“I’m afraid so.I’m in a big hurry and I can’t start my car.”
“Is there something I can do to help？” Arthur asked.The_young_man looked at the two suitcases in the_back seat and then said，“Thanks.If you’re sure it wouldn’t be too much trouble，you could help me get these suitcases into a taxi.”
“No trouble at all.I’d be glad to help.”

Park Avenue had been quiet a moment before.Now the air was filled with the sound of the alarm and the_shouts of people running from all directions.Cars stopped and the passengers joined the crowd in front of the bank.People asked each other，“What happened？” But everyone had a different answer.
Arthur，still carrying the suitcase，turned to look at the bank and walked right into the young woman in front of him.
She looked at the suitcase and then at him.Arthur was surprised. “Why is she looking at me like that？” He thought.“The suitcase! She thinks I’m the bank_thief！”
