To compel his cousin to make these two concessions, he added that if she should be so ill advised as to refuse either of them, he should hand over to justice the proofs of the crime and the names of the murderers.

Joan, bending beneath the weight of this new difficulty, could think of no way to avoid it; but Catherine, who alone was stout enough to fight this nephew of hers, insisted that they must strike at the Duke of Durazzo in his ambition and hopes, and tell him, to begin with--what was the fact--that the queen was pregnant.

If, in spite of this news, he persisted in his plans, she would find some means or other, she said, of causing trouble and discord in her nephew's family, and wounding him in his most intimate affections or closest interests, by publicly dishonouring him through his wife or his mother.
Charles smiled coldly when his aunt came to tell him from the queen that she was about to bring into the world an infant, Andre's posthumous child.

What importance could a babe yet unborn possibly have--as a fact, it lived only a few months--in the eyes of a man who with such admirable coolness got rid of people who stood in his wary, and that moreover by the hand of his own enemies?
He told the empress that the happy news she had condescended to bring him in person, far from diminishing his kindness towards his cousin, inspired him rather with more interest and goodwill; that consequently he reiterated his suggestion, and renewed his promise not to seek vengeance for his dear Andre, since in a certain sense the crime was not complete should a child be destined to survive; but in case of a refusal he declared himself inexorable.

He cleverly gave Catherine to understand that, as she had some interest herself in the prince's death, she ought for her own sake to persuade the queen to stop legal proceedings.
The empress seemed to be deeply impressed by her nephew's threatening attitude, and promised to do her best to persuade the queen to grant all he asked, on condition, however, that Charles should allow the necessary time for carrying through so delicate a business.
