I'm not sure specifically as there could be many 'great Indian mystery' true stories. It could be about a historical event, a cultural mystery, or something related to Indian mythology that is based on real - life research or accounts.
The 'great indian mystery' in a real - story might be about the secrets hidden within the deep jungles of India. There could be tales of hidden temples or lost cities. Maybe it has something to do with the unique biodiversity in India and the unexplained behaviors of some animals that are native to the region. It could also be connected to the complex web of Indian mythology and how some of those stories might have been based on real events or people that have been long forgotten or misinterpreted over time.
One possible element could be ancient temples. There are many ancient temples in India with complex architectures and hidden chambers, which might be part of the mystery.
Well, 'The Great Indian Murder' is purely fictional. The plot and characters are crafted by the imagination of the writers, not based on real events or people.
It could be about a significant murder case in India. Maybe it involves complex characters, a detailed crime scene, and the process of the investigation. Without having read it specifically, it's hard to say exactly, but it likely delves into the darker aspects of human nature related to the act of murder in the Indian context.
