Karnie works in her family's butcher shop. When Donna Amick stalks to the meat display case and tries to pressure her to leave the family business to work for her, Karnie turns her down, flat. But Donna doesn't like to take "no" for an answer. The next morning, Donna's body is found behind A Cut Above with a meat cleaver embedded in the back of her head. Detective Carmichael's top suspect is Sam Lessman, who trained at their shop and then went to work for Donna as a full time butcher. Karnie knows it can't be him and decides to prove it. Unfortunately, that's a lot harder to do in real life than it is in the mysteries she reads.
