If you have read the books, please answer my question below.

Spoiler

I remember from the books that it was implied that Stannis and Melisansdre were 'enjoying' each others' company, but I don't think that it was out right displayed like it was in the episode last week.

My question is, was it always implied in the books that Melisandre used Stannis' sperm to create the demon baby/shadow monster that kills Renly? I don't remember that from my reading, but that is the impression that I got from the show.
