Beckett and Castle in “Get A Clue”

Beckett

So the FBI doesn't have any murder in their database that match this M.O.

Castle

Which leaves us with my theory. Our victim was dabbling with black magic, and she conjured up a demon.

Beckett

Or, maybe, she ran afoul of some obscure religious sect and they sacrificed her to their pagan deity.

Castle

What are you doing?

Beckett

Making stuff up, just like you do.

Castle

Yeah, because that's my job. It's your job to follow the evidence. You're messing with the natural order of things.
