The mob had scattered with shrieks of terror, but a few bolder spirits remained in a thin circle about that fearful thing on the rug. Dick bent over the man, and felt the outlines of the writhing body. It was a man, apparently dressed in some sort of uniform, but this was covered, from the top of the head to the feet, with a sort of sheer silken garment, bifurcating below the waist, and resembling a cocoon. It seemed to appear and alternately to vanish. Dick seized the filmy stuff in his fingers, rent it, and stripped it away. Yells of terror and amazement broke from the throats of all. Instantly the thin circle of spectators had become reinforced by a struggling mass of men. The half-visible cocoon clung to Dick's body like spider webs. But the man who had been wearing it had sprung instantly into view beneath the cluster of electric lights. He was a fair-haired young fellow of about thirty years, his features white and set in the agony of death. He was dressed in a trim uniform of black, with silver braid, and on his shoulders were the insignia of a lieutenant. He opened his eyes, blue as the skies, and stared about him. He seemed to understand what had happened to him. "Dogs!" he muttered. Shrieks of fury answered him. The mob surged toward him as if to grind his face to pieces under their feet--and then recoiled, mouthing and gibbering. But it was at Dick that they were looking, not at the dying man. He raised himself upon one elbow with a mighty effort. "His Majesty the Invisible Emperor! Long be his reign triumphant!" he chanted. It was his last credo. The words broke from his lips accompanied by a torrent of red foam. His head dropped back, his body slipped down; he was gone. And no one seemed to observe his passing. They were all screaming and gibbering at Dick. "Rennell! Rennell!" yelled Stopford. "Where are you, Rennell? God, man, what's happened to your legs?" 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.
