- Eugéne François Vidocq: Sometimes the chains of matrimony are so heavy they have to be carried by three.
- Eugéne François Vidocq: There's no fool so dangerous as a fool with brains.
- Loretta: Except a woman so foolish as to fall in love.
- Eugéne François Vidocq: In crime, as in love, there are only those who do, and those who don't dare.
- Eugéne François Vidocq: What is the trouble madame?
- Marquise De Pierremont: Satan is there! Satan! Between the bishops tombstone and the grave of madame...
- Eugéne François Vidocq: Oh Satan? I trust he's not after the bishop's soul.
- Marquise De Pierremont: I trust you'll catch my little imp, if your legs are as quick as your wit, monsieur!
- Eugéne François Vidocq: Madame, your lackey has legs, a gentleman can only offer his wit.
- Marquise De Pierremont: What chic! Now what a gallant charmer, my rogue of a monkey is down right mesmerized!
- Eugéne François Vidocq: It isn't a question of morals, but of manners. A man who's capable of killing with a knife is quite liable to eat with one.
- Loretta: Really, I... I should call the police.
- Eugéne François Vidocq: Don't call them until I've bought you another hat.
- Loretta: Another?... another hat? Well, I admit I'm not so rich that I can afford to throw them in the gutter. Hats don't grow on trees, you know!
- Eugéne François Vidocq: I know that some of the latest fashions look as if they did.
- Eugéne François Vidocq: Try to see further than the point of your knife. If I become chief of police, we'll have a chance to loot the city.
- Emile Vernet: Loot a city? What does that mean?
- Eugéne François Vidocq: Conservatively... fifteen million.
- Emile Vernet: Fifteen...?
- Eugéne François Vidocq: ...million... in gold.
- Emile Vernet: Where is it?
- Eugéne François Vidocq: In the vault of the Bank of Paris.
- Emile Vernet: Bank of Paris? Hmmmnnnn... Such a job! No! Too big for the two of us!
- Eugéne François Vidocq: Yes, but we can enlist the support of your dear family.
- Emile Vernet: Yeah, family!... Yeah, but we'll have to give them a cut.
- Eugéne François Vidocq: A small percentage.
- Emile Vernet: Nah... no percentage! Just a cut!
- Eugéne François Vidocq: Like most good men, I came from a poor but honest family - a little poorer than honest. The difference accounted for my being born in prison. Whenever poor mama expected another baby and consequently needed shelter, it was her custom to steal a loaf of bread and go to prison. She had stolen eleven loaves, served eleven sentences, and had eleven children, when to her misfortunes were added a twelfth. When poor mama went to a better world, leaving me to make the best of this one, what is more natural than that I should often return to the happy scene of my earliest childhood?
- Eugéne François Vidocq: Love and crime make incompatible bedfellows. The most perfect criminal can be traced in court if he leaves his heart behind him as a clue.
- Eugéne François Vidocq: Remarkable for one of her sex. I'm afraid a fourth time and I'm liable to fall in love with her.
- Emile Vernet: Fall in love - lay off. That's how they collared my cousin, Pierre... . He went dancing one night and didn't get home for fifty years.
- Marquise De Pierremont: All men are criminals in the light of reason. One steals our hearts, the other our jewels. Fortunately, my dear boy, you were as skillful at one as at the other.
- Marquise De Pierremont: Uh, what was I saying?
- Eugéne François Vidocq: Behave, Satan.
- [Her monkey]
- Marquise De Pierremont: Exactly.
- Loretta: Time has made you even more intriguing. Surely, you're conceited enough to realize no woman could ever forget you, or give you up.
- Mimi De Pierremont: I knew it from the beginning.
- Eugéne François Vidocq: Knew what?
- Mimi De Pierremont: That no man is a saint.
- Therese De Pierremont: Father?
- Priest: Yes?
- Therese De Pierremont: If a man's face is good, can his heart be evil?
- Priest: My child, in all of us, there is a St. George and a dragon. That is the true meaning of the legend of St. George. Evil can be slain only by faith.
- Eugéne François Vidocq: I've had so many names, I'm afraid I don't remember the most recent one.
- Loretta: Perhaps you'll refresh your memory by consulting the visiting card in your wallet.
- Eugéne François Vidocq: My dear lady, after our visit to the hat shop, my wallet is empty.
- Loretta: Is that all we mean to each other - an empty wallet?
- Marquise De Pierremont: [In the cemetery] You see, all of them here were my friends - or pretended to be.
- Marquise De Pierremont: It is not good to speak of the dead in their presence. It will be safer to nibble at his reputation over a cup of chocolate.
- Eugéne François Vidocq: My dear Emile, we always have enough strength to bear the misfortunes of others.
- Eugéne François Vidocq: Love and crime make incompatible bedfellows. The most perfect criminal can be traced and caught when he leaves his heart behind him as a clue. Only the heartless succeed in crime, as in love.
- Loretta: Is the great detective trying to be funny, or have you really taken up peddling? Hmm. Not a bad idea. Perhaps you'd like me to accompany you on the streets with a harp doing, "Throw me a penny, I am sick, and my husband is a lunatic."
- Emile Vernet: It's that girl. You think she's worth 50 million Francs?
- Eugéne François Vidocq: Oh, heh, much more than that.
- Eugéne François Vidocq: Uh, madame, your lacky has legs. A gentleman can only offer his wit.
- Marquise De Pierremont: What chic!
- Prefect of Police Richet: That man I've been pursuing for years - he's the real criminal. You've got to find him. I've failed, but you won't. Promise me you'll put an end to him.
- Eugéne François Vidocq: I have already put an end to him.
- Prefect of Police Richet: You have? How? You're a great detective - greater than I ever was.
- Emile Vernet: Look at that old Christmas tree parading around with diamonds big as tomb stones. If we could only get our hands on...
- Eugéne François Vidocq: It isn't done, Emile, to put such thoughts into words.
- Eugéne François Vidocq: Looking back on the phantasmagoria of my life, I have often wondered what would have happened had I been on time for my appointment with the past. Of course, Richet was only a fool, but a fool is always dangerous and above all, a jealous fool who had set his cat to catch a shadow.
- Eugéne François Vidocq: You're very lovely, Therese.
- Therese De Pierremont: Am I as lovely as the other lady?
- Eugéne François Vidocq: In her eyes I see myself as I am. But in yours, I see myself as I should be. As I hope to be.
- Therese De Pierremont: I stole them for you.
- Eugéne François Vidocq: Thank you, but you don't expect me to marry a thief.
- Therese De Pierremont: What can I do? If you won't come over to my side, I'll have to go over to yours.
- Eugéne François Vidocq: Darling, I promise you whichever side you're on, we'll be there together.
