A little over five hours by road northeast of Nagpur into Madhya Pradesh, over single-lane roads low on traffic, through small towns half-asleep in their usual rhythms, past unexceptional fields somewhat wilted from road dust and then the occasional patch of violently green wheatgrass or mustard, the jungle begins to take over, and a little while later, we pull in over a bumpy dirt track into a little camp of pointy-topped, mushroom-coloured habitations that seem straight out of a fanciful dream (a feeling heightened if you arrive, as I did, on a misty night, when rows of paraffin lanterns line the paths).
