"No, you have some other ruse, mademoiselle," said I. "Perhaps you wish to gain time for your friend in the next room. No, we will return here and open it comfortably by the fire."

I kept a tight hold upon the box. I shook it. To my delight I felt that there were papers within it. I carried it back to the fireside and sat down on a chair. Mademoiselle Sophie followed me close, and as I fixed the little gold key into the lock she laid her hand very gently upon my arm.

"I beg you not to unlock that box," she said; "if you do you will bring upon me a great humiliation and upon yourself much remorse. There is nothing there which concerns you. There are just my little secrets. A girl may have secrets, monsieur, which are sacred to her."

She was standing quite close to me, and her back was towards the French officer and her aunt. They could not see her face and they could hardly have heard more than a word here and there of what she said. For always she spoke in a low voice, and at times that low voice dropped to a whisper, so that I myself had to watch her lips. I answered her only by turning the key in the lock. She took her hand from my arm and laid it on the lid to hinder me from opening it.

"I wore the key on a chain about my neck, monsieur," she whispered. "Does that teach you nothing? Even though you are young, does it teach you nothing? I said that if you unlocked that box you would cause me great humiliation, thinking that would be enough to stop you. But I see I must tell you more. Read the letters, monsieur, question me about them, and you will make my life a very lonely one. I think so. I think you will destroy my chance of happiness. You would not wish that, monsieur? It is true that we are enemies, but some day this war will end, and you would not wish to prolong its sufferings beyond the end. Yet you will be doing that, monsieur, if you open that box. You would be sorry afterwards when you were back at home to know that a girl in France was suffering from a needless act of yours. Yes, you will be sorry if you open that box."

It seems now almost impossible to me that I could have doubted her sincerity; she spoke with so much simplicity, and so desperate an appeal looked out from her dark eyes. Ever since that Christmas night I can see her quite clearly at will, standing as she stood then--all the sincerity of her which I would not acknowledge, all the appeal which I would not hear; and I see her many times when for my peace I would rather not. Much remorse, she said very wisely, would be the consequence for me. She was pleading for her pride, and to do that the better she laid her pride aside; yet she never lost her dignity. She was pleading for her chance of happiness, foreseeing that it was likely to be destroyed, without any reason or any profit to a living being, by a stranger who would the next moment pass out of her life. Yet there was no outcry, and there were no tears. Had it been a trick--I ask the ladies--would there not have been tears?

But I thought it was a trick and a cheap one. She was trying to make me believe that there were love-letters in the box--compromising love-letters. Now, I know that there were no love-letters in the box. I had seen the Frenchman's pretty way of saying thanks. I had noticed how the caress hurt her just through what it lacked. He was the friend, you see, and nothing more; she was the lover and the only lover of the pair. There could be no love-letters in the box unless she had written them herself and kept them. But I did not think she was the girl to do that. There was a dignity about her which would have stopped her pen.

I opened the box accordingly. Mademoiselle Sophie turned away abruptly, and sitting down in a chair shaded her eyes with her hand. I emptied the letters out on to a table, turning the box upside down, and thus the first which I took up and read was the one which lay at the very bottom. As I read it it seemed that every suspicion I had formed was established. She had hinted at love-letters, she had spoken of secrets sacred to a girl; and the letter was not even addressed to her. It was addressed to Madame de Villetaneuse; it was a letter which, if it meant no more than what was implied upon the surface, would have long since found destruction in the waste-paper basket. For it purported to be merely the acceptance of an invitation to dinner at the town house of Madame de Villetaneuse in the Faubourg St. Germain. It was signed only by a Christian name, "Armand," and the few sentences which composed the letter explained that M. Armand was a distant kinsman of Madame de Villetaneuse who had just come to Paris to pursue his studies, and who, up till now, had no acquaintance with the family.

I looked at Mademoiselle Sophie sternly. "So all this pother was about a mere invitation to dinner! Once let it be known that M. Armand will dine with Madame de Villetaneuse in the Faubourg St. Germain, and you are humiliated, you lose your chance of happiness, and I, too, shall find myself in good time suffering the pangs of remorse," and I read the letter slowly aloud to her, word by word.

She returned no answer. She sat with her hand shading her face, and she rocked her head backwards and forwards continually and rather quickly, like a child with a racking headache. Of course, to my mind all that was part of the game. The letter was dated two years back, but the month was December, and, of course, to antedate would be the first precaution.
