Fall has come to Fort Connor, Colorado, and the cool air has inspired the knitters at the House of Lambspun to start on their hats and mittens. It's also brought an influx of students to the university town--and into the shop for knitting classes. Kelly Flynn is happy to teach them the tricks of the trade-until one of them is found dead on the river trail near Kelly's house. Compelled to investigate, Kelly finds herself following a path that twists more easily than the yarn with which she knits. Knowing the killer could be close, Kelly must work fast to unravel the skein of this crime.
