Seven months ago, while working upon a criminal case, I had made the acquaintance of this gentleman at a thieves' tavern, down in the slums. I was, of course, safely disguised at the time, and in an assumed character; hence I had no fear of being recognized now.

"Dimber[A] Joe" had been doing Government service, in consequence of his connection with a garroting escapade, and had but just been released from "durance vile." His hair was then somewhat shorter than was becoming; his face was unshaven, and his general appearance that of a seedy, hard-up rascal. The person before me wore his hair a little longer than the ordinary cut; his face was clean shaven, his linen immaculate, and his dress a well-made business suit, such as a merchant or banker abroad might wear. But it was Dimber Joe.

Evidently fortune had dropped a few, at least, of her favors at Dimber Joe's feet, but it was quite safe to conjecture that some one was so much the worse off for his present prosperity.

What new mischief was on foot? for it was hardly likely that Dimber Joe, late the associate of river thieves, was now undertaking an honest journey.

I resolved to watch him closely while our way was the same, and to give my Chief an account of our meeting, together with a description of Joe's "get up," at the first opportunity.

Accordingly, I remained in the smoking car during the entire journey, but no suspicious or peculiar movement, on the part of Dimber Joe, rewarded my vigilance, until the brakeman called Trafton, and we pulled into that station.

Then Dimber Joe arose, stretched himself, flung a linen duster across his arm, and, swinging in his hand a small valise, quitted the car, stepped down upon the shadowy platform just ahead of me; and, while I was looking about for Carnes, vanished in the darkness.

"Well, Carnes," I said, when we were once more alone in our room at the hotel, "what has happened? Have you seen anything that looks like a detective?"
