 Sergeant Craddock attends dancing classes to keep up his dancing skills. He also has something of a soft spot for the dancing teacher Susan Finlay. That friendship is put to the test when her son Richard drives through Aidensfield like a regular Jackie Stewart and refuses to stop when the police want to give him a speeding ticket. Craddock lets him off with a warning, but the following night a little boy is run down by a hit-and-run driver, who may very well be Richard driving in her car. Lord Ashfordly is forced off the road by Richard s reckless driving. The petrol tank of his Bentley gets punctured in the incident and he takes it to Bernie s garage. But Bernie is out of town for a few days and Vernon becomes an instant expert on Bentleys when his lordship needs his car back badly.
