"I was to wait two weeks. Why she exacted so long and seemingly unnecessary a delay, I do not know. Before I saw her, I thought it was from a sheer desire to make me suffer; now I know it was not for that. However, it did make me suffer, from the alternate weakening and strengthening of my resolve. When the day came, the most trivial of circumstances would have deterred me from what still had the nature of a dream to me. Unhappily, everything worked for its fulfillment. There had never been fewer persons in the building at the noon hour; nor had there been a time during the past two weeks when the Curator was more completely occupied in a spot quite remote from his office. As I tried the door leading up the little winding staircase to the one back of the tapestry where the bow lay, and found it, just as I had left it, unlocked, I had a sense for the first time that the courage concerning which I had had so many doubts would hold. At that moment I was a murderer in heart and purpose, whatever I was after or have been since. As I recognized this fact, I felt my face go pale and my limbs shake from sheer horror of myself. But this weakness was short-lived and I felt my blood flowing evenly again when having slipped into my place behind the upper pedestal I peered through my peep-hole in a search for her figure in the spot where I had bidden her await me.
"She was not there, but then it was not quite twelve, though the noon hour was so near she must be somewhere in the gallery and liable at any minute to cross my line of vision.
"It was fifteen years, as I have already said, since I had seen her; and I had no other picture of her in my mind than the appearance she had made as a girl, coarsened by time and disappointment. Why I should have looked for just this sort of change in her, God knows, but I did expect it and probably would not have recognized her if I had passed her in the court. But I was not worrying about any mistake I might make of this kind. All I seemed to fear was that at the critical moment some one would pass between us on my side of the gallery. I never thought of anyone passing in front of her.
"I had picked out Section II as the place where she was to show herself, because it was in a direct line with the course an arrow would take from a sight behind the vase. I had bade her to look for me in the court, and that would bring her forward to the balustrade in front. A knot of scarlet ribbon at her breast was to distinguish her. But the spot I had thus chosen for her, and the spot I had chosen for myself had this disadvantage; that while I could see straight to my mark from the peep-hole I have mentioned, I could see nothing to right or left of that one line of vision. Why I did not realize the hazard involved in this fact I do not know. Enough that my whole thought was centered on the lookout I was keeping and it was with a shock of surprise I suddenly saw the whole scene blotted from my view by the passing by of some one on my own side of
