Graeme Hall's first case takes him to the Midlands, where a mischievous Jack Russell is causing trouble in a special bond between a young girl and her grandfather. Every time 10-year-old Darcy visits, Milo can't seem to leave her side. Graeme also returns to help Carol and Peter, whose two puppy sisters were once at odds. Although Graeme had previously helped them start to get along, new issues have now emerged.
