“"You don't understand," he said, "who I am or what I am. I'll show you. By Heaven! I'll show you." Then he put his open palm over his face and withdrew it. The centre of his face became a black cavity. "Here," he said. He stepped forward and handed Mrs. Hall something which she, staring at his metamorphosed face, accepted automatically. Then, when she saw what it was, she screamed loudly, dropped it, and staggered back. The nose—it was the stranger's nose! pink and shining—rolled on the floor.Then he removed his spectacles, and everyone in the bar gasped. He took off his hat, and with a violent gesture tore at his whiskers and bandages. For a moment they resisted him. A flash of horrible anticipation passed through the bar. "Oh, my Gard!" said some one. Then off they came.It was worse than anything. Mrs. Hall, standing open-mouthed and horror-struck, shrieked at what she saw, and made for the door of the house. Everyone began to move. They were prepared for scars, disfigurements, tangible horrors, but nothing! The bandages and false hair flew across the passage into the bar, making a hobbledehoy jump to avoid them. Everyone tumbled on everyone else down the steps. For the man who stood there shouting some incoherent explanation, was a solid gesticulating figure up to the coat-collar of him, and then—nothingness, no visible thing at all!”
