THE GIRL ON THE MOTORBIKE
In the early hours of November the 1-st, 1999, a motorbike was speeding along the A20 in Kent. The night was dark and there was very little traffic on the road. Clivc Taylor was in a hurry to get home. He had been to a party and left London later than he had expected.
As he approached Wrotham Hill, he glanced at his watch. Exactly two o'clock. He changed gear and sped up the hill A minute later he reached the top of the hill. It was a dangerous place for accidents. But with so little traffic on the road, Clive didn't slow down.
Suddenly, he saw a girl She was standing in the middle of the road. Clive had to swerve to avoid knocking her down. But she didn't move. When he had stopped, the girl calmly walked up to him and asked him if he could give her a lift. He asked her what she was doing in such a lonely spot. She said that there had been an accident. Clive looked around, but he couldn't see a car or any other people. He asked the girl what had happened, but she didn't reply.
Clive told her to get on the motorbike and to hold tight. As the girl climbed on, Clive suddenly felt very cold, but he noticed that she was only wearing a light dress. She looked as if she were on her way to a party.
They rode on down the hill and Clive talked to the girl over his shoulder. He asked her what her name was and where she lived. But she didn't reply. At one point Clive thought that she shouted something, but he couldn't hear very well over the noise of the motorbike's engine.
At the bottom of the hill there was a telephone box. Clive pulled off the road and stopped.
But when he turned round, he froze in horror. The girl wasn't there. He called out, but there was no sign of her.
Then Clive remembered the shout that he had heard. Had the girl fallen off the motorbike? In cold sweat, he rode back up to the spot where he had first seen the girl. But he couldn't see her. He rode down the hill again as slowly as he could. There was no sign of her. She had simply disappeared.
By this time, Clive was desperate. He rode as fast as he could to the nearest town and found the police station. He told the sergeant in charge what had happened. The sergeant asked him to describe the girl. When he had finished, the sergeant told him to sit down and asked him if he wanted a cup of tea. To his surprise, the sergeant didn't seem very worried.
Then the sergeant told Clive that ten years before, there had been an accident on Wrotham Hill.
