One Dead Cookie by Virginia Lowell

Olivia Greyson is the proud owner of The Gingerbread House--a quaint shop that specializes in all things cookie--and her best friend, Maddie, is her sidekick, baking up scrumptious treats for their cookie-themed parties. But a dead body on their front porch might put their bake shop in a truly sticky situation...
Olivia is busy baking up special cookies for Maddie's upcoming engagement party when soap star Trevor Lane shows up unexpectedly in town. It soon becomes clear that Trevor, who grew up in the neighboring town of Twiterton, left behind a number of enemies with long memories. Even Trevor's assistant and childhood friend, Dougie, seems to harbor a grudge against him.
Soon after his arrival, Trevor is found dead on The Gingerbread House porch, his handsome face branded with the image of a cookie cutter. When their friend Stacey is implicated in the murder, Olivia and Maddie rush to find the killer. Because it seems someone in Chatterley Heights has a sweet tooth for revenge...
