Some years ago an American policeman found[19]a woman lying near a lonely road. She didn’t appear to have had an accident but she was trembling and clearly in a state of shock, so he rushed her to the nearest hospital. She began to tell the doctor on duty the story which was astonishing in all respects. She had been driving along a country road when she had been stopped by a flying saucer landing in front of her.[20]She had been forced to leave the car and entered the flying saucer by creatures which looked like human beings and which had easily made themselves understood though they couldn’t speak. It was as though they could read her thoughts and she could read theirs. They treated her politely and allowed her to leave after carrying out a number of tests on her. As she otherwise seemed to be normal, the doctor decided that she was probably suffering from the side effects of some drug.[21]The woman insisted on being allowed to go home, but when she gave her address it was a town over a thousand miles from the hospital. The police then started to make inquiries and soon discovered that there was already a search going on for the woman, whose husband had reported her missing. Her car had been found with the driver’s door open and the engine running.
