Inspired by Bruno, Jack Ryan challenges old Hermann Heinz to a "best of three" race up the steepest road in the district, between his Model T Ford and Hermann's trusty horse and sulky.

The annual beach picnic is approaching and Mum is knitting new bathing costumes for all the children. Bruno complains that he can't possibly wear his because everyone will laugh at him.

To everyone's great surprise, dad has bought a car. Bruno and his sisters are ecstatic. The family's first outing is a tin-kettling party for a local couple who are to be married.

When Bruno goes on his rabbit trapping rounds, he meets up with a wild-looking hermit, Ebenezer Blitz, and his wolf-like dog. But for the moment he forgets the encounter as his family runs into a series of troubles.

Keeping to himself his fear that Ebenezer's dog might be the turkey killer, Bruno joins in the community hunt to find the suspected fox, which has savaged one of Mr Mibus' prize rams.
