Sweater shop owner Paislee Shaw puts the yarn in Nairn, but a killer has put poison in some Scottish shortbread cookies . . .
Opening her shop Cashmere Crush and making a new home for herself, her son Brody, Gramps, and their black Scottish terrier Wallace in the beautiful Scottish village of Nairn, is a dream come true. So Paislee is happy to give back by donating a luxurious cashmere sweater for an auction to raise money for the Nairn Food Bank. She's less happy to make the acquaintance of a clique of competitive moms at the charity event, who treat a baking contest like it's life or death. It turns out to be the latter for queen bee Kirsten Buchanan when a peanut-laced shortbread cookie triggers her fatal nut allergy.

Who would poison Kirsten? How about half the town? But when Paislee's pal Blaise is suspected, the sweater-selling sleuth leaps into action to unravel the mystery. Along with gruff but handsome DI Mack Zeffer, she has to sort through a batch of suspects without becoming this cookie-cutter killer's next target . . .
