Why did Dev become suspicious when he saw the Sanyasi return to Dahanu about a month after their first meeting?

Mamlatdar Dev's suspicion was sparked by the Sanyasi's premature return, which directly contradicted the instructions he had given. As detailed in Chapter 40, Dev had explicitly told the Sanyasi to come back after a period of two to four months, as another fundraiser was currently active. When Dev saw the Sanyasi arriving in a tonga only about a month later, he expressed his doubt to his son. He wondered why the man had come back so soon and whether he had forgotten their previous conversation. This unexpectedly early reappearance was the primary source of Dev's suspicion, as it seemed to ignore the clear timeline he had established.
