Also Mrs. Drayton's speech to her busybody assistant who would almost certainly have made something out of the engagement of her boss' daughter to a black man:
Mrs. Drayton: "Now I have some instructions for you. I want you to go straight back to the gallery - Start your motor - When you get to the gallery tell Jennifer that she will be looking after things temporarily, she's to give me a ring if there's anything she can't deal with herself. Then go into the office, and make out a check, for "cash," for the sum of $5,000. Then carefully, but carefully Hilary, remove absolutely everything that might subsequently remind me that you had ever been there, including that yellow thing with the blue bulbs which you have such an affection for. Then take the check, for $5,000, which I feel you deserve, and get - permanently - lost. It's not that I don't want to know you, Hilary - although I don't - it's just that I'm afraid we're not really the sort of people that you can afford to be associated with."
Hilary: [tries to start saying something]
Mrs. Drayton: "Don't speak, Hilary, just... go."
