In The Silver Sword by Ian Serraillier, the children are separated from their mother, Margrit, when she is forcibly taken by Nazis to work in Germany. One of the children shot at the soldiers that were taking her away, and as a result, the Nazi's burnt down the family's house. When Joseph, the father, returns home after escaping from a German camp, a woman who lives nearby tells him what had happened. He believes that Margrit will be able to get to Switzerland, her home country, if she can escape the Germans. At the end of The Silver Sword, Margrit is reunited with her children in Switzerland, indicating that Joseph was correct in this belief, although it is never disclosed when during the course of the war she made her escape or how she got to Switzerland.
