Food truck vendor Darcy Burnett unwraps a murder at the San Francisco Chocolate Festival in this mystery from the author of Death of a Crabby Cook... At this year's chocolate festival, Darcy and her Aunt Abby hope to win the $10,000 prize in the chocolate contest with Aunt Abby's taste sensation: the chocolate raspberry whoopee pie. A little friendly competition from Darcy's sometime-beau Jake Miller, who plans to enter with his chocolate cream puff delight, only sweetens the deal. But things get sticky when one of the judges, Polly Montgomery, is taken out of commission—permanently. The suspects include every contestant with reason to believe Polly wasn't too sweet on their sweets, including Aunt Abby's high school friend. Now Darcy must pick through an assortment of secrets to catch a killer before someone else gets a bittersweet finish.
