“You will discover there,” she whispered, “a hand of bronze lying on an enamelled cushion. On the fingers of this hand there should be, and doubtless are, rings of forged steel of peculiar workmanship. If there is one on the middle finger, my cause is lost, and I can only await the end.” Her cheek paled. “But if there is not, you may be sure that an attempt will be made by some one to-morrow—I do not know whom—to put one there before the office closes at noon. The ring will be mine—the one stolen from my hand just now—and it will be your business to prevent the box being opened for this purpose, by any means short of public interference involving arrest and investigation; for this, too, would be fatal. The delay of a day may be of incalculable service to me. It would give me time to think, if not to act. Does the undertaking seem a hopeless one? Am I asking too much of your inexperience?”

“It does not seem a hopeful one,” I admitted; “but I am willing to undertake the adventure. What are its dangers? And why, if I see the ring on the finger you speak of, cannot I take it off and bring it back to you?”

“Because,” said she, answering the last question first, “the ring becomes a part of the mechanism the moment it is thrust over the last joint. You could not draw it off. As for the dangers I allude to, they are of a hidden character, and part of the secret I mentioned. If, however, you exercise your wit, your courage, and a proper amount of strategy, you may escape. Interference must be proved against you. That rule, at least, has been held inviolate.”

Aghast at the mysterious perils she thus indicated in the path toward which she was urging me, I for one instant felt an impulse to retreat. But adventure of any kind has its allurements for an unoccupied youth of twenty-one, and when seasoned, as this was, by a romantic, if unreasonable, passion, proved altogether too irresistible for me to give it up. Laughing outright in my endeavor to throw off the surplus of my excitement, I drew myself up and uttered some fiery phrase of courage, which I doubt if she even heard. Then I said some word about the doctor, which she at once caught up.

“The doctor,” said she, “may know, and may not know, the mysteries of that box. I would advise you to treat him solely as a doctor. He who uses the key you now hold in your hand cannot be too wary; by which I mean too careful or too silent. Oh, that I dared to go there myself! But my agitation would betray me. Besides, my person is known, or this ring would never have been taken from me.

“I will be your deputy,” I assured her. “Have you any further instructions?”

“No,” said she; “instructions are useless in an affair of this kind. Your actions must be determined by the exigencies of the moment. Meantime, my every thought will be yours. Good-night, sir; pray God, it may not be good-by.”

“One moment,” I said, as I arose to go. “Have you any objection to telling me your name?”

“I am Miss Calhoun,” she said, with a graceful bow.

This was the beginning of my formidable adventure with the bronze hand.
