"Attempted to kill the king!" said Madame de Montpensier, but ill concealing, in her desire to hear more, her previous knowledge of the act that had been perpetrated--"attempted! Then he did not kill him."

"Oh, no," replied D'Aubin, gaily, and purposely affecting to laugh at her disappointment. "You do not think Henry is such a fool as to let himself be killed by a bungling Dominican. You should have sent our friend in the next room there, Armandi, or some other skilful, delicate, dexterous personage. Besides, dear lady, when you and Armandi and good father Bourgoin were consulting together, surely three such shrewd heads as yours might have fallen upon some better and more politic plan of getting rid of a bad king than that of trusting the execution of the act to an ignorant, clumsy, timid friar. Good faith! I should have thought that you might have even acted Judith yourself, and have delivered the land of our worthy Holofernes of St. Cloud with your own hand."

Madame de Montpensier turned pale, and red, and pale again; and there was a quivering of her fine lip, and a flashing of her proud dark eye, which showed D'Aubin at length that he was urging her too far. As soon as he perceived it, he dropped the sarcastic irony which he had been using; and drawing nearer to her, he took her fair, soft, jewelled hand in his, and raised it to his lips. "Forgive me," he said, "for teasing you. I love not Henry of Valois more than you do--as you well know; and though I will not say that I regret your attempt has failed, yet I do believe that all knowledge of the share you had in it rests with me alone, and, believe me, my lips are and shall ever be sealed by this kiss upon this hand--except towards yourself."

Madame de Montpensier gazed on him in no small surprise. "You assume things, sir," she said with some hesitation, "which you have no right to assume."

"Nay, nay," replied D'Aubin, "say not a word, dear lady. I know the whole as well as if I had been one of your triumvirate at the Jacobins the day before yesterday, all the means employed, the vision of the angel, and all----"

"Either some one has betrayed me, or you deal in magic, D'Aubin!" cried the Duchess.

D'Aubin smiled to see her consternation; for although, by combining the information he had received from St. Real with the hints that had been given him by the dwarf, and adding thereunto his own knowledge of the parties, he had been able to form a very correct guess at the truth--and although he knew the effect which vague hints of greater knowledge than one possesses, supported by one or two distinct facts, will produce upon a mind loaded with a heavy secret and apprehensive of discovery, yet he had hardly calculated upon so completely deceiving such a shrewd intriguer as Madame de Montpensier, in regard to the extent of his information. "No one has betrayed you," he replied; "nor do I deal in magic; but I have far greater means of knowing things that pass both in the city and in the camp than you suppose. What I have said just now I said but to tease you; and, indeed, fair lady, you deserve somewhat worse at my hands."

"Wherefore, wherefore? How so?" demanded Madame de Montpensier; "how have I offended you, D'Aubin?"

"Why, I do think," replied D'Aubin, "that considering all the old friendships which had existed between us, it should not have been you who attempted to mar my fortunes, and thwart my purposes. Did you not only last night propose to my cousin St. Real to bestow on him the hand of my promised bride?"

"I did," replied Madame de Montpensier, boldly, recovering in a moment all her composure--"I did, and I will tell you why I did so, Philip d'Aubin. I saw, by your conversation of the day before, that you had irretrievably attached yourself to the party of the tyrant; and I consider the interests of our cause far before any private interests or friendships. I am resolved, and so I know also is Mayenne, that the hand of Mademoiselle de Menancourt shall never be given to any but a member of the union; and it was therefore that I offered her hand to your cousin, if he would bring his forces to our side."
