Milicent Jessie Eleanor Bagot, CBE (28 March 1907 – 26 May 2006) was a British intelligence officer. She was the purported model for the character Connie Sachs, the eccentric Sovietology expert who appeared in John le Carré's novels Tinker, Tailor, Soldier, Spy, The Honourable Schoolboy and Smiley's People, and the character of Muriel Edge in two of the 'Troy' novels by John Lawton – Black Out and Old Flames. Early life and education Milicent Jessie Eleanor Bagot was born on 28 March 1907 to Ethel (née Garratt) (d. 1944) and Cecil Villiers Bagot (1865–1940), MA a London solicitor. She was the paternal great-great-granddaughter of William Bagot, 1st Baron Bagot, 6th Baronet and the maternal granddaughter of Jesse Garratt, of Wateringbury, Kent. Bagot was educated at Putney High School and Lady Margaret Hall, Oxford (MA), where she took a Class IV in Classical Moderations in 1927. Career Bagot began work as a temporary registry clerk with the Metropolitan Police Special Branch in 1929, at the age of 22. She entered the Ministry of Defence from Scotland Yard as a secretary in 1931, when her section was transferred to MI5. The move resulted in a forced significant pay cut of £8 a year, a not inconsiderable sum at the time. She went on to work for both MI5 and MI6. During her long career Bagot became one of the security service's principal experts on Soviet Communism. She was the first person to warn MI5 that Kim Philby, MI6 officer and Soviet KGB double agent, had been a member of the Communist party. Philby's denial of this fact led to his eventual resignation from MI6, and his flight to Moscow. Bagot also wrote a definitive account of the 1924 Zinoviev Affair in which a forged letter purported to be from Grigory Zinoviev, president of the executive committee of the Comintern, urged the British working class to rise up in an armed insurrection. The publication of the letter is thought by some to have had an effect on the subsequent electoral defeat of the Ramsay MacDonald-led Labour Government. It has also been suggested that MI5 or MI6 may have been involved in leaking the forged letter, which probably originated from anti-Soviet emigrants living in Latvia. During the Second World War Bagot worked as a clerk in the Registry and the counter subversion section, at Wormwood Scrubs and later at Blenheim Palace. She later spent
