The Windsor Knot (Her Majesty the Queen Investigates #1)

I love the idea of Queen Elizabeth sleuthing behind the scenes! As charmingly and convincingly portrayed by SJ Bennett, the Queen is an astute observer whose decades of experience serve her well in this role. When a Russian pianist is found dead at Windsor Castle, the new head of MI5 muddles the case and makes the mistake of treating the Queen like his doddering granny. It’s up to the Queen to secretly and skillfully line up the pieces of the puzzle for MI5 to solve.
