dialogue: Susan: Hello William!  I forgot to ask you yesterday: I've been trying to track down this biography of Droste by Karschunov. They don't seem to have a copy at the college library and I don't fancy buying it. Could I borrow it from you?
  William: Hello Susan, but I'm not sure I have it. What's the title?
  Susan: "Das Spiegelbild"
  William: Rings a bell. Let me check and I'll get back to you, Susan.
  Susan: Thank you William.
  William: Yes, I have a copy. A bit bashed but readable :) If it's urgent, I can send it to you.
  Susan: Great that you have it. No, it isn't urgent at all. Droste is just on my list and I'll tackle her in due time. I just have to remember about the book before we meet next time.
  William: Isn't it pretty soon? Hasn't Rita arranged for some meal together these days?
  Susan: True! St Martin's Goose on the 10th! It is this coming Friday. Will you be as kind and bring the book with you?
  William: But of course! Pleasure.
  William: And you can keep it. I don't  think I'll be reading it again.
  Susan: Thank you! Lucky me. So see you and Rita on Friday.
  William: Looking forward to. Give my regards to Harry please.
  Susan: I will. Thank you.
summary: Susan will borrow "Das Spiegelbild" book from William. William will bring the book to their meeting together with Rita on Friday 10th. Susan will pass regards to Harry from William.
