But I didn’t do it. The unknown beyond the river once more drove me back. Besides, the adventure I had planned was not without its fascination. I wanted to see what it held in store. If it held nothing—well, then, Greeley’s Slip would still be accessible in the morning.

So I skulked back into the depths of the Park again. Those who went as twos began to disappear, and the lonely shadows to steal along more furtively. Now and then one of them approached me or hung in the distance suggestively. It was not like any of the encounters that take place in daylight. It was more as if these dark ghosts had floated up from some evil spirit land, into which before morning they would float down again.

But twelve o’clock struck at last, and I took midnight as a call. It was a call to leave the great human division in which I had hitherto been classed, and become a criminal. Once I had done this thing, I should never be able to go back. The angel with the flaming sword would guard that way, and I could never regain even such status as that which I was abandoning.

If my head had not been swimming I might at the last minute have felt a qualm at that, but my mind had lost the faculty of deconcentration. It was fixed on the thing before me in such a way that I couldn’t get it off. For this reason I went, on leaving the Park, directly to the street and number where my thoughts were.

I was surprised by the emptiness and silence of the thoroughfares. Not till then had I remembered that at this season of the year most of the houses would be closed. Closed they were, looking dark and blank and forbidding. I happened to know that the house to which I was bound was not closed; and though the fact that there were so few to pass in the streets rendered me more conspicuous, it also made me the less subject to observation.

Indeed, there were no observers at all when I approached the black spot made by the vacant lot. There was nothing but myself and the blackness. Not a light in the house! Hardly a light in any of the houses roundabout! Not a footfall on the pavements! If ever there was a good opportunity to do what I had come for, it was mine.

But I passed. The black spot frightened me. It was like a black gulf into which I might sink down. I re-passed.

I went farther up the street and took myself to task. It was a repetition of my recoil from the children in the afternoon. I must have the nerve—or I must own to myself that I hadn’t. If I hadn’t it, then I had no alternative but Greeley’s Slip.

I turned in my steps and passed the house again. If from the blank windows any one had been looking out my actions would have been suspicious. I went far down the street, and came back again far up it. Then when I had no more power of arguing with myself I suddenly found my footsteps crushing the dusty, sun-dried shoots of nettle and blue succory. I was in the vacant lot.

All at once fear left me. As well as any old hand in the business I seemed to know what lay before me. At every second some low-down prompting, sprung from nameless depths in my nature, told me what to do.
