The residents of tiny Crozet, Virginia, thrive on gossip, especially in the post office, where Mary Minor "Harry" Haristeen presides with her tiger cat, Mrs. Murphy. So when a belligerent Hell's Angel crashes Crozet demanding to see his girlfriend, the leather-clad interloper quickly becomes the chief topic of conversation. Then the bider is found murdered, and everyone is baffled. Well, almost everyone ... Mrs. Murphy and her friends, Welsh corgi Tee Tucker and overweight feline Pewter, haven't been slinking through alleys for nothing. But can they dig up the truth in time to save their humans from a ruthless killer?
