On his recovery, he determines to make a journey of expiation, with Cadfael as his sole companion. It is an arduous journey, physically and emotionally, and one that leads to some shocking discoveries.

A despised priest is drowned in a pond in this medieval mystery filled with “lively period detail” (Kirkus Reviews). 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.

Strangers seek refuge at the abbey as floodwaters rise, a body falls, and a relic vanishes—in this “top drawer” mystery featuring the twelfth-century monk (Chicago Sun-Times) In the chill, rainy autumn of 1144, two groups of visitors seek the hospitality of the Abbey of St. Peter and St. Paul, and Brother Cadfael fears trouble has come in with them.

The second group, a ribald French troubadour, his servant, and a girl with the voice of an angel, seems to Brother Cadfael a catalyst for disaster. All of Cadfael’s fears become manifest as rising floodwaters endanger the abbey’s most sacred relic, the remains of Saint Winifred. When the bones disappear and a dead body is found, Brother Cadfael knows carnal and spiritual intrigues are afoot. Now, in a world that believes in signs and miracles, Brother Cadfael needs his prayers answered—as well as some heavenly guidance to crucial clues—to catch a killer hell-bent on murder.
