- Dr. Jekyll: I walked the streets, brooding on the bitter irony that all I wanted to do for humanity, for life, would be cheated by death... unless I could cheat death.
- Sister Hyde: There will be a different kind of victim tonight; not a streetwalker. A fresh young virgin. That will end the tug-of-war between us.
- Dr. Jekyll: Hormones. Female hormones. Now, what is it that gives a woman's skin that silken texture? Why does she keep her hair when so many men lose theirs? Hormones! Female hormones!
- Dr. Jekyll: I shall need more. As many as you can get.
- William Burke: Others? It might cost you a little more.
- Dr. Jekyll: You'll be paid.
- William Burke: Then, I think we could supply your needs. Yes, I think we can do that. We'll be in touch.
- Professor Robertson: My dear Dr. Jekyll, you work yourself far too hard. Why, only last night I passed here, well after midnight, and your light was still burning.
- Dr. Jekyll: I was working. What were you doing at that hour?
- Professor Robertson: Oh, I was on the job too. Research, you know? Delicious blonde fragment from the chorus of the Alhambra.
- Byker: [to Dr. Jekyll who's selecting a female corpse in the morgue] Hope you're not going to choose her. I'm kind of fond of her.
- Dr. Jekyll: They must be female. No more than 20 years old.
- Byker: Oh, I shan't forget. It's exactly how I like them.
- William Burke: All in the cause of science, eh, Doctor?
- William Hare: I mean, you got to do bad to do good, ain't ya?
- Susan Spencer: I'm sorry you were too busy to dine with us last night, Dr. Jekyll. I didn't realize you had a prior engagement. My brother tells me she's very attractive.
- Dr. Jekyll: He saw her? But, how did he - your brother saw her?
- Susan Spencer: Last night. Didn't she tell you?
- Dr. Jekyll: Oh, you mean my - my sister?
- Susan Spencer: Sister?
- Dr. Jekyll: Yes.
- Susan Spencer: Oh, I look forward to meeting her someday. What is her name?
- Dr. Jekyll: Uhm - Hyde. Her name is Hyde, Mrs. Hyde.
- Howard Spencer: He has a sister? And a widow, you said? That is interesting news. That's quite made my day. She is a damn pretty woman.
- Mrs. Spencer: Howard!
- Howard Spencer: Oh. Sorry, mother.
- Dr. Jekyll: It was male before I treated it.
- Professor Robertson: You mean, you changed it's sex?
- Dr. Jekyll: I invested it with female characteristics, yes.
- Professor Robertson: Keep away from me, my boy. I'm having far too much fun the way I am.
- Professor Robertson: No need to be embarrassed, dear chap. Perfectly normal and natural. Been preaching it to you for years. Get a woman in your life - a good woman - and one day you'll wake up, you'll look at yourself in the mirror, and you'll see a changed man.
- Dr. Jekyll: Robertson, I - I don't mean to be rude, but...
- Professor Robertson: Understand, dear chap. Understand absolutely. In two is company, in three - a positive deviation.
- Dr. Jekyll: [voice over] I was caught in a terrible trap. To continue my work I needed sister Hyde. Yet, all the time I became more and more aware of her growing dominance within me. A dominance I no longer had the strength to fight, contain, or control.
- Dr. Jekyll: I'll be rid of you!
- Sister Hyde: It is I who exist, Dr. Jekyll, not you. It is I who will be rid of you! Rid of you! Rid of you! Rid of you!
- Sister Hyde: There must be somewhere else, somewhere quieter. More discreet.
- Professor Robertson: There are my rooms, of course. But, then you would be - unchaperoned.
- Sister Hyde: That would be an adventure.
- Sister Hyde: I'm his sister.
- Professor Robertson: The deuce you are! He never mentioned that he had a sister. And such a sister.
- Susan Spencer: I've been longing to meet you. I - know your brother quite well.
- Sister Hyde: So, I gather. He's very fond of you, isn't he?
- Susan Spencer: [smiles] He said that?
- Sister Hyde: There are no secrets between my brother and I. None. Yes, he's very fond of you. And I am very fond of your brother. A fascinating situation, don't you think?
- Howard Spencer: [on the couch, hand be between Hyde's legs, kissing] Mmm. If you - if you knew what you - do to a man. Oh, if you could imagine what a man feels when he...
- Sister Hyde: But, I can - imagine it.
- Tavern Waitress: What'd you like, gentlemen?
- William Burke: You, for a start.
- Tavern Waitress: Oh. Cheeky, aren't we?
- William Burke: [tossing a handful of coins up in the air] I can afford to be.
- Tavern Waitress: And, uhm, what would a girl have to do to get that, then?
- William Burke: Nothing that's not in her nature. We'll have two pints of porter - for the time being.
- Tavern Waitress: Have what you want - as long as you can pay.
- Betsy: Oh, a real gentleman. I knew it. I'm very popular with real gentlemen - on account of the fact that I speak fluent French.
- [starts undressing]
- Betsy: 'Course, I come from very good stock too, you know. My father was a gentleman. But he wasn't gentleman enough to marry me mother. Oh, that's by-the-by. Point is, I can tell a *real* gentleman. Not by the way he looks; but, well, real gentlemen, they have such - sophisticated taste in - certain things. A quiet one, are we? You've hardly said a word. Well, if you'd lost the use of your tongue, perhaps you haven't lost the use of your hands. Undo me. Please, dear. Oh. I hope you're not going to be too vigorous, dear. I mean, it's been a long, hard night...
