Here and Hereafter by Barry Pain

In the billiard-room of the Cabinet Club, shortly after midnight, two men had just finished a game. A third had been watching it from the lounge at the end of the room. The winner put up his cue, slipped on his coat, and with a brief "Good-night" passed out of the room. He was tall, dark, clean-shaven and foreign in appearance. It would not have been easy to guess his nationality, but he did not look English.

The loser, a fair-haired boy of twenty-five, came over to the lounge and dropped down by the side of the elderly man who had been watching the billiards.
