"His success in getting money from me led him into deep waters. He victimized others, who threatened prosecution. Realizing that matters could not go on as they were going, I told my brother that I would take up the claims against him and give him one hundred thousand dollars, on certain conditions. Those conditions were that he was to renounce all claim to his little stepdaughter, and that I was to have sole care of her. He was to go to some distant part of the country and change his name and let the world forget that such a creature as Willard Sargent ever existed.

"My brother was forced to agree to the terms laid down. The university trustees were threatening him with expulsion. He resigned and came out here. He married an Indian woman, and, as I understand it, killed her by the same cold-hearted, deliberately cruel treatment that had brought about the death of his first wife.

"Meantime Willard's stepdaughter, who was none other than Helen, was brought up by a lifelong friend of mine, Miss Scovill, at her school for girls in California. The loving care that she was given can best be told by Helen. I did not wish the girl to know that she was dependent upon her uncle for support. In fact, I did not want her to learn anything which might lead to inquiries into her babyhood, and which would only bring her sorrow when she learned of her mother's fate. My brother, always clever in his rascalities, learned that Helen knew nothing of my existence. He sent her a letter, when Miss Scovill was away, telling Helen that he had been crippling himself financially to keep her in school, and now he needed her at this ranch. Before Miss Scovill had returned, Helen, acting on the impulse of the moment, had departed for my brother's place. Miss Scovill was greatly alarmed, and sent me a telegram. As soon as I received word, I started for my brother's ranch. I happened to have started on an automobile tour at the time, and figured that I could reach here as quickly by machine as by making frequent changes from rail to stage.

"When Helen arrived at the ranch, it can be imagined how the success of his scheme delighted Willis Morgan, as my brother was known here. He threatened her with the direst of evils, and declared he would drag her beneath the level of the poorest squaw on the Indian reservation. Fortunately she is a girl of spirit and determination. The Chinese servant was willing to help her to escape. She would have fled at the first opportunity, in spite of my brother's declaration that escape would be impossible, but it happened that, during the course of his boasting, her captor overstepped himself. He told her of my existence, and that I had really been the one who had kept her in school. He had managed to keep a thorough system of espionage in effect, so far as Miss Scovill and myself were concerned. He had known when she left San Francisco, and he also knew that I was coming, by automobile, to take Helen from the ranch. He laughed as he told her of my coming. All the ferocity of his nature blazed forth, and he told Helen that he intended to kill me at sight, and would also kill her.

"Desirous of warning me, even at risk of her own life, Helen mailed a letter to me at Quaking-Asp Grove, hoping to catch me before I reached that place. In this letter she warned me not to come to the ranch, as she felt that tragedy impended. Talpers held up the letter and read it, and thought to hold it as a club over Helen's head, showing that she knew something of the murder.

"I rode through Quaking-Asp Grove and White Lodge and the Indian agency at night. I had a breakdown after going past Talpers's store—a tire to replace. By the time I climbed the hill on the Dollar Sign road it was well along in the morning. I saw a man coming toward me on a white horse. It was my brother, Willard Sargent, or Willis Morgan. He looked much like me. The years seemed to have dealt with us about alike. I knew, as soon as I saw him, that he had come out to kill me. We talked a few minutes. I had stopped the car at his demand, and he sat in the saddle, close beside me. There is no need of going into the details of our conversation. He was full of reproaches. His later life had been more of a punishment for him than I had suspected. His voice was full of venom as he threatened me. He told me that Helen was at the ranch, but I would never see her. He had a sawed-off shotgun in his hand. I had no weapon. I made a quick leap at him and threw him from his horse. The shotgun fell in the road. I jumped for it just as he scrambled after it. I wrested the weapon from him. He tried to draw a revolver that swung in a holster at his hip. There was no chance for me to take that from him. It was a case of his life or mine. I fired the shotgun, and the charge tore away the lower part of his face.

