Isn it confusing writing fact and fiction?
Not really. It puts me in good company, alongside Neil Gaiman, Kim Newman and Robert Silverberg, although they are all richer than me, obviously. The two kinds of writing do require very different approaches, so I tend to work on one kind for a few months, and then switch to the other. Don’t ever try and write both simultaneously. Ultimately, a large proportion of my factual work forms research material for my fiction.
