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. With a second Armada threatened, intelligencer John Shakespeare is sent north to escort Dr Dee to safety. But his mission is far from straightforward. Dee's host, the Earl of Derby, cousin to Elizabeth, is dying in agony, apparently poisoned. Who wants him dead and why? What lies behind the lynching of the recusant priest Father Matthew Lamb? And what exactly is the connection between these events and the mysterious and beautiful Lady Eliska? While Shakespeare attempts to untangle a plot that points to treachery at the very highest reaches of government, he also faces serious accusations far closer to home. With so much at stake, must he choose between family and his duty to Queen and country? Moving from the Catholic heartlands of Lancashire to a vagabond camp in the heart of England, and from the deck of Admiral Frobisher's flagship off the Brittany coast to the secret meetings of Elizabeth's closest associates, Traitor is award-winning writer Rory Clements' most intriguing and compelling novel to date.

From Rory Clements, winner of the Ellis Peters Historical Fiction Award, comes THE HERETICS, the fifth in his acclaimed John Shakespeare Elizabethan mystery series. 'Does for Elizabeth's reign what C. J. Sansom does for Henry VIII's' Sunday Times 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? Or is there, perhaps, a more sinister motive? The Queen is speechless with rage.But as intelligencer John Shakespeare tries to get a grip on events, one by one his network of spies is horribly murdered. What has all this to do with Thomasyn Jade, a girl driven to the edge of madness by the foul rituals of exorcism? And what is the link to a group of priests held prisoner in bleak Wisbech Castle? From the pain-wracked torture rooms of the Inquisition in Seville to the marshy wastes of fenland, from the wild coasts of Cornwall to the sweat and sawdust of the Elizabethan playhouses, and from the condemned cell at Newgate to the devilish fantasies of a fanatic, THE HERETICS builds to a terrifying climax that threatens the life of the Queen herself.
