Chacha began to investigate, searching for clues. He discovered a hidden room, sealed behind a bookshelf. Inside, they found a series of cryptic messages and an old diary belonging to Rajkumar Seth.
The diary revealed that Seth had been involved in some shady dealings and had hidden his wealth in various secret locations. However, he had also made some enemies, who might be behind the haunting.
As they waited for the "ghost" to appear, Chacha and Sabrina prepared a trap. When the fake ghost arrived, Chacha confronted him, exposing his true identity.
