You can't build a plot out of jokes. You need tragic relief. And you need to let people know that when a lot of frightened people are running around with edged weaponry, there are deaths. Stupid deaths, usually. I'm not writing 'The A-Team' - if there's a fight going on, people will get hurt. Not letting this happen would be a betrayal.
The most watched programme on the BBC, after the news, is probably 'Doctor Who.' What has happened is that science fiction has been subsumed into modern literature. There are grandparents out there who speak Klingon, who are quite capable of holding down a job. No one would think twice now about a parallel universe.
I particularly admire are Mark Twain and Jerome K. Jerome who wrote in a certain tone of voice which was humane and understanding of humanity, but always ready to annotate its little foibles. I think I'd lay my cards down on that, and say that it's that that I'm trying to do.
