And so, for all his fevered thinking, he got no radical, no practical solution of the terrible problem.  More and more definitely, as he weighed the pros and cons, the belief was borne in upon him that in this case he must appeal to nobody but himself, count on nobody, trust in nobody save Gabriel Armstrong.

“I must play a lone hand game, for a while at least,” he concluded, as he finished his casting and took another.  “Later, perhaps, I can enlist my comrades.  But for now, I must watch, wait, work, all alone.  Perhaps, armed with this knowledge—­invaluable knowledge shared by no one—­I can meet their moves, checkmate their plans and defeat their ends.  Perhaps!  It will be a battle between one man, obscure and without means, and two men who hold billions of dollars and unlimited resources in their grasp.  A battle unequal in every sense; a battle to the death.  But I may win, after all.  Every probability is that I shall lose, lose everything, even my life.  Yet still, there is a chance.  By God, I’ll take it!”

The last words, uttered aloud, seemed to spring from his lips as though uttered by the very power of invincible determination.  A sneer, behind him, brought him round with a start.  His gaze widened, at sight of Herzog standing there, cold and dangerous looking, with a venomous expression in those ill-mated eyes of his.

“Take it, will you?” jibed the scientist.  “You thief!”

Gabriel sprang up so suddenly that his stool clattered over backward on the red-tiled floor.  His big fist clenched and lifted.  But Herzog never flinched.

“Thief!” he repeated, with an ugly thrust of the jaw.  Servile and crawling to his masters, the man was ever arrogant and harsh with those beneath his authority.  “I repeat the word.  Drop that fist, Armstrong, if you know what’s good for you.  I warn you.  Any disturbance, here, and—­well, you know what we can do!”

The electrician paled, slightly.  But it was not through cowardice.  Rage, passion unspeakable, a sudden and animal hate of this lick-spittle and supine toady shook him to the heart’s core.  Yet he managed to control himself, not through any personal apprehension, but because of the great work he knew still lay before him.  At all hazards, come what might, he must stay on, there, at the Oakwood Heights plant.  Nothing, now, must come between him and that one supreme labor.

Thus he controlled himself, with an effort so tremendous that it wrenched his very soul.  This trouble, whatever it might be, must not be noised about.  Already, up and down the shop, workers were peering curiously at him.  He must be calm; must pass the insult, smooth the situation and remain employed there.

“I—­I beg pardon,” he managed to articulate, with pale lips that trembled.  He wiped the beaded sweat from his broad forehead.  “Excuse me, Mr. Herzog.  I—­you startled me.  What’s the trouble?  Any complaint to make?  If so, I’m here to listen.”
