Cornelia van Gorder: [Anderson picks up a gun after Fleming is killed] Why that's my revolver!
Detective Anderson: [inspects it] One shot fired.
Cornelia van Gorder: I fired that shot myself last night.
Detective Anderson: Nice try, Miss Van Gorder, but I'm placing your niece under arrest for the murder of Courtleigh Fleming.
Cornelia van Gorder: You can't arrest her without a coroner's verdict, and you'll have to wait on Dr. Vanrees for that.
Detective Anderson: Miss Van Gorder, when I find a need to make an arrest, I'll make it! And I won't wait for any coroner's verdict.

Cornelia van Gorder: Now what on Earth are you doing?

[throws a trap on a chain out the window]
Lizzie Allen: And I've got the other end fastened to the bed.

Cornelia van Gorder: We'll get to the bottom of this. I've sent for detectives.
The Caretaker: Detectives won't do no good. The entire police force won't do no good.
[nervous laugh]
The Caretaker: They can't stop ghosts.

Cornelia van Gorder: Who did that?
The Caretaker: I don't know... this house gets on my nerves, they won't let me sleep.
Lizzie Allen: Don't trust him, caretaker means servant... Bat!
Cornelia van Gorder: Who won't let you sleep?
The Caretaker: The ghosts... he slams doors, and there's no one there to slam them... he opens windows, and I can't see nothing... he rolls things down the stairs, and there's no one there to make them roll... that ain't all, he whispers to me, from behind the wall.
[a loud scream is heard]
The Caretaker: Listen, he's here again... stay here long enough, you'll see.
Lizzie Allen: Let's go back to the city.
