"Madame la Princesse," he said, after a pause, "the subject, as you observed just now, is a delicate one. I regret that I should be obliged to give you pain. Even had I not received your telegram, I should have felt it to be my duty to come to see you on this matter."

"You knew it, then?" asked the princess, more bewildered than ever.

"Yes, I knew it," replied the priest. "It came to my knowledge only three or four days since. I fear, madame, that Donna Bianca has given this young man every reason to feel himself justified in persuading his father to address this letter to you. That does not excuse his presumption—certainly not! But, as I say, it makes it more reasonable."

Princess Montefiano turned to him with some dignity. "Monsieur l'Abbé," she said, "are you aware what your words imply? You are speaking of my step-daughter, of Donna Bianca Acorari."

The Abbé Roux spread out his hands apologetically. "Alas, madame!" he replied, "I am fully aware of it. But I consider it to be my duty to speak to you of Donna Bianca. I think," he added, "that you have never had cause to complain of my failing in my duty towards Casa Acorari, or of any lack of discretion on my part, since you honored me with your confidence."

"That is true," said Princess Montefiano, hurriedly; "I ask your pardon, Monsieur l'Abbé. I am sure that whatever you may have to tell me is prompted by your sense of the confidence I repose in you. But, Bianca! I do not understand—"

"It is a very simple matter," interrupted the abbé. "A person of my acquaintance was an accidental witness of an interview between Donna Bianca and young Rossano—here in the grounds of the Villa Acorari—a few days ago. It appears that there can be no doubt it was a lover's interview, and probably not the first of its kind between these two young people."

The princess turned a horrified gaze upon him.

"And you call that a simple matter!" she exclaimed, so soon as she could find words.

The abbé shrugged his shoulders.
