- [SPOILER]
- Nicholas 'Nick' Mullen: [angrily] Where'd the tip-off come from?
- Harry Champion: Look, you know perfectly well I've got to protect my sources.
- Nicholas 'Nick' Mullen: Oh yeah? Well, from now on, nobody is protecting anybody.
- Harry Champion: I'm sorry, I can't tell you.
- Nicholas 'Nick' Mullen: I want to know who told you Kleist was KGB.
- Harry Champion: I can't tell you!
- Nicholas 'Nick' Mullen: It was the same source rang me up and gave me the Prague story, wasn't it?
- Harry Champion: I've no idea.
- Nicholas 'Nick' Mullen: [chuckles] Come on, Harry. Who was it?
- Harry Champion: Look, he's in the Security Services. He's very, very high up. I used him for fifteen years and he's never been wrong. That's all I can tell you.
- Nicholas 'Nick' Mullen: Yeah? Well, you better get yourself a new contact, Harry.
- Harry Champion: Really.
- Nicholas 'Nick' Mullen: Yeah. Kleist is no more KGB than Kim Philby was MI6. He's a British agent.
- Harry Champion: [laughs incredulously] Oh, that's very good. Now, where did you get that from, John le Carré?
- Nicholas 'Nick' Mullen: No. I got it from George Rydell. In black and white. Now, I want a name.
