"Which one? There are three letters, but each of them is written in a different hand. You said so yourself."

"I may have been mistaken. I think I will examine them more closely. Let us take a seat in front of that café. I see a table in a corner where we shall be comparatively alone."

George Caumont assented to the proposal, and as soon as the friends were seated in a little niche in front of the Café Américain, Puymirol opened the pocket-book. "Let us proceed systematically," he remarked. "Here is the first letter. It is not long, but it is expressive. 'My adored one,' it says, 'I am ready to leave everything to follow you, and to sacrifice, for your sake, all that I prize most in this world, my children and my good name. When shall we start? Say the word, and I will join you. Take me to the end of the world, and make me your slave. I shall be only too happy, for I cannot live apart from you.' I have skipped the kisses. There are too many of them," concluded Adhémar, sneering.

"My children!" repeated George, ironically. "Then Blanche certainly did not write that letter. She has no children."

"Nor has Madame de Lescombat any. But let us examine the next missive: 'My friend, I have loved you, I love you still; but if you go on in this way, I shall no longer love you. I shall even hate you, and I do not conceal from you that there lurks in my heart a feeling that you would do well not to arouse. Have you ever seen Sardou's "Hatred" played? Well, I am a Florentine Parisienne, and I should know how to avenge my wrongs, as Italian women revenged theirs in the middle ages. These are no meaningless threats, my dear. To extricate you from a terrible predicament I once committed an act that might have sent me straight to the Assizes, and I mean to be rewarded by your devotion. You must choose between her and me. You understand me, do you not? I await in reply, not words, but acts. I shall expect you to-morrow, you bad fellow, whom I love so much. Bring me what you swore to return to me, or there will be bitter war.'"

"The deuce!" exclaimed George, "that woman doesn't bandy words. I should think her quite capable of conniving at Dargental's murder to regain possession of a letter in which she owns that she had committed a crime. She does not state what crime, but she may have committed forgery; and if Dargental profited by the deed, as she says clearly enough, he certainly had good reason to fear her vengeance."

"Then, if this letter came from Blanche Pornic, you would be inclined to think that the murder was committed by her orders, and for her benefit?"

"I would not swear that such was the case; but it would seem very probable."

"Well, I know her; and I am sure that she was the writer of this threatening missive. 'You must choose between her and me.' 'Her' is Madame de Lescombat, her rival; and I would wager almost any amount that the letter is not a week old. A day or two after it was written, Dargental's intended marriage was announced. He had refused to fulfil his promise, and Blanche avenged herself accordingly."

"But if they had quarrelled to that point, he would not have invited her to lunch with us this morning."
