I'll have you come there some time... and parboil you

Inspector Krogh:

But I'm curious to know why you chose that place to work. Baron Wolf von Frankenstein:
It was my father's. Inspector Krogh:
But without a roof? Baron Wolf von Frankenstein:
Oh, I sealed it up with some heavy canvas. Inspector Krogh:
Don't the sulphur fumes bother you? Baron Wolf von Frankenstein:
No, no no, not at all. Elsa von Frankenstein:
Sulphur fumes? Inspector Krogh:
Oh, uh, forgive me, Baron. Perhaps I shouldn't have mentioned that. I thought madam knew. Elsa von Frankenstein:
Tell me. Baron Wolf von Frankenstein:
Well, you see, darling, our family history states that the structure was built by the Romans over a natural sulphur pit, and used by them as mineral baths. Inspector Krogh:
One of the first health resorts, perhaps. [Chuckling] Inspector Krogh:
Health resort. Baron Wolf von Frankenstein:
Yes, possibly. Inspector Krogh:
But during the succeeding centuries, the boiling sulphur increased in its intensity, until now, I believe, it is over 800 degrees Fahrenheit. Baron Wolf von Frankenstein:
Exactly. Inspector Krogh:
And even the stoutest Roman couldn't venture into that today without being parboiled to the bone in just a few moments. Elsa von Frankenstein:
Wolf, you do pick the strangest places. Inspector Krogh:
I'd like to see how you fixed it up. Baron Wolf von Frankenstein:
I'll have you come there some time... and parboil you
