Dick looked down at himself. For a moment he had the illusion that he was a head and a trunk, floating in the air. His lower limbs had become invisible, except for patches of trousering that seemed to drift through space. The mob in the room had fallen back gaping at him in horror.
Then Dick understood. It was the invisible garment that had coiled itself about him. He tore it from him and became visibly a man once more.
Shouts from another room! A surging movement of the crowd toward it. The muffled sounds of an automatic pistol, fitted with a silencer! Then screams:
"The devils are in there! They're murdering the soldiers!"
There followed a panic-stricken rush, more muffled firing, and then the sharp roar of rifles, and the fall of plaster. Some one was bawling the President's name. The rooms became a mass of milling human beings, lost to all self-control.
A bedlam of noise and struggle. Men fought with one another blindly, cursing soldiers fired promiscuously among the mob, riddling the walls, stabbing at the air. The plaster was falling in great chunks everywhere, filling the rooms with a heavy white cloud, in which all choked and struggled. The yells of the civilian mob below, struggling helplessly in the packed crowd that wedged the great stairway, made babel. Outside the White House a dense mob that filled the lawns was yelling back, and struggling to gain admittance. Suddenly the lights went out.
"They've cut the wires!" rose a wild, wailing voice. "The devils have cut the wires! Kill them! Kill everybody!"
His cry ended in a gurgle. Somewhere in that dark hell a struggle was going on, a well defined struggle, different from the random, aimless battling of the half-crazed soldiers and the civilians. President Hargreaves was still within the walls of the White House, it was known; it was physically impossible for him to have been carried away when every foot of space was packed. And through that darkness the invisible assailants were edging him, foot by foot, toward the outside.
