being exiled (and thus forced to distance himself from his mistress), the knight, once the lord has promised to keep his secret, reveals to his lord where his heart truly lies, thus violating his promise to his mistress. The Duke reveals the truth of the knight's love to his wife, trusting her to keep the secret; but, at the feast of Pentecoste, the Duchess makes a cruel inside joke to the Châtelaine about her lover and her "well-trained dog". The Châtelaine realizes her lover has not kept his promise and she dies in despair. The knight discovers her body and kills himself. The Duke finds both bodies, and exacts vengeance on his wife by killing her with the knight's sword, and then becomes a knight Templar. Notes References Hasenohr, Geneviève and Michel Zink, eds.
