On Duty with the Queen by Dickie Arbiter
Published July 10, 2017
At the end of this book, Dickie Arbiter says this was intended to be a professional memoir of a difficult period in the monarchy that he was on hand to witness, but gradually it became something more personal. That shines through during the whole book. It's about his job in the press room of Buckingham Palace during some very difficult times - the death of Princess Diana in particular.
