The prince's tutor and the governess of the heiress had but to exchange one glance, icy, penetrating, plain to read: their looks met like lightning flashes of hatred and of vengeance.

The Catanese, who felt she was detected, lacked courage to fight this man in the open, and so conceived the hope of strengthening her tottering empire by the arts of corruption and debauchery.

She instilled by degrees into her pupil's mind the poison of vice, inflamed her youthful imagination with precocious desires, sowed in her heart the seeds of an unconquerable aversion for her husband, surrounded the poor child with abandoned women, and especially attached to her the beautiful and attractive Dona Cancha, who is branded by contemporary authors with the name of a courtesan; then summed up all these lessons in infamy by prostituting Joan to her own son.

The poor girl, polluted by sin before she knew what life was, threw her whole self into this first passion with all the ardour of youth, and loved Robert of Cabane so violently, so madly, that the Catanese congratulated herself on the success of her infamy, believing that she held her prey so fast in her toils that her victim would never attempt to escape them.
A year passed by before Joan, conquered by her infatuation, conceived the smallest suspicion of her lover's sincerity.

He, more ambitious than affectionate, found it easy to conceal his coldness under the cloak of a brotherly intimacy, of blind submission, and of unswerving devotion; perhaps he would have deceived his mistress for a longer time had not Bertrand of Artois fallen madly in love with Joan.
