Did Kingsfield know?
This is probably obvious to most of you so please don't respond with "duh", but did Kingsfield know about Hart and his daughter? Did he only feign forgetting who Hart was every time he saw him? Did he give Hart the weekend research assignment to manipulate his daughter's social life? If he did know, did he catch him with her or did he just know?
He didn't get out of the cock-a-doody car!!!
