Late one evening, a man and a his wife were driving their car at speed down a country road. The car spun of the road and hit a tree. The man decided to seek help at a garage a few miles away.
He made sure that all the windows were wound up and locked all the doors.
When he returned, his wife was dead, and there was someone in the car he had never seen before. No physical damage was done to the car and it was still locked. How did the woman die? Where did the stranger come from?
