It was the deep suspense of Cumberland which made him so silently alert. He was as intensely alive as the receiver of a wireless apparatus; he gathered information from the empty air.
So that Byrne was hardly surprised, when, in the midst of that grim silence, the old man raised a rigid forefinger of warning. Kate and Daniels stiffened in their chairs and Byrne felt his flesh creep. Of course it was nothing. The wind, which had shaken the house with several strong gusts before dinner, had now grown stronger and blew with steadily increasing violence; perhaps the sad old man had been attracted by the mournful chorus and imagined some sound he knew within it.
But now once more the finger was raised, the arm extended, shaking violently, and Joe Cumberland turned upon them a glance which flashed with a delirious and unhealthy joy.
"Listen!" he cried. "Again!"
"What?" asked Kate.
"I hear them, I tell you."
Her lips blanched, and parted to speak, but she checked the impulse and looked swiftly about the room with what seemed to Byrne an appeal for help. As for Buck Daniels, he changed from a dark bronze to an unhealthy yellow; fear, plain and grimly unmistakable, was in his face. Then he strode to the window and threw it open with a crash. The wind leaped in and tossed the flame in the throat of the chimney, so that great shadows waved suddenly through the room, and made the chairs seem afloat. Even the people were suddenly unreal. And the rush of the storm gave Byrne an eerie sensation of being blown through infinite space. For a moment there was only the sound of the gale and the flapping of a loose picture against the wall, and the rattling of a newspaper. Then he heard it.
First it was a single note which he could not place. It was music, and yet it was discordant, and it had the effect of a blast of icy wind.
Once he had been in Egypt and had stood in a corridor of Cheops' pyramid. The torch had been blown out in the hand of his guide. From somewhere in the black depths before them came a laugh, made unhuman by echoes. And Byrne had visioned the mummied dead pushing back the granite lids of their sarcophagi and sitting upright.
But that was nothing compared with this. Not half so wild or strange.
He listened again, breathless, with the sharp prickling running up and down his spine. It was the honking of the wild geese, flying north. And out of the sound he builded a picture of the grey triangle cleaving through the cold upper sky, sent on a mission no man could understand.
"Was I right? Was I right?" shrilled the invalid, and when Byrne turned towards him, he saw the old man sitting erect, with an expression of wild triumph. There came an indescribable cry from the girl, and a deep throated curse from Buck Daniels as he slammed down the window.
With the chill blast shut off and the flame burning steadily once more in the lamp, a great silence besieged the room, with a note of expectancy in it. Byrne was conscious of being warm, too warm. It was close in the room, and he was weighted down. It was as if another presence had stepped into the room and stood invisible. He felt it with unspeakable keenness, as when one knows certainly the thoughts which pass in the mind of another. And, more than that, he knew that the others in the room felt what he felt. In the waiting silence he saw that the old man lay on his couch with eyes of fire and gaping lips, as if he drank the wine of his joyous expectancy. And big Buck Daniels stood with his hand on the sash of the window, frozen there, his eyes bulging, his heart thundering in his throat. And Kate Cumberland sat with her eyes closed, as she had closed them when the wind first rushed upon her, and she still smiled as she had smiled then. And to Byrne, more terrible than the joy of Joseph Cumberland or the dread of Buck Daniels was the smile and the closed eyes of the girl.
But the silence held and the fifth presence was in the room, and not one of them dared speak.
CHAPTER VI
THE MISSION STARTS
Then, with a shifting of the wind, a song was blown to them from the bunk-house, a cheerful, ringing chorus; the sound was like daylight—it drove the terror from the room. Joe Cumberland asked them to leave him. That night, he said, he would sleep. He felt it, like a promise. The other three went out from the room.
In the hall Kate and Daniels stood close together under a faint light from the wall-lamp, and they talked as if they had forgotten the presence of Byrne.
"It had to come," she said. "I knew it would come to him sooner or later, but I didn't dream it would be as terrible as this. Buck, what are we going to do?"
"God knows," said the big cowpuncher. "Just wait, I s'pose, same as we've been doing."
He had aged wonderfully in that moment of darkness.
"He'll be happy now for a few days," went on the girl, "but afterwards—when he realises that it means nothing—what then, Buck?"
The man took her hands and began to pat them softly as a father might soothe a child.
"I seen you when the wind come in," he said gently. "Are you going to stand it, Kate? Is it going to be hell for you, too, every time you hear 'em?"
She answered: "If it were only I! Yes, I could stand it. Lately I've begun to think that I can stand anything. But when I see Dad it breaks my heart—and you—oh, Buck, it hurts, it hurts!" She drew his hands impulsively against her breast. "If it were only something we could fight outright!"
Buck Daniels sighed.
"Fight?" he echoed hopelessly. "Fight? Against him? Kate, you're all tired out. Go to bed, honey, and try to stop thinkin'—and—God help us all!"
She turned away from him and passed the doctor—blindly.
Buck Daniels had set his foot on the stairs when Byrne hurried after him and touched his arm; they went up together.
"Mr. Daniels," said the doctor, "it is necessary that I speak with you, alone. Will you come into my room for a few moments?"
"Doc," said the cattleman, "I'm short on my feed and I don't feel a pile like talkin'. Can't you wait till the morning?"
"There has been a great deal too much waiting, Mr. Daniels," said the doctor. "What I have to say to you must be said now. Will you come in?"
"I will," nodded Buck Daniels. "But cut it short."
Once in his room the doctor lighted the lamp and then locked the door.
"What's all the mystery and hush stuff?" growled Daniels, and with a gesture he refused the proffered chair. "Cut loose, doc, and make it short."
The little man sat down, removed his glasses, held them up to the light, found a speck upon them, polished it carefully away, replaced the spectacles upon his nose, and peered thoughtfully at Buck Daniels.
Buck Daniels rolled his eyes towards the door and then even towards the window, and then, as one who accepts the inevitable, he sank into a chair and plunged his hands into his pockets, prepared to endure.
"I am called," went on the doctor dryly, "to examine a case in which the patient is dangerously ill—in fact, hopelessly ill, and I have found that the cause of his illness is a state of nervous expectancy on the part of the sufferer. It being obviously necessary to know the nature of the disease and its cause before that cause may be removed, I have asked you to sit here this evening to give me whatever explanation you may have for it."
Buck Daniels stirred uneasily. At length he broke out: "Doc, I size you up as a gent with brains. I got one piece of advice for you: get the hell away from the Cumberland Ranch and never come back again!"
The doctor flushed and his lean jaw thrust out.
"Although," he said, "I cannot pretend to
