Fuller was born in England on 7 March 1915, the posthumous and only child of an Indian Army officer. Brought up to think for herself by her mother, who was an artist, and a grandfather who was a retired Army doctor she early developed a wide field of interests. Following a short-lived career as a repertory actress she studied phonetics, linguistics and astronomy, and graduated with honours from the University of London. In the 1930s she became a member of the poetry circle of Victor Benjamin Neuburg, whose biography she wrote. Fuller was a friend of the Inayat Khan family. During the Second World War, she was employed by the British Postal Censorship Office in London. At the end of hostilities, she travelled extensively throughout Europe, interviewing various people connected with Noor's life. The resultant publication, Madeleine, published by Victor Gollancz Ltd. in 1952, was re-published in 1988 by East-West Publications in Rotterdam. This updated version contains some chapters that were removed from the original manuscript, such as an in-depth exploration of Tipu Sultan, Noor's ancestor. Following the book's publication, Fuller continued extensive research into the history of the wartime SOE French networks, interviewing many of the people involved – British and French, as well as Germans – in order to discover who was responsible for betraying Noor and her fellow agents. Her results were published in the 1958 book Double Webs. Until the publication of Shrabani Basu's Spy Princess: The Life of Noor Inayat Khan, Fuller's book was considered to be the definitive biography of Noor Inayat Khan. Fuller also wrote several other biographies, notably of Percy Bysshe Shelley, Algernon Charles Swinburne, Sir Francis Bacon, Victor Neuburg and a book detailing her theory of Jack the Ripper's true identity as Walter Richard Sickert, an English painter. Jean Overton Fuller's memoirs were published in 2007 by Michael Russell, Wilby, Norwich under the title Driven To It, An Autobiography. She died in Kettering on 8 April 2009 at the age of 94.
