“Damn you, I think I'm the one to ask for an explanation,” he growled. “She said she was not going with you, and now you are around here together at this hour. I had a right to know whether I was being played with like that.”

“But, man, that was not Miss Maclaire I was with; it was Hope Waite. Come back here under the tent flap while I explain.”

Fearful of the coming of Hawley he fairly dragged the portly figure of the bewildered Doctor with him, striving, by quickly spoken words, to make him comprehend the situation. Knowing previously something of the issues involved, it was not difficult to make Fairbain grasp the meaning of this present movement, yet his sympathies were at once enlisted upon the side of Miss Christie. He'd be damned if he would have any part in such a scheme—if she had a right to the money he'd help her get it—it was a cowardly trick, and he'd fight if necessary, to keep her from becoming a victim. His voice rose, his arms brandishing violently, his sentences snapping like rifle shots. Keith angered, and fearful of a discovery which would leave Hope exposed, realized the futility of discussion and turned to physical force. Grasping the gesticulating man with both hands, he flung him backward and dragged him into the empty tent, kneeling on him as he throttled him to the earth.

“Now, Doctor, you listen to me,” he said sternly, “I'm through arguing. I hate to treat you like this, for you are my friend, but I'll not stand for interference here. Do you get that, you old fool? Lie still until I get through! I respect your feelings toward Miss Maclaire. She is a good girl, and I hope to heaven you get her if you want her. But you never will if you permit this affair to go on. Yes, I know what I am talking about. In all that Hope and I do we are serving you and Christie,—our only fight is with 'Black Bart' Hawley. Stop being a bullet-headed old fool, Fairbain, and understand this thing. Lie still, I tell you, and hear me out! Hawley is a liar, a thief, and a swindler. There is a swindle in this thing somewhere, and he hopes to pull out a big sum of money from it. He is merely using Christie to pull his own chestnuts out of the fire. She is innocent; we realize that, but this fellow is going to ruin the girl unless we succeed in exposing him. He's not only involving her in his criminal conspiracy, but he's making love to her; he's teaching her to love him. That's part of his scheme, no doubt, for then she will be so much easier handled. I tell you, Fairbain, your only chance to ever win the interest of Christie Maclaire is to help us down this fellow Hawley. Yes, you can sit up; I reckon you're beginning to see clearer, ain't you?”

Keith drew aside the flap of the tent to glance without, the light falling on Fairbain's face as he struggled to a sitting posture. He had had a new thought driven into him, yet failed to entirely grasp its significance.

“But, Jack,” he asked, still half angry, “how about the girl? Hasn't she any right to this money?”

“I don't know,” honestly, “we don't any of us know, but whatever she has the right to she is going to get. You can bet on that, old man. We're bucking Hawley not Christie Maclaire—get that into your head. He hasn't any right, that's certain, for he murdered and stole to get the papers—be quiet! Here the fellow comes now!”

They peered out together through the convenient tent flap, Fairbain scarcely less interested than the other, already dimly comprehending that his truly dangerous rival was the gambler, and that he could best serve the lady by helping to prove to her the real character of that individual. He was still blindly groping in the haze, yet out of Keith's sharp, stinging words there had come to him a guiding light. The latter gripped his arm in restraint.

“Easy, old man, easy—let him pass.”

Hawley turned into the alley whistling, evidently well pleased with the situation and anticipating other delights awaiting his coming. The glow of the Trocadero's lights served, an instant, to reveal his face, shaded by the broad brim of his hat, and then he vanished into the dark. Keith leaning far out, yet keeping well within the shadows, heard the faint creak of the vestibule door and the soft murmur of distant voices. Then he drew back suddenly, his hand again grasping Fairbain. Two figures—those of a man and woman—emerged into the dim light, and as quickly disappeared. Apparently her hand was upon his arm, and he was bending down so as to gain a glimpse of the face partially concealed by the folds of the mantilla. Only a word or two reached them, a little laugh, and the woman's voice:
