But at that, I flatly refused, standing on my royal dignity; and I made them yield the point, maugre their stubborn insistence.
A tunnel stretched away into the dim distance, and up that tunnel we started—toward what? Steadily the blue light became stronger, and in my mind arose the certitude that it emanated from the Blue Image. Demon faces peered at us from cracks and crevices, but none of the devils of the place found hardihood to attack us.
The tunnel debouched into a great cavern. In the exact center, on a mound of bleached skulls stood the source of the blue radiance—the Sapphire Witch herself. I gasped in awed admiration at the flawless perfection of her beauty—and suddenly, how I did hate that sorcerer Agnor Halit, to whom I'd promised to deliver that exquisite Image of Incomparable Loveliness! Cheerfully would I have bartered the empires of the universe for its possession—did I but own those empires—nor would I have considered the price exorbitant. I wanted it—I wanted it! And I'd pledged
Around that mound, in a ring on the floor of the cavern, lay many stones. Half the size of human heads they were, round as balls, and no two were of the same color. Every one was aglow, softly, with inward lights, as if each were afire deep inside—dark reds there were; dull orange; dusky blues, garish greens and sinister purples. We knew they were sentient, malignant, resenting our intrusion! Koto responded by kicking one stone that was apparently sneering at him and radiating contempt. At the impact of Koto's foot, the smoldering stone gave forth a metallic clang like a smitten gong, rose straight in the air to the level of Koto's face—then hurtled straight at him with a speed that would have cracked his skull, had not Zarf struck at the Flying Stone with his sword and deflected its course.
A dozen of them promptly left the floor and flew at Zarf—who as promptly turned and fled. But he was actuated by discretion rather than fear. I saw him race headlong into a crack in the tunnel wall—and shortly, the devil who dwelt therein came tumbling out, well-nigh sheared in two by Zarf's sword. Evidently Zarf preferred coping with devils, to the Flying Stones. Koto, having the same idea, hastily retreated to the tunnel mouth—and I went with Koto. In another moment Zarf rejoined us there, grinning sheepishly. The Flying Stones did not follow us that far from the Blue Statue. . . .
We stood disconsolate, wondering how we were to pass their formidable menace—and as if to show us how futile was our quest, of a sudden the entire ring of Flying Stones levitated to the height of a man's shoulders and head, and commenced to swirl about the Sapphire Witch who stood so serene on her altar of skulls. Truly a strange goddess, and guarded by even stranger acolytes!
Fast and faster swirled the Flying Stones, their colored lights glowing more and more brightly—faster yet, until we could no longer distinguish any single stone—they were merely a beautiful, gleaming blur of fire—gradually a humming sound became audible, swelling in volume till it be-
