Badshahi Angti

Feluda and Topshe arrive in Lucknow with Topshe's father to spend the Puja vacation. They reach the house of Dhirendra Kumar Sanyal, a friend of Topshe's father, where the mystery will soon unfold. The stage is set for a case centered on the Emperor's Ring.

Dr. Shrivastav visits Dhirendra Kumar Sanyal and explains that last night a thief attempted to steal the Ring of Aurangzeb, given to him by Pyarilaal Seth. He asks Sanyal to keep the ring safe at his home, heightening the perceived danger around the artifact. The ring's security becomes a pressing matter for everyone involved.

The Ring of Aurangzeb disappears from Dhirendra Kumar Sanyal's home. The theft hints at a planned crime and raises the stakes for Feluda and Topshe. With the ring missing, the investigation moves from suspicion to pursuit.

Feluda and Topshe begin their private investigation, questioning locals and examining possible leads. The missing ring becomes the central mystery driving their sleuthing. They piece together clues that point toward a wider conspiracy.

In the neighbourhood, Feluda meets Bonobihari Sarkar, a man who keeps a menagerie of dangerous creatures. He also encounters Mahabir, Pyarilal Seth's son and a film actor who suspects foul play in his father's death. These encounters broaden the circle of potential suspects and raise the stakes.

The group travels toward Lakshman Jhula Temple in Haridwar to follow a lead connected to the ring. The journey shifts the setting from Lucknow to a sacred site, intensifying the mystery around the artifact.

Near the banks of the Ganga at Haridwar, Feluda lights his cigar and Topshe notices a gleaming object inside Feluda's matchbox. Topshe suspects the gleam might be the Emperor's Ring, confirming the ring's presence. The discovery raises questions about who possesses the ring and how.

The next day they reach Lakshman Jhula and the group splits into two. Feluda and Topshe decide to accompany Bonobiharibabu to continue the search. The new arrangement broadens the investigation and introduces new dynamics.

The driver of their car, Ganesh Guho, is revealed to be Bonobiharibabu's servant in Punjabi disguise. His deception helps set the trap around Feluda and Topshe. The turn adds a layer of danger and intrigue to the case.

Feluda and Topshe are lured into a log house about 1.5 miles from Lakshman Jhula. Bonobiharibabu's plan reaches a critical point as the trap closes in around them. The danger escalates as they confront the conspiracy up close.

Feluda pieces together the clues and exposes Bonobihari babu as the culprit and Pyarilaal Seth's murderer. The mastermind's motive and method are laid bare as the truth comes to light. The ring's significance is clarified in the context of the crime.

In the final moment, Topshe regains consciousness and glimpses Feluda wearing the Badshahi Angti. The case is resolved and the ring is secured once more. The Puja mystery concludes with justice served.
