Weldon arrived on schedule early the following morning, and commenced his examination of the accounts of the First National, as was his habit. As soon as Todd knew that he was in town he took up his position outside the offices of the Central Trust, selecting a vantage point which would give him a clear view of both entrances of the bank. "Possibly," he argued to himself, "I am a damn fool. But just the same, I have a mighty well-defined hunch that Mr. Rockwell isn't on the level, and I ought to find out pretty soon." Then events began to move even quicker than he had hoped. The first thing he noted was that Jafferay, one of the bookkeepers of the C. T. C., slipped out of a side door of the bank and dropped a parcel into the mail box which stood beside the entrance. Then, a few minutes later, a messenger came out and made his way up the street to the State National, where--as Todd, who was on his heels--had little trouble in discovering--he cashed a cashier's check for one hundred and fifty thousand dollars, returning to the Central Trust Company with the money in his valise. "Of course," Todd reasoned, "Rockwell may be ignorant of the fact that Weldon doesn't usually get around to the State National until he has inspected all the other banks. Hence the check will have already gone to the clearing house and will appear on the books merely as an item of one hundred and fifty thousand dollars due, rather than as a check from the Central Trust. Yes, he may be ignorant of the fact--but it does look funny. Wonder what that bookkeeper mailed?" Working along the last line of reasoning, the government operative stopped at the post office long enough to introduce himself to the postmaster, present his credentials, and inquire if the mail from the box outside the Central Trust Company had yet been collected. Learning that it had, he asked permission to inspect it. "You can look it over if you wish," stated the postmaster, "but, of course, I have no authority to allow you to open any of it. Even the Postmaster-General himself couldn't do that." "Certainly," agreed Todd. "I merely want to see the address on a certain parcel and I'll make affidavit, if you wish, that I have reason to suppose that the mails are being used for illegal purposes." "That won't be necessary. We'll step down to the parcel room and soon find out what you want." Some five minutes later Todd learned that the parcel which he recognized--a long roll covered with wrapping paper, so that it was impossible to gain even an idea of what it contained--was addressed to Jafferay, the bookkeeper, at his home address. "Thanks! Now if you can give me some idea of when this'll be delivered I won't bother you any more. About five o'clock this afternoon? Fine!" and the man from Washington was out of the post office before anyone could inquire further concerning his mission.
