From publisher blurb: Henry Denny, the leaseholder of Waltham manor, sends word of a monstrous threat harrowing travellers passing through Waltham Forest. John Dee sends the Agents to the market town of Waltham Abbey to investigate. As one of the favoured hunting grounds of the Queen, the Agents must resolve the matter with haste—who would dare to disappoint Her Majesty?
