little box which holds it is such an exquisite example of jewelers' work. There's death in its taste, almost in its smell; and it's out of my hands and—"

"Well, I'll tell you how to fix that up," I put in, with my usual frank decision. "Order the music stopped; call everybody into the drawing-room and explain the dangerous nature of this toy. After which, if anything happens, it will not be your fault, but that of the person who has so thoughtlessly appropriated it."

His eyes, which had been resting eagerly on mine, shifted aside in visible embarrassment.

"Impossible! It would only aggravate matters, or rather, would not relieve my fears at all. The person who took it knew its nature very well, and that person—"

"Oh, then you know who took it!" I broke in, in increasing astonishment. "I thought from your manner that—"

"No," he moodily corrected, "I do not know who took it. If I did, I should not be here. That is, I do not know the exact person. Only—" Here he again eyed me with his former singular intentness, and observing that I was nettled, made a fresh beginning. "When I came here, I brought with me a case of rarities chosen from my various collections. In looking over them preparatory to making a present to Gilbertine, I came across the little box I have just mentioned. It is made of a single amethyst and contains—or so I was assured when I bought it—a tiny flask of old but very deadly poison. How it came to be included with the other precious and beautiful articles I had picked out for her cadeau, I can not say; but there it was; and conceiving that the sight of it would please the ladies, I carried it down into the library and, in an evil hour, called three or four of those about me to inspect it. This was while you boys were in the billiard-room, so the ladies could give their entire attention to the little box which is certainly worth the most careful scrutiny.

"I was holding it out on the palm of my hand, where it burned with a purple light which made more than one feminine eye glitter, when somebody inquired to what use so small and yet so rich a receptacle could be put. The question was such a natural one I never thought of evading it, besides, I enjoy the fearsome delight which women take in the marvelous. Expecting no greater result than lifted eyebrows or flushed cheeks, I answered by pressing a little spring in the filigree-work surrounding the gem. Instantly, the tiniest of lids flew back, revealing a crystal flask of such minute proportions that the usual astonishment followed its disclosure.

"'You see!' I cried, 'it was made to hold that!' And moving my hand to and fro under the gas-jet, I caused to shine in their eyes the single drop of yellow liquid it still held. 'Poison!' I impressively announced. 'This trinket may have adorned the bosom of a Borgia or flashed from the arm of some great Venetian lady as she flourished her fan between her embittered heart and the object of her wrath or jealousy.'

"The first sentence had come naturally, but the last was spoken at random and almost unconsciously. For at the utterance of the word 'poison,' a quickly suppressed cry had escaped the lips of some one behind me, which, while faint enough to elude the attention of any ear less sensitive than my own, contained such an astonishing, if involuntary, note of self-betrayal that my mind grew numb with horror, and I stood staring at the fearful toy which had called up such a revelation of—what? That is what I am here to ask, first of myself, then of you. For the two women pressing behind me were—"

"Who?" I sharply demanded, partaking in some indefinable way of his excitement and alarm.

"Gilbertine Murray and Dorothy Camerden:"—his prospective bride and the woman I loved and whom he knew I loved, though I had kept my secret quite successfully from every one else!

The look we exchanged neither of us will ever forget.

"Describe the sound!" I presently said.

"I can not," he replied. "I can only give you my impression of it. You, like myself, fought in more than one skirmish in the Cuban War. Did you ever hear the cry made by a wounded man when the cup of cool water for which he has long agonized is brought suddenly before his eyes? Such a sound, with all that goes to make it eloquent, did I hear from one of the two girls who leaned over my shoulder. Can you understand this amazing, this unheard-of circumstance? Can you name the woman, can you name the grief capable of making either of these seemingly happy and innocent girls hail the sight of such a doubtful panacea with an unconscious ebullition of joy? You would clear my wedding-eve of a great dread if you could, for if this expression of concealed misery came from Gilbertine—"

"Do you mean," I cried in vehement protest, "that you really are in doubt as to which of these two women uttered the cry which so startled you? That you positively can not tell whether it was Gilbertine or—or—"

"I can not; as God lives, I can not. I was too dazed, too confounded by the unexpected circumstance, to turn at once, and when I did, it was to see both pairs of eyes shining, and both faces dimpling with real or affected gaiety. Indeed, if the matter had stopped there, I should have thought myself the victim of some monstrous delusion; but when a half-hour later I found this box missing from the cabinet where I had hastily thrust it at the peremptory summons of our hostess, I knew that I had not misunderstood the nature of the cry I had heard; that it was indeed one of secret longing, and that the hand had simply taken what the heart desired. If a death occurs in this house to-night—"

"Sinclair, you are mad!" I exclaimed with great violence. No lesser word would fit either the intensity of my feeling or the confused state of my mind. "Death here! where all are so happy! Remember your bride's ingenuous face! Remember the candid expression of Dorothy's eye—her smile—her noble ways! You exaggerate the situation. You neither understand aright the simple expression of surprise you heard, nor the feminine frolic which led these girls to carry off this romantic specimen of Italian deviltry."

"You are losing time," was his simple comment. "Every minute we allow to pass in inaction only brings the danger nearer."

"What! You imagine—"

"I imagine nothing. I simply know that one of these girls has in her possession the means of terminating life in an instant; that the girl so having it is not happy, and that if anything happens to-night it will be because we rested supine in the face of a very real and possible danger. Now, as Gilbertine has never given me reason to doubt either her affection for myself or her satisfaction in our approaching union, I have allowed myself—"

"To think that the object of your fears is Dorothy," I finished with a laugh I vainly strove to make sarcastic.

He did not answer, and I stood battling with a dread I could neither conceal nor avow. For preposterous as his idea was, reason told me that he had some grounds for his doubt.

Dorothy, unlike Gilbertine Murray, was not to be read at a glance, and her trouble—for she certainly had a trouble—was not one she chose to share with any one, even with me. I had flattered myself in days gone by that I understood it well enough, and that any lack of sincerity I might observe in her could be easily explained by the position of dependence she held toward an irascible aunt. But now that I forced myself to consider the matter carefully I could not but ask if the varying moods by which I had found myself secretly harrowed had not sprung from a very different cause—a cause for which my persistent love was more to blame than the temper of her relative. The aversion she had once shown to my attentions had yielded long ago to a shy, but seemingly sincere appreciation of them, and gleams of what I was fain to call real feeling had shown themselves now and then in her softened manner, culminating to-day in that soft pressure of my hand which had
