     Dr Zhang worked in Gulou Hospital. He had to stay late at the hospital one night to do an operation.

 He finally left at about 11 pm. He drove home slowly because the weather was terrible - the wind was

  strong and it was raining heavily. He was turning into the road when a man suddenly ran in front of his car.

  He almost hit him but the car stopped just in time. He was frightened and the man looked frightened, too. 

  Dr Zhang got out of the car to see whether the man was OK. But the man ran away before Dr Zhang

 could say anything. Dr Zhang felt it was very strange.

     When he got home, the lights were on. He called to his wife but there was no answer. Then he

 remembered that she was at a concert in Nanjing Olympic Centre.

     He was still very upset about what happened on the road. So he made himself a drink. Then he went up

 stairs to have a bath. He saw that the window in the bedroom was open. This was strange because his

 wife always locked the doors and windows before she went out. She was afraid of thieves. When he went

  to close it, he found his wife was lying on the floor. There was blood everywhere. He hurried to her and

 found her dead. He sat beside her body and was too frightened to do anything.

     He phoned the police in the morning. They came half an hour later. Dr Zhang tried hard to remember

 anything he could. He couldn't stop thinking about the man on the road. What was he doing at that time
