Inside the crumbling housing estates of Shivaji Enclave, amid the boys playing cricket and housewives chatting from their balconies, winding staircases lead to places where lies a darker side to India's economic boom.
Three months ago, police rescued Theresa Kerketa from one of these tiny two-roomed flats.
For four years, she was kept here by a placement agency for domestic maids, in between stints as a virtual slave to Delhi's middle-class homes.
"They sent me many places - I don't even know the names of the areas," said Kerketa, 45, from a village in Chhattisgarh. "Fifteen days here, one month there. The placement agent kept making excuses and kept me working. She took all my salary."
Often beaten and locked in the homes she was sent to, Kerketa was forced to work long hours and denied contact with her family.
She was not informed when her father and husband died. The police eventually found her when a concerned relative went to a local charity, which traced the agency and rescued her together with the police.
Abuse of migrant maids from Africa and Asia in the Middle East and parts of Southeast Asia is commonly reported.
But the story of Kerketa is the story of many maids and nannies in India, where a surging demand for domestic help is fuelling a business that, in large part, thrives on human trafficking by unregulated placement agencies.