"Strangely enough, I had no regret at what I had done. It was not that I had saved my own life—I had managed to intervene between Helen and a fate worse than death. I weighed matters and acted with a coolness that surprised me, even while I was carrying out the details that followed. It occurred to me that, because of our close resemblance to each other, it might be possible for me to pass myself off as my brother. I knew that he had lived the life of a recluse here, and that few people knew him by sight. We were dressed much alike, as I was traveling in khaki, and he wore clothes of that material. I removed everything from his pockets, and then I put my watch and checkbook and other papers in his pockets. I even went so far as to put my wallet in his inner pocket, containing bills of large denomination.

"I had heard that there was some dissatisfaction among certain young Indians on the reservation—that those Indians were dancing and making trouble in general. It seemed to me that such a situation might be made use of in some way. Why not drag my brother's body out on the prairie at the side of the road and stake it down? Suspicion might be thrown on the Indians. I had no sooner thought of the plan than I proceeded to carry it out. I worked calmly and quickly. There was no living thing in sight to cause alarm. I took a rawhide lariat, which I found attached to the saddle on the old white horse, and used it to tie my brother's ankles and wrists to tent-stakes which I took from my automobile.

"After my work was done, I looked it over carefully, to see that I had left nothing undone and had made no blunder in what I had accomplished. I obliterated all tracks, as far as possible. Although it had rained the night before, and there was mud in the old buffalo wallows and in the depressions in the road, the prairie where I had staked the body was dry and dusty.

"After I had arranged everything to my satisfaction, I mounted the old white horse and rode to the ranch, merely following the trail the horse had made coming out. When I arrived here and made myself known to Helen, you can imagine her joy, which soon was changed to consternation when she found what had been done. But my plan of living here and letting the world suppose that I was Willard Sargent, or Willis Morgan, seemed feasible. Wong was our friend from the first. We knew we could depend on his Oriental discretion. But we were not to escape lightly. Talpers's attitude was a menace until, through a fortunate set of circumstances, we managed to secure a compensating hold over him. Undoubtedly Talpers had been first on the scene after the murder. He had robbed my brother's body, and was caught in his ghoul-like act by his partner, Jim McFann. The half-breed believed Talpers when the trader told him that a watch was all he had found on the dead man. The later discovery that Talpers had deceived him, and had really taken a large sum of money from the body, led the half-breed to kill the trader.

"I decided to await the outcome of the trial. It would have been impossible for me to let Fire Bear or McFann go to prison, or perhaps to the gallows, for my deed. If either one, or both, had been convicted, I intended to make a confession. But matters seemed to work out well for us. The accused men were freed, and it seemed to be the general opinion that Talpers had committed the crime. Talpers was dead. There was no occasion for me to confess. I had thoughts of going away, quietly, to some place where I could begin life over again. Miss Scovill is in possession of a will making Helen my heir. This will could have been produced, and thus Helen would have been well provided for. I had kept in seclusion here, and had even feigned illness, in order that none might suspect me of being other than Willis Morgan. But if any one had seen me I do not believe the deception would have been discovered, so close is my resemblance to my brother. Always having been a passable mimic, I imitated my brother's voice. It was a voice that had often stirred me to wrath, because of its cold, cutting qualities. The first time I imitated my brother's voice, Wong came in from the kitchen looking frightened beyond measure. He thought the ghost of his old employer had returned to the ranch.

"But of what use is all such planning when destiny wills otherwise? A trifling incident—the rolling of a horse in the mud—brought everything about my ears. Yet I believe it is for the best. Nor do I believe your discovery to have been a mere matter of chance. Probably you were led by a higher force than mere devotion to duty. Truth must have loyal servitors such as you if justice is to survive in this world. I am heartily glad that you persisted in your search. I feel more at ease in mind and body to-night than I have felt since the day of the tragedy. Now if you will excuse me a moment, I will make preparations for giving myself up to the authorities—perhaps to higher authorities than those at White Lodge."

Sargent stepped into the adjoining room as he finished talking. Helen did not raise her head from the table. Something in Sargent's final words roused Lowell's suspicion. He walked quickly into the room and found Sargent taking a revolver from the drawer of a desk. Lowell wrested the weapon from his grasp.

"That's the last thing in the world you should do," said the Indian agent, in a low voice. "There isn't a jury that will convict you. If it's expiation you seek, do you think that cowardly sort of expiation is going to bring anything but new unhappiness to her out there?"

