400 Days (novel)

Keshav, preparing to become an IPS officer, is approached by Alia Arora, a neighbor seeking help to find her missing 12-year-old daughter, Siya, who disappeared nine months earlier.

Siya went missing during a family gathering, and the only witness, Suhana, Alia's younger daughter, described the abductor as a man with bracelets, a tattoo, and glowing hair.

While investigating, Keshav gains Suhana's trust and uncovers clues, including suspicious online messages between Siya and someone named "Roy."

Tracking Shastriji to an abandoned sugar factory, Keshav and his team rescue a traumatized Siya, who reveals she was kidnapped and abused under the guise of a religious ritual.

Keshav, letting go of their relationship, shifts focus to expanding Z Detective Agency with Saurabh, including plans for a child security unit.
