York, October 1376. Owen Archer is summoned after a stripped and bloodied corpse is found on the road north of the city. The death may be connected to an attack on a carter transporting stone to St Clement's Priory, whose labourers remained to fight and have since disappeared.
At first Owen suspects that the arrival of the politically isolated Bishop William of Wykeham has provoked the violence. Evidence instead points towards a disciplined adversary from Owen's earlier military life, transforming the inquiry into a struggle to identify the missing men and the killer before an old enemy can reach Lucie, their children and everything Owen has built in York.
