All talk is of the End-time... and the dead are rising.

At the end of the sunless summer of 1560, black rumour shrouds the death of the one woman who stands between Lord Robert Dudley and marriage to the young Queen Elizabeth. Did Dudley's wife, Amy, die from an accidental fall in a deserted house, or was it murder? Even Dr John Dee, astrologer royal, adviser on the Hidden and one of Dudley's oldest friends, is uncertain. Then a rash promise to the Queen sends him to his family's old home on the Welsh Border in pursuit of the Wigmore Shewstone, a crystal credited with supernatural properties.

With Dee goes Robert Dudley, considered the most hated man in England. They travel with a London judge sent to try a sinister Welsh brigand with a legacy dating back to the Battle of Brynglas. After the battle, many of the English bodies were, according to legend, obscenely mutilated. Now, on the same haunted hill, another dead man has been found, similarly slashed.

Devious politics, small-town corruption, twisted religion and a brooding superstition leave John Dee isolated in the land of his father.
