“Then within a week, in walked the manager of the Mozambique Hotel—­he had been stung with the fake International Express money-order—­same Englishman, too, I believe.”

“And you have no trace of him?” asked Kennedy eagerly.

“We had him under arrest once—­we thought.  A general alarm was sent out, of course, to all the banks and banking-houses.  But the man was too clever to turn up in that way again.  In one gambling-joint which women frequent a good deal, a classy dame who might have been a duchess or a—­well, she was a pretty good loser and always paid with hundred-dollar bills.  Now, you know women are not good losers.  Besides, the hundred-dollar-bill story had got around among the gambling-houses.  This joint thought it worth taking a chance, so they called me up on the ’phone, extracted a promise that I’d play fair and keep O’Connor from raiding them, but wouldn’t I please come up and look over the dame of the yellow bills?  Of course I made a jump at it.  Sure enough, they were the same counterfeits.  I could tell because the silk threads were drawn in with coloured ink.  But instead of making an arrest I decided to trail the lady.

“Now, here comes the strange part of it.  Let me see, this must have been over two months ago.  I followed her out to a suburban town, Riverwood along the Hudson, and to a swell country house overlooking the river, private drive, stone gate, hedges, old trees, and all that sort of thing.  A sporty-looking Englishman met her at the gate with one of those big imported touring-cars, and they took a spin.

“I waited a day or so, but nothing more happened, and I began to get anxious.  Perhaps I was a bit hasty.  Anyhow I watched my chance and made an arrest of both of them when they came to New York on a shopping expedition.  You should have heard that Englishman swear.  I didn’t know such language was possible.  But in his pocket we found twenty more of those hundred-dollar bills—­that was all.  Do you think he owned up?  Not a bit of it.  He swore he had picked the notes up in a pocketbook on the pier as he left the steamer.  I laughed.  But when he was arraigned in court he told the magistrate the same story and that he had advertised his find at the time.  Sure enough, in the files of the papers we discovered in the lost-and-found column the ad., just as he claimed.  We couldn’t even prove that he had passed the bills.  So the magistrate refused to hold them, and they were both released.  But we had had them in our power long enough to take their finger-prints and get descriptions and measurements of them, particularly by this new ’portrait parle’ system.  We felt we could send out a strange detective and have him pick them out of a crowd—­you know the system, I presume?”

Kennedy nodded, and I made a mental note of finding out more about the “portrait parle” later.

Burke paused, and O’Connor prompted, “Tell them about Scotland Yard, Tom.”
