Skeldale House descends into chaos with the arrival of Siegfried's wayward brother Tristan. Helen provides James with a reason to stay in the Dales.

James is forced to take in Mrs Pumphrey's pampered Pekingese. Tristan prepares to return to university, but needs Siegfried's help to pay for his accommodation, but Siegfried insists he must first prove he is serious about being a vet. James treats the Aldersons' prize bull, and Helen rewards his efforts with some unusual home baking.
