feet descend the stair. But when I sought to follow, I found myself for the second time overwhelmed by darkness. The gas jet, which had hitherto burned with great brightness in the small room, had been turned off from below, and beyond the faint glimmer which found its way through the small window of which I have spoken, not a ray of light now disturbed the heavy gloom of this gruesome apartment.

"I had thought of every contingency but this, and for a few minutes my spirits were dashed. But I soon recovered some remnants of self-possession, and began feeling for the knob I could no longer see. Finding it after a few futile attempts, I was relieved to discover that this door at least was not locked; and, opening it with a careful hand, I listened intently, but could hear nothing save the smothered sound of men talking in the room below.

"Should I signal for my companions? No, for the secret was not yet mine as to how men passed from this room into the watery grave which was the evident goal for all wearers of the blue ribbon.

"Stepping back into the middle of the room, I carefully pondered my situation, but could get no further than the fact that I was somehow, and in some way, in mortal peril. Would it come in the form of a bullet, or a deadly thrust from an unseen knife? I did not think so. For, to say nothing of the darkness, there was one reassuring fact which recurred constantly to my mind in connection with the murders I was endeavoring to trace to this den of iniquity.

"None of the gentlemen who had been found drowned had shown any marks of violence on their bodies, so it was not attack I was to fear, but some mysterious, underhanded treachery which would rob me of consciousness and make the precipitation of my body into the water both safe and easy. Perhaps it was in the bottle of brandy that the peril lay; perhaps—but why speculate further! I would watch till midnight and then, if nothing happened, signal my companions to raid the house.

"Meantime a peep into the next room might help me towards solving the mystery. Setting the bottle and glass aside, I dragged the table across the floor, placed it under the lighted window, mounted, and was about to peer through, when the light in that apartment was put out also. Angry and overwhelmed, I leapt down, and, stretching out my hands till they touched the wainscoting, I followed the wall around till I came to the knob of the door, which I frantically clutched. But I did not turn it immediately, I was too anxious to catch these villains at work. Would I be conscious of the harm they meditated against me, or would I imperceptibly yield to some influence of which I was not yet conscious, and drop to the floor before I could draw my revolver or put to my mouth the whistle upon which I de-pended for assistance and safety? It was hard to tell, but I determined to cling to my first intention a little longer, and so stood waiting and counting the minutes, while wondering if the captain of the police boat was not getting impatient, and whether I had not more to fear from the anxiety of my friends than the cupidity of my foes.

"You see I had anticipated communicating with the men in this boat by certain signals and tokens which had been arranged between us. But the lack of windows in the room had made all such arrangements futile, so I knew as little of their actions as they of my sufferings; all of which did not tend to add to the cheerfulness of my position.

"I, however, held out for a half-hour, listening, waiting and watching in a darkness which, like that of Egypt, could be felt, and when the suspense grew intolerable I struck a match and let its blue flame flicker for a moment over the face of my watch. But the matches soon gave out and with them my patience, if not my courage, and I determined to end the suspense by knocking at the door beneath.

"This resolution taken, I pulled open the door before me and stepped out. Though I could see nothing, I remembered the narrow landing at the top of the stairs, and,
