THE literary world of London is American enough to have hired one of those endless limousines to carry the Booker winner to the party at a Soho club. Not surprisingly that American stretch superlative, packed with champagne, had trouble rounding a bend towards the entrance of Guildhall where Arundhati Roy had just been awarded the prize. A car was in the way—Salman Rushdie's. It took some frantic hollering from David Godwin, Roy's agent, to alert Rushdie that he was blocking the path. And in a divine symbolism conjured up by some small god, the master of magic realism pulled out of the way to make way for the new star.
