- The Unknown: What I'd like to know is how did you get the dope from headquarters on this case?
- Detective Anderson: The same way I get everything, with my mind. I've got the greatest brain that ever existed.
- Cornelia van Gorder: Why do you suppose the servants left? I don't think the housemaid ever had a pain in her side, and I don't think the cook ever had a sister. And her sister didn't have twins. They was just scared stiff and they ran away... because, they saw IT.
- Lizzie Allen: You're a fool. Keep quiet.
- Lizzie Allen: I won't keep quiet. I've worked for you for twenty years and I guess I have a right to speak my mind.
- Cornelia van Gorder: You haven't got a mind.
- Lizzie Allen: If I had one, you wouldn't let me use it. I stuck by you when you was a Theosophist and a suffragettist, and I've seen you through socialism, Fletcherism, and rheumatism, but when it comes to spookism, I'm through!
- Cornelia van Gorder: Shut up!
- Police captain: [after The Bat has committed a daring crime under the noses of the police] Get me Detective Anderson! No cheap crook is going to make a monkey out of me and get away with it!
- Cornelia van Gorder: Now what on Earth are you doing?
- Lizzie Allen: I'm setting a bear trap for the Bat, in case he decides to come flying around here.
- [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: 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.
- Lizzie Allen: That new gardener, I don't like his looks, suppose'n he's the Bat?
- Cornelia van Gorder: I know he's not a gardener, because uticaria is hives, rubeola is measles, and alopecia is baldness.
- Lizzie Allen: And knowing all this, you're going to let him stay here?
- Cornelia van Gorder: I will, until I find out why my niece brought him here.
- Detective Anderson: Did you do much looking around?
- Detective Jones: Did I? That's just what I was doing when somebody socked me with a piano.
- Dale Van Gorder: We didn't mean to fool you, auntie.
- Cornelia van Gorder: You didn't... gardeners don't have manicured fingernails.
- 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: [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.
- Detective Jones: Hey, what type of joint is this?
- Detective Anderson: Who are you?
- Detective Jones: Who am I? Who do you think I am? W.T. Jones. Super-sleuth of Oakdale County.
- Lizzie Allen: Aren't you going to take me up with you?
- Cornelia van Gorder: You're nothing but trouble on the ground floor, you'll be a nuisance on the roof.
- [goes up the stairs]
- Cornelia van Gorder: If I yell you come up!
- Detective Jones: Who, me?
- Cornelia van Gorder: Yes you!
- Cornelia van Gorder: Dale, get some whiskey.
- Detective Jones: You mean to tell me you've got booze in the house?
- Cornelia van Gorder: Yes, for emergencies.
- Detective Jones: So that's why everybody's trying to break into this place.
- Cornelia van Gorder: Get the Ouija board.
- Lizzie Allen: It's got the Bible on top of it, keeping it quiet.
- Dale Van Gorder: Sorry, Auntie, the train was late. But nice Mr. Fleming was good enough to give me a ride from the station.
- Cornelia van Gorder: I should think the less you have to do with Richard Fleming, the better.
- Dale Van Gorder: Oh, but why, Auntie?
- Cornelia van Gorder: I don't like him, he leased this house to me.
- Lizzie Allen: [after The Bat gets trapped in her bear trap outside] I caught The Bat! I caught The Bat! I caught The Bat! I caught The Bat!
