A comment online was stop interrupting her and let her get on with the third book!
This interview with Hilary Mantel is actually from 2015, so she's had some time since to get on with the third and final book in her great Wolf Hall trilogy. The interview is very good on the process of writing and research she has. Her favourite novel is Robert Louis Stevenson's Kidnapped, surprisingly enough; a book I read when I was at school but should revisit I think. A cracking adventure. I've been very lucky with my choice of books this year; long may that continue.
