It was a face made to express passion. And, although the only passion expressed now was that of despair, so intense that it grew like apathy, I could easily see how the rounded chin and full lips could melt into softer moods. The forehead was rather low, but fair, consorting with the oval of the cheek and chin; the brows dark and rather heavy. I remembered the wild black eyes which I had seen the previous day, and could guess at their hidden fires. This was a girl to attract interest at any time, and I mutely wondered what had entangled the threads of her fate in the glittering web of a higher fortune, which was now suddenly interwoven with the pall of death. All her movements had been such as to confirm my desire to ascertain her connection, if any, with the tragedy. It seemed to me that if I could see her eyes, before she was conscious of observance, I could tell whether there was guilt, or only sorrow, in her heart; therefore I remained quiet, waiting. But I had mistaken my powers, or the eyes overbore them. When she did lift them, as a steamer came puffing around the base of the mountain which ran down into the river at the east, and they suddenly encountered mine, where I stood not ten feet from her, I saw only black, unfathomable depths, pouring out a trouble so intense, that my own gaze dropped beneath their power. She did not start, upon observing me, which, as I thought, a guilty person, buried in self-accusing reveries, would have done--it seemed only slowly to penetrate her consciousness that a stranger was confronting her; when I raised my eyes, which had sunk beneath the intensity of hers, she was moving rapidly away toward the western gate. "Miss Sullivan, you have forgotten your bonnet." With a woman's instinct she put up her hand to smooth her disordered hair, came slowly back and took the bonnet which I extended toward her, without speaking. I hesitated what move to make next. I wished to address her--she was here, in my grasp, and I ought to satisfy myself, as far as possible, about the suspicions which I had conceived. I might do her an irreparable injury by making my feelings public, if she were innocent of any aid or instigation of the crime which had been committed, yet there were circumstances which could hardly pass unchallenged. That unaccountable absence of hers on Saturday, from three o'clock until an hour after the murder was committed; the statement of her aunt that she was in the city, and my finding her in this spot, in connection with the midnight visit to the window, and the other things which I had observed, were sufficient to justify inquiry. Yet, if I alarmed her prematurely I should have the less chance of coming upon proofs, and her accomplices, if she had any, would be led to take steps for greater safety. Anyhow, I would make her speak, and find what there was in her voice. "Your aunt told me that you had gone to New York," I said, stepping along beside her, as she turned away.
