But the footfall which sounded in the apartment was a soft, padding step, with a little scratching sound, light as a finger running on a frosty window pane. And then a long, shaggy head slipped close to Whistling Dan. It was Black Bart!

A wave of terror swept through her. She remembered another scene, not many months before, when Black Bart had drawn his master away from her and led him south, south, after the wild geese. The wolf-dog had come again like a demoniac spirit to undo her plans!

Only an instant—the crisis of a battle—then the great beast turned slowly, faced her, slunk with his long stride closer, and then a cold nose touched the hand which gripped the arm of her chair. It gave her a welcome excuse for action of some sort; she reached out her hand, slowly, and touched the forehead of Black Bart. He winced back, and the long fangs flashed; her hand remained tremulously poised in air, and then the long head approached again, cautiously, and once more she touched it, and since it did not stir, she trailed the tips of her fingers backwards towards the ears. Black Bart snarled again, but it was a sound so subdued as to be almost like the purring of a great cat. He sank down, and the weight of his head came upon her feet. Victory!

In the full tide of conscious power she was able to drop her hand from her face, raise her head, turn her glance carelessly upon Dan Barry; she was met by ominously glowing eyes. Anger—at least it was not indifference.

He rose and stepped in his noiseless way behind her, but he reappeared instantly on the other side, and reached out his hand to where her fingers trailed limp from the arm of the chair. There he let them lie, white and cool, against the darkness of his palm. It was as if he sought in the hand for the secret of her power over the wolf-dog. She let her head rest against the back of the chair and watched the nervous and sinewy hand upon which her own rested. She had seen those hands fixed in the throat of Black Bart himself, once upon a time. A grim simile came to her; the tips of her fingers touched the paw of the panther. The steel-sharp claws were sheathed, but suppose once they were bared, and clutched. Or she stood touching a switch which might loose, by the slightest motion, a terrific voltage. What would happen?

Nothing! Presently the hand released her fingers, and Dan Barry stepped back and stood with folded arms, frowning at the fire. In the weakness which overcame her, in the grip of the wild excitement, she dared not stay near him longer. She rose and walked into the dining-room.

"Serve breakfast now, Wung," she commanded, and at once the gong was struck by the cook.

Before the long vibrations had died away the guests were gathered around the table, and the noisy marshal was the first to come. He slammed back a chair and sat down with a grunt of expectancy.

"Mornin', Dan," he said, whetting his knife across the table-cloth, "I hear you're ridin' this mornin'? Ain't going my way, are you?"

Dan Barry sat frowning steadily down at the table. It was a moment before he answered.
