The prolific author Sudeep Chakravarti’s 10th book, Fallen City, is about Delhi, where two children, Geeta and Sanjay, were brutally murdered in 1978. He places the crime in a socio-political context. Chakravarti’s own life is as interesting as his work and he has just emerged after three years in Dhaka, where he set up a South Asia study department at a university. In an interview with Frontline, he speaks about his latest book, Bangladesh’s transformation over the years, the ouster of Sheikh Hasina, the recent spate of violence against the nation’s Hindus, the protests in Kolkata, and more.
