Yarn shop owner Kath Rutledge is looking forward to the grand opening of a new co-op of small shops, but in the week before the grand opening, two of the shopkeepers, Nervie and Belinda, begin a venomous feud. Despite the rivalry and an act of vandalism, the opening is a success—until Belinda is found dead, stabbed in the back with a pair of scissors from Kath's shop. Geneva, the ghost who haunts Kath's store, claims she saw the murderer leaving the scene of the crime. But the ghost is the ultimate unreliable witness—only Kath can see or hear her. Following book five, Knot the Usual Suspects, it's up to Kath to solve the crime before the killer cuts another life short.
