3: Losing Hope

The search for Tony Parsons is extensive. It's painstaking. And it's fruitless. But there are signs that they're inching closer to finding out what happened, and where he is.
Officers discover a last sighting, and use CCTV to narrow down Tony's progress. Do the answers lay in a small stretch of the Highland route, which police have already searched?
