- Uniformed official: It was very good of you to return after your predecessor...
- Christopher Foyle: Died!
- Uniformed official: In very unfortunate circumstances.
- Christopher Foyle: It's my experience that most death is unfortunate, but all that was some while ago.
- Police Sergeant: [tO fOYLE] You can't have a shoot-out in a civilian population. It's like the Wild West!
- Monsieur Duveen: [after being questioned by Foyle about the two Russians] Neither of these men were here.
- Christopher Foyle: You're quite sure of that?
- Monsieur Duveen: Have we given you any reason to doubt us?
- Christopher Foyle: Since you mention it, Vladchenko had nowhere else to go in London. Spiakov told him specifically to come here, and it would be interesting to know, uh, since you've no idea where I've come from, why he'd have had to have 'come up' to London?
- Monsieur Duveen: I beg your pardon?
- Christopher Foyle: You just asked me when he 'came up' to London.
- Monsieur Duveen: Doesn't everybody come up to London?
- Christopher Foyle: Well, some people 'come down' to London. An awful lot of people are already here.
- Monsieur Duveen: [Duveen realizes he has given himself away. After a long silence] I do not think I have anything to add to what I've already said.
