Are you fucking kidding me

In this Golden Age detective novel (Latter End by Patricia Wentworth), when the mystery is solved and it's time for the pasted-on heteronormativity parade to conclude with a proposal of marriage, the dude decides to lead into his proposal...

... with one of those long joke rants about how women 'trick' men into 'slavery' with marriage. (!!!)

And then the woman gets angry and starts to tell him where to get off and... he... chastises her for it.

She shouldn't have interrupted his misogynist joke because he was just about to propose apparently???? In fact he says he was just about to go down on one knee. Can you even imagine feeling the need to make a misogynist joke about the institution of marriage as a DIRECT precursor to going on one knee and begging a woman to marry you?!
