He was not yet accustomed to life in a great city, and it did not seem wise, either, to permit him to walk home alone, or to wait for me in the hotel among strangers. He did not seem quite content to stay, however, and there was a troubled expression on his face, which was new to it, and which I could not put out of my mind after I had left the house. The hotel to which I had been directed was on Union Square. It was not far from our apartments, and I intended to walk there, but I had not gone half a block before the street was lit up with a vivid flash of lightning, followed by deafening thunder, and the wind blew damp in my face. I hurried toward Third Avenue, intending to mount one of the horse cars going down-town, but suddenly a fierce gust of wind swept over me, sowing great drops of rain along the pavement. I looked about for a cab. The street was deserted and so dark that I could see nothing except the gloomy rows of brown stone that stood on either side. While I was looking backward another flash of lightning illumined the street. What man was that coming in the distance? Was it Rayel? No, that was scarcely possible. I had only caught a momentary glimpse of him in the quick flash. He was tall and erect like Rayel, and I thought the hat was his. But my imagination must have tricked me after all, for nothing showed clearly. I walked back a few steps and listened. I could hear no footsteps, but then he might have followed me, and I ought to be sure. So I called, “Rayel! Rayel!” twice, and waited for an answer, but could hear none. I had not time to go back to our rooms, as Hester was undoubtedly waiting for me now, and Rayel was certainly not the man I had seen, or he would have answered me. So I hurried along without giving any further thought to my fears. But where was Third Avenue? Its character was not then so sharply defined as in these days of elevated rail-roads--perhaps I had passed it. I had already walked a long distance, and I had not yet recognized that thoroughfare. I could hear footsteps behind me and I determined to wait a moment and inquire my way.
