"It is a work of psychogeography, albeit in a less explicit sense than Iain Sinclair's or Will Self's. It had to be fiction though, because I needed that freedom of including whatever belonged, and cutting out whatever didn't. The main fiction in it was matching Julius' generous and self-concealing character to New York's generous and self-concealing character. I think this also adds to my answer about New York's personality in the book."
