The Fourth of July is coming, and for Samantha Barnes, it's all about the picnic. Sam has finally found the perfect recipe in the kitchen of cookbook author Clara Foster, and she's thrilled when Clara agrees to a baking lesson. But when Clara dies in a fire blamed on carelessness in the kitchen, Sam doesn't believe it. A cousin of Sam's boyfriend is a suspect, so in this third case (following An Eggnog to Die For), Sam needs to find a killer before the fireworks really start.
