      One summer afternoon Jane and James Brown visited their daughter at her home in Lily, France. A few
minutes before six, the Browns decided to leave. They said goodbye to their daughter, walked to their car and
got in. Mr. Brown was about to start the car when a gunman (持枪歹徒) jumped up from the back seat. He
held a gun to Mr. Brown's head. "Drive me to Paris!" he ordered. "All right," Mr. Brown answered. "I'll drive
you anywhere you want to go. But first let my wife out of the car."
      The gunman agreed. After she was safely out of the car, Mr. Brown started the engine and drove down
the street. He was driving slowly but his mind was racing. Unarmed and 81 years old, he knew he could not
fight the gunman. Suddenly Mr. Brown realized how he could attract the attention of the police. He began
driving like a mad (疯) man. He drove sixty miles an hour on side streets, ran red lights, and drove the wrong
way on one-way streets. But not one police officer saw him. Suddenly he remembered that the Lily police
station was only a few blocks away. "All right," he thought. "If I can't bring the police to my car, I"ll bring
my car to the police."
       He turned corner and saw the police station ahead. The two large doors were closed. He sped up (加速)
the car straight for the doors. The car crashed through the doors and stopped in the courtyard. Mr. Brown
cried, "Help! He is going to kill me." It happened so quickly that the gunman didn't know what to do. Just then
the officers from the police station had already come. They quickly caught the gunman. It was 6:30 p.m.; only
35 minutes after the Browns had left their daughter"s home on a quite street in Lilly.
