- Carmen Joyce: Quinn is dead?
- Adam Carter: Dogfish ate half his face away. Apparently there's a lot of dogfish in the North Sea.
- Oliver Mace: There's a serious threat to national security here. I can't keep to the niceties.
- Harry Pearce: I like the niceties. They protect us from tyranny.
- Harry Pearce: So we lure a United States citizen to this country and force confession out of her? That is a totally illegal, madcap scheme. I like it. Great idea, Adam.
- Adam Carter: It's not mine, it's Tom's.
- Ruth Evershed: Uh, we had a spook taxi outside the hotel. Carmen hired it.
- Harry Pearce: Spook taxi?
- Ruth Evershed: Yeah I, I, I've been recruiting taxi drivers. It's cheaper than having our own cars.
- Ruth Evershed: Excuse me, can I talk to you?
- Nurse: Sorry?
- Ruth Evershed: It's about Mr. Pearce.
- Nurse: They're saying he's a spy?
- Ruth Evershed: He is, and the, the thing is, I work for him, and I'm in love with him, and they won't let me see him. Could you give him a note?
- Nurse: I don't think so.
- Ruth Evershed: I mean, I'll write it.
- Nurse: No, sorry.
- Ruth Evershed: I'm having his child.
- Tom Quinn: Who the hell do you think you are?
- Adam Carter: Actually, mate, I'm an officer who didn't get suckered by an American con artist.
- Oliver Mace: Ah Harry, good to see you. Do you know Jason Belling?
- Harry Pearce: Only from certain tape recordings.
- Danny Hunter: Tom. Not dead, I see.
- Tom Quinn: No, I'm not dead. I feel pretty dead inside, but we don't wanna go there, do we?
- Christine Dale: It nearly destroyed me. It is destroying you.
- Tom Quinn: No, I'm fine. Dandy. Cock-a-hoop.
- Herman Joyce: So, what are you gonna do? Take me in?
- Tom Quinn: Yeah, that's the idea.
- Herman Joyce: You remember my CV, who I am? I spent a year in Lubyanka, a prisoner of the KGB. You think English gents in MI-5 are gonna get me to confess with a few sleepless nights and psychological games? Hell, they'd have to burn my genitals off with red-hot metal. And even then, I probably won't tell them how I set you up.
- Adam Carter: How did you set up an operation like that?
- Carmen Joyce: It was financed out of Damascus.
- Adam Carter: Fun town.
- Zoe Reynolds: We're going round and round in circles. He shot Harry!
- Danny Hunter: Yeah, but he was facing arrest for treason with zero chance of proving his innocence. He had to escape. I mean, if it had been me, I'd have pulled the trigger.
- [Zoe stares at him]
- Adam Carter: What about you, Harry. If you'd been in Tom's position, would you have shot you?
- [last lines]
- Harry Pearce: You went over to them.
- Oliver Mace: Yes.
- Harry Pearce: Damn near landed us with a Ministry of Security running a secret police.
- Oliver Mace: I was, perhaps, somewhat blinded by ambition.
- Harry Pearce: Somewhat blinded?
- Oliver Mace: You can't force my resignation, you know. This is only a one-all draw.
- Harry Pearce: James, same again for Mr. Mace and I'll have a large usual, not on my tab.
- James: Thank you, Mr. Pearce.
