- John Steed: As I've demonstrated, Mrs. Peel, our mysterious intruder must have come in through the front gate.
- Emma Peel: Across the entrance hall...
- John Steed: Past three checkpoints...
- Emma Peel: Came down the security lift...
- John Steed: Across the main hall...
- Emma Peel: The Typing pool...
- John Steed: Passed a dozen clerks...
- Emma Peel: Ah, and don't forget the four secretaries, Steed.
- John Steed: Hmmm. Indeed not.
- Prof. Ernest Quilby: You a member? Of the B.A.?
- John Steed: The B, eh...

- Elena Vazin: You have heard of a man called John Steed?
- Ambassador Brodny: Oh yes. Yes, I have known him for years. The man of many talents. Of excelent taste, a good frie - a sworn enemy!
- Elena Vazin: You are very foolish, Mrs. Peel. You cannot escape from here.
- Emma Peel: No? It's been child's play so far. Such stringent precautions. No guards in reception, Brodney with an empty gun...
- Elena Vazin: The fool. He will pay for that.
- Emma Peel: But you gave it to him. If I'm wrong, do forgive me.
- [points the gun at Elena and pulls the trigger several times]
