Mint chocolate murder

When Udderly Delightful Ice Cream shop manager Riley Rhodes is summoned to Penniman's Moy Mull Castle, it's the cherry on top of a successful summer season. The gothic pile built by an eccentric New England Gilded Age millionaire has been transformed into a premiere arts colony by Maud Monaco, a reclusive former supermodel. As part of Moy Mull's Fall Arts Festival, Maud is throwing a fantasy ice cream social and hires Riley to whip up unique treats to celebrate the opening of an exhibit by Adam Blasco, a photographer as obnoxious as he is talented. As Penniman fills up with Maud's art-world friends arriving for the festival, gossip swirls around Blasco, who has a dark history of obsession with his models. Riley's curiosity and instincts for sleuthing - she was a CIA librarian - are piqued, and she wonders at the hold the cold-hearted photographer has over the mistress of Moy Mull.
