So much--and also that her own name was Meliar-Ann and her mother kept a sailor's lodging-house--the small creature told us, still trotting by our side, until we found ourselves walking alongside a low wall over which we inhaled strong odours of the sea and of longshore sewage, and spied the riding-lights of the harbour looming through the fog. At the end of this we came to the high walls of a row of houses, all very quiet and black to the eye, except that here and there a chink of light showed through a window-shutter or the sill of a street-door. Throughout that long walk I had an uncanny sensation as of being led through a town bewitched, hushed, but wakeful and expectant of something. . . . I can get no nearer to explaining. We must have passed a score of taverns at least; of that I have assured myself by many a later exploration of Portsmouth: and in those days a Portsmouth tavern never closed day or night, save for the death of a landlord, nor always for that. But to-night a murmur at most distinguished it from the other houses in the street. Meliar-Ann solved the puzzle for us, with a wise nod of the head-- "There's a press out; or elst they're expecting one," she said. I heard a distant clock chiming for midnight as we followed her along this row of houses. Ahead of us a door opened, throwing a thin line of light upon the roadway, and was closed again softly, after the person within had stood listening (as it seemed to me) for five seconds or so. Meliar-Ann started suddenly in front of us, spreading her arms out, then slowly backwards, and so motioning us to halt under the shadow of the wall. Obeying, we saw her tiptoe forwards, till, coming to the door which had just been closed, she crept close and tapped on it softly, yet in a way that struck me as being deliberate. Afterwards, thinking it over, I felt pretty sure that the child knocked by code.
