They were in animated debate when the door opened to admit somebody else. He had stepped in so quietly that he stood there a little while without being observed, smiling down at them with triumphant malice behind the mask he wore. Perhaps it was the black visor that was responsible for the Mephisto effect, since it hid all the face but the leering eyes. These, narrowed to slits, swept the room and came back to its occupants. He was a tall man and well-knit, dressed incongruously in up-to-date riding breeches and boots, in combination with the usual gray shirt, knotted kerchief and wide-brimmed felt hat of the horseman of the plains. The dust of the desert lay thick on him, without in the least obscuring a certain ribald elegance, a distinction of wickedness that rested upon him as his due. To this result his debonair manner contributed, though it carried with it no suggestion of weakness. To the girl who looked up and found him there he looked indescribably sinister. She half rose to her feet, dilated eyes fixed on him. “Good evenin’. I came to make sure y’u got safe home, Miss Messiter,” he said. The eyes of the two men clashed, the sheepman’s stern and unyielding, his cousin’s lit with the devil of triumph. But out of the faces of both men looked the inevitable conflict, the declaration of war that never ends till death. “I’ve been a heap anxious about y’u—couldn’t sleep for worrying. So I saddled up and rode in to find out if y’u were all right and to inquire how Cousin Ned was getting along.” The sheepman, not deigning to move an inch from his position, looked in silence his steady contempt. “This conversation sounds a whole lot like a monologue up to date,” he continued. “Now, maybe y’u don’t know y’u have the honor of entertaining the King of the Bighorn.” The man’s brown hand brushed the mask from his eyes and he bowed with mocking deference. “Miss Messiter, allow me to introduce myself again—Ned Bannister, train robber, rustler, kidnapper and general bad man. But I ain’t told y’u the worst yet. I’m cousin to a sheepherder’ and that’s the lowest thing that walks.” He limped forward a few steps and sat down. “Thank you, I believe I will stay a while since y’u both ask me so urgent. It isn’t often I meet with a welcome so hearty and straight from the heart.” It was not hard to see how the likeness between them contributed to the mistake that had been current concerning them. Side by side, no man could have mistaken one for the other. The color of their eyes, the shade of hair, even the cut of their features, were different. But beneath all distinctions in detail ran a family resemblance not to be denied. This man looked like his cousin, the sheepman, as the latter might have done if all his life he had given a free rein to evil passions. The height, the build, the elastic tread of each, made further contributions to this effect of similarity.
