"Scully took up his paper and for a long time remained immersed in matters which were extraordinarily remote from him. The lamp burned badly, and once he stopped to adjust the wick. The newspaper as he turned from page to page rustled with a slow and comfortable sound. Then suddenly he heard three terrible words: "You are cheatin'!"
"Such scenes often prove that there can be little of dramatic import in environment. Any room can present a tragic front; any room can be comic. This little den was now hideous as a torture-chamber. The new faces of the men themselves had changed it upon the instant. The Swede held a huge fist in front of Johnnie's face, while
the latter looked steadily over it into the blazing orbs of his accuser. The Easterner had grown pallid; the cowboy's jaw had dropped in that expression of bovine amazement which was one of his important mannerisms. After the three words, the first sound in the room was made by Scully's paper as
it floated forgotten to his feet. His spectacles had also fallen from his nose, but by a clutch he had saved them in air. His hand, grasping the spectacles, now remained poised awkwardly and near his shoulder. He stared at the card-players." (
