"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 awakened my hopes and made me forget all the doubts and caprices of a disturbing courtship.

But, had I interpreted that strong, nervous pressure aright? Had it necessarily meant love? Might it not have sprung from a sudden desperate resolution to accept a devotion which offered her a way out of difficulties especially galling to one of her gentle but lofty spirit? Her expression when she caught my look of joy had little of the demure tenderness of a maiden blushing at her first involuntary avowal. There was shrinking in it, but it was the shrinking of a frightened woman, not of an abashed girl; and when I strove to follow her, the gesture with which she waved me back had that in it which would have alarmed a more exacting lover. Had I mistaken my darling's feelings? Was her heart still cold, her affection unwon? Or—thought insupportable!—had she secretly yielded to another what she had so long denied me and—
