Castle, Season 3

[After telling Damian that they also found the man who killed his father years ago]

Damian:
Wow, this is… It is pretty overwhelming. I got a plane to catch, so maybe we should just talk about this later.

Castle:
Michael told the cops you got in touch with him. Asked him if he wanted to make a lot of money for one night's work. You gave him your Rolex and your car as a down payment. When your inheritance came through, he got a half million dollars and a one-way ticket to Los Angeles. He still has your Rolex…and a map that you drew of your father's house, with a path leading straight to his bedroom.

Damian:
Rick, he's lying.

Castle:
[voice hardening] Tell me you didn't do it.

Damian:

Castle:
Tell me I haven't been believing in you all this time for nothing.

[doorbell rings]

Castle:
That's them. Detective Salazar and some New York detectives. They're here to take you in. [rising up from his seat] I told them you'd be a gentleman.
