"There," he continued, after reading the advertisement aloud, "that is the notice which I inserted after finding the money which you say is counterfeit."

"Where did you find it?"

"In the Pennsylvania station, night before last. I had just come in from New York, and chanced to see the envelope lying under one of the rows of seats in the center of the waiting room. It attracted my attention, but when I examined it I was amazed to find that it contained one hundred and fifty fifty-dollar bills, all apparently brand new. Naturally, I didn't care to part with the money unless I was certain that I was giving it up to the rightful owner, so I carried it with me to the hotel and advertised the loss at once.

"The next afternoon I went out to the track and found, when it was too late, that the only money I had with me was that contained in the envelope. I used a couple of the bills, won, and, being superstitious, decided to continue betting with that money. That's the reason I used it this afternoon. Come to think of it, you won't find the original five thousand dollars in my room. Part of it is the money which I received at the track and which I replaced in order to make up the sum I found. But most of the bills are there."

"You said," remarked the chief, striking another tack, "that your name is Thurene and that you live in New Haven. What business are you in?"

"Stationery. You'll find that my rating in Bradstreet's is excellent, even though my capital may not be large. What's more"—and here the man's voice became almost aggressive—"any bank in New Haven and any member of the Chamber of Commerce will vouch for me. I've a record of ten years there and some ten in Lowell, Mass., which will bear the closest possible inspection."

And he was right, at that.

In the first place, a search of his room at the hotel brought to light a large official envelope containing just the sum of money he had mentioned, counterfeit bills and real ones. Secondly, a wire to New Haven elicited the information that "Robert J. Thurene, answering to description in inquiry received, has operated a successful stationery store here for the past ten years. Financial standing excellent. Wide circle of friends, all of whom vouch for his character and integrity."

When this wire was forwarded to Washington, the chief having returned to headquarters, Spencer Graham received a hurry-up call to report in the main office. There he was informed that he was to take charge of the Thurene case and see what he could find out.

"I don't have to tell you," added the chief, "that it's rather a delicate matter. Either the man is the victim of circumstances—in which case we'll have to release him with profound apologies and begin all over again—or he's a mighty clever crook. We can't afford to take any chances. The case as it finally stands will have to be presented in court, and, therefore, must be proof against the acid test of shrewd lawyers for the defense, lawyers who will rely upon the newspaper advertisement and Thurene's spotless record as indications of his innocence."
