Of course, when the war broke in August, 1914, the Hamburg-American line didn't have any further official use for Weimar. Their ships were tied up in neutral or home ports and Herr Paul was out of a job--for at least ten minutes. But he was entirely too valuable a man for the German organization to overlook for longer than that, and von Papen, in Washington, immediately added him to his organization--with blanket instructions to go the limit on any dirty work he cared to undertake. Later, he worked for von Bernstorff; Doctor Dumba, the Austrian ambassador; and Doctor von Nuber, the Austrian consul in New York--but von Papen had first claim upon his services and did not hesitate to press them, as proven by certain entries in the checkbook of the military attache during the spring and summer of 1915. Of course, it didn't take the Secret Service and the men from the Department of Justice very long to get on to the fact that Weimar was altogether too close to the German embassy for the safety and comfort of the United States government. But what were they to do about it? We weren't at war then and you couldn't arrest a man merely because he happened to know von Papen and the rest of his precious companions. You had to have something on him--something that would stand up in court--and Paul Weimar was too almighty clever to let that happen. When you remember that it took precisely one year to land this Austrian--one year of constant watching and unceasing espionage--you will see how well he conducted himself. And the government's sleuths weren't the only ones who were after him, either. Captain Kenney, of the New York Police Force, lent mighty efficient aid and actually invented a new system of trailing in order to find out just what he was up to. In the old days, you told a man to go out and follow a suspect and that was all there was to it. The "shadow" would trail along half a block or so in the rear, keeping his man always in view, and bring home a full account of what he had done all day. But you couldn't do that with Weimar--he was too foxy. From what some of the boys have told me, I think he took a positive delight in throwing them off the scent, whether he had anything up his sleeve or not.
