- Count Karnstein: What's the meaning of this, Weil? Out witch-hunting again? You've come to the wrong place.
- Gustav Weil: We seek the servants of the devil.
- Count Karnstein: Well, you've found one. Me! Now get out!
- Count Karnstein: [pointing to ancestral portraits] They knew! They didn't play at being wicked. They worshipped the devil and he taught them delights that you will never know! Of punishment: inflicting and receiving it. Of torture. And death. Yes, of death and of pleasures beyond the grave. Something you could not even comprehend! But I know.
- Gustav Weil: God is calling on us who believe in His holy word to stamp out that evil, to seek out the devil worshippers, and to purify their spirits so that they may find mercy at the seat of the Lord... by burning them!
- Dietrich: [watching staged black mass with Count Karnstein] Your Excellency is pleased with the entertainment? He's calling out the devil.
- Count Karnstein: Well, so can I. Or you. But will the devil come?
- Dietrich: Fresh blood?
- Count Karnstein: The guts of a chicken or a suckling pig. The devil won't be cheated as easily as that, Dietrich.
- Dietrich: Your Excellency is pleased with the girl?
- Count Karnstein: A peasant, bought for a few gold coins. Can you never find anything new? Different?
- Dietrich: Well, you know, my lord, I try.
- Count Karnstein: They say that Gustav Weil has two pretty nieces staying with him. Twins. That would be something different.
- Dietrich: Your Excellency is pleased to joke. We do not want trouble with a man like Weil.
- Count Karnstein: I don't know why I employ you, Dietrich. You bore me, personally, and everything you do for me I find tedious, including this charade.
