Shuklaji Street, in Old Bombay. In Rashid's opium room the air is thick with voices and ghosts: Hindu, Muslim, Christian. A young woman holds a long-stemmed pipe over a flame, her hair falling across her eyes. Men sprawl and mutter in the gloom. Here, they say you introduce only your worst enemy to opium. There is an underworld whisper of a new terror: the Pathar Maar, the stone killer, whose victims are the nameless, invisible poor. In the broken city, there are too many to count.

Stretching across three decades, with an interlude in Mao's China, it portrays a city in collision with itself. With a cast of pimps, pushers, poets, gangsters and eunuchs, it is a journey into a sprawling underworld written in electric and utterly original prose.
