England is alone - a Protestant nation in a largely Catholic Europe. Then, 12 years into Elizabeth's reign, the pope declares her a heretic, which in the hearts of England's Catholics gives them permission to kill her. Queen Elizabeth looks to her spymaster William Cecil to stop the Catholic assassins getting through. Cecil establishes a huge espionage network - England's first secret service. His spies break Catholic conspiracies at home and abroad. Cecil's network is put on high alert by intelligence from a source in Catholic Europe. As a result he catches a courier carrying coded letters that lead Cecil to unravel a plot to assassinate Elizabeth and install her cousin Mary, Queen of Scots on the English throne.

Robert Cecil is the son of Elizabeth I's original spymaster. He has been groomed since birth to inherit his father's network but when he finally steps into his father's shoes, the queen's enemies are stronger than ever and Cecil must also watch his back. The Earl of Essex has established a rival network and is trying to oust Cecil as Elizabeth's spymaster. Essex is everything Cecil is not. Cecil is bent-backed and under five foot tall. Essex is an athlete and a war hero who flirts with the queen. But the two men have known each other since childhood. And now they are locked in a battle that is part court theatrical, but which is also a lethal spy war in which people die horrifically violent deaths. The stakes are huge. For the winner, untold power. For the loser a one-way trip to the scaffold.

King James of Scotland travels south to take the throne at the invitation of Robert Cecil. Meanwhile, John Gerard, a Catholic priest who has dedicated his life to the destruction of the Protestant state that developed in Elizabeth's England, has escaped and made contact with a splinter cell in the Catholic underground containing an extremist called Guy Fawkes, who has a plan to blow up parliament with the king inside. Cecil hears about the gunpowder plot, but is unaware of when and how they will strike, and his investigation is hampered as he's also trying to manage King James, who has a wildly ambitious idea of unifying Scotland and England in a new kingdom of Great Britain.
