"I do not explain it, monsieur. I merely confine myself to a plain statement of the facts of the case. I am as much interested in clearing up this mystery as you can possibly be."

"Oh, I will have my revenge!" exclaimed M. d'Infreville, his long repressed rage bursting forth at last. "I can doubt no longer now. The discovery that my wife has been absenting herself from home for days at a time naturally aroused my suspicions. I inquired the cause of these frequent and prolonged absences; she replied that she often went to spend the day with a former schoolmate, named Madame de Luceval. The name was so widely known and respected, the excuse so plausible, my wife's manner so sincere, that I, like a fool, believed her. Now, I know that it was an instinctive distrust that impelled me to seek you out. You see what I have discovered. Oh, the infamous wretch!"

"Be calm, I beg of you," entreated M. de Luceval, "your excited manner is attracting attention. Let us take a cab, and drive to my house at once, monsieur, for this mystery must be cleared up. I shudder to think that my wife, impelled by a desire to protect her friend, has consented to become an accomplice in a shameful deception. Come, monsieur, come. I count upon you, and you, in turn, can count upon me. It is the duty of all honest men to aid and sustain each other under such distressing circumstances. Justice must be done, and the guilty must be punished."

"Yes, yes. I will have my revenge! You may be sure I will have my revenge!"

He was trembling with rage, and his excitement increased his weakness to such an extent that he was obliged to lean heavily upon his companion's supporting arm to reach the carriage.

It was about an hour after this chance meeting of the two gentlemen that Florence received the note from her husband announcing that he would not dine at home that day.

So while this matrimonial storm is becoming more and more threatening, we will return to the two ladies who were left alone together after the departure of the maid who had brought M. de Luceval's note.

CHAPTER IV.
THE CONFESSION.

THE maid had no sooner quitted the apartment than Madame d'Infreville said to her friend:

"You proposed I should spend the rest of the day here, my dear Florence, and I accept your offer, so as to give a semblance of truth to my falsehood in case there should be any trouble."
