What did Annmarie learn about Peter from Uncle Henrik?

Annemarie learns that Peter works with the Resistance to smuggle Jews out of the country.

Peter, and others in the Resistance who work with him , bring them to me, and to the other fishermen as well. There are people who hide them and help them , along the way to Gilleleje."

Annemarie was startled. "Peter is in the Resistance? Of course! I should have known! He brings Mama and Papa the secret newspaper, De Fret Danske. And he always seems to be on the move. I should have figured it out myself!"
