Seconded, and now you say it I'm wondering if the line I quoted might actually be (only) from the series. The book is excellent, but it's not so funny, or with such snappy dialogue (of course, really, of course TV writers have to add that sort of thing).

'[Puts book down, objecting to Charles also occupying himself] I do think you might talk to me - I've had a very exhausting day. Entertain me. Take me out of myself.'
