Colin Hay returns home to Wales to reconcile with the father he blames for his mother's death. But he finds Sir Stephen in the arms of a bewitching young woman with designs on more than a place in Sir Stephen's bed. Belle covets the ancient olivewood drinking bowl that Colin brought with him when the abbey at Glastonbury was closed by King Henry VIII. Yet the cup, which once showed such supernatural power that some whispered it was the Holy Grail, now lies cold and empty in Colin's hands. Were the glorious promises of God's presence nothing more than a dream?
