The Moneypenny Diaries is a series of novels and short stories chronicling the life of Miss Moneypenny, M’s personal secretary in Ian Fleming’s James Bond series; it is considered an official spin-off of the Bond books. The diaries are penned by Samantha Weinberg under the pseudonym Kate Westbrook, who is depicted as the “editor.” The first installment of the trilogy, subtitled Guardian Angel, was released in October 2005 in the UK. A second volume, subtitled Secret Servant was released in November 2006 in the UK. A third volume, subtitled Final Fling was released in July 2008.

The novels had originally been touted as the secret journal of a “real” Miss Moneypenny and that James Bond was a possible pseudonym for a genuine intelligence officer, an idea shared by John Pearson’s earlier biography, James Bond: The Authorised Biography of 007. The publisher, John Murray, admitted in August 2005 that the books were a spoof after an investigation by the Sunday Times of London. Ian Fleming Publications, who had previously refused to comment as to whether the book was authorised, officially confirmed the book was and always had been a project by them on the day of the book’s publication.
