Some initials had been carved on the stock and she examined them, making them out finally as "B. D."--Doubler's. Examining the weapon she found an empty shell in the chamber, and she nearly dropped the rifle when the thought struck her that perhaps Doubler had been shot with it. She set it down quickly, shuddering, and for diversion walked to her pony, examining the injured leg and rubbing it, the pony nickering gratefully. Returning to the cabin she sat for a long time on the step, but she did not again take up the rifle. Several times while she sat on the step she heard Doubler moan, and once she got up and went to him, again bathing his wound, but returning instantly to the door step, for she could not bear the silence of the interior. Suddenly remembering Dakota's vest and the black leather memoranda which had dropped from one of the pockets, she got up again and went to the bench where she had laid the garment, taking out the book and regarding it with some curiosity. There was nothing on the cover to suggest what might be the nature of its contents--time had worn away any printing that might have been on it. She hesitated, debating the propriety of an examination, but her curiosity got the better of her and with a sharp glance at Doubler she turned her back and opened the book. Almost the first object that caught her gaze was a piece of paper, detached from the leaves, with some writing on it. The writing seemed unimportant, but as she turned it, intending to replace it between the leaves of the book, she saw her father's name, and she read, holding her breath with dread, for fresh in her mind was Duncan's charge that her father had entered into an agreement with Dakota for the murder of Doubler. She read the words several times, standing beside the bench and swaying back and forth, a sudden weakness gripping her. "One month from to-day"--ran the words--"I promise to pay to Dakota the sum of six thousand dollars in consideration of his rights and interest in the Star brand, provided that within one month from date he persuades Ben Doubler to leave Union County." Signed: "David Dowd Langford." There it was--conclusive, damning evidence of her father's guilt--and of Dakota's! How cleverly that last clause covered the evil intent of the document! Sheila read it again and again with dry eyes. Her horror and grief were too great for tears. She felt that the discovery of the paper removed the last lingering doubt, and though she had been partially prepared for proof, she had not been prepared to have it thrust so quickly and convincingly before her.
