A glint of anger rose in the eyes of Barry.
"Joe Cumberland is sleepin' soun'," he answered. "He'll be a pile rested when he wakes up. He don't need me no more."
"He's not the only one who needs you," said Byrne. "His daughter has been waiting impatiently for your coming, sir."
The sharp glance of Barry wavered away.
"I'd kind of like to stay," he murmured, "but I got to go."
A dull voice called from the next room.
"It's Joe Cumberland," said Byrne. "You see, he is not sleeping!"
The brow of Barry clouded, and he turned gloomily back.
"Maybe I better stay," he agreed.
Yet before he made a step Byrne heard a far-away honking of the wild geese, that musical discord carrying for uncounted miles through the windy air. The sound worked like magic on Barry. He whirled back.
"I got to go," he repeated.
And yet Byrne blocked the way. It required more courage to do that than to do anything he had ever attempted in his life. The sweat poured out from under his armpits as the stranger stepped near; the blood rushed from his face as he stared into the eyes of Barry—eyes which now held an uncanny glimmer of yellow light.
"Sir," said Byrne huskily, "you must not go! Listen! Old Cumberland is calling to you again! Does that mean nothing? If you have some errand out in the night, let me go for you."
"Partner," said the soft voice of Barry, "stand aside. I got no time, I'm wanted!"
Every muscle of Randall Byrne's body was set to repulse the stranger in any effort to pass through that door, and yet, mysteriously, against his will, he found himself standing to one side, and saw the other slip through the open door.
"Dan! Are ye there?" called a louder voice from the room beyond.
There was no help for it. He, himself, must go back and face Joe Cumberland. With a lie, no doubt. He would say that Dan had stepped out for a moment and would be back again. That might put Cumberland safely to sleep. In the morning, to be sure, he would find out the deception—but let every day bury its dead. Here was enough trouble for one night. He went slowly, but steadily enough, towards the door of what had now become a fatal room to the doctor. In that room he had seen his dearest doctrines cremated. Out of that room he had come bearing the ashes of his hopes in his hands. Now he must go back once more to try to fill, with science, a gap of which science could never take cognizance.
He lingered another instant with his hand on the door; then he cast it wide bravely enough and stepped in. Joe Cumberland was sitting up on the edge of his couch. There was colour in the old man's face. It almost seemed, to the incredulous eyes of Byrne, that the face was filled out a trifle. Certainly the fire of the old cattleman's glance was less unearthly.
"Where's Dan?" he called. "Where'd he go?"
It was no longer the deep, controlled voice of the stoic; it was the almost whining complaint of vital weakness.
"Is there anything I can do for you?" parried Byrne. "Anything you need or wish?"
"Him!" answered the old man explosively. "Damn it, I need Dan! Where is he? He was here. I felt him here while I was sleepin'. Where is he?"
"He has stepped out for an instant," answered Byrne smoothly. "He will be back shortly."
"He—has—stepped—out?" echoed the old man slowly. Then he rose to the full of his gaunt height. His white hair, his triangle of beard and pointed moustache gave him a detached, a mediaeval significance; a portrait by Van Dyck had stepped from its frame.
"Doc, you're lyin' to me! Where has he gone?"
A sudden, almost hysterical burst of emotion swept Doctor Byrne.
"Gone to heaven or hell!" he cried with startling violence. "Gone to follow the wind and the wild geese—God knows where!"
Like a period to his sentence, a gun barked outside, there was a howl of demoniac pain and rage, and then a scream that would tingle in the ear of Doctor Randall Byrne till his dying day.
XXIII. HOW MAC STRANN KEPT THE LAW
For when the dog sprang, Mac Strann fired, and the wolf was jerked up in the midst of his leap by the tearing impact of the bullet. It was easy for Strann to dodge the beast, and the great black body hurtled past him and struck heavily on the floor of the barn. It missed Mac Strann, indeed, but it fell at the very feet of Haw-Haw Langley, and a splash of blood flirted across his face. He was too terrified to shriek, but fell back against the wall of the barn, gasping. There he saw Black Bart struggle to regain his feet, vainly, for both of the animal's forelegs seemed paralyzed. Now the yellow light of the fire rose brightly, and by it Haw-Haw marked the terrible eyes and the lolling, slavering tongue of the great beast, and the fangs like ivory daggers. It could not regain its feet, but it thrust itself forward by convulsive efforts of the hind legs towards Mac Strann.
Haw-Haw Langley stared for a single instant in white-faced fear, but when he realised that Black Bart was helpless as a toothless old dog, the tall cowpuncher twisted his lean fingers with a silent joy. Once more Bart pushed himself towards Mac Strann, and then Haw-Haw Langley stepped forward, and with all the force of his long leg smashed his heavy riding boot into the face of the dog. Black Bart toppled back against the base of the manger, struggled vainly to regain his poise, and it was then that he pointed his nose up, and wailed like a lost soul, wailed with the fury of impotent hate. Mac Strann caught Haw-Haw by the arm and dragged him back towards the door.
"I don't want to kill the dog," he repeated. "Get out of here, Haw-Haw. Barry'll be comin' any minute."
He could have used no sharper spur to urge on the laggard. Haw-Haw Langley raced out of the barn a full stride before Mac Strann. They hurried together to the little rise of ground behind which they had left their horses, and as they ran the scream which had curdled the blood of Randall Byrne rang through the night. In a thousand years he could never have guessed from what that yell issued; his nearest surmise would have been a score of men screaming in unison under the torture. But Mac Strann and Haw-Haw Langley knew the sound well enough.
When they mounted their saddles they could look over the top of the little hill and observe everything easily without being seen, for the hill-top commanded a range of the corrals and a view of the fronts of the barns and sheds which opened upon the fenced enclosures. The largest and longest of these buildings was now plainly visible, for a long arm of fire reached above the roof on one side of the low shed and by this growing light the other barns, the glimmering-eyed horses and cattle of the corrals, the trees about the house, the house itself, were in turn visible, though vaguely, and at times, as the flame lapsed, all were lost in a flood of swift darkness. Once more that unhuman shriek echoed from hill to hill and from building to building. It was Satan in his box stall. The flames were eating through the partition, and the stallion was mad with fear.
Lights flashed, here and there, in the big ranch house; and from the bunk-house on the farther side of the corrals rose a volley of curses and yells of dismay. The cattle began milling
