March 1367. Edward III wants William of Wykeham confirmed as Bishop of Winchester, but papal resistance threatens the appointment. Owen Archer leads a delegation to Fountains Abbey to seek support from influential Cistercian abbots, while his old comrade Ned Townley accompanies a second party to Rievaulx under suspicion connected with an earlier death.
A friar and Townley vanish after news arrives of a murder at Windsor, turning an ecclesiastical mission into a search for conspirators. Owen appeals to Archbishop Thoresby at court and is drawn into the dangerous circle surrounding Alice Perrers, where personal ambition, royal patronage and hidden loyalties make it difficult to tell who is protecting the king's candidate and who is exploiting the dispute.
