The only people in sight were a couple of policemen, but, Mr. Dingley on one side and father on the other, fairly lifted me out by the arms, and hurried me into the building, as if they were afraid of being caught by some one. The first thing I was aware of was the cold gray light falling on us from high overhead, and a faint sickly odor, very faint but very penetrating, the like of which I had never breathed before. We were standing in a flagged hall, looking up through a great well, past gallery after gallery, to a skylight covering the top of the roof. It was the sunshine filtering through the dull, thick, greenish glass which gave that cold, sad-colored light. Within the galleries I caught glimpses of men at work at desks; and over the railings lounged figures, peered faces, disheveled, sodden, disreputable; and sometimes near these a policeman's star twinkled. I saw it all in one upward glance, for I was hurried on. Our steps clattered over the flags of the hall, and then, turning to the right, we began to go down-stairs. I took tighter hold on father's arm, for we seemed to be descending into a dungeon. That sickly, acrid odor grew heavier, making me think of caged animals, and yet, what made it worse, it wasn't quite like an animal either. The hall we came out into was smaller and darker than the one above it, and empty except for a policeman standing by a door. To him Mr. Dingley handed his card, and, after a few minutes, we were admitted to a small office. It was divided in half by a railing; on the inner side was a desk, at which a man with a star on his coat was writing under the light of a green-shaded lamp. He came forward, opened a gate in the railing for us to enter, shook hands with Mr. Dingley and father, and then was introduced to me. His name did not reach me, but I understood the words "Chief of Police." Then all three talked together in low voices, while I sat where I had been bidden, in a chair close to the railing. Once or twice the man with the star glanced at me, and then, presently, they all looked at me, and I couldn't distinguish one face from another. My head was whirling so with excitement I felt as if I were living in a dream. Yet when the man with the star began speaking I heard him with curious distinctness. "All that is necessary for you to do, Miss Fenwick, is to tell me whether you recognize the person you saw this morning."
