Banana Cream Murder - Bitsie's Bakeshop Culinary Cozies, #4

Sometimes, baking gets a little too competitive. Occasionally, it turns deadly. When Bitsie is confronted by a faded celebrity baker claiming that Bitsie has stolen the woman's prize banana cream frosting recipe, Bitsie tries to shrug off the incident as being the ravings of an unhinged has-been. But instead fading from view, the frosting-obsessed eccentric becomes the central figure in not one but two suspicious deaths in Little Creek.
Joined by her semi-retired police officer brother, Stan, and her too-handsome-to-be-real bakeshop assistant, Nick, Bitsie uses her natural nosiness to see that justice is served, and no sweet-tooth in Little Creek is left unsatisfied.
