"Yes, by some minutes."

"There is nothing, then, to be gained by that."

"There does not seem to be."

Was his accent in uttering this simple phrase peculiar? I looked up to make sure. But his face, which had been eloquent with one feeling or another during every minute of this long interview till the present instant, looked strangely impassive, and I did not know how to press the question hovering on my lips.

"You have given me a heavy task," I finally remarked, "and you offer very little assistance in the way of conjecture. Yet you must have formed some."

He toyed with his beard, combing it with his nervous, muscular fingers, and as I watched how he lingered over the tips, caressing them before he dropped them, I felt that he was toying with my perplexities in much the same fashion and with an equal satisfaction. Angry and out of all patience with him, I blurted out:

"I will do without your aid. I will solve this mystery and earn your money if not that of Mr. Ocumpaugh, with no assistance save that afforded by my own wits."

"I expect you will," he retorted; and for the first time since I burst in upon him like one dropping from the clouds through the unapproachable doorway on the upper floor, he lost that look of extreme tension which had nerved his aged figure into something of the aspect of youth. With it vanished his impressiveness. It was simply a tired old man I now followed upstairs to the side door. As I paused to give him a final nod and an assurance of intended good faith toward him, he made a kindly enough gesture in the direction of my old room below and said:

"Don't worry about the little fellow down there. He'll come out all right. I shan't visit on him the extravagance of my own folly. I am a Christian now." And with this encouraging remark he closed the door and I found myself alone in the dark alley.

My first sense of relief came from the coolness of the night air on my flushed forehead and cheeks. After the stifling atmosphere of this underground room, reeking with the fumes of the lamp and the heat of a struggle which his dogged confidence in himself had made so unequal, it was pleasurable just to sense the quiet and the cool of the night and feel myself released from the bondage of a presence from which I had frequently recoiled but had never thoroughly felt the force of till to-night; my next, from the touch and voice of my partner who at that moment rose from before the basement windows where he had evidently been lying for a long time outstretched.
