- Sgt. O'Hare: Mrs Carstairs, the Lieutenant here is a great admirer of your books.
- Dinah Carstairs: Oh really, which one did you like best Lieutenant?
- Lt. Bill Smith: [discomfited] Er...... ..latest one, Mrs Carstairs. I thought it was excellent.
- Dinah Carstairs: Oh, so you liked the Maltese Falcon?
- Lt. Bill Smith: Yes, yes, that's the one.
- Dinah Carstairs: Lieutenant, that was written by Dashiell Hammet, about twelve years ago. I don't think you've ever read any of my books.
- Lt. Bill Smith: [sheepish] I'm afraid you're right.
- Sgt. O'Hare: Not being a married man, Mrs Carstairs, the Lieutenant ain't a very convincing liar!
