Was there anything important in it? W: Yes! My cheque book, all the papers I need for work, my appointment book (Q8). M: Ah! That's terrible! How did you lose your briefcase? W: Well, as you know, I was with my client at a meeting all morning (Q9) and we had lunch together, after lunch I went shopping, and when I wanted to buy something I couldn't find my cheque book, then I remembered that 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 (Q8). 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 a 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 River Sun 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 cheque book with the name of Hopkins on it— M. Hopkins—M for Mary (Q10). W: Ah! Thank god! What is NOT missing in Mary's briefcase?
