Where can I find - Behind the closed doors

Behind the closed doors Vicomte had begun a game, so could not talk to us, but some more officers were introduced, and, after the usual bowing, we began to talk. I felt I could have slapped her. The Baronne has been arranging it, and he is to be brought with his parent to breakfast, to sample her. They have not seen one another yet, and it has been difficult to get him to face the behind the closed doors seriously.
