I do no research. Given that I’ve just written a book that revolves around two London Met police detectives, this might seem a little foolhardy. I have no real idea what detectives do with their days. So I made some guesses. I suppose that they must investigate things. I tried to imagine what that might be like. I’ve seen the same films and TV shows that you have. I’ve read the same sorts of cheap thrillers. And I know that everything is fiction. Absolutely everything. Research is its own slow fiction, a process of reassurance for the author. I don’t want reassurance. I like writing out of confusion, panic, a sense of everything being perilously close to collapse. So I try to embrace the fiction of all things.
