To the guests at the mourning feast for Thomas Chaucer, the last words of Sir Clement Sharpe had been enough to damn him in the eyes of God. Detested by all who knew him, his final blasphemy had turned even God's anger against him and his death would be a lesson well-remembered. None among them would ever forget the sight of God striking down a sinning man, and each would keep in their heart the need to honor God's charity and love in all the hours of their lives. But the crafty Dame Frevisse and cunning Bishop Beaufort suspect that there may be an all-too-mortal hand at work in Sir Clement's death. If their suspicions can be proved, then the only lesson to be learned is the bleakest secret of the blackest heart.
