Looking for Movie Title - Spy Drama from before 1990
I saw this movie on TV (Super Channel I think) sometime in the 1980's, so it was made anytime before 1990. It's a war spy movie, and I think it was probably set in World War II. The key elements I recall is that a woman was posing as a maid in order to infiltrate a household of a wealthy general or politician. A man of significant ranking takes a liking to her and invites her to dinner. At dinner, she is unsure how to behave and when a small cooked bird is served, she picks it up and eats it with her hands, at which point everyone stops and watches her. The man then begins to eat with his hands too and everyone else follows suit. It's a bit like Shining Through, but that scene isn't in there and I think was made after the movie I have in mind. Can anyone help? I've been trying to figure this out for years!
