Why did Mamlatdar Dev become suspicious when the Sanyasi returned to Dahanu?

Mamlatdar Dev became suspicious because the Sanyasi returned much earlier than expected. Dev had specifically told him to come back after two to four months to seek donations for cow protection. However, as Chapter 40 recounts, the Sanyasi came back in about a month. This premature return made Dev doubt his intentions, wondering if the Sanyasi had forgotten their previous conversation. The suspicion was rooted in the fact that the Sanyasi was not adhering to the timeline Dev had laid out, making Dev question the reason for his early reappearance.
