    "My dear lady," says Holmes. "You're shivering. Are you cold? Do you want a cup of hot tea?"

    "I'm not cold," the woman replies, "I fear for my life!"

    "We are here to help you. Don't worry about anything. I don't know you. But I know many things about you. For example, I know how you travel. You came to London by train. You also ride to the train station on a horse-drawn wagon(马车)."

    "Why, yes. You're right. But how do you know these things?"

    "I see a return ticket in your glove. I see fresh mud on the left arm of your dress. Now tell us your problem."

    "My name is Helen Stoner," she states, "My mother and father are dead. I am living with my stepfather, Dr Grimesby Roylott. He comes from a rich family. But they are no longer rich. They have nothing except a small piece of land and a huge old house. We are living in the house. Dr Roylott is using my mother's money for expenses(开支). Part of it was for my sister and me. It was for our marriages."

    Holmes is sitting in his chair. His eyes are closed. He is listening carefully to Helen's story. He hears every detail(细节).

    Helen continues. "My stepfather has no friends. He fights with everyone. He is strong and gets angry quickly. Everyone is afraid of him."

    "He has no friends at all?" asks Holmes.

    "No. He talks to no one except the gypsies. They are poor people who travel from place to place. A band of gypsies is staying on our land right now."

    "Are you and your sister afraid of the gypsies?"

    "My dear Mr Holmes. You are making me so sad. My sister is dead. That is why I am standing here in this room."

    It was a beautiful spring morning. There wasn't a cloud in the sky, and the sun was warm but not too hot, so Mr Hunt was surprised(惊讶) when he saw an old man at the bus stop with a big, strong black umbrella ( 雨伞) in his hand.

    Mr Hunt said to him, "Do you think it is going to rain today？""No，" said the old man, "I don't think so."

    "Then are you carrying the umbrella to keep the sun off you？"

    "No, the sun is not very hot in spring."

    Mr Hunt looked at the big umbrella again, and the man said, "I am an old man, and my legs are not very strong, so I really need a walking stick. But when I carry a walking stick, people will say 'Look at that poor old man. 'and I don't like that. When I carry an umbrella in fine weather, people only say，'Look at that stupid(愚蠢的) man."

    One day, a man saw an old lady sitting inside her car at the side of the road. Though it was dark, he could see she needed help. So he stopped his car and walked towards her. The old lady was worried, even though she noticed the smile on his face. Was he going to hurt her? "I'll help you start your car, madam. By the way, my name is Bryan Anderson, " he said.

    While Anderson was fitting a spare tired (备胎) to her car, the lady began to talk to him. She thanked him much for coming to help.

    Anderson just smiled as he put his tools away. The lady asked how much she should pay him. He told her that if she really wanted to pay him back, the next time she saw someone who needed help, she could give them the help they needed. He waited until she started her car and drove off.

    A few miles down the road, the lady saw a small restaurant. She went in and a waitress came over with a sweet smile. The old lady noticed the waitress was nearly eight months pregnant (怀孕的), but she never let the pains and aches change her smile when she served her.

    The lady finished her meal and paid with a hundred-dollar bill. The waitress quickly went to get change, but the old lady was gone when the waitress came back. The waitress wondered where the lady could be. Then she found there was a note on the napkin (餐巾), "You don't need to give me anything back. Somebody once helped me out the way I'm helping you. If you really want to pay me back, here is what you do—do not let this chain (链子) of love end with you."

    Under the napkin were four more $100 bills.

    Miss Grey lived in a small house. She was old and did not like noise at all, so she was very pleased when her noisy neighbor moved out. A young man moved in and Miss Grey thought the man seemed to be quiet.

    But at three o'clock the next morning, the noise of a dog woke her up. She thought she had never heard a dog there before. It must be the young man's dog. So she telephoned the young man, said something bad about the dog and then hung up the telephone before he could answer. Nothing more happened until three o'clock the next morning. Then Miss Grey's telephone rang, and when she answered, a voice said, "You telephoned me twenty-four hours ago, now I ring you up to say that I don't have a dog."

    It was a Christmas night. I was an unlucky nurse who had to work on such a beautiful festival. When I was complaining(抱怨)about it, three people appeared at my desk — a tired woman and two children.

     "Are you all sick?" I asked doubtfully because they seemed all right.

    "Yes," the woman answered weakly and lowered her head.

    But when they started to present their problems, things became unclear. One child had a fever, but his temperature was OK. The other child had an earache, but she could not tell me which ear hurt. It seemed that the mother was pretending(假装)to cough.

    Something was wrong. But I only explained that it might take a while before a doctor could meet them. "Take your time, please," said the mother. I checked their charts — no address. Suddenly I knew, they were homeless while the hospital was warm.

    The family huddled(蜷缩)together under the Christmas tree, smiling and talking with each other sweetly. Quietly, I went back to the nurses' station and told them what happened in the waiting room. It was just like God sending us a gift on Christmas Day. The nurses' station suddenly came back to life. All the nurses went into action for "a Christmas emergency(急诊)".

    We took out our meals for our Christmas "patients". We also put together oranges and apples as presents. We tried to exceed the needs of a family who only wanted a warm place on Christmas night. Later, the little girl kissed me and said, "Thanks for being our angel(天使)."
