Here, there, everywhere, he searched, at last finding a back room to the building, that was separated from the main hall. He pressed against the door. The lock sagged--but did not open. Carefully he brought forth his skeleton keys, and tried them, one after another. At last, a rusty creaking of the lock, a slight snap, and the door opened. Grant hesitated a moment, listening for some sign that he had been overheard from within. But none came. Then he entered. Within the back room, he stopped again to listen. From the other side of the door that separated him from the main room of the meeting hall, he could hear the thick, heavy voice of Heinric von Lertz, apparently giving the last of a long series of orders: "Imperial Germany expects every man of you to do his duty and to see that Union Labor is driven from Old Forge," he was saying. "We have here enough dynamite to blow up every miner's house and every coal mine in the district--and I want to see every bit of it used. As soon as we receive the word that everything is all right we will proceed----" "Here I am sir!" At the sound of the voice, Grant opened the door ever so slightly, to see the form of the spy he had trailed, hurrying up the aisle. "The constabulary is all at the coal dumps, and they have their hands full. If we work quickly----" "All right. Line up, everybody. You will pass the platform, one at a time and receive your dynamite. Then, each man will cause one explosion--and the result will be that the whole city will be wrecked! Hurry there, line up, line up!" Grant hurried back to the door for one look up the street. If Dixie were only on the way with the constabulary. If he could only catch sight of her, leading the plunging mass of horsemen on their way to the hall! But Harrison Grant looked in vain. There was no sight of the girl he loved, no sight of the hurrying horsemen that would mean safety for the town of Old Forge. Grant's heart sank within him. Beyond him in the hall were more than two hundred desperate men and hundreds of pounds of explosives. And they must not be permitted to start forth on their journey of destruction! Grant hesitated only a second. Then as the line of destroyers within the main meeting hall started to receive their dynamite---- A hurtling form crashed through the door from the back room. Leaping toward Stanley Dembriki, in charge of the dynamite, he felled him with a crashing blow from his fist. Heinric von Lertz took one look and ran through the door that had been left open by the entrance of Harrison Grant. But the I.W.W. members could only see this one form and could only know that Grant had interfered with their schemes of destruction. A second of hesitation, then they rushed forward. But Grant was ready for them. A heavy chair stood nearby. He seized it and taking his place near the dynamite, felled the first man who approached. The crackle of a revolver sounded, and a bullet splintered the wood just above his head. Then a shout----
