A few years later, the Baron and Franz are in the same air squadron, and Franz, at first, refuses to fly because of a full moon. When he does and crashes, the Baron sees a wolf at the controls.....and seconds later is shot down. Many years later, the Heap is drawn to Hungary and seeks out the Count's son, and later destroying him.
