I’m always fascinated by genres that actually need to create effects. The most obvious, and I assume the easiest, is probably pornography, but moving on from there (and I’ll probably get loads of people writing to me saying ‘no, no, no. Pornography is really hard!’), horror and humour are both in the same category. If you’re not scared, it hasn’t worked, and if you’re not laughing, it hasn’t worked. I probably write like I cook, that’s to say with the same attitude. Who’s to say you can’t add this to that?
