Det. Supt. Sandra Pullman: Nine-o-two p.m. seventh of February 2004. This is the seven p.m. train from Charing Cross to Dover and it's two hours into its journey.
Brian Lane: Two hours? Shouldn't they be in Dover by now?
Det. Supt. Sandra Pullman: Yeah, it should be, but a couple of miles out of the station someone pulled the emergency handle. Now watch this.
Det. Supt. Sandra Pullman: [showing train security video] Four seconds. It takes four seconds to go through that first door, along the short connecting corridor and then into the buffet-car. Four seconds. This guy here is Doctor Philip Mackenna; he's a physics professor at University College London. He was due to catch the ferry from Dover to Calais and then another train to Paris, where he was going to speak at a conference on theoretical physics the following evening. Now keep watching. He talks to the blind man; then he gets up, and he heads to the buffet-car. Four seconds.
Det. Supt. Sandra Pullman: Doesn't matter how long you wait. Philip Mackenna never comes through that door and he hasn't been seen since.
Martin Fallon: All this is down to you. If you hadn't put in a good word for me in court...
Jack Halford: You were never malicious, Martin. Just stupid.
Martin Fallon: That's very kind of you to say so.
D.A.C. Strickland: So what was the point of all this?
Stephen Fisher: This is the intelligence community, Robert. You start worrying about the point of it all, you'll end up tying yourself in all sorts of knots.
Brian Lane: Well, as Gerry says, good luck tracking down Alice Fox.
Gerry Standing: On the other hand, she might be hiding in the pub!
D.A.C. Strickland: Oh. I'll get the first round in.
Brian Lane: Bloody hell!
D.A.C. Strickland: Yeah, well, don't get used to it.
Det. Supt. Sandra Pullman: Don't think there's any danger of that, sir.
