After two miscarriages, the 12th Century sleuth Catherine LeVendeur and her Saxon husband travel to the shrine of St. James in Santiago de Compostela, Spain, to petition the saint for a child. On the way they encounter mad monks, not-so-penitent crusaders, and murder.

In 12th Century France, Catherine LaVendeur, the novice nun, is sent on an undercover mission by Mother Heloise, the abbess of the convent. She has to find the killer of a wealthy noblewoman. In this, Catherine is ably aided by her fiance, Edgar, a student of the monk, Peter Abelard. By the author of Death Comes As Epiphany.
