Business is booming for Libby Beckett and her fabulous Maryland shop, aptly named Y.A.R.N., but when a town festival brings a fatality with it, Libby gets all tangled up in murder.

As fall comes to Collinstown, the village launches a food festival to draw a new group of tourists. Libby, proud owner of Y.A.R.N, has planned a special yarn event to give an alternative option to a foodie weekend. Artisan fiber dyer Julie Wilson-known for her work with animal free fibers such as bamboo and hemp, as well as her brilliant use of color -will hopefully draw a crowd with a special dyeing workshop.

The festival begins, but it draws more than crowds. First a flock of sheep parade down the street, herded by farmers protesting Julie's anti-wool stance. Then Julie's celebrity chef sister appears and the siblings continue a long-standing rivalry. But despite all this, Julie's workshop has sold out. Libby is thrilled, and they're preparing for a full house. But the night before the event, Julie is found alone in the warehouse event space, dead. The witty "Watch Julie Dye" seminar title now has a terrible new meaning-and it's up to Libby to catch a crafty killer.
