Mavis was sent to Bletchley Park, the centre of code-breaking operations which were crucial to the allied victory in the war. Here she met and married her husband Keith in 1942, and together they kept the secret of their war-time intelligence work, forbidden like everyone else involved from speaking about it for the next 30 years.
Since her involvement at Bletchley became known, Mavis has been in great demand from researchers wanting inside information. Actress Kate Winslet wanted to know what it was like to be a woman at Bletchley for her part in the film Enigma. Most recently Mavis has been helping researchers to establish how much of the action in Ian Fleming’s James Bond novels was based on his career in naval intelligence.
