Seth Frank: There's one thing I forgot to tell you. I live alone.
Repairman: Just part of my job.
Seth Frank: I hate it when people say that. "Just part of my job." It is your fucking job.

Medical Examiner: Looks like he tried to strangle her.
Seth Frank: He strangled her, then he went to the door to shoot her from behind?
Medical Examiner: He also inspected her vagina.
Seth Frank: He did what? Why?
Laura Simon: Maybe he didn't remember that he did her.
Seth Frank: A strong burglar with a weak mind. Obviously another open-and-shut case.
Seth Frank: Kate, he's on the run and he's scared. And he's right to be scared, 'cause he's gonna get caught. You don't know the heat on this.
Bill Burton: Miss Russell, I should've called the police that night but I was weak. You convinced me to stay silent. I regret that. Know this: every time I see your face, I wanna rip your throat out.
Seth Frank: Pacemaker, my ass.
Kate Whitney: But then you go to the police. That's what innocent people do. They go to the police.
Luther Whitney: Sure. And that young man who was just here, he'd believe me over the President, wouldn't he?
Kate Whitney: Well, why should I believe you?
Luther Whitney: Because I swear to you, Kate. I swear to you on Mattie's grave. Yeah, that's right. Your mother's grave, I'd kill myself before I lied about that.
Kate Whitney: Oh Jesus, Luther.
Luther Whitney: Yeah, I know.
Art Student: You work with your hands, don't you?

Seth Frank: You're saying what? He left town, he skipped the country? What?
Kate Whitney: I'm saying, you won't recognize him. I'm saying, he could be right around the corner.
Luther Whitney: Remember, tomorrow is promised to no-one.
