My legs, arms, back and neck hurt. With fame comes responsibility. I have to keep a secret diary. To maintain my reputation, the diary should be big, with more pages than my 832-page novel. Since I am small-built, I have to climb a chair to reach the desk where the diary is kept next to The Luminaries (hence the aches) which fetched me The Man Booker Prize and £50,000 in prize money. Of course, all kinds of queries were raised when the prize was announced. At 28, how could one write such a weighty book? What special facilities were provided to the judges so that they could read this longest-ever novel? Was it true that The Luminaries was an entry for the 2012 Man Booker which could be considered only for 2013 because most of the judges could not finish the book last year. How on earth could you create characters for this 832-page behemoth?
