　Just at that time a police car did overtake. The two officers (警官)inside looked at us seriously when they went past . But then , with a kind smile they asked us to follow their car through the busy traffic. The police car stopped at our village church (教堂) . One of the offices came to me.
　"Right, sir, " he said. "Do you need any more help now?"
　I didn't quite understand . "Thanks, officer, " I said . "You've been very kind. I lived just down the road. "
　He was looking at our things: first at the flowers, then at the bookshelf. "Well, Well, " he said and laughed . "It's a bookshelf you've got there ! We thought it was-err, something else . "
