Police officers in Tayside discuss working in such a vast yet sparsely populated area, where traffic accidents are the main concern. Former Glasgow PC Ronnie Deuchar reveals how his first week in Pitlochry was so quiet he suspected his radio was broken, and as Sergeant John Watson approaches retirement, his colleagues explain how he can walk into a pub and sort out a situation just with a look. PC Peter Lorrain-Smith explains his belief that the best way to fight crime is to get youngsters on the straight-and-narrow early. Last in the series.
