Unluckily, Princess Montefiano had struck a wrong chord.

"It was nothing of the sort," Bianca exclaimed, indignantly. "It is perfectly true that we met, there in the ilex grove at the Villa Acorari, and I suppose our meeting was seen, and that you were told of it."

"Of course," interrupted the princess. "My brother saw you. Did you not know it was he who heard voices in the casino, and then saw you and—and that young man emerge from it?"

Bianca started violently. "Liar!" she exclaimed, under her breath.

"It seems to me that it is a further proof of my brother's generosity," continued Princess Montefiano. "Knowing all the circumstances, he has from the first endeavored to shield you."

Bianca laughed a quiet but not very pleasant laugh.

"Sicuro!" she said. "It is a further proof of Monsieur d'Antin's generosity. It appears that everybody at Montefiano is disinterested—my uncle, Monsieur l'Abbé, everybody! But you will explain to them that I need no sacrifices. Ah, it is of no use to interrupt me now! I have learned all I wanted to know, and you—you will learn something from me—something final, definite. It is this: I will marry Silvio Rossano when I am Principessa di Montefiano and my own mistress, and until that time I will wait, unless—"

Princess Montefiano turned towards her, her face quivering with anger.

"Unless—what?" she asked.

"Unless he wishes me to marry him before," answered Bianca, quietly.
