M: It’s all right Mary, where have you been?

M: Where?
W: At the police station. I’ve lost my briefcase.
M: Oh no, what happened? Was there anything important in it?
W: Yes, my checkbook, all the papers I need for work. My appointment book.
M: Oh that’s terrible. How did you lose your briefcase?
W: Well, as you know, I was with my client at a meeting all morning and we had lunch together. After lunch, I went shopping and when I wanted to buy something I couldn’t find my checkbook. Then I remembered that it was in my briefcase and my briefcase was in my car.
M: So you went back to your car?
W: Yes, I went back to my car, no briefcase, but luckily my laptop was there.
M: And then you went to the police?
W: Not immediately before I went to the police station. I called my client’s office. No luck. They said the briefcase wasn’t there.
M: Excuse me. I’ve got phone call. Yes, yes, there is. Mary Hopkins. Oh, really? I’ll tell her. It was very kind of you to call. Bye.
W: Who was that?
M: That was the manager of the riverside restaurant just after lunch today. He found a briefcase under a table. When he opened the case, he found a lot of papers. He said they had the name of our company on them, and he found a checkbook with the name of Hopkins on it. M Hopkins M for Mary.
