Next morning, when Herb Kivil opened the vault, he took one look and uttered one strangled cry. As Emanuel straightened up from the mail he was sorting, and as Mr. Blair stepped in off the street, out from between the iron doors staggered Herb Kivil, white as a sheet and making funny sounds with his mouth. The vault was empty—stripped of cash on hand; stripped of the Great Western Company's big deposit; stripped of every scrap of paper money; stripped of everything except the bank books and certain securities—in a word, stripped of between eighteen and nineteen thousand dollars, specie and currency. For the thief, whoever he might be, there was one thing to be said—he had an instinct for thoroughness in his make-up.

To say that the news, spreading with a most miraculous rapidity, made the town hum like a startled hive, is to state the case in the mildest of descriptive phrases. On the first alarm, the chief of police, accompanied by a good half of the day force, came at a dogtrot. Having severely questioned the frightened negro janitor, and examined all the doors and windows for those mysterious things known as clews, the chief gave it as his deliberate opinion that the robbery had been committed by some one who had means of access to the bank and its vault.

Inasmuch as there was about the place no evidence of forcible entry, and inasmuch as the face of the vault was not so much as scratched, and inasmuch, finally, as the combination was in perfect order, the population at large felt constrained to agree that Chief Henley had deduced aright. He took charge of the premises for the time being, Mr. Blair having already wired to a St. Louis detective agency beseeching the immediate presence and aid of an expert investigator.

It came out afterward that privily Mr. Blair suggested an immediate arrest, and gave to Henley the name of the person he desired to see taken into custody. But the chief, who was good-hearted—too good-hearted for his own good, some people thought—demurred. He stood in a deep and abiding awe of Mr. Blair. But he did not want to make any mistakes, he said. Anyhow, a big-city sleuth was due before night.. Would not Mr. Blair consent to wait until the detective had arrived and made his investigation? For his part, he would guarantee that the individual under suspicion did not get away. To his postponement of the decisive step Mr. Blair finally agreed.

On the afternoon train over the Short line the expert appeared, an inscrutable gentleman named Fogarty with a drooping red moustache and a brow heavily wrinkled. This Mr. Fogarty first conferred briefly with Mr. Blair and with Chief Henley. Then, accompanied by these two and trailed by a distracted group of directors of the bank, he made a careful survey of the premises from the cellar coal hole to the roof scuttle, uttering not a single word the while. His manner was portentous. Following this he asked for a word in private with the head of the rifled institution.

Leaving the others clustered in a group outside, he and Mr. Blair entered Mr. Blair's office. Mr. Fogarty closed the door and faced Mr. Blair.

“This here,” said Mr. Fogarty, “was what we call an inside job. Somebody here in this town—somebody who knew all there was to know about your bank—done it. Now, who do you suspicion?”

Lowering his voice, Mr. Blair told him, adding that only a deep sense of his obligations to himself and to his bank inspired him now to detail certain significant circumstances that had come to his personal attention within the past three weeks—or, to be exact, on a certain Wednesday morning in the latter part of September.

In his earlier movements Mr. Fogarty might have been deliberate; but once he made up his mind to a definite course of conduct he acted promptly. He came out of Mr. Blair's presence, walked straight up to Emanuel Moon, where Emanuel sat at his desk, and, putting his hand on Emanuel's shrinking shoulder, uttered the words:

“Young man, you're wanted! Put on your—”
