The Knight's Riddle — Jay Ruud

When a disheveled young woman walks into Arthur's court demanding justice, declaring she has been raped by a knight of the Round Table, Arthur vows that the culprit will be punished. Gildas of Cornwall, now squire to Sir Gareth, has his own problems: His beloved Rosemounde has been betrothed to another knight. When Rosemounde's new fiancé is accused of the vicious crime, Gildas must enlist the aid of his old mentor, Merlin, to prove the innocence of the man to whom Gildas's own love belongs.

The Knight's Riddle is a fast-paced mystery set in King Arthur's mythic court of Camelot, imagined in the high Middle Ages, and narrated by the young squire Gildas, whose knightly ambitions revolve solely around his love of the beautiful Rosemounde.
