In the city of Nantes, in the year 1440, a woman hurries through the cobblestoned streets. Her world of faith, loyalty, and family is buckling under the weight of her suspicions about a dead child…and others who may have met the same fate—all at the hands of the same killer—the infamous Gilles de Rais. Soon Guillemette le Drappißere, companion to the Bishop of Nantes, is investigating the young nobleman she helped raise from infancy. To unravel the truth, Guillemette must enter a dark realm of power, perversion, bloodlust—and bring to it the unforgiving light of the church she serves.
