Queen Elizabeth I is dying, and the King of England's oldest and bitterest enemy, Scotland, is poised to take the throne. With all her old allies and advisors dead, she turns to the only man she can trust: Henry Gresham. Gresham finds himself unwillingly dragged into the political manoeuvring that will decide England's next ruler. Involved in the race to be the first to tell James VI of Scotland that Elizabeth has chosen him as her successor, Gresham faces savage attacks on his home and those he loves.
