Known as the Black Tiger in the intelligence agencies of India, Ravindra Kaushik was sent to Pakistan as a double agent at the age of 22. As Nabi Ahmed Shakir, Kaushik was given a new identity and sent into Pakistan in 1975. Taking up a family and a law degree in Pakistan, he was fully internalized when the military rule came to Pakistan. His next step was to become part of the army and know the core planning strategies of the military regime. Kaushik's secrets are considered to have changed the course of wars between India and Pakistan at this point of time, until his arrest.
