When Maggie Messina, owner of the Black Sheep Knitting Shop, is invited to give knitting workshops at a Berkshires spa resort, she manages to negotiate a cottage that fits all five of the Black Sheep for a weekend of knitting bliss. The owner of the Crystal Lake Inn is charismatic self-help guru and former psychiatrist Max Flemming. The doctor may have told all in his autobiography, but he seems mired in shadows from his past. And when a killer strikes at a mountaintop retreat, the Black Sheep wonder what the doctor might be hiding.
