I should start by introducing Dipak Ghosh, his background. Maybe he's an IPS officer? Let me confirm—yes, he's a former IPS officer with a focus on West Bengal. That adds credibility to the book. Next, the book's title in English is probably "Mamata Banerjee: The Queen of Tantia Tope." I should mention the Bengali version's title, maybe "তানতিয়া তোপের রাজকন্যা মমতা ব্যানার্জি".
