A maniac, surely; yet a maniac with strange powers. For the graphs of the radio direction-finders showed a curve. And when they were assembled the reading could only mean that the instrument that had sent the threat had moved over fifty miles during the few minutes of its sending. This, I think, was what brought the order to vacate the big domed building in Washington. Of course the Capitol Building had been searched; there was not a nook nor corner from roof to basement but had been gone over in search of an explosive machine. And now it was empty, and a guard of soldiers made a solid cordon surrounding it. No one could approach upon the ground; and, above, a series of circling patrol-planes, one squadron above another, guarded against approach by air. With such a defense the Capitol and its grounds seemed impregnable. My watch said 11:59; I held it in my hand and watched the seconds tick slowly by. The city was hushed; it seemed that no man was so much as breathing ... 11:59 :60!--and an instant later I heard the shriek of something that tore the air to screaming fragments. I saw it as it came on a straight, level line from the east; a flash like a meteor of glistening white. It passed beneath the planes, that were motionless by contrast, drove straight for the gleaming Capitol dome, passed above it, and swept on in a long flattened curve that bent outward and up. It was gone from my sight, though the shrieking air was still tearing at my ears, when I saw the great building unfold. Time meant nothing; my racing mind made slow and deliberate the explosion that lifted the roofs and threw the walls in dusty masses upon the ground. So slow it seemed!--and I had not even seen the shell that the white meteor-ship had fired. Yet there was the beautiful building, expanding, disintegrating. It was a cloud of dust when the concussion reached me to dash me breathless to the earth.... * * * * * The white meteor was the vehicle of "Paul," the dictator. From it had come the radio message whose source had moved so swiftly. I saw this all plainly. There was a conference of high officials at the War Department Building, and the Secretary summed up all that was said: "A new form of air-flight, and a new weapon more destructive than any we have known! That charge of explosive that was fired at the Capitol was so small as to be unseen. We can't meet it; we can only fight. Fight on till the end." A message came in as we sat there, a message to the Commander-in-Chief who had come over from the White House under military guard. "Surrender!" it demanded; "I have shown you my power; it is inexhaustible, unconquerable. Surrender or be destroyed; it is the dawn of a new day, the day of the Brotherhood of Man. Let bloodshed cease. Surrender! I command it! Paul."
