Max Mallowan: Do I know you?

Agatha Christie: No, we've never met.

Max Mallowan: I'm sure we have.

Agatha Christie: Well, sometimes people think they've met me. It's an unfortunate consequence of being a bit famous.

Max Mallowan: [impressed] You're famous? Let me guess... You're the wife of a well-known politician?

Agatha Christie: [unimpressed] No. I'm not famous by marriage.

Max Mallowan: You're a well-known home-economist. Like Mrs. Beeton?

Agatha Christie: No, I'm not famous for my practical housekeeping.

Max Mallowan: I've got it. You're an actress!

[Agatha laughs]

Max Mallowan: . Retired of course...

Agatha Christie: [offended] My name is Agatha Christie. I'm a writer.

Max Mallowan: No, sorry. Never heard of you.
