This imprudent action soon became known at the court of Chilperic, and the ambitious Fredegonde hastened to turn it to her advantage. Merovee was heir to the throne of Chilperic. He was in her way, and had now given her a pretext for his removal. Chilperic, who seems to have been the weak slave of her designs, would have seized both Merovee and his bride but for the Austrasians, who demanded that their queen Brunehild should be restored to them, and enforced their demands with threats. She was surrendered; but Merovee, under the influence of his step-mother, was imprisoned, then shorn and shut up in a monastery, and afterwards became a fugitive, and was urged to head a rebellion against his father. Such was the terror, however, which the unhappy youth entertained for his cruel step-mother, that he put an end to his existence by suicide, inducing a faithful servant to strike him dead. Fredegonde's success in getting rid of one of the heirs to the throne, only partly satisfied her ambitious views. There was another son, Clovis, brother of Merovee. To rid herself of him the wily queen took another course. Three of her own children had recently died, and she ascribed their death to Clovis, whom she accused of sorcery. He was seized under this charge, thrown into prison, and there ended his career, a poniard-thrust closing his brief tale of life. The tale of murders in this direction was completed by that of the repudiated Queen Andovere, who was soon found strangled in the convent to which she had been consigned. Fredegonde had thus rid herself of all claimants to the throne outside of herself and her descendants, Galsuinthe having left no children. Though death had recently robbed her of three children, one survived, a son named Clotaire, then a few months old. Her next act of treachery was to make away with her weak and confiding husband, perhaps that she might reign alone, perhaps through fear that Chilperic might discover her guilty relations with Landry, an officer of the court, and subsequently mayor of the palace. Whatever the reason, soon after these events, King Chilperic, while in the act of dismounting on his return from the chase, was struck two mortal blows by a man who took to rapid flight, while all around the cry was raised, "Treason! it is the hand of the Austrasian Childebert against our lord the king!"
