Of course I know that the twins are only words on a page, and I'm certainly not the sort of writer who talks to his characters or harbours any illusions about the creative process. But at the same time, I think it's juvenile and arrogant when literary writers compulsively remind their readers that the characters aren't real. People know that already. The challenge is to make an intelligent reader suspend disbelief, to seduce them into the reality of a narrative.
