When a heartbroken Samantha “Sammy” Kane returns to her hometown of Heartsford, Wisconsin, for her best friend Kate’s funeral, she learns that Kate’s much-loved craft store is in danger of perishing with its owner. Confounding all her expectations of the life she would live, Sammy moves back home with her golden retriever and takes over Community Craft. A few doors down Main Street, fellow new arrival Ingrid Wilson has just opened the Yarn Barn, a real “purl” of a shop. But when Sammy strolls over to see if Ingrid could use a little help, she finds Ingrid’s dead body - with a green aluminum knitting needle lodged in her throat.

Detective Liam Nash is thrown for a loop as every single citizen of Heartsford seems to have a theory about Ingrid’s murder. And nearly everyone in town seems to be a suspect. But the last time Sammy did any sleuthing was as a little moppet. And this is not fun and games. She is eager to help the handsome Liam - who seems to be endlessly inventive in finding reasons to talk with her - and when Liam arrests affable woodworker Miles Danbury, she puts everything on the line to help clear Miles.

As the case comes dangerously close to unraveling, Sammy must stitch the clues together. But the killer has other plans - and if she’s not careful, she may wind up in a perilous knot.
