Dorothy L. Sayers took her inspiration from a monk's account of the fire of 1174, and the subsequent rebuilding of Canterbury Cathedral Quire. She portrays William of Sens, the chosen architect, as eaten away by pride in his splendid work, unable to give glory to God for his achievement. Enacted in the presence of a group of graciously influential archangels, the play reveals the carelessness of some of the monks, resulting in the terrifying fall that cripples William. His agony brings him to repentance and gratitude before God, and finally to the renunciation of his role, leaving the completion of the rebuilding to others." -- Cover.
