Why did you decide to set this book in Mumbai?
My first book was a snapshot of Mumbai’s present, my second traced the city’s past, so it was natural to return and look at Mumbai’s future in the third. But a very dramatic future, where the city has been split along Hindu-Muslim lines, and is facing both terrorism and a nuclear threat from Pakistan. There’s no other Indian city I know well enough to imagine (and describe) in such a chaotic, pre-apocalyptic condition.
