The lady lives with her stepson Axel, his wife Gudrun and his daughter Beate, whom she would like to leave her possessions, including a part of her family estate in France. But the girl disappeared since months and Mrs. Richarz's conditions are that in absence of Beate her possessions would go to her siblings in France.
