A severed hand is found washed up on a beach next to the Queen's estate at Sandringham.
Elizabeth has become quite accustomed to solving even the most complex of murders. And though she quickly identifies the 70-year-old victim, Edward St Cyr, from his signet ring, the search for his killer is not so straightforward.
St Cyr led an unconventional, often controversial life, making many enemies along the way in the quiet, rural world of North Norfolk, where everyone knows each other's business. But when a second man is found dead, and a prominent local woman is nearly killed in a hit-and-run, the mystery takes an even darker turn.
With the Christmas break coming to an end, the Queen and her trusted assistant Rozie must race to discover how the pieces of the puzzle fit together. Or the next victim may be found even closer to home.
