2Birdie, Nell, Cass, and Izzy are prepping their coziest handiwork for a holiday gathering in Sea Harbor, Massachusetts. But as murder makes waves in their tightly knit coastal village, can the Seaside Knitters prevent a deadly trend from catching on?

While the Seaside Knitters get ready to showcase their new Danish-inspired event, locals can't stop talking about Tess Bean--a bright-eyed environmental activist with a way of charming both animals and humans alike. Birdie's granddaughter is mesmerized by ethereal Tess's passion for saving the earth and ocean, and even Izzy's old Irish setter becomes attached to the young woman's gentle touch . . .

Except not everyone is a fan of Tess and her strong opinions, especially after she starts questioning the "clean" practices of small-business owners. So when a popular bar owner whom Tess publicly calls out for bad practices is found dead from a fall off his club's deck, it's not long before she tops the suspect list for murder . . .

In addition to a murderer walking their streets, the knitters are also grappling with an unusual wave of thefts up and down Harbor Road. Now, as Birdie's granddaughter struggles to protect her mentor's reputation, the Seaside Knitters must solve a dangerous mystery that not only threatens to unravel the fabric of their community and the approaching holiday, but also the lives of those they care about the most . . .
