The Moneypenny Diaries: Guardian Angel is the first in a planned trilogy of novels chronicling the life of Miss Moneypenny, M's personal secretary in Ian Fleming's James Bond series. The diaries were authored by Samantha Weinberg under the pseudonym Kate Westbrook, who is depicted as the book's editor. The first installment, subtitled Guardian Angel was released in the United Kingdom on October 10, 2005 by John Murray publishers. A United States edition was published by Thomas Dunne Books on May 13, 2008 , although this edition has no subtitle.
Weinberg is the first woman to write an officially licensed James Bond-related novel.
The trilogy 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, the idea of which was perhaps influenced similarly to John Pearson's 1973 authorised biography of James Bond. James Bond: The Authorised Biography of 007 was based on the obituary in Ian Fleming's You Only Live Twice in which Fleming hints that Bond is perhaps a real man.
An investigation by The Sunday Times into whether or not The Moneypenny Diaries were in some way real forced John Murray publishers to admit that the novel was in fact a "spoof". Prior to the admission, Kate Westbrook was said to be niece of the "real" Jane Moneypenny and that the diaries were discovered after her death in 1990. It was also claimed that Westbrook was a fellow of Trinity College, Cambridge, however, the college replied stating no such person was in employment there. In an interview, Weinberg revealed that the 'Kate Westbrook' subterfuge stretched as far as her wearing a wig and coloured contact lenses for media interviews and at the launch party.
The novel was officially recognized as an authorised book from Ian Fleming Publications on the day of the book's publication in the UK, October 10, 2005. A side-effect of the deception resulted in a delay in this book finding an American publisher.
