This is the first definitive biography of arguably India’s most influential and powerful civil servant: P.N. Haksar, Indira Gandhi’s alter ego during her period of glory.

Educated in the sciences and trained in law, Haksar was a diplomat by profession and a communist-turned-democratic socialist by conviction. He had known Indira Gandhi from their student days in London in the late-1930s, even though family links predated this friendship. They kept in touch, and in May 1967, she plucked him out of his diplomatic career and appointed him secretary in the prime minister’s Secretariat. This is when he emerged as her ideological beacon and moral compass, playing a pivotal role in her much-heralded achievements including the nationalization of banks, abolition of privy purses and princely privileges, the Indo-Soviet Treaty, the creation of Bangladesh, rapprochement with Sheikh Abdullah, the Simla and New Delhi Agreements with Pakistan, the emergence of the country as an agricultural, space and nuclear power and, later, the integration of Sikkim with India.
