Frederick Loren: What husband hasn't wanted to kill his wife at some time during their marriage?
Frederick Loren: The caretakers will leave at midnight, locking us in here until they come back in the morning. Once the door is locked, there's no way out. The windows have bars that a jail would be proud of, and the only door to the outside locks like vault. There's no electricity, no phone, no-one within miles, so no way to call for help.
Watson Pritchard: Like a coffin.
Frederick Loren: It's almost time to lock up the house and then your party will really begin. I wonder how it will end.
Annabelle Loren: And you call this a party?
Frederick Loren: Could be.
Dr. David Trent: Nora, I think you're a little upset. Would you care for a sedative?
Nora Manning: Get out! Get out all of you! All of you get out and leave me alone! Just get out of here.
Frederick Loren: Pritchard, I've had enough of your spook talk.
Watson Pritchard: What's the use of saying, "Good night"?
Frederick Loren: Don't stay up thinking of ways to get rid of me, it makes wrinkles.
Frederick Loren: I am Frederick Loren, and I have rented the house on Haunted Hill tonight so that my wife can give a party. She's so amusing. There'll be food and drink and ghosts, and perhaps even a few murders. You're all invited. If any of you will spend the next twelve hours in this house, I will give you each ten thousand dollars, or your next of kin in case you don't survive. Ah, but here come our other guests.
Annabelle Loren: My husband is sometimes insane with jealousy. Nothing matters to him.
Lance Schroeder: Would he hurt you?
Annabelle Loren: He would kill me if he could.
Frederick Loren: This is Nora Manning, I picked her from the thousands of people who work for me because she needed the ten thousand more than most. She supports her whole family. Isn't she pretty?
Watson Pritchard: Throw these guns away, they won't be any good.
Dr. David Trent: I agree with Pritchard, although not for the same reason.
Watson Pritchard: Only the ghosts in this house are glad we're here.
Frederick Loren: Wasn't there a man who threw his wife into a wine vat or something?
Watson Pritchard: That was in the cellar. There's been a murder almost everywhere in this house.
Frederick Loren: Mr. Pritchard here promises us genuine ghosts.
Watson Pritchard: Seven now. Maybe more before morning.
Annabelle Loren: You're in danger here - we all are.
Nora Manning: From who?
Annabelle Loren: I hope for your sake you never find out.
Watson Pritchard: Four men have been murdered in this house, and three women.
Dr. David Trent: You certainly plan your parties very well, Mr. Loren, four of us are men, three are women, there's a ghost for everybody.
Frederick Loren: It's a pity you didn't know when you started your game of murder that I was playing, too.
Lance Schroeder: If I were gonna haunt somebody, this would certainly be the house I'd do it in.
Annabelle Loren: Dr. Trent, don't you approve of our little party favors?
Dr. David Trent: Suppose Nora had a gun when she was alone in the cellar with the blind woman?
Ruth: Oh, I don't think anyone else is going to walk around in total darkness.
Annabelle Loren: Oh, I'm sure we're not going to go running around the house shooting each other, aren't you?
Dr. David Trent: Who knows? Fear can make people do amazing things.
Chosen answer: Frederick knew that Trent was his wife's lover. That's why Trent was invited. The party was supposed to be an opportunity for Frederick to take revenge.
