"They never do," replied Mr. Dwerrihouse; "they all know me, and of course I travel free."

"Blackwater! Blackwater!" cried the porter, running along the platform beside us as we glided into the station.

Mr. Dwerrihouse pulled out his deed-box, put his travelling-cap in his pocket, resumed his hat, took down his umbrella, and prepared to be gone.

"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.
