Except for the lone policeman who paused beneath the arc light at the Front Street intersection to make an entry in his patrol book, Bay Street was deserted. The fog which had come crawling in from the lake had filled the lower streets and was feeling its way steadily through the sleeping city, blurring the street lights. Its clammy touch darkened the stone facades of tall, silent buildings and left tiny wet beads on iron railing and grill work. Down towards the waterfront a yard-engine coughed and clanked about in the mist somewhere, noisily kicking together a string of box-cars, while at regular intervals the fog-horn over at the Eastern Gap bellowed mournfully into the night. After tucking away his book and rebuttoning his tunic the policeman lingered on the corner for a moment in the manner of one who has nothing to do and no place to go. He was preparing to saunter on when footfalls began to echo in the emptiness of the street and presently the figure of a young man grew out of the gray vapor-a young man who was swinging down towards the docks with the easy stride of an athlete.
