Selling her corn fritters at a carnival, Deputy Donut Café owner Emily Westhill faces off against a murderer who doesn’t play fair . . .

Emily and her assistant, Nina, are looking forward to manning the Deputy Donut tent at the Faker’s Dozen Carnival in Fallingbrook, Wisconsin—a festival held on Friday the thirteenth to celebrate good and bad luck. But Emily has barely dropped the corn fritters in oil when bad luck boils up. First, their bucket of confectioner’s sugar disappears—and then, while a mime creates a distraction, a magician robs their cash register.

After the carnival, their misfortune continues. Emily discovers that someone has broken into artist Nina’s loft and vandalized a large painting in progress with a bucket of stolen sugar, which is now on the head of the mime, who seems to have been suffocated. Emily would bet Nina was the intended victim, but the cops think Nina silenced the mime. Now Emily must catch the killer white-handed—before someone else kicks the bucket . . .
