This was another source of uneasiness to the Queen-mother, who apprehended, from the pertinacity with which Marguerite clung to her husband, that she would exert all her influence to effect an understanding between the two brothers-in-law which could not fail to prove fatal to the interests of the Duc d'Anjou, who, in the event of the decease of Charles IX, was the rightful heir to the throne. Nor was that decease a mere matter of idle speculation, for the health of the King, always feeble and uncertain, had failed more than ever since the fatal night of the 24th of August; and he had even confessed to Ambroise Paré,[9] his body-surgeon, that his dreams were haunted by the spectres of his victims, and that he consequently shrank from the sleep which was so essential to his existence. The Duc d'Anjou meanwhile was absent at the siege of Rochelle, while his brother, d'Alençon, was about the person of the dying monarch, and had made himself eminently popular among the citizens of Paris. The crisis was an alarming one; but it was still destined to appear even more perilous, for, to the consternation of Catherine, intelligence at this period reached the Court that the Polish nation had elected the Duc d'Anjou as their King, and that their ambassadors were about to visit France in order to tender him the crown. In vain did she represent to Charles the impolicy of suffering a warlike prince like Henri d'Anjou to abandon his country for a foreign throne, and urge him to replace the elder by the younger brother, alleging that so long as the Polish people could see a prince of the blood-royal of France at the head of their nation, they would care little whether he were called Henry or Francis; the King refused to countenance such a substitution. He had long been jealous of the military renown of the Duc d'Anjou; while he was also perfectly aware of the anxiety with which both the Queen-mother and the Prince himself looked forward to his own death, in order that Henry might succeed him; and he consequently issued a command that the sovereign-elect should immediately repair to Paris to receive at the hands of the foreign delegates the crown which they were about to offer to him. The summons was obeyed. The ambassadors, who duly arrived, were magnificently received; Henri d'Anjou was declared King of Poland; and, finally, he found himself compelled to depart for his own kingdom. Unfortunately for Marguerite, she had not sufficient self-control to conceal the joy with which she saw the immediate succession to the French throne thus transferred to her favourite brother; and her evident delight so exasperated the Queen-mother, that she communicated to Charles the suspicions which she herself entertained of the treachery of the Princess; but the King, worn down by both physical and mental suffering, treated her warnings with indifference, and she was consequently compelled to await with patience the progress of events.
