- Sam Wainwright: How're we going to get in there?
- Christopher Foyle: With a key.
- Sam Wainwright: Where'd you get that?
- Christopher Foyle: I 'liberated' it.
- Sam Wainwright: Is this quite legal?
- Christopher Foyle: Well, it's not all legal, but the security service doesn't seem to have much regard for the law.
- [last lines]
- Hilda Pierce: Anything else?
- Christopher Foyle: I'd need a driver.
- [Pierce looks at him]
- Christopher Foyle: You owe it to her. So do I.
- Hilda Pierce: The work we're doing matters. I appreciate our methods may not be to your liking, but it's not our fault; it's just the way it is.
- Arthur Valentine: [to Foyle about the difference between MI5 and police] It's not as if he's committed a crime, Mr. Foyle. This isn't about bodies in the library or stolen petrol coupons or whatever else you got up to in Hastings. It's called 'tradecraft.' It's a different world.
- Christopher Foyle: [about Vessing's murder] His death is too convenient.
- Hilda Pierce: Sometimes things work out that way.
- Hilda Pierce: [In the back seat of her car] I'll come straight to the point. I want you to stay with MI5.
- Christopher Foyle: What on Earth makes you think I'd do that?
- Hilda Pierce: Well, you always wanted to be part of the Service.
- Christopher Foyle: I applied once during the War and was rejected. They had their chance.
- Hilda Pierce: This is no time for hurt feelings. This is business. You're very good at what you do, and I'd like to work with you.
- Christopher Foyle: [Dourly] I haven't got the requisite capacity for deceit.
- Hilda Pierce: Precisely. I need someone I can trust.
- Christopher Foyle: Well, that would be mutual.
- Hilda Pierce: Point taken. Oh, come on, Foyle. what's the alternative? What are you going to do the rest of your life? Fish? Bigger fish to be caught here.

- Max Hoffman: Professor Fraser, Max Hoffman. We met briefly.
- Professor Fraser: At Oak Ridge, Tennessee. Yes, yes, I remember.
- Max Hoffman: I love your work of course, Professor, and I'm, I'm delighted to see you.
- Professor Fraser: My wife, Helen; she works as my assistant.
- Max Hoffman: Ah. Pleased to meet you, Mrs. Fraser.
- Helen Fraser: How do you do?
- Max Hoffman: Ah, come, come. We should finish and get inside. The test will be starting soon.
- Hilda Pierce: Circumstances have arisen in which we feel we have a need of your help.
- Christopher Foyle: Circumstances being... the end of the war?
- Hilda Pierce: If only it had ended. We have a new war, a new enemy.
- Arthur Valentine: The Soviets.
- Hilda Pierce: George Orwell calls it the Cold War, and I think that might prove apposite.
- Christopher Foyle: Given that nothing where you're concerned is ever quite what it seems...
- Hilda Pierce: I don't know what you mean.
- Christopher Foyle: Well, you know as well as I do that Fraser detests communism, Stalin and everything they stand for. By the same token Mrs Wainwright was nowhere near the theatre at the time you stated; neither has she met Vlessing. The photograph is a fake. I know it, you know it; so at some time I'd be grateful if you'd be kind enough to explain to me precisely what's going on.
