November 1262 is an unlikely season for war. But war nonetheless is coming to the March, the wild borderland between England and Wales. Not the war that most fear between the supporters of the King and the rebellious barons uniting around Simon de Montfort, but with Llywelyn ap Gruffydd, the Welsh warlord who styles himself Prince of Wales and who has united the fractious tribes of his land against the English.
The English are uncertain, however, where and when the blow will fall. So, Sir Geoffrey Randall, coroner of Herefordshire, dispatches his deputy, the impoverished knight Stephen Attebrook, to the border town of Clun to make contact with a spy in order to learn Llywelyn’s plans.
At the same time, Randall directs Attebrook to investigate the murder of a monk found dead in his bed at the Augustine priory of St. George at Clun.
The assignment casts Attebrook into the middle of a desperate feud between the priory and the lord of Clun and reveals a forbidden love that can only result in suffering and death.
