"Ah! but, lady," replied D'Aubin, "how could you venture on such an offer, when your own brother, the very morning before, had made the same to me, and left me a certain time to deliberate and act?"

"Nay, of that I know nothing," replied Madame de Montpensier. "Had I been aware of that, of course I should have acted differently."

"But if you and your brother will play at cross purposes," said D'Aubin, "what surety is there that the promises of either will be kept? And observe the consequences of this sort of dealing! My cousin at once determined to join the forces of the king, told me the story, and thus well-nigh changed all my views and purposes, unsettled my designs, and nearly determined me to take an oath of perpetual service to the kings."

"Nay, nay," replied the Duchess, giving him her hand, "but join us at this moment of our need, and Eugenie shall be yours."

"Ay," said D'Aubin; "but I must have some better security than mere promises."

"Surely you do not doubt me," said Madame de Montpensier, "when I most solemnly declare----"

"Declare nothing, dear lady," answered D'Aubin; "I doubt nobody, but my resolution is taken. The hand of Eugenie de Menancourt must be promised to me this night, under the hand and seal of his Highness of Mayenne, as lieutenant-general of the kingdom; or when I return to the camp to-morrow, I pledge myself, in the most solemn terms, to serve the Kings of France and Navarre, till there is no such thing as a Holy League and Union in France. And more, I assure you most solemnly, that I will instantly send an order unto Maine to cut down remorselessly every acre of my old forests, in order to raise another regiment for the service of the state. Now, mark me, lady!--mark me well! In doing this, I know what I am doing; for, if you cannot obtain this written promise for me, it will be evident your brother does not intend that the hand of Eugenie should be mine, and I have no other means to obtain it, but the capture of Paris and the destruction of the League. It will be therefore well worth my while to sacrifice everything to swell the ranks of the royal forces, in order to insure success."

"Well, well, say no more, say no more," replied Madame de Montpensier; "the promise you shall have, if I have any influence with Mayenne; and besides, you say he voluntarily made it himself, and therefore he will not hesitate to write it. But tell me what are the terms in which this promise is to be couched--you mean him to promise you her hand, if she herself consents?"

"No, no," replied D'Aubin; "I will leave no hold for after tampering and intrigue by any party. But," seeing a cloud come over the brow of Madame de Montpensier at his intemperate words, "I mean not any offence to you, dear lady. Others may tamper--there are others may intrigue, and may delay her consent and our union so long that my views in favour of the League itself may be overthrown. The moment that the hand of Eugenie is mine, I will raise for the service of the Duke all the retainers of the house of Menancourt who are now either lying idle, or swelling the ranks of the royalists. What I demand then is, that your brother--acting as lieutenant-general of the kingdom, as well as calling himself so, and consequently considering himself as the lawful guardian of all wards of the crown--shall promise me, without other condition than that in three days I subscribe the Union and join my forces to his, the hand of Eugenie de Menancourt, which was promised to me by her own father."

Madame de Montpensier mused for a moment; and then rising, she replied, "It shall be done, D'Aubin; it shall be done. The world--which Mayenne fears more than he will acknowledge--can say nothing against this act, for it is but a ratification of her father's promise by him who now stands in her father's place. Here," she cried aloud, ringing a small silver bell that stood on the table before her, and which was instantly answered by the appearance of Armandi, "bring me ink and paper, René. You shall write down the promise as you would have it, D'Aubin, and I will get my brother to sign it before you go; but make haste, for every moment I expect Wolfstrom to make our third at supper."
