Castle, Season 7

Beckett:
Really? That's how the Devil is gonna kill someone? Using a broken pool stick?

Castle:
Or perhaps the Prince of Darkness is trying to make a point. You live by the cue, you die by the cue.

Beckett:
I thought he usually just released the hellhounds.

Castle:
All right, then how do you explain what we just saw back there?

Beckett:
Easy. Will didn't close the door all the way when he came back in. Our window was open, the killer came through it, and this huge gust of wind forced the door open, and then shut when they left.

Castle:
Except Will lives on the 19th floor. With no fire escape.

Beckett:
Come on, Castle. You know that there are plenty of ways to access windows on high-level floors without a fire escape.

Castle:
Yes. If you're Spider-Man.

Beckett:
Our killer's not Spider-Man.

Castle:
Agreed. Because it's the Devil.
