One of the most famous allegations in the book is that during her 25-day hunger strike in 2006 (protesting land acquisition in Singur), the TMC leader was allegedly consuming chocolates and sandwiches behind closed doors.

His notable assignments included serving as the SDO of Siliguri during the 1967 Naxalbari uprising and as the District Magistrate (DM) of Nadia during the 1971 Bangladesh Liberation War.

This book, along with its English counterpart Mamata Banerjee: As I Have Known Her (The Goddess That Failed) , has become a cornerstone of political debate in West Bengal for its unfiltered and critical portrayal of Chief Minister Mamata Banerjee.

The book includes sensational claims regarding Banerjee's private life, including allegations of a secret marriage to an advocate named Ranjan Ghosh. These claims remain entirely unsubstantiated by official records, and Banerjee has always maintained she is unmarried.
