It was late. The August night was cool and sweet after a weary day of intense heat. The door was thrown wide open. It was good to feel the night air creeping into the stifling room. There was no light within; and without, nothing but the brilliant stars in the quiet, brooding sky. Williston was sitting just within the doorway. Mary, her hands clasped idly around her knees, sat on the doorstep, thoughtfully staring out into the still darkness. There was a stir.  
“Bedtime, little girl,” said Williston.
 
“Just a minute more, daddy. Must we have a light? Think how the mosquitoes will swarm. Let’s go to bed in the dark.”
 
“We will shut the door and next Summer, little girl, you shall have your screens. I promise you that, always providing, of course, Jesse Black leaves us alone.”
 
Had it not been so dark, Mary could have seen the wistful smile on the thin, scholarly face. But though she could not see it, she knew it was there. There had been fairer hopes and more generous promises in the past few years. They had all gone the dreary way of impotent striving, of bitter disappointment. There was little need of light for Mary to read her father’s thoughts.
 
“Sure, daddy,” she answered, cheerily. “And I’ll see that you don’t forget. As for Jesse Black, he wouldn’t dare with the Three Bars on his trail. Well, if you must have a light, you must,” rising and stretching her firm-fleshed young arms far over her head. “You can’t forget you were born in civilization, can you, daddy? I am sure I could be your man in the dark, if you’d let me, and I always turn your nightshirt right side out before hanging it on your bedpost, and your sheet and spread are turned down, and water right at hand. You funny, funny little father, who can’t go to bed in the dark.” She was rummaging around a shelf in search of matches. “Now, I have forgotten long since that I wasn’t born on the plains. It wouldn’t hurt me if I had misplaced my nightdress. I’ve done it,” with a gay little laugh. He must be cheered up at all costs, this buffeted and disappointed but fine-minded, high-strung, and lovable father of hers. “And I haven’t taken my hair down nights since—oh, since months ago, till—oh, well—so you see it’s easy enough for me to go to bed in the dark.”
 
Her hand touched the match box at last. A light flared out.
 
“Shut the door quick, dad,” she said, lighting the lamp on the table. “The skeeters’ll eat us alive.”
 
Williston stepped to the door. Just a moment he stood there in the doorway, the light streaming out into the night, tall, thoughtful, no weakling in spite of many failures and many mistakes. A fair mark he made, outlined against the brightly lighted room. It was quiet. Not even a coyote shrilled. And while he stood there looking up at the calm stars, a sudden sharp report rang out and the sacred peace of God, written in the serenity of still summer nights, was desecrated. Hissing and ominous, the bullet sang past Williston’s head, perilously near, and lodged in the opposite wall. At that moment, the light was blown out. A great presence of mind had come to Mary in the time of imminent danger.
 
“Good, my dear!” cried Williston, in low tones. Quick as a flash, the door was slammed shut and bolted just as a second shot fell foul of it.
 
“Oh, my father!” cried Mary, groping her way to his side.
 
“Hush, my dear! They missed me clean. Don’t lose your nerve, Mary. They won’t find it so easy after all.”
 
There had been no third shot. A profound silence followed the second report. There was no sound of horse or man. Whence, then, the shots? One man, maybe, creeping up like some foul beast of prey to strike in the dark. Was he still lurking near, abiding another opportunity?
 
It took but a moment for Williston to have the rifles cocked and ready. Mary took her own from him with a hand that trembled ever so slightly.
 
“What will you do, father?” she asked, holding her rifle lovingly and thanking God in a swift, unformed thought for every rattlesnake or other noxious creature whose life she had put out while doing her man’s work of riding the range,—work which had given her not only a man’s courage but a man’s skill as well.
 
“Take the back window, girl,” he answered, briefly. “I’ll take the front. Stand to the side. Get used to the starlight and shoot every shadow you see, especially if it moves. Keep track of your shots, don’t waste an effort and don’t let anything creep up on you. They mustn’t get near enough to fire the house.”
 
His voice was sharp and incisive. The drifting habit had fallen from him, and he was his own master again.
 
Several heavy minutes dragged away without movement, without sound from without. The ticking of the clock pressed on strained ears like ghastly bell-tolling. Their eyes became accustomed to the darkness and, by the dim starlight, they were able to distinguish the outlines of the cattle-sheds, still, empty, black. Nothing moved out there.
 
“I think they’re frightened off,” said Mary at last, breathing more freely. “They were probably just one, or they’d not have left. He knew he missed you, or he would not have fired again. Do you think it was Jesse?”
 
“Jesse would not have missed,” he said, grimly.
 
