But it made no effort to fight these bonds. It just crouched there in the strange semi-gloom, watching with pale-gleaming eyes the movements of its self-proclaimed Master. Subconsciously Rocky Russell had been expecting just some such revelation as this. Even so, it was one case where realization of an idea far surpassed speculation. A gasp of sheer astonishment wrenched itself from his lips; he stared at the giant with shocked incredulity. "Colossus!" he choked. "Lord--the Colossus himself, come to life! Grossman, where did you find this--?" Grossman smiled urbanely. "Not a bad name for him, Captain. Your brief period of masquerade as a mythologist apparently left some impression on you. Colossus--yes! But this time no brainless monster of brass. A living creature, intelligent and obedient to my commands. You, there!" He turned and addressed his slave, again utilizing the menavisal unit. "You know your orders? You know what must be done?" * * * * * The creature had telepathic power commensurate with its bulk. The mental answer came rolling into the brains of the Earthmen with almost audible force. "_I know my orders. I know what must be done._" "And who is Master? Whose will must be obeyed?" This, thought Rocky with swift distaste, was sheer braggadocio, and typical of Grossman. It was not necessary to bludgeon a servile answer out of the gigantic captive. He had already proven his point. But if the question had been intended to elicit a humble deference, it failed in its purpose. For the Colossus did not answer. Instead, it continued to stare down at its accoster mutely, speculatively. Almost, thought Rocky, defiantly. "Well?" repeated Grossman. "Who is Master here?" And this time, whipping a tube from his holster, he accompanied the question with a rapier-like lash of fire that swept across the Colossus' hurriedly upraised palm. For at sight of the gun, at the crackle of the heat-beam, the giant had begun to stammer a hasty answer-- "_You, O Master! You are Master! You--_" And then, as suddenly as it had begun--it stopped! And over its features spread a strange, strained look. What that expression meant, Rocky could not guess. It seemed to mirror surprise. Vast, pleased surprise. The giant lifted the palm across which Grossman's ray had swept and studied it with sluggish interest. It drew a finger of its other hand across what should be a badly burned piece of flesh ... and began smiling. It was an evil smile. There was no mirth in it. Just grim, savage exultation. And determination! Then deliberately it reached forward--and attempted to grasp Grossman! This time it was the Factor who fell back hurriedly. A cry burst from his lips, he pointed the Haemholtz at the giant and coldly, murderously, turned its ray to the maximum concentration. The air of the confined quarters seethed and crackled with blistering heat as the livid flame blasted its way to its target. But the Colossus ... _laughed_!
