Der Engel, der seine Harfe versetzte.

One day, an exceptionally beautiful girl shows up at Josua Webmann’s pawnshop to pawn a golden harp. Josua’s apprentice, Klaas, immediately sees her as an angel. That evening, she meets him again and dances with him, causing even the previously indifferent Lissy to take notice of Klaas. Meanwhile, Josua worries about his money and negotiates with an instrument dealer who makes him a generous offer for the harp. The next day, the girl and the harp have disappeared again—but she has left behind unexpected wealth.
