first prize is survival.
