Helen O'Brien

Helen O'Brien (née Elena Constantinescu, 14 December 1925 – 16 September 2005) was a British spy and nightclub owner. The daughter of a landowner and an aristocrat, she escaped advancing Russians on the King's racehorse, fled the communists in Romania, and in 1953 co-founded what the press dubbed as a club with the most daring West London floor performances of its era, where she worked as a spy for the UK's MI5 and MI6.
