To shatter at a single blow the most venerable of the routine precedents, the sensational thing chose for its colliding point with orderly system one of the oldest and most conservative of the city's banks: the Bayou State Security. At ten o'clock, following the precise habit of half a lifetime, Mr. Andrew Galbraith, president of the Bayou State, entered his private room in the rear of the main banking apartment, opened his desk, and addressed himself to the business of the day. Punctually at ten-five, the stenographer, whose desk was in the anteroom, brought in the mail; five minutes later the cashier entered for his morning conference with his superior; and at half-past the hour the president was left alone to read his correspondence. Being a man whose mental processes were all serious, and whose hobby was method, Mr. Galbraith had established a custom of giving himself a quiet half-hour of inviolable seclusion in which to read and consider his mail. During this sacred interval the stenographer, standing guard in the outer office, had instructions to deny his chief to callers of any and every degree. Wherefore, when, at twenty minutes to eleven, the door of the private office opened to admit a stranger, the president was justly annoyed. "Well, sir; what now?" he demanded, impatiently, taking the intruder's measure in a swift glance shot from beneath his bushy white eyebrows. The unannounced visitor was a young man of rather prepossessing appearance, a trifle tall for his breadth of shoulder, fair, with blue eyes and a curling reddish beard and mustache, the former trimmed to a point. So much the president was able to note in the appraisive glance--and to remember afterward. The caller made no reply to the curt question. He had turned and was closing the door. There was a quiet insistence in the act that was like the flick of a whip to Mr. Galbraith's irritation. "If you have business with me, you'll have to excuse me for a few minutes," he protested, still more impatiently. "Be good enough to take a seat in the anteroom until I ring. MacFarland should have told you." The young man drew up a chair and sat down, ignoring the request as if he had failed to hear it. Ordinarily Mr. Andrew Galbraith's temper was equable enough; the age-cooled temper of a methodical gentleman whose long upper lip was in itself an advertisement of self-control. But such a deliberate infraction of his rules, coupled with the stony impudence of the visitor, made him spring up angrily to ring for the watchman. The intruder was too quick for him. When his hand sought the bell-push he found himself looking into the muzzle of a revolver, and so was fain to fall back into his chair, gasping. "Ah-h-h!" he stammered. And when the words could be managed: "So that's it, is it?--you're a robber!"
