Who does Christine call to ask about her novel in Part 2: The Journal of Christine Lucas, November 13? What conflicting stories does she hear?

Christine calls Dr. Nash and asks him. Dr. Nash confirms that Christine had once written a novel. In bed that night, Christine asks Ben whether she had ever written anything and he tells her she is imagining things. Ben claims that Christine was a secretary at the time of her accident, although she holds a PhD in literature.
