In the meantime, while this unmasking was taking place Frank had not been idle. He had longed to meet Black Harry face to face, but now he realized that his situation was perilous in the extreme. He must act at once. But the sight of the captive girl and her appeal for aid had bestirred all the chivalry of his nature. He longed to do something to save her. Swiftly moving near her, he suddenly caught her up, swung her over his shoulder, and, with her held thus, regardless of the shriek of terror that broke from her lips, he dashed straight for the open door of the hut. Cries of amazement broke from the lips of the outlaws. "There he goes!" shouted Black Harry. "That is the fellow who looks like me, and he has the girl! After him!" The men leaped in pursuit. Into the hut bounded Frank, and the door went to with a slam. The foremost man, who flung himself against it, found it had been fastened. "Well, we have him fast," said Black Harry, easily. "He can't get away in a thousand years. We'll dig him out at our convenience." The men now gathered round their boy chief, eager to hear his explanation. It was difficult for them to realize that they had been deceived--that the boy they rescued from the lynchers at Elreno jail was not their leader. "I was not fool enough to go into Elreno without disguising myself," said Harry. "I knew I should be recognized if I did. I fixed myself up in the outfit I just threw off, and, with this English tourist rig and a sissy lisp, I succeeded in deceiving everybody. "You may imagine how surprised I was when I saw this other fellow, who is nearly my perfect double. He took the train at Oklahoma City, and I sat directly behind him. I was there when the private detective, Burchel Jones, who fancies he is so shrewd, arrested him. "If they had lynched him, I could have disappeared, and it would have been thought that Black Harry had gone up the flume. But you fellows thought that I was in the scrape, and you came round in time to save him. "I watched my opportunity to scoop the girl, and I have brought her here, although I was hotly pursued for a time, and I did not know but I'd have to drop her and get away alone. I succeeded in fooling the pursuers, and I arrived here at last. "My double and the girl for whom I have risked so much are in that hut. I propose to break down the door and go in." A wild shout came from the men. They were furious to think they had been so wonderfully deceived. "Down with the door!" "Drag him out!" "Shoot him!" With a hoarse roar of rage the Braves rushed toward the cabin, and flung themselves against the door, which went down with a crash, letting them into the hut. CHAPTER XII. A CHANCE IN A THOUSAND. Frank, with his usual daring and gallantry, had resolved to make an effort to save the unfortunate girl--to rescue her from the clutch of Black Harry.
