Joanne had planned to leave work early this afternoon and have a bath before going out to a meeting

When she arrived at her house，she noticed something strange about Sheba，a large dog．Sheba was lying on the floor and could hardly breathe（呼吸）．Joanne realized she would have to take her to the vet immediately．

“It looks like something is stuck in her throat，" said Dr．Sterne，"it shouldn't take me too long to get it out．"

As she was going to a meeting，Joanne left the doctor with the dog and rushed back home．When she was once more entering the house，the phone rang．Dr．Sterne's anxious voice was heard，"I want you to get right out of your house immediately，" said the doctor．"The police will be there any time now．Wait outside for us．" Joanne was confused and frightened（吓坏的），She quickly ran into the street．

At that moment，a police car stopped outside the house．Two policemen got out and ran into the house，without explaining anything．Then the doctor arrived．Just then，the two policemen came out of the house，carrying a man，who，it seemed，could hardly walk．There was blood（血） all over him．

"I think he must be a thief，" said the doctor．"I knew he was there because I finally took three human fingers out of Sheba's throat．"
