Holy Spy

In London's smoky taverns, a conspiracy is brewing: a group of wealthy young Catholic dissidents plot to assassinate Elizabeth, free Mary Queen of Scots - and open England to Spanish invasion. But the conspirators have been infiltrated by Sir Francis Walsingham's top intelligencer, John Shakespeare.

Revenger

England and Spain are at war, yet there is peril at home, too. The death of her trusted spymaster Sir Francis Walsingham has left Queen Elizabeth vulnerable. Conspiracies multiply. The quiet life of John Shakespeare is shattered by a summons from Robert Cecil.

The Heretics

England may have survived the Armada threat of 1588, but when Spanish galleys land troops in Cornwall on a lightning raid seven years later, is it a dry-run for a new invasion? Revenge for the sacking of Spanish shipping and ports? A warning shot to Drake and Hawkins?

Prince

Spring 1593. England is a powder keg of rumour and fear. Plague rages, famine is rife, the ageing Queen's couriers scheme: Elizabeth's Golden Age is truly tarnished. Meanwhile Spain watches and waits - and plots. Into this turmoil a small cart clatters through the streets of London, carrying a deadly load.

Martyr

England is close to war. Within days the axe could fall on the neck of Mary Queen of Scots, and Spain is already gathering a battle fleet to avenge her. Tensions in Elizabeth I's government are at breaking point.

Traitor

The Elizabethan navy has a secret weapon: an optical instrument so powerful it gives England unassailable superiority at sea. Spain will stop at nothing to steal it and seize the two men who understand its secrets - its operative William Ivory, known as the 'Queen's Eye', and its inventor, the maverick magician Dr Dee.
