Catherine De' Medici by Honoré De Balzac

This noble chateau of Blois was to Catherine de' Medici the narrowest of prisons. On the death of her husband, who had always held her in subjection, she expected to reign; but, on the contrary, she found herself crushed under the thraldom of strangers, whose polished manners were really far more brutal than those of jailers. No action of hers could be done secretly. The women who attended her either had lovers among the Guises or were watched by Argus eyes. These were times when passions notably exhibited the strange effects produced in all ages by the strong antagonism of two powerful conflicting interests in the State. Gallantry, which served Catherine so well, was also an auxiliary of the Guises. The Prince de Conde, the first leader of the Reformation, was a lover of the Marechale de Saint-Andre, whose husband was the tool of the Grand Master.

The cardinal, convinced by the affair of the Vidame de Chartres, that Catherine was more unconquered than invulnerable as to love, was paying court to her. The play of all these passions strangely complicated those of politics, -- making, as it were, a double game of chess, in which both parties had to watch the head and heart of their opponent, in order to know, when a crisis came, whether the one would betray the other.
