January 1144. Hugh Bradecote does not want his betrothed heading off on pilgrimage to the shrine of St Eadgyth at Polesworth, but the Archbishop of Canterbury's envoy and his entourage of monks seem Heaven sent as escorts, right up until they are captured by a renegade who wants his forger out of the lord Sheriff's cells; a renegade who loathes the Benedictines, and kills for pleasure. Against a backdrop of a hard winter and even a frozen River Severn, Bradecote and Catchpoll are struggling to rescue the clerics, and Christina, before a psychopath does his worst, the lord Sheriff loses patience, and Bradecote cracks under the pressure.
