All the Queen’s Men by SJ Bennett
In this sequel to the delightful mystery The Windsor Knot, Queen Elizabeth takes center stage at Buckingham Palace, where the atmosphere in the autumn of 2016 is a bit darker than in the first book. The Queen has been secretly sleuthing with the aid of her assistant private secretaries for years. A few female staff members have been receiving poison pen letters, including her new assistant private secretary, Rozie Oshodi. One of them is found dead by the pool at Buckingham Palace, apparently accidentally. Brexit has passed, and the palace needs expensive renovations. The Queen discovers a painting of her former royal yacht at a Navy exhibition, and tasks Rozie with investigating how it ever left the palace. Rozie explores tunnels beneath the palace, and in the end, others get the credit for solving the mystery. I will definitely read the next book, and hope the Queen and Rozie get to spend more time together, perhaps at Sandringham or Balmoral, and enjoy the scenery even more than at Windsor Castle.
