Catherine suggested to the young chamberwoman, who was at that time with child, that she should deceive the doctor by representing that certain signs of her own condition really belonged to the sick woman, so that he, deceived by the false indications, should be compelled to admit to Charles of Durazzo that his mother was guilty and dishonoured.

The Count of Terlizzi, who ever since he had taken part in the regicide trembled in fear of discovery, had nothing to oppose to the empress's desire, and Dona Cancha, whose head was as light as her heart was corrupt, seized with a foolish gaiety on any chance of taking her revenge on the prudery of the only princess of the blood who led a pure life at a court that was renowned for its depravity.

Once assured that her accomplices would be prudent and obedient, Catherine began to spread abroad certain vague and dubious but terribly serious rumours, only needing proof, and soon after the cruel accusation was started it was repeated again and again in confidence, until it reached the ears of Charles.
At this amazing revelation the duke was seized with a fit of trembling.
He sent instantly for the doctor, and asked imperiously what was the cause of his mother's malady.

The doctor turned pale and stammered; but when Charles grew threatening he admitted that he had certain grounds for suspecting that the duchess was enceinte, but as he might easily have been deceived the first time, he would make a second investigation before pronouncing his opinion in so serious a matter.

The next day, as the doctor came out of the bedroom, the duke met him, and interrogating him with an agonised gesture, could only judge by the silence that his fears were too well confirmed.
