A faint light burned in the rear of the lower floor, while in the front room upstairs a fire was evidently burning in an open grate, the rest of the house being in darkness.

Presently a man's figure, tall and well formed, could be seen pacing up and down the room, appearing, vanishing, and reappearing in the wavering firelight.

For nearly an hour he continued his perambulation, his hands clasped behind him as though absorbed in deep thought.

At last, arousing himself from his revery, the man looked at his watch and vanished, reappearing ten minutes later at the front door, in the usual fur coat and cap, and, descending the steps, turned towards town and proceeded leisurely down the street, Mr.Rosenbaum following at some distance, but always keeping him in view and gradually diminishing the distance between them as the thoroughfare became more crowded, till they were nearly opposite each other.
Finally, the man paused before a restaurant and, turning, looked carefully up and down the street.

For the first time he observed Mr.Rosenbaum and seemed to regard him with close attention, but the latter gentleman was absorbed in the contemplation of an assortment of diamonds and various gems displayed in a jeweller's window, directly opposite the restaurant.
