Among the passengers to detrain was a man in a long black coat. The high collar was up. The man wore a derby hat, well down upon his head, after the English mode. An English kitbag, battered and scarred, swung heavily from his hand. Away toward the far end of the platform there appeared a shadowy patch in the fog. It grew and presently took upon itself the shape of a man. For one so short and squat and thick his legs possessed remarkable agility, for he reached the street just as the other man stopped at the side of a taxicab. Sixteen thousand miles, always eastward, on horses, camels, donkeys, trains, and ships; the fog would serve as an impenetrable cloak. he was within three hours of his ultimate destination! He knew all about great cities. An hour after he left the train, if he so willed, he could lose himself for all time.