"No," said Sargent. "I give you my word this will not be attempted again."

* * * * *

Space meeting space—plains and sky welded into harmonies of blue and gray. Cloud shadows racing across billowy uplands, and sagebrush nodding in a breeze crisp and electric as only a breeze from our upper Western plateau can be. Distant mountains, with their allurements enhanced by the filmiest of purple veils. Bird song and the chattering of prairie dogs from the foreground merely intensifying the great, echoless silence of the plains.

Lowell and Helen from a ridge—their ridge it was now!—watched the changes of the panorama. They had dismounted, and their horses were standing near at hand, reins trailing, and manes rising and falling with the undulations of the breeze. It was a month after Sargent's confession and his surrender as the slayer of the recluse of the Greek Letter Ranch. As Lowell had prophesied, Sargent's acquittal had been prompt. His story was corroborated by brief testimony from Lowell and Helen. Citizens crowded about him, after the jury had brought in its verdict of "Not guilty," and one of the first to congratulate him was Jim McFann, who had been acquitted when he came up for trial for slaying Talpers. The half-breed told Sargent of Talpers's plan to kill Helen.

"I'm just telling you," said the half-breed, "to ease your mind in case you're feeling any responsibility for Talpers's death."

Soon after his acquittal Sargent departed for California, where he married Miss Scovill—the outcome of an early romance. Helen was soon to leave to join her foster parents, and she and Lowell had come for a last ride.

"I cannot realize the glorious truth of it all—that I am to come soon and claim you and bring you back here as my wife," said Lowell. "Say it all over again for me."

He was standing with both arms about her and with her face uptilted to his. No doubt other men and women had stood thus on this glacier-wrought promontory—lovers from cave and tepee.

"It is all true," Helen answered, "but I must admit that the responsibilities of being an Indian agent's wife seem alarming. The thought of there being so much to do among these people makes me afraid that I shall not be able to meet the responsibilities."

"You'll be bothered every day with Indians—men, women, and babies. You'll hear the thumping of their moccasined feet every hour of the day. They'll overrun your front porch and seek you out in the sacred precincts of your kitchen, mostly about things that are totally inconsequential."

"But think of the work in its larger aspects—the good that there is to be done."

Lowell smiled at her approvingly.

"That's the way you have to keep thinking all the time. You have to look beyond the mass of detail in the foreground—past all the minor annoyances and the red tape and the seeming ingratitude. You've got to figure that you're there to supply the needed human note—to let these people understand that this Government of ours is not a mere machine with the motive power at Washington. You've got to feel that you've been sent here to make up for the indifference of the outside world—that the kiddies out in those ramshackle cabins and cold tepees are not going to be lonely, and suffer and die, if you can help it. You've got to feel that it's your help that's going to save the feeble and sick—sometimes from their own superstitions. There's no reason why we can't in time get a hospital here for Indians, like Fire Bear, who have tuberculosis. We're going to save Fire Bear, and we can save others. And then there are the school-children, with lonely hours that can be lightened, and with work to be found for them in the big world after they have learned the white man's tasks. But there are going to be heartaches and disillusionments for a woman. A man can grit his teeth and smash through some way, unless he sinks back into absolute indifference as a good many Indian agents do. But a woman—well, dear, I dread to think of your embarking on a task which is at once so alluring and so endless and thankless."

Helen put her hand on his lips.

"With you helping me, no task can seem thankless."

"Well, then, this is our kingdom of work," said Lowell, with a sweep of his sombrero which included the vast reservation which smiled so inscrutably at them. "There's every human need to be met out there in all that bigness. We'll face it together—and we'll win!"

They rode back leisurely along the ridge and took the trail that led to the ranch. The house was closed, as Wong was at the agency, ready to leave for the Sargents' place in California. The old white horse, which Helen rode, tried to turn in at the ranch gate.

"The poor old fellow doesn't understand that his new home is at the agency," said Helen. "He is the only one that wants to return to this place of horrors."

"The leasers will be here soon," replied Lowell. "They are going to put up buildings and make a new place all told. The Greek letter on the door will be gone, but, no matter what changes are made, I have no doubt that people will continue to know it as Mystery Ranch."

THE END
