Professor Edward C. Burke: Lucille, I am going to reveal to you that your father did not die by suicide!
Lucille Balfour: You can't mean that someone killed my father!
Professor Edward C. Burke: am going to ask you to put yourself in my hands... to do whatever I say... no matter how trying it may be.
Professor Edward C. Burke: I want you to promise to keep this a secret... from everyone.
Lucille Balfour: Mr. Burke, you make me feel that I should trust you... that you are my friend.
Arthur Hibbs: What was he saying to you?
Lucille Balfour: I can't tell you! Please don't ask me!
Arthur Hibbs: I don't trust him! Why wouldn't he let Uncle send for the police last night?
Arthur Hibbs: And now he is getting you under his spell!
Lucille Balfour: Oh, Arthur... he says that someone killed my father!

Lucille Balfour: I'm terribly frightened, Sir James! A voice keeps calling to me from the garden!

Miss Smithson, the New Maid: Honest, Sir James... they're dead people from the grave! Vampires is what they are!
Sir.James Hamlin: Professor Burke is to be our house-guest, Williams. Have rooms prepared for him.
Professor Edward C. Burke: It's unnerving, Mr. Hibbs! The new maid swears to your Uncle that she saw living dead people in the Balfour house!
Sir.James Hamlin: Burke, I've called you in again because I believe these strange people leasing Balfour's house link up with his death.
Professor Edward C. Burke: We found his note... and his own pistol beside him! That's suicide, isn't it?
Sir.James Hamlin: Then what can it all mean? Mysterious people! Lights! Weird noises! And come... see this!

Sir.James Hamlin: Burke... look! It is Roger Balfour!
Sir.James Hamlin: Come, Burke! We're helpless before such creatures as these!
Arthur Hibbs: For one who doesn't believe in vampires, you've taken a sudden interest in them!
Professor Edward C. Burke: Perhaps it's for the same reason that you did, Mr. Hibbs!
Professor Edward C. Burke: Be brave, my dear. Follow my instructions tonight.
Professor Edward C. Burke: Young man, I'll take one of your cigars... and have a little talk with you.
Professor Edward C. Burke: I've suspected you for a long time, Hibbs.
Arthur Hibbs: Yes? And I've suspected you!
