"I shall hold my peace, Madame, and you will have refused to save my life."

"Do you know, Monsieur," replied Diane, "that you have strangely aroused my woman's curiosity'? Yes, the mystery with which you so tragically surround yourself attracts me and tempts me, I confess. You have triumphed over my imagination to that extent, I tell you frankly; and I did not suppose that any one could so pique my curiosity. If I swear, it is, I give you fair warning, so that I may learn more about you. From curiosity, pure and simple, I agree to do it."

"And I too, Madame," said Gabriel, "I implore you thus, so that I may learn more; but my curiosity is that of the criminal awaiting his death-sentence. Bitter and fearful curiosity, as you see! Will you take this oath, Madame?"

"Say you the words, and I will say them after you, Monsieur."

And Diane said, after Gabriel, the following words:

"By my salvation, in this life and the next, I swear to reveal to no one on earth the secret which you are about to impart to me, and never to make any use of it to injure you, and to act in all ways just as if I had never known it, and never should know it."

"Very well," said Gabriel, "and I thank you for this first proof of your condescension. Now, in two words, you shall know all: my name is Gabriel de Montgommery, and Jacques de Montgommery was my father!"

"Your father!" cried Diane, springing to her feet in a state of stupefied excitement.

"So that if Diane de Castro is the count's daughter," said Gabriel, "Diane de Castro, whom I love, or whom I thought that I loved to distraction, is my sister!"

"Ah, I see," replied Diane de Poitiers, recovering herself a bit.—"This will be the constable's salvation," she thought to herself.