At that moment, a new sound broke the stillness, the whinny of a horse. Reinforcement had approached within the shadow of the cattle-sheds. Something moved out there at last.
 
“Daddy!” called Mary, in a choked whisper. “Come here—they are down at the sheds.”
 
Williston stepped to the back window quickly.
 
“Change places,” he said, briefly.
 
“Daddy!”
 
“Yes?”
 
“Keep up your nerve,” she breathed between great heart-pumps.
 
“Surely! Do you the same, little comrade, and shoot to kill.”
 
There was a savage note in his last words. For himself, it did not matter so much, but Mary—he pinned no false faith in any thought of possible chivalrous intent on the part of the raiders to exempt his daughter from the grim fate that awaited him. He had to deal with a desperate man; there would be no clemency in this desperate man’s retaliation.
 
To his quickened hearing came the sound of stealthy creeping. Something moved directly in front of him, but some distance away. “Shoot every shadow you see, especially if it moves,” were the fighting orders, and his was the third shot of that night.
 
“Hell! I’ve got it in the leg!” cried a rough voice full of intense anger and pain, and there were sounds of a precipitate retreat.
 
Out under protection of the long row of low-built sheds, other orders were being tersely given and silently received.
 
“Now, men, I’ll shoot the first man of you who blubbers when he’s hit. D’ye hear? There have been breaks enough in this affair already. I don’t intend for that petticoat man and his pulin’ petticoat kid in there to get any satisfaction out o’ this at all. Hear me?”
 
There was no response. None was needed.
 
Some shots found harmless lodgment in the outer walls of the shanty. They were the result of an unavailing attempt to pick the window whence Williston’s shot had come. Mary could not keep back a little womanish gasp of nervous dread.
 
“Grip your nerve, Mary,” said her father. “That’s nothing—shooting from down there. Just lie low and they can do nothing. Only watch, child, watch! They must not creep up on us. Oh, for a moon!”
 
She did grip her nerve, and her hand ceased its trembling. In the darkness, her eyes were big and solemn. Sometime, to-morrow, the reaction would come, but to-night—
 
“Yes, father, keep up your own nerve,” she said, in a brave little voice that made the man catch his breath in a sob.
 
Again the heavy minutes dragged away. At each of the two windows crouched a tense figure, brain alert, eyes in iron control. It was a frightful strain, this waiting game. Could one be sure nothing had escaped one’s vigilance? Starlight was deceptive, and one’s eyes must needs shift to keep the mastery over their little horizon. It might well be that some one of those ghostly and hidden sentinels patrolling the lonely homestead had wormed himself past staring eyeballs, crawling, crawling, crawling; it might well be that at any moment a sudden light flaring up from some corner would tell the tale of the end.
 
Now and then could be heard the soft thud of a hoof as some one rode to execute an order. Occasionally, something moved out by the sheds. Such movement, if discernible from the house, was sure to be followed on the instant by a quick sharp remonstrance from Williston’s rifle. How long could it last? Would his nerve wear away with the night? Could he keep his will dominant? If so, he must drag his mind resolutely away from that nerve-racking, still, and unseen creeping, creeping, creeping, nearer and nearer. How the stillness weighed upon him, and still his mind dwelt upon that sinuous, flat-bellied creeping, crawling, worming! God, it was awful! He fought it desperately. He knew he was lost if he could not stop thinking about it. The sweat came out in big beads on his forehead, on his body; he prickled with the heat of the effort. Then it left him—the awful horror—left him curiously cold, but steady of nerve and with a will of iron and eyes, cat’s eyes, for their seeing in the dark. Now that he was calm once more, he let himself weigh the chances of succor. They were pitifully remote. The Lazy S was situated in a lonely stretch of prairie land far from any direct trail. True, it lay between Kemah, the county seat, and the Three Bars ranch, but it was a good half mile from the straight route. Even so, it was a late hour for any one to be passing by. It was not a travelled trail except for the boys of the Three Bars, and they were known to be great home-stayers and little given to spreeing. As for the rustlers, if rustlers they were, they had no fear of interruption by the officers of the law, who held their places by virtue of the insolent and arbitrary will of Jesse Black and his brotherhood, and were now carousing in Kemah by virtue of the hush-money put up by this same Secret Tribunal.
 
Yet now that Williston’s head was clear, he realized, with strengthening confidence in the impregnability of their position, that two trusty rifles behind barred doors are not so bad a defence after all, especially when one took into consideration that, with the exception of the sheds overlooking which he had chosen his position as the point of greatest menace, and a small clump of half-grown cottonwoods by the spring which Mary commanded from her window, there were no hiding places to be utilize............
