An investigative reporter who spent his daughter’s childhood working flies to India to spend her birthday with her. She is gone before he arrives. What begins as a father’s search becomes a route march across a country he does not understand — Goa to Karnataka, Delhi to the foothills — chasing a network that is bigger at every turn than he was told, alongside an agent who has just buried her partner and is no longer certain which side of her own force she is on. The trail ends at the edge of the Himalayas, at a valley that has been taking women for two hundred years and has never once been asked to explain itself.
