At Buckingham Palace, the autumn of 2016 presages uncertain times. The Queen must deal with the fallout from the Brexit referendum, a new female prime minister, and a tumultuous election in the United States—yet these prove to be the least of her worries when a staff member is found dead beside the palace swimming pool. Is it truly the result of a tragic accident, as the police think, or is something more sinister going on? Meanwhile, her assistant private secretary, Rozie Oshodi, is on the trail of a favorite painting that once hung outside the Queen's bedroom and appears to have been misappropriated by the Royal Navy. And a series of disturbing anonymous letters have begun circulating in the palace. The Queen's courtiers think they have it all 'under control', but Her Majesty is not so sure. After all, though the staff and public may not be aware, she is the keenest sleuth among them. Sometimes, it takes a Queen's eye to see connections where no one else can.
