Why was the summary of the Shri Sai Satcharitra not written by the original author, Hemadpant, and how was this situation addressed?

According to Chapter 53, the original author, Hemadpant (Dabholkar), had promised to review the book and provide a summary to complete it. However, he suddenly passed away, leaving his family and fellow devotees grieved and his work unfinished. His records, which were written on scraps of paper, were gathered by his son, Gajanan, but the promised summary was not found among them. As described in Chapter 53, after some failed attempts by others to produce the summary, a new, unnamed author took up the task, not by their own volition but through what they perceived as the grace and inspiration of the Guru.
