From the author of The Time Traveller's Guide to Elizabethan England, now a major BBC 2 TV series, comes the next enthralling Elizabethan thriller.

September 1566. William Harley, Clarenceux King of Arms, lives quietly with his family in London, with a document in his possession that could destroy the state. The aged Lady Percy, Countess of Northumberland, has not given up trying to find it. Nor has she forgotten how he betrayed her and the Catholic cause - she has spent the last two years planning her revenge. But then eloquent and adventurous courtier, John Greystoke suddenly seems most concerned for Clarenceux's safety. And why, on behalf of the government, does Francis Walsingham have spies watching Clarenceux's house day and night? When his wife and his daughter go missing, Clarenceux finds himself on the run with his other young daughter, hunted by Lady Percy's agents. He knows he must finally destroy the document, even if it should cost him his life - but how can he, until he has reunited his family?
