At sight of the long row of uniform buildings, with their pillared fronts and connecting balconies every detail of the crime which had filled the papers at the time with innumerable conjectures returned to me with extraordinary clearness, and, before I knew it, I found myself standing stockstill in the middle of the block with my eye raised to the Hasbrouck house and my ears--or rather my inner consciousness, for no one spoke I am sure--ringing with a question which, whether the echo of some old thought or the expression of a new one, so affected me by the promise it held of some hitherto unsuspected clue, that I hesitated whether to push this new inquiry then or there by an attempted interview with Mrs. Hasbrouck, or to wait till I had given it the thought which such a stirring of dead bones rightfully demanded. You know what that question was. I shall have communicated it to you, if you have not already guessed it, before perusing these lines: “Who uttered the scream which gave the first alarm of Mr. Hasbrouck’s violent death?” I was in a state of such excitement as I walked away--for I listened to my better judgment as to the inadvisability of my disturbing Mrs. Hasbrouck with these new inquiries--that the perspiration stood out on my forehead.

Choosing such persons as I thought most open to my questions, I learned that there were many who could testify to having heard a woman’s shrill scream on that memorable night, just prior to the alarm given by old Cyrus, but no one who could tell from whose lips it had come. One fact, however, was immediately settled. It had not been the result of the servant-women’s fears. Both of the girls were positive that they had uttered no sound, nor had they themselves heard any till Cyrus rushed to the window with his wild cries. As the scream, by whomever given, was uttered before they descended the stairs, I was convinced by these assurances that it had issued from one of the front windows, and not from the rear of the house, where their own rooms lay. Could it be that it had sprung from the adjoining dwelling, and that--
