"Halt! Halt there! Halt, or I'll fire!" cried Gage. "Halt!" He called it out again, once, twice, three times. But the figure, whoever or whatever it was, ran on. It now had reached the top of the dam, and could be seen with more or less distinctness, sky-lined against the starlight and the gray sky behind it.
Sim Gage, old-time hunter, used all his life to firearms, was used also to firing at running game. He drew down now deep into the rear sight of his Springfield, allowing for the faint light, and held at the front edge of the running figure as nearly as he could tell. He fired once, twice and three times—rap!—rap!—rap!—the echo came from the concrete—at the figure as it crouched and stumbled on. Then it stopped. There came a scrambling and a sliding of the object, which fell at the top of the dam. It slipped off the dam top and rolled and slid almost at his feet. He dragged it down into the edge of the beams of the searchlight itself.
Up to this time he had not known or suspected who the man might be. At first he now thought it was a woman. In reality it was a Chinaman, the cook and body-servant of Waldhorn, engineer at the power operations! He was dead.
Sim stood looking down at what he had done, trying in his slow fashion of mind to puzzle out what this man had been doing here, and why he had come. He heard the sound of running feet above him, heard challenges, shouts, every way. Others had heard the shot. "This way, fellers—— Come along!" he heard Wid Gardner call out, high and clear; for that night Wid also was of the upper guard.
But they were not running in his direction. They seemed to be back on the street. All at once Sim Gage solved his little problem. This Chinaman had been sent to do this work—sent by the owner of that house yonder, the engineer, Waldhorn. That prisoner must not escape now. He knew! It was he who had given the searchlight signal! Waldhorn—and Dorenwald! He coupled both names now again.
Sim Gage himself, having a shorter distance to go than his comrades, left his dead Chinaman, and started after the man higher up. He reached the Waldhorn quarters slightly before the others.
He heard the screen door of the log house slam, saw a stout and burly man step out, satchel in hand. The man walked hurriedly toward a car which Sim Gage had not noticed, since there was so much unused machinery about, wheel scrapers, wagons, plows and the like. Now he saw that it was Waldhorn and Waldhorn's car. He was taking advantage of this confusion to make his own escape.
This hurrying figure halted for a half instant in the dim light, for he heard footsteps on each side of him. He knew the guard was coming.
Sim Gage's summons rang high and clear. Yonder was the man—he was going to escape. He must not escape. All these things came to Sim Gage's mind as he half raised his weapon to his shoulder, challenging again, "Halt! Who goes there? Halt!" The bolt of his Springfield clinked home once more.
The man turned away, toward the sound of the greater number of his enemies, weapon in hand. The patrol was closing in. But before he turned he both gave and received death in the last act he might offer in treachery to this country, which had been generous and kind to him.
