"In the beginning, I used to tell people the not very funny answers, the flip ones: 'From the Idea-of-the-Month Club,' I'd say, or 'From a little ideas shop in Bognor Regis,' 'From a dusty old book full of ideas in my basement,' or even 'From Pete Atkins.' (The last is slightly esoteric, and may need a little explanation. Pete Atkins is a screenwriter and novelist friend of mine, and we decided a while ago that when asked, I would say that I got them from him, and he'd say he got them from me. It seemed to make sense at the time.)
Then I got tired of the not very funny answers, and these days I tell people the truth:
'I make them up,' I tell them. 'Out of my head.'
People don't like this answer. I don't know why not. They look unhappy, as if I'm trying to slip a fast one past them. As if there's a huge secret, and, for reasons of my own, I'm not telling them how it's done."
