For the last three years the man had been held captive in a brick-and-tin shed just a few minutes’ walk from where the farmers were drinking tea. The marks on his arms weren’t the tell-tale signs of heroin addiction; they came from where his captor, a ruthless modern-day vampire and also a local dairy farmer and respected landowner named Papu Yadhav, punctured his skin with a hollow syringe. He had kept the man captive so he could drain his blood and sell it to blood banks. The man had managed to slip out when Yadhav had forgotten to lock the door behind him.
