Dot and Anton

He has to earn money and help his mother do chores all while also going to school in order to make ends meet.

Dot lives in a large apartment with her little brown Dachshund Piefke, the cook Berta (known as Fat Berta), the governess Miss Andacht and her parents: Fritz Pogge the walking-stick factory director and his wife, who both barely spend any time with her.

In spite of Anton and Dot being from different backgrounds, they become close friends and spend a lot of time together.

She notifies the police but the burglar arrives before them and is knocked unconscious by Berta with a club upon entering the apartment.

The governess then flees and the Pogge family returns home where they not only meet the housekeeper but also the police and the arrested burglar, who Dot identifies as Miss Andacht's fiancé.
