Quote context

[...]

- Well, I am willing to believe you. I, too, am being blackmailed for something I didn't do.

- Me, too.

- And me.

- Not me.

- You're not being blackmailed?

- I'm being blackmailed all right. But I did what I'm being blackmailed for.

- What did you do?

- To be perfectly frank, I run a specialized hotel and a telephone service which provides gentlemen with the company of a young lady for a short while.

- Yeah? What's the phone number?

- So how did you know Colonel Mustard works in Washington? Is he one of your clients?

- Certainly not.

- I was asking Miss Scarlet.

- Well, you tell them it's not true.

- It's not true.

- Is that true?

- No, it's not true.

- Aha! So it is true! A double negative.

- A double negative? Do you mean you have photographs?

- That sounds like a confession to me. In fact, the double negative has led to proof positive. I'm afraid you gave yourself away.

- Are you trying to make me look stupid in front of the other guests?

- You don't need any help from me, sir.

- That's right!

- Seriously, I don't see what's so terrible about Colonel Mustard visiting a house of ill fame. Most soldiers do, don't they?

- Oh, please!

- But he holds a sensitive security post in the Pentagon.

- And, Colonel, you drive a very expensive car for someone who lives on a colonel's pay.
