Vappala Balachandran was a formidable presence in R&AW. He served as Chief of Staff to arguably two of the most powerful Chiefs of the Organisation after its founder, Rameshwar Nath Kao and held several other sensitive positions before retiring as Special Secretary. He belongs to the rare breed of officers who ungrudgingly shed the trappings of high-profile law-enforcement work and embraced the anonymity of the foreign intelligence profession. In retirement, he has been a prolific author and commentator on national security affairs. His latest book, “Intelligence Over Centuries” is a fascinating tour de horizon of the world’s second-oldest profession.
