Richard Stuart: I assume they paid you well?
Peter Martin: Well handsomely, old chap. Luckiest day in my life when you asked me to check on that license number. Which reminds me - I owe you a tenner.

Dr. Ralph Sawyer: Richard, there's something I want you to understand: in spite of what you think, I'm your friend.
Richard Stuart: I believe you Ralph, I believe you. But you chose a heartwarming way of expressing it tonight.

Sir Howard Nettleton: One final matter, under the heading of new business, gentlemen. Or perhaps I should say old business renewed.

Elizabeth Sutton: And then you would fall into fits of depression that lasted days, sometimes weeks... always inside yourself. And you drank. Richard, you tried to drink yourself to death.
Richard Stuart: Why did you marry me?
Elizabeth Sutton: I loved you. You needed help, and I thought I could give it to you. I loved you. How do you think I feel, when you say I'm part of a plot? I know nothing about it.
Richard Stuart: But you wanted a divorce. Why?
Elizabeth Sutton: I couldn't go on being only a nurse to you.

Peter Martin: I was never really cut out to be a private investigator, you know, sir. House of Commons is more to my taste.
