Friend or foe

There was nothing threatening or frightening about them, they were just two exhausted, pale-looking men with sad eyes and kind faces. These were the men who had bombed London and Plymouth and killed thousands. Yet one of them had saved his life. It's the Second World War, and the Germans are bombing London. Everyone hates them, especially David: they killed his father. Now because of the Blitz, David and his friend Tucky have been evacuated to the countryside, where they must live with strangers. Then one night they see a German plane crash on the moors. They feel they should hate the airmen inside, but can they just leave them to die?
