Manawydan and Pryderi vs. the wife of Gwawl's friend Llywyt

Case description: Manawydan and Pryderi accuse the wife of their pal Gwawl of sabotaging their crops. When Manawydan tried to grow wheat, it was blighted—he found that a mouse army was destroying it, led by Gwawl's friend's wife in disguise!

Case status: Settled. Gwawl's BFF Lllwyt tests Manny to see if he's all there mentally, but Manawydan sees right through his tricks. In return for a good crop and Rhi and Pry being freed from imprisonment, Gwawl gets his wife back.
