What was the initial reason for Madhavrao's sudden trip to Nagar, and what did he find when he arrived?

Madhavrao's sudden trip to Nagar was initiated by an urgent telegram from his father-in-law. The message claimed that his mother-in-law was very ill and that he should come immediately. As detailed in Chapter 51, Madhavrao secured Baba's permission and rushed to Nagar. However, upon visiting his father-in-law's home, he discovered that his mother-in-law's health was perfectly fine. This false alarm, which initially caused concern, ultimately served as the pretext for him to be in the right place to meet Dixit and facilitate his journey to Shirdi.
