Britain's former 'first lady' Sarah Brown is to reveal all about her life at Downing Street life in a memoir.
Mum-of-two Sarah shared the news on Twitter at the weekend: "Agreed to a book - working title Behind the Black Door - so chained to laptop from Monday."
The former PR executive already has plenty of potential readers with over one million people following her regular updates on the microblogging site.
Publisher Ebury says that the book - due to be out next year - will "reflect moving from a successful career (in PR) to being an international charity campaigner; of balancing school plays and state visits; of being married to someone who becomes Prime Minister".
