Stella Rimington first joined Britain’s Security Service (MI5) part-time in 1965, while she was in India accompanying her husband on a posting to New Delhi. She became a full-time employee on her return to the U.K. During her career with MI5, she worked in all the main fields of the Service: counter-subversion, counter-espionage and counter-terrorism becoming, successively, Director of all three branches. She was appointed Director-General in 1992 -- the first woman to hold the post and the first Director-General whose name was publicly announced. During her tenure, she pursued a policy of greater openness for MI5, giving several public lectures and publishing a booklet about the service.
