Chevalier

King Edward invites his barons to a 'Round Table' tournament in the spirit of King Arthur ... only to find a murderer lurks among them.
July 1284. King Edward has invited the nobility of England, Ireland, and Scotland to Nefyn, one of the most remote spots in Wales, for a Round Table—a tournament as in the tales of King Arthur to celebrate Edward's victory over the Welsh and his ascension to Arthur's throne.
Not everyone sees the tournament as a friendly competition, however, and in short order, Rhys and Catrin are called to investigate the death of a knight in the retinue of the Earl of Gloucester. But just as in King Arthur's court, malice and treason lurk beneath the surface, so when murder turns to treachery, it is up to Catrin and Rhys to separate fact from fiction in Chevalier, the second book in The Welsh Guard Mysteries.
