Castle, Season 1

Castle:
What about the guy in 8B?

Beckett:
Who?

Castle:
[his murder theory] 8B. You see him every day, only you never notice him. But he noticed Sara. She's young, beautiful, the kind of girl that a guy like him would never have a chance with. [looks at Beckett pointedly] We all know girls like that don't we? [continuing] Well, at first, it's just a game. Figure out her schedule. When does she do her laundry? When is she alone? Until it becomes something more, something that he can't control. Well, he uses the stairs, obviously, to avoid the elevator's cameras. And then he just waits, concealed in the shadows. When she comes into that laundry room, he pounces. When he looked into her vacant, lifeless eyes, he wanted to tell her he never meant to kill her. All he ever wanted was to be noticed. That's when he felt the heat of that dryer on his skin. So he picks up her limp body in his arms and gently places it inside. He almost smiled at his good fortune when he found the quarter in his pocket, slipping it into the slot. Buying him the time to do what he does best... disappear. [pauses, then continues] Just saying, better story. Coffee?

Montgomery:
Let see what we can find out about those neighbors. [walking away and turning back briefly] And someone better tell me who the hell lives in 8B!
