Lise was hit by a car and passed away. This occurred two weeks before her own wedding. This was also the year the Nazis occupied Germany.
This is mentioned in the novel because Kirsti thought she heard 'fireworks' on her birthday.
The Danish Jews were warned by their Rabbi that the Nazis will be coming to relocate them. In the novel, this is what happened to the Rosen family, and when Ellen stayed with the Johansen family.
The soldiers came looking for the Rosen family at 4:00am.
In the morning, Annemarie, Ellen, Kirsti, and Mrs. Johansen get on a train to go to Uncle Henrik's house.
It's Great-Aunt Birte's funeral, and there are people arriving. These people are soon to be smuggled on Uncle Henrik's boat. Annemarie will soon be having to run to the boat to deliver the package.
