What is NOT missing in Mary’s briefcase?

W: Sorry, I’m late, James.
M: It’s all right, Mary. Where have you been?
W: At the police station.
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 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!
