I think you may have your actors wrong. I looked at IMDB and see no crossover, at least in the main actors.
Yeah, I’m not seeing any crossover either.
But now that you mention it, it’s easy to confuse the stories. The time period for Paradise is earlier – mid 1800’s – so the fashions and hairstyles are a bit different.
But this week I was waiting to see the young boy who thinks the store manager killed the guy who forced his way into a partnership with the store owner. 
Yeah, but the story line is very similar, so I see now why I was confused about the wife/kids thing.
I liked the latest episode a lot. Mr. Grove is pulling it together, Mary (sorry, Miss Mardle) has had some good luck and rubbed it in Grove’s face, Lord Loxley continues to be a douchenozzle, and the sexy Henri is back.
Who will die in WWI?
