I remember it very well, but can’t remember it well enough to find it now. This young Russian girl working in a shop is recruited to learn all about the English and to pretend to be a rich American heiress. She is supposed to marry this rich guy, whose dead father set all this up because he was in love with the girl’s mother a while ago. Eventually she turns against the sinister organization that trained her. It had English subtitles, I think translated from Russian. What was the series?

I think it was on Amazon Prime a few years ago.

Thank you!
