Some 90 km west of Gurgaon, lies Khanpur. The drive into this village in Jhajjar district is picturesque — lush green fields scattered with yellow mustard flowers line both sides of the highway, and brightly painted buildings, temples and trees dot the landscape. Some distance into Khanpur, though, the surroundings change abruptly. Here, the ground has been cleared of all vegetation, truck and heavy equipment tyre marks mar the reddish-brown soil and beyond, in a compound surrounded by dusty trees, huge cement chimneys jut into the sky.
