Maddie gets rattled by a candy-coated murder.

It's Wine and Chocolate Days in San Benedetto, and paranormal museum owner Maddie Kosloski has sweet dreams about her new Magic of Chocolate exhibit. Her latest attraction is a haunted Mexican whisk called a molinillo that rattles if someone lies.

When Maddie visits the town's new boutique chocolate shop, she finds one of the owners dead and covered in melted cocoa. Maddie's determined to catch the killer, and she soon uncovers deadly dealings in the world of artisan chocolate. But the deception surrounding those dealings are enough to make the molinillo rattle all night. Will Maddie have to temper her passion for sleuthing before a killer makes her fate bittersweet?
