Prime Minister Narendra Modi has taken it upon himself to unravel one of modern India's greatest mysteries, the fate of Netaji Subhas Chandra Bose, from secret files held by his government. Three days after an India Today Group exclusive revealed a 20-year surveillance on the Bose family, Modi assured Netaji's Grand nephew Surya Kumar Bose of his "personal interest in the matter". And the venue was, quite appropriately, Berlin where Bose surfaced after escaping from India in 1941 to launch an armed struggle for freedom."The truth must come out," the Prime Minister told the Germany-based businessman soon after accepting a petition on behalf of the freedom fighter's family. It was no empty assurance. Barely 48 hours later, the government announced a committee headed by the Cabinet secretary and comprising experts from the Intelligence Bureau (IB), Research and Analysis Wing and the Ministry of External Affairs (MEA) to examine the Official Secrets Act in the context of the Netaji's files.
