"There he is, Mr. Lidgerwood," snarled the engineer-constable. "I nabbed him over yonder at the fire, workin' to put it out, just as if he hadn't told his gang to go and set it!"

"Hallock!" exclaimed the superintendent, starting as if he had seen a ghost. "How is this? Are there two of you?"

Hallock looked down moodily. "There were two of us who wanted your job, and the other one needed it badly enough to wreck trains and to kill people, and to lead a lot of pig-headed trainmen and mechanics into a riot to cover his tracks."

Lidgerwood turned quickly. "Unmask those men, McCloskey."

It was the signal for a tumult. The tall man fought desperately to preserve his disguise, but Flemister's mask was torn off in the first rush. Then came a diversion, sudden and fiercely tragic. With a cry of rage that was like the yell of a madman, Hallock flung himself upon the mine-owner, beating him down with his manacled hands, choking him, grinding him into the dust of the floor. And when the avenger of wrongs was pulled off and dragged to his feet, Lidgerwood, looking past the death grapple, saw the figure of a woman swaying at the corridor door; saw the awful horror in her eyes. In the turning of a leaf he had fought his way to her.

"Good heavens, Eleanor!" he gasped. "What are you doing here?" and he faced her about quickly and led her into the corridor lest she should see the distorted features of the victim of Hallock's vengeance.

"I came—they took the car away, and I—I was left behind," she faltered. And then: "Oh, Howard! take me away; hide me somewhere! It's too horrible!"

There was a bull-bellow of rage from the room they had just left, and Lidgerwood hurried his companion into the first refuge that offered, which chanced to be the trainmaster's room. Out of the private office and into the corridor came the taller of the two garroters, holding his mask in place as he ran, with McCloskey, Judson, and all but one or two of the others in hot pursuit.

Notwithstanding, the fugitive gained the stair and fell, rather than ran, to the bottom. There was the crash of a bursting door, a soldierly command of "Halt!" the crack of a cavalry rifle, and McCloskey came back, wiping his homely face with a bandanna.

"They got him," he said; and then, seeing Eleanor for the first time, his jaw dropped and he tried to apologize. "Excuse me, Miss Brewster; I didn't have the least idea you were up here."
