In the German system there were five or six names to be remembered. Count von Bernstorff, the German Ambassador and chief plotter; Dr. Heinrich Albert, his assistant and treasurer; Franz von Rintelen, reported to be a near relative to the Kaiser; Captain Franz von Papen, the military attache; and his partner, Captain Boy-Ed, the naval attache. From this group at the top, the lines spread down, through business men, doctors, editors, clerks, butlers, and every rank and class in America. "Big Bill" Flynn, for many years the clever chief of the Secret Service, said that he thought there were 250,000 men and women in this country who were working for Germany. Sad to say, not all of them were German by birth; a few, the most dangerous, were native Americans, although they were Germans at heart. Everywhere, in the most unexpected places, these German agents were found, always busily carrying out their orders with regular German blindness, and never questioning or knowing anything about the hideous acts of their superiors. The German machine was, in short, like a huge wheel, with the brains at the hub. The United States fought this contemptible creation with several weapons. The Secret Service was of course the most active; but it was very greatly helped by the Department of Justice, the Naval Intelligence, and the Military Intelligence, as well as by the police departments in the various cities. In fact, one of the greatest troubles at times was that too many agencies would be working on the same case. They stepped on each other's heels. All these branches grew in size during the war, but especially the Naval and Military Intelligence offices. As early as January, 1916, patriotic citizens were quietly serving their government, all unknown even to their own friends, and were collecting pieces of information and hints here and there that, in the end, were of great value. If the Germans had spies in every nook and cranny of our nation, so did we--business men, secretaries, cooks, doctors, and laborers. The Secret Service was everywhere. Again and again, when some devoted German was busily doing his duty to his Fatherland, an American Secret Service agent would lay a hand on his shoulder and show him a ticket to a prison camp. And then, so curious is the German way of thinking, nine times out of ten the German, intensely surprised and very cross at being caught in the act, would insist that he was doing nothing, and that he had a perfect right to do it!
