Castle, Season 6

Castle:
She ever get any visitors? Possible that she, uh, worked out of the home?

Hotel Worker:
No, sir. That is not possible.

Beckett:
Well, then who paid for the rent?

Hotel Worker:
[Haughtily] Detective, we have a well-earned reputation for discretion and guarding the privacy of our clients.

Beckett:
Privacy ends when murder begins. Now I want the name of whoever is paying for this unit. And if you don't have that, then go get it.

[Worker sighs and then leaves]

Castle:
I love when you get angry. I mean, at other people, besides me.
