Now living in their new home in the country, without their father, the children befriend Perks at the local railway station and go ‘coalmining' at the station stores.

Mother is taken ill and the children get a message of help to a kindly old gentleman on the train, who sends her a hamper.

Mother and the children come to the aid of a distressed Russian gentleman who arrives at the station and Bobbie learns the truth about her father.
