HERE come the Mumbai boys, the latest arrivistes of literary fiction, resonating with the post-Rushdie buzz of the Big City which they see as a place where the stories are, a metaphor for all India. They have an engaging, self-possessed cool, a surprising lack of guile and lots of Mumbai bonding. Although their books have distinct voices, and they had never met till the New Yorker shoot in London this summer, their lives throw up some striking parallels. They are also the role models for a new kind of Indian fiction-writer whose work is likeable but not remarkable and whose ambitions make up for lack of focus.
