Its a journey into a veritable maelstrom. Beginning amid backfiring buses, trundling trams, belching trucks and hundreds of thousands of people crossing the Howrah Bridge every day. It takes you right up to the crossroads of Chitpur, close to the rows of leather shops the Cantonese Chinese set up in this eastern Indian metropolis more than a century ago. Its a journey archetypal of the one undertaken by Hasari Pal, the famished protagonist of Dominique Lapierres 1985 bestseller City of Joy.
