But right there the trail stopped.

No one appeared to know whether the Austrian was in New York, or the United States, for that matter, though one informant did admit that it was quite probable.

"Buch and the big fellow had a row the last time over," was the information Maxwell secured at the cost of a few drinks. "Something about some money that Weimar is supposed to have owed him—fifteen dollars or some such amount. I didn't hear about it until afterward, but it appears to have been a pretty lively scrap while it lasted. Of course, Buch didn't have a chance against the big fellow—he could handle a bull. But the young Austrian threatened to tip his hand—said he knew a lot of stuff that would be worth a good deal more money than was coming to him, and all that sort of thing. But the ship docked the next day and I haven't seen or heard of him since."

The idea of foul play at once leaped into Maxwell's mind, but investigation of police records failed to disclose the discovery of anybody answering to the description of George Buch and, as Captain Kenney pointed out, it is a decidedly difficult matter to dispose of a corpse in such a way as not to arouse at least the suspicions of the police.

As a last resort, about the middle of September, Maxwell had a reward posted on the bulletin board of every police station in New York and the surrounding country for the "apprehension of George Buch, Austrian, age about twenty-four. Height, five feet eight inches. Hair, blond. Complexion, fair. Eyes, blue. Sandy mustache."

As Captain Kenney pointed out, though, the description would apply to several thousand men of German parentage in the city, and to a good many more who didn't have a drop of Teutonic blood in their veins.

"True enough," Maxwell was forced to admit, "but we can't afford to overlook a bet—even if it is a thousand-to-one shot."

As luck would have it, the thousand-to-one shot won!

On September 25, 1917, Detective Gary returned to headquarters, distinctly crestfallen. Weimar had given him the slip.

In company with another man, whom the detective did not know, the Austrian had been walking up Sixth Avenue that afternoon when a machine swung in from Thirty-sixth Street and the Austrian had leaped aboard without waiting for it to come to a full stop.
