STIRRING UP TROUBLE   Snowflake, Vermont, is known for its skiing in winter—and its soup all year round, thanks to Lucky Jamieson’s By the Spoonful. Autumn brings golden leaves, pumpkin rice soup, the annual Harvest Festival…and murder.   Lucky’s soup shop is busier than usual this October, with groups of itinerant travelers in town to work the Harvest Festival. One newcomer seems to take a particular interest in Lucky’s young waitress, Janie, spying on her from across the street. Is the stranger stalking Janie?   After an unidentified man is found murdered in a van by the side of the road, simmering suspicions about the travelers are brought to a boil. But when Janie is put in harm’s way, Lucky must join forces with the travelers to turn up the heat on a killer…   Recipes included!
