14th century Yorkshire: the time of Chaucer. Has Peregrine been broken? Injured in an attack by old adversaries, Father Peregrine transforms from a steely, articulate, impressive leader into a humbled, crippled, wise mentor. Relying on the kindness of his fellow monks, the fiercely independent, hawkish abbot begins to regain his feet. But he faces a fresh challenge. The Augustinian Priory of St Dunstan lies three days' ride to the southwest, the domain of Prior William, whose calculating self-interest makes enemies everywhere. When he and Peregrine cross swords over a matter of justice masked as doctrine, will ruthlessness triumph over integrity?
