Queen Guinevere, trying to head off a rush to judgment, secures a promise from the king to let her be arbiter in the accused knight's case and sends the young man on a quest to discover what women most desire. The Knight's Riddle is a fast-paced mystery in King Arthur's mythic court of Camelot, set (like the original Arthurian romances) in the high Middle Ages, and narrated by the young squire Gildas, whose knightly ambitions revolve solely around his love of the beautiful Rosemounde.
