In the murk of a foggy morning a row-boat moved steadily down stream. Two pairs of oars moved as one, for the rowers were skilled watermen. They kept to the Surrey shore, following the slightly irregular course imposed by the vital necessity of keeping to the unrevealing background formed by moored barges. Somewhere in the east the sun was rising, but the skies were dark and thick; lamps burnt on river and shore. Billingsgate Market was radiant with light, and over the wharves where cargo boats were at anchor white arc lights stared like stars. The river was waking; the “chuff-chuff” of donkey engines, the rattle and squeak of swaying derricks, the faint roar of chains running through came to the men in the skiff. They were clear of a long barge line, and the nose of the boat was turned to the northern shore, when on the dark background grew a darker object. The stroke rower jerked round his head and saw the lines of the launch which lay across his course, and dropped his oars. “Wade!” he grunted. Out of the blackness came a cheerful hail.
