What was Mamlatdar Dev's internal reaction upon seeing the Sanyasi return to Dahanu much sooner than expected?

Mamlatdar Dev was filled with suspicion when the Sanyasi returned to Dahanu after only about a month had passed. In chapter 40, it's noted that Dev had specifically asked him to come back in two to four months. Seeing the Sanyasi's tonga stop near his house, Dev felt doubtful in his heart and wondered, "It hasn't even been a full month, why has he come here already? Did he forget what was said earlier?" This premature return was described as the very root of Dev's suspicion regarding the Sanyasi's intentions.
