"Many thanks, Mr. Langford, for your society," he said, with old-fashioned courtesy. "I wish you a good-evening." "Good-evening," I replied, putting out my hand. But he either did not see it or did not choose to see it, and, slightly lifting his hat, stepped out upon the platform. Having done this, he moved slowly away and mingled with the departing crowd. Leaning forward to watch him out of sight, I trod upon something which proved to be a cigar-case. It had fallen, no doubt, from the pocket of his waterproof coat, and was made of dark morocco leather, with a silver monogram upon the side. I sprang out of the carriage just as the guard came up to lock me in. "Is there one minute to spare?" I asked, eagerly. "The gentleman who travelled down with me from town has dropped his cigar-case; he is not yet out of the station." "Just a minute and a half, sir," replied the guard. "You must be quick." I dashed along the platform as fast as my feet could carry me. It was a large station, and Mr. Dwerrihouse had by this time got more than half-way to the farther end. I, however, saw him distinctly, moving slowly with the stream. Then, as I drew nearer, I saw that he had met some friend, that they were talking as they walked, that they presently fell back somewhat from the crowd and stood aside in earnest conversation. I made straight for the spot where they were waiting. There was a vivid gas-jet just above their heads, and the light fell full upon their faces. I saw both distinctly--the face of Mr. Dwerrihouse and the face of his companion. Running, breathless, eager as I was, getting in the way of porters and passengers, and fearful every instant lest I should see the train going on without me, I yet observed that the new-comer was considerably younger and shorter than the director, that he was sandy-haired, mustachioed, small-featured, and dressed in a close-cut suit of Scotch tweed. I was now within a few yards of them. I ran against a stout gentleman, I was nearly knocked down by a luggage-truck, I stumbled over a carpet-bag; I gained the spot just as the driver's whistle warned me to return. To my utter stupefaction, they were no longer there. I had seen them but two seconds before--and they were gone! I stood still; I looked to right and left; I saw no sign of them in any direction. It was as if the platform had gaped and swallowed them. "There were two gentlemen standing here a moment ago," I said to a porter at my elbow; "which way can they have gone?" "I saw no gentlemen, sir," replied the man. The whistle shrilled out again. The guard, far up the platform, held up his arm, and shouted to me to "come on!" "If you're going on by this train, sir," said the porter, "you must run for it." I did run for it, just gained the carriage as the train began to move, was shoved in by the guard, and left, breathless and bewildered, with Mr. Dwerrihouse's cigar-case still in my hand.
