I snarled wordlessly. He sighed.
"As always the barbarian. Truly the proverb speaks: 'Jest with the wounded tiger and warm the adder in your bosom before you seek to lift the savage from his savagery.'"
He meditated awhile in silence. I watched him uneasily. There was about him a vague and curious difference—his long fingers emerging from the sleeves drummed on the chair arms and some hidden exultation strummed at the back of his voice, lending it unaccustomed vibrancy.
"And you might have been a king of the new regime," he said suddenly. "Aye, the new—new and inhumanly old!"
I shuddered as his dry cackling laugh rasped out.
He bent his head as if listening. From far off seemed to come a hum of guttural voices. His lips writhed in a smile.
"My black children," he murmured. "They tear my enemy Gordon to pieces in the tunnels. They, Mr. Costigan, are my real henchmen and it was for their edification tonight that I laid John Gordon on the sacrificial stone. I would have preferred to have made some experiments with him, based on certain scientific theories, but my children must be humored. Later under my tutelage they will outgrow their childish superstitions and throw aside their foolish customs, but now they must be led gently by the hand.
"How do you like these under-the-earth corridors, Mr. Costigan?" he switched suddenly. "You thought of them—what? No doubt that the white savages of your Middle Ages built them? Faugh! These tunnels are older than your world! They were brought into being by mighty kings, too many eons ago for your mind to grasp, when an imperial city towered where now this crude village of London stands. All trace of that metropolis has crumbled to dust and vanished, but these corridors were built by more than human skill—ha ha! Of all the teeming thousands who move daily above them, none knows of their existence save my servants—and not all of them. Zuleika, for instance, does not know of them, for of late I have begun to doubt her loyalty and shall doubtless soon make of her an example."
At that I hurled myself blindly against the side of the cage, a red wave of hate and fury tossing me in its grip. I seized the bars and strained until the veins stood out on my forehead and the muscles bulged and crackled in my arms and shoulders. And the bars bent before my onslaught—a little but no more, and finally the power flowed from my limbs and I sank down trembling and weakened. Kathulos watched me imperturbably.
"The bars hold," he announced with something almost like relief in his tone. "Frankly, I prefer to be on the opposite side of them. You are a human ape if there was ever one."
