Dame Stella Rimington, DCB (born 13 May 1935) is a British author and former Director General of MI5, a position she held from 1992 to 1996. She was the first female DG of MI5, and the first DG whose name was publicised on appointment. In 1993, Stella Rimington became the first DG of MI5 to pose openly for cameras at the launch of a brochure outlining the organisation's activities.
Rimington published her memoirs, entitled Open Secret, in 2001. In July 2004, her first novel, At Risk, about a female intelligence officer, was published. Her other novels are Secret Asset (August 2006), Illegal Action (August 2007), Dead Line (October 2008), Present Danger (September 2009), and Rip Tide (July 2011). Her novels are part of a tradition of "insider" spy fiction written by former spies in the U.K., especially in MI5, going back to John Bingham, 7th Baron Clanmorris, John LeCarre, and Ted Allbeury, among others
