Volume 6 in the Shardlake series.

With Henry VIII’s death imminent, Tudor England is on the precipice of change, with one woman holding the keys to its future. As the King’s Catholic and Protestant councillors fight for the right to control the government once it is taken over by Henry’s son, Prince Edward, then just eight years old, Matthew Shardlake is working on his biggest case yet. Queen Catherine Parr confides in him that a book she wrote in secret with a radically Protestant message has gone missing from her private chest and compels him to find it. As the country's future hangs in the balance, Shardlake and Jack Barak find themselves in the backstreets of London and the royal courts of Whitehall searching for the precious missing pages.
