"And you yourself have no suspicion, no faint idea of the cause of such a letter as that?"

"I cannot even attempt to guess at it."

"There are none of your lady friends who would hazard a joke with you?"

"Oh, no; they could not think of such a joke as that, and my few friends love me, I believe."

I had now begun to pace up and down the room, being in a very whirl of theory and conjecture. And, in truth, the problem presented so many possibilities that it might well have troubled a man whose whole occupation was the solution of mysteries. Not that I lacked any clue, for my knowledge, such as it is, of the heartburnings, the jealousies, and the crimes which hover over the possession of precious stones at once compelled me to the conclusion, either that M. Georges Barré had been the victim of a previous affaire du cœur, or that his fiancée had been won only over trampled hopes and vain rivalries. In either case (the case of the woman who resented the man's marriage, or the man who resented the woman's) was there ample warranty for such a letter as Mademoiselle Bernier had received. Yet was I too slow to venture the question with her, and did so at last in sheer pity for her childishness.

"Tell me," said I, stopping of a sudden before her, "what led you to me?"

"Madame Carmalovitch," said she. "I went to her first, but she knew you were in Paris, and would not rest until I had consented to see you. She would have come with me, but is latterly almost always unable to face the night air."

"You have no one else you would care to consult in such a case?"

"No one," said she.

"And if you go to the ball to-night without your bracelet——?"
