Carrie Kennersly, veterinary technician and owner of the Barkery and Biscuits bake shop, agrees to a day of hiking with her brother Neal mostly because she wants to meet and critique his latest romantic interest, Janelle Blaystone. But instead of judging her, Carrie feels only sympathy for Janelle, whose beloved black Labrador, Go, was recently dognapped. Janelle thinks the culprit is Ada Arnist, a wealthy homeowner spotted at the dog park where Go was stolen. Soon after Janelle confronts Ada, though, the woman is found dead. With Janelle and Neal on the suspect list, Carrie must solve the mystery before the police bark up the wrong tree.
