It all started as a great Halloween party in the house of her old friend Jenny who lived in Scotland. One day Jenny thought that it would be a great idea to organize a real Halloween party and invite all her classmates. Betty was Jenny's best friend, but at first she was not sure about this party. Betty did not want to see Derek, her ex-boyfriend who has been the soul of their gang at school. So Jenny promised not to invite him and Betty agreed to come. The party was lovely. A lot of people came from different parts of the world. It was interesting to find out that Simon had moved to France and Gregory and Kate had got married and left England for Italy. Betty was having a great time when she looked out of the window and saw Derek. He was getting out of his cool sports car. He had not changed at all and looked as handsome as he done at school. Betty had no time to fall out with Jenny — she tiptoed out of the living room and ran to her car. An hour later she still was driving through some rather wild countryside. She was so angry that she had forgotten to take her map, and she did not know where she was. It was getting dark, it was raining and a cold wind was blowing. Betty's car was rannig out of petrol. Her best friend had let her down. Betty was scared and tired. She understood that she had been lost. Suddenly she saw a light in the darkness and in a minute Betty stopped in front of a little hotel. Next to the hotel there was a very old graveyard with a small church. "This is exactly what one needs on Halloween night. I'm sure the owner of this hotel is going to tell me that it has belonged to a family of vampires for the last eight hundred years," Betty thought to herself as she was looking around. At that moment the door opened and a tall old man came into the light. "The night is cold and wet," he said to Betty and smiled. "Do come in." As Betty walked in, she was greeted with a warm smile by the hostess. The woman had understood everything immediately. "What would you like to eat?" she asked. "We've got a fish pie or lamb chops for dinner." Betty did not mind and in a minute the old man was laying the table and his wife was warming up some food. "Don't worry, darling," the old woman said. "You won't have to eai your dinner alone. Our grandson Derek will be back any minute. He is spending this week with us. This afternoon his classmate Peter phoned and told him about some party which was just round the corner. Our Derek went just to say hello to his old friends, but he won't be long. He is such a lovely young man, our Derek. I'm sure you will like him."
