December, 1142. A brother of Shrewsbury Abbey suffers a fall that almost kills him. He makes a shocking deathbed confession to Brother Cadfael. When the man recovers Cadfael accompanies him on an arduous journey to redeem his past sins.

In the summer of 1143, William of Lythwood arrives at the Benedictine Abbey of St. Peter and St. Paul, but it is not a joyous occasion—he’s come back from his pilgrimage in a coffin. William’s body is accompanied by his young attendant Elave, whose mission is to secure a burial place for his master on the abbey grounds, despite William’s having once been reprimanded for heretical views. An already difficult task is complicated when Elave drunkenly expresses his own heretical opinions, and capital charges are filed. When a violent death follows, Sheriff Hugh Beringar taps his friend Brother Cadfael for help. The mystery that unfolds grows deeper thanks to a mysterious and marvelous treasure chest in Elave’s care.

At the height of the hot summer of 1144, a lucky hit by one of King Stephen's archers rids the Fen country of Geoffrey de Mandeville, Earl of Essex, who has amassed his castles and gold by robbing rich and poor alike. Thus, the Benedictine abbey at Ramsey, long used as a den for Geoffrey's raggle-taggle marauders, is returned in a thoroughly ruined state to the good brothers of that order. The news comes to Brother Cadfael or the Abbey of St. Peter and St. Paul in Shrewsbury in the person of the dour, raw-boned Brother Herluin who is soliciting funds and aid to restore Ramsey Abbey to its former splendor. Of much more interest to Cadfael is Herluin's companion, Brother Tutilo, a slightly built lad with a guileless face surrounded by a profusion of brown curls. But Brother Cadfael, long a shrewd judge of character, notes on that brow an intelligence that bespeaks more of mischief than innocence, and he muses that this Brother Tutilo bears watching. The arrival of a French troubadour, his servant, and a girl with the voice of an angel gives Cadfael a feeling in his wise bones that something is about to happen. It does. The late autumn rains bring flood waters right to the altar where the abbey's most precious possession reposes - the bones of Saint Winifred. Only Brother Cadfael knows that moving the holy relic can expose a long hidden secret. He never envisions that the results of disinterment will be the theft of the cherished bones...and murder. Suspicion quickly falls on a guilty-looking Brother Tutilo. But did he do it?

A savage murder interrupts an ill-fated marriage set to take place at Brother Cadfael's abbey, leaving the monk with a terrible mystery to solve. The key to the killing is hidden among the inhabitants of the Saint Giles leper colony, and Brother Cadfael must ferret out a sickness not of the body, but of a twisted mind.

The fourth anniversary of the transfer of Saint Winifred's bones to the Abbey at Shrewsbury is a time of celebration for the 12th-century pilgrims gathering from far and wide. In distant Winchester, however, a knight has been murdered. Could it be because he was a supporter of the Empress Maud, one of numerous pretenders to the throne? It's up to herbalist, sleuth, and Benedictine monk Brother Cadfael to track down the killer in the pious throng.

In October of 1142, a local landlord gives the Potter's Field to the local clergy. The monks begin to plow it, and the blades turn up the long tresses of a young woman, dead over a year. Then the arrival of a novice who fled from an abbey ravaged by civil war in East Anglia complicates life even further for Brother Cadfael.

In a mild December in the year of our Lord 1141, a new priest comes to the parishioners of the Foregate outside the Abbey of Saint Peter and Saint Paul. Father Ailnoth brings with him a housekeeper and her nephew—and a disposition that invites murder. Brother Cadfael quickly sees that Father Ailnoth is a harsh man who, striding along in his black cassock, looks like a doomsaying raven. The housekeeper’s nephew, Benet, is quite different—a smiling lad, a hard worker in Cadfael’s herb garden, but, as Brother Cadfael soon discovers, an impostor. And when Ailnoth is found drowned, suspicion falls on Benet, though many in the Foregate had cause to want this priest dead. Now Brother Cadfael is gathering clues along with his medicinals to treat a case of unholy passions, tragic politics, and perhaps divine intervention.

In honor of her husband, young, beautiful, and wealthy widow Judith Perle donates a house to the Abbey at Shrewsbury - for the annual rent of one white rose. Judith has no shortage of suitors, and if she remarries, her dowry would be all the greater if the house were returned due to non-payment of rent. So when a priest charged with delivering the rose is found murdered, and the rose bush is found hacked to pieces, Brother Cadfael finds he must root out a killer.

In the summer of 1144, a strange calm has settled over England. The armies of King Stephen and the Empress Maud, the two royal cousins contending for the throne, have temporarily exhausted each other. On the whole, Brother Cadfael considers peace a blessing. Still, a little excitement never comes amiss to a former soldier, and Cadfael is delighted to accompany a friend on a mission of diplomacy to his native Wales. But shortly after their arrival, the two monks are caught up in another royal feud. The Welsh prince Owain Gwynedd has banished his brother Cadwaladr, accusing him of the treacherous murder of an ally. The reckless Cadwaladr has retaliated by landing an army of Danish mercenaries, poised to invade Wales. As the two armies teeter on the brink of bloody civil war, Cadfael is captured by the Danes and must navigate the brotherly quarrel that threatens to plunge an entire kingdom into chaos.
