A possible concise summary is:
This is a transcript of an episode of CID, a crime drama series. The episode revolves around a mysterious case of two brothers, Aryan and Shishir, who are killed by snake venom without any trace of a snake. Their family claims that a snake's spirit is taking revenge on them for burning its burrow. The CID team investigates the case and finds out that the murders were committed by a robotic snake controlled by Ayush, the third brother, who wanted to inherit the family's wealth. He also used Amit, a man suffering from a rare disease that gave him snake-like teeth, to pose as the snake man and scare the family. The CID team manages to catch Ayush and his girlfriend Myra, who helped him in his plan, and save Amit from their clutches.
I can try to extract the key facts from the text, but it might not be very accurate. Here is what I came up with:
1. The text is a transcript of an episode of a crime show called CID, where the officers investigate mysterious murders involving snake venom and a man with snake-like teeth.
2. The first victim, Aryan, is found dead in his swimming pool with bite marks on his neck. His family claims that he was killed by the spirit of a snake that he had burned alive.
3. The second victim, Shishir, is Aryan's brother and a doctor. He is found dead in his office with bite marks on his feet. The officers find an X-ray that shows a man with snake fangs in his mouth.
4. The third victim, Madan, is an agent who handled the property deals of Aryan and Shishir. He is found dead in his house with bite marks on his chest. The officers also find a metal snake that injects venom and has a camera installed in it.
5. The officers discover that the killer is Ayush, the third brother of Aryan and Shishir, who had sold their land to a builder named Bento without their knowledge. He had also taken help from his girlfriend Myra, a herpetologist who supplied him with venom and the metal snake.
6. Ayush had also used Amit, a man who suffered from a rare disease that made his teeth look like snake fangs, to scare his family and make them believe in the snake spirit story. Amit had a twin brother named Akhil who was unaware of his involvement.
7. The officers manage to catch Ayush and Myra before they can kill the last member of the family, Meenakshi Devi, their mother. They also rescue Amit and Akhil from their clutches.
