““Fortunately, getting hold of people’s garbage was a cinch. Indian detectives were much luckier than their counterparts in, say, America, who were forever rooting around in people’s dustbins down dark, seedy alleyways. In India, one could simply purchase an individual’s trash on the open market. All you had to do was befriend the right rag picker. Tens of thousands of untouchables of all ages still worked as unofficial dustmen and women across the country. Every morning, they came pushing their barrows, calling, “Kooray Wallah!” and took away all the household rubbish. In the colony’s open rubbish dump, surrounded by cows, goats, dogs and crows, they would sift through piles of stinking muck by hand, separating biodegradable waste from the plastic wrappers, aluminium foil, tin cans and glass bottles.””
