The delightfully clever mystery in which Queen Elizabeth II secretly solves a murder at Buckingham Palace, expertly narrated by Samantha Bond (Golden Eye, Tomorrow Never Dies, Die Another Day, Downton Abbey, The Queen and I, The Queen, Home Fires).

Queen Elizabeth II is having a royal nightmare.

A referendum divides the nation, a tumultuous election grips the United States - and the body of a staff member is found dead beside Buckingham Palace swimming pool.

Is it a tragic accident, as the police think? Or is something more sinister going on?

As Her Majesty looks for answers, her trusted assistant, Rozie, is on the trail of a treasured painting that once hung outside the queen's bedroom.

But when Rozie receives a threatening anonymous letter, Elizabeth knows dark forces are at work - and far too close to home. After all, though the staff and public may not realise it, she is the keenest sleuth among them. Sometimes, it takes a queen's eye to see connections where no one else can...
