Ben and his wife Susan were on their way to have dinner with their friends. It was a dark,windy night, and they did not know the way very well. They drove through a town until they found what they thought was the road to Dorling,where their friends lived. But it soon became clear that they were not on the road to Dorling at all. The road that they were on was getting narrower,and there were no other cars on it. The wind was blowing harder with every minute that passed.

They came to a small village .They drove past a church and then two houses without lights on. There was nobody about to tell them where they were,or where the road went. Just then,Ben saw a telephone box,twenty meters or so further on.
