What does this insult mean? "Your wife, sir, under the pretense of keeping a bawdy house, is a receiver of stolen goods"
Solution 1:
This appears to be intended to be read in a straightforward manner. A 'bawdy house' is an outdated term for a brothel (house of prostitution); a 'receiver of stolen goods' is just that - someone who accepts as part of their business articles stolen from others, for storage, concealment, resale, et cetera. A receiver of stolen goods is also called, in current slang, a 'fence'.
The speaker in the quotation is accusing the wife of the listener of being a fence while pretending to be a madam ([female] operator of a brothel).
