Ash and Scribbs investigate the death of Christine Archer, a kennel owner and dog walker who was killed in the woods. In doing so, they enter the strange world of dog owners and their pets with several of the former having a motive to kill her. They meet Malcolm Eysher, who has recently broken an affair with the dead woman, and his somewhat ditsy wife Fiona who, it turns out, knew what he was up to. Then there is her business partner, Steve, who was cheating her by taking clients on the side. Finally, there is William Marshall against whom Archer had filed a complaint of owning a vicious dog. With her death, he is set free. Scribbs realizes that a final photo taken by the victim with her camera phone provides the necessary clue to solve the crime.
