Indeed, the fine Château of Blois was to Catherine the strictest prison. On the death of her husband, who had always kept her in leading-strings, she had hoped to rule; but, on the contrary, she found herself a slave to strangers, whose politeness was infinitely more cruel than the brutality of jailers. She could do nothing that was not known. Those of her ladies who were attached to her either had lovers devoted to the Guises, or Argus eyes watching over them. Indeed, at that time the conflict of passions had the capricious vagaries which they always derive from the powerful antagonism of two hostile interests in the State. Love-making, which served Catherine well, was also an instrument in the hands of the Guises. Thus the Prince de Condé, the leader of the Reformed party, was attached to the Maréchale de Saint-André, whose husband was the Grand Master's tool. The Cardinal, who had learned from the affair of the Vidame de Chartres that Catherine was unconquered rather than unconquerable, was paying court to her. Thus the play of passions brought strange complications into that of politics, making a double game of chess, as it were, in which it was necessary to read both the heart and brain of a man, and to judge, on occasion, whether one would not belie the other. Though she lived constantly under the eye of the Cardinal de Lorraine or of his brother, the Duc François de Guise, who both distrusted her, Catherine's most immediate and shrewdest enemy was her daughter-in-law, Queen Mary, a little fair girl as mischievous as a waiting-maid, as proud as a Stuart might be who wore three crowns, as learned as an ancient scholar, as tricky as a school-girl, as much in love with her husband as a courtesan of her lover, devoted to her uncles, whom she admired, and delighted to find that King Francis, by her persuasion, shared her high opinion of them. A mother-in-law is always a person disliked by her daughter-in-law, especially when she has won the crown and would like to keep it--as Catherine had imprudently too plainly shown. Her former position, when Diane de Poitiers ruled King Henri II., had been more endurable; at least she had enjoyed the homage due to a Queen, and the respect of the Court; whereas, now, the Duke and the Cardinal, having none about them but their own creatures, seemed to take pleasure in humiliating her. Catherine, a prisoner among courtiers, was the object, not every day, but every hour, of blows offensive to her dignity; for the Guises persisted in carrying on the same system as the late King had employed to thwart her.
