H, it was a different time. I think many women put up with things like this. Don't forget, they didn't work and if they got a divorce, which was still a fairly uncommon thing, they would have to fend for themselves. Times have changed in many ways. Better in some ways and not in others.
I like the way he was trying to choke the neighbor and didn't even stop when the police was knocking on the door so when they kicked the door in, he was still chocking the guy. hahah
One thing was left unanswered. Did they recover his suitcase where he had the mistress' diary? We don't know if it had been loaded on. That would definitely clear the husband's name.
