It took a while to get used to the world that I had stepped into that morning. I picked my way past slushy drains and garbage heaps, avoiding collision with a man carrying a tray of upturned clay faces, jumping aside when a woman tipped her bucket of dirty laundry water onto the road. Steeling my nerves with the thought that people such as Raghu Rai and Raghubir Singh have roamed these lanes camera in hand, I marched through Kumortuli.
