He was in civilian dress except for the forage-cap, which he had hastily picked up when we left the office. Its gold cord and crossed sabres gleamed under the lamp as he sharply turned the door-knob and entered the room. Even without that cap I by this time would have known his profession; he had that quick, springy, nervous walk and erect carriage so marked among the younger West-Pointers. My eyes followed him until he disappeared; so apparently did others. From the farther end of the gallery two dark forms rose from a sitting posture, and one of them came tiptoeing along towards the doorway. Our cab had halted near the steps at the end opposite them, and, despite our lights, the stealthily-moving figure seemed to pay no attention to us. Before I had time to conjecture what his object could be, the man crouched before the door, his hat pulled low over his forehead, and peered eagerly through the glass. Then he turned his head; gave a low whistle, and, almost at a run, the second figure, in slouch hat like the first and with overcoat pulled well up about his ears, hurried to his side; stooped; peered through, and shook his head. "Drive up there, quick!" I said. And, as hoof and wheel crunched through the gravel, the pair drew suddenly back; sprang noiselessly down the steps and in among the shrubbery out of my sight. Almost at the same instant Mr. Parker reappeared; took his seat beside me, and, before I could interpose, called out, "Drive on,--Lake End." And away we went, leaving the mysterious strangers in the dusk behind us. "Amory has not been seen there, nor beyond. There are two young sports in there who came in from Lake End half an hour ago, but they are both pretty full. The barkeeper said there were two more gentlemen who came out from town with another buggy earlier, but they had gone outside." "I saw them," answered I, "and they are bad characters of some kind. They stole up on tiptoe and peered after you as you went in, then sprang back out of sight as you came out. I wanted to tell you about them. They seemed waiting or watching for somebody." "Gamblers or 'cappers' probably. Fellows who lie in wait for drunken men with money and steer them into their dens,--fleece them, you know. The streets are full of them day and night." "Yes; but these men wore slouch hats and overcoats that muffled their faces, and they watched you so oddly. Why did they leap back as you came out?" "That was odd," said Mr. Parker, thoughtfully. "Could you see nothing of their faces?" "Nothing at all, except that the first man had a heavy dark moustache, and was tall and stoutly built; the other seemed young and slight; his face was hidden entirely." The aide-de-camp leaned out and looked back along the dark road; then drew in again. "No use to look," he said. "Even if they were to follow I could not see; their buggy has no lamps, our rig has to have them. Are you armed?" "No; I never carry anything."
