Through the wet spring of 1369 a pilgrimage wends its way to the sacred city of St David's. Owen Archer, ex-soldier and sometime spy, accompanies the party to recruit archers for the Duke of Lancaster, who prepares to fight the French. But he and Geoffrey Chaucer have another, covert, mission: to ascertain whether the Duke's steward at Cydweli is betraying him to Welsh rebels.

Trouble precedes them: a body in the Duke's livery is left at the city gates. And when Owen rides on to Cydweli he finds the household of the steward and his beautiful young wife rocked by the theft of money from the exchequer and riven by tension, culminating in another violent attack. He must work fast to investigate charges of treachery, infidelity and murder if he is to prevent further deaths.

Political skullduggery, passion and ambition clash in this intriguing, evocative and compelling novel which vividly conjures up the medieval world.
