- O'Shea: A hundred and sixty thousand pounds is a matter for the police. A million is a political offensive. It also lasts longer.
- O'Shea: [about Norgate] He was a mining engineer, but he found it easier to extract gold from banks than from frozen streams.
- Capt. Monty Fitch: There is nothing wrong with soldiering. You see, I'm never called on to think in my profession. And I'd rather like to. Just once. And then I'd know...
- Charles Norgate: Know what?
- Capt. Monty Fitch: Whether I stay a soldier because there's nothing else I can do, or because I choose to. I'd probably make a fearful hash of it. Thinking I mean.
- Capt. Monty Fitch: The colonel has given me the entire weekend on duty.
- Charles Norgate: That's rough.
- Capt. Monty Fitch: Bank holiday in the bank.
- Capt. Monty Fitch: What do you use?
- Charles Norgate: A rod. A line.
- Capt. Monty Fitch: Lure, my dear, sir. What do you lure them with?
- Iris Muldoon: I understand you've taken a room at the Strand Hotel. Isn't that conspicuous?
- Charles Norgate: So I'm told.
- O'Shea: It won't be easy. These walls are considered impregnable. They have withstood wars, rats, the dreams of thieves, and time. But, remember this, my talented children, the brains that built them were human and as fallible as your's and mine. Somewhere, the old lady has a weakness.
- Iris Muldoon: I want you to forget what happened in New York.
- Charles Norgate: Who said I remembered?
- Charles Norgate: You're lonely.
- Iris Muldoon: You disgust me.
- Charles Norgate: Are you sure you haven't got it the wrong way around?
- Iris Muldoon: Yes, that too. I disgust myself.
- Charles Norgate: Come back to me, Iris.
- Walsh: You are terrible sometimes. You can chill a man to the bone, then, you turn, take some little step - the way you move - it starts the blood pounding in my throat.
- Capt. Monty Fitch: Oh, what it is to get away from that harrowing round of duties.
- Charles Norgate: I thought you liked the guards?
- Capt. Monty Fitch: Nothing wrong with the guards, old boy. It's the guarding.
- O'Shea: Remember, if you fail us now, the Movement is finished - and that's the truth.
- Iris Muldoon: Truth? We're nothing but puppets dancing on a string - and that's the truth.
- O'Shea: The answer to that, Mrs. Muldoon, is that my truth is truer than yours.
