Schoolteacher Barry Jackson's wife Sophie is very ill and not capable of driving a car because of it. Nevertheless she takes the car one day and causes a bit of mayhem in Aidensfield. Soon afterwards Jackson receives threatening letters, and during a school concert somebody sets his house on fire killing Sophie. Malcolm Brown checks into the Aidensfield Arms with his daughter Vicki, but Gina suspects that that something is wrong with them. Apart from that there is an extra resident at the pub - a carrier pigeon, and Gina soon discovers it is very fast bird indeed and they challenge Greengrass to a pigeon race.

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.
