As Wayne Colt moved restlessly upon his hard couch, Firg, a lesser priest of Opar, snored upon his pallet of straw in the small, dark recess that was his bed chamber. Firg was the keeper of the keys, and so impressed was he with the importance of his duties that he never would permit anyone even to touch the sacred emblems of his trust, and probably because it was well known that Firg would die in defense of them they were entrusted to him. Not with justice could Firg have laid any claim to intellectuality, if he had known that such a thing existed. He was only an abysmal brute of a man and, like many men, far beneath the so-called brutes in many of the activities of mind. When he slept, all his faculties were asleep, which is not true of wild beasts when they sleep.

Firg's cell was in one of the upper stories of the ruins that still remained intact. It was upon a corridor that encircled the main temple court—a corridor that was now in dense shadow, since the moon, touching it early in the night, had now passed on; so that the figure creeping stealthily toward the entrance to Firg's chamber would have been noticeable only to one who happened to be quite close. It moved silently, but without hesitation, until it came to the entrance beyond which Firg lay. There it paused, listening, and when it heard Firg's noisy snoring, it entered quickly. Straight to the side of the sleeping man it moved, and there it knelt, searching with one hand lightly over his body, while the other grasped a long, sharp knife that hovered constantly above the hairy chest of the priest.

Presently it found what it wanted—a great ring, upon which were strung several enormous keys. A leather thong fastened the ring to Firg's girdle, and with the keen blade of the dagger the nocturnal visitor sought to sever the thong. Firg stirred, and instantly the creature at his side froze to immobility. Then the priest moved restlessly and commenced to snore again, and once more the dagger sawed at the leather thong. It passed through the strand unexpectedly and touched the metal of the ring lightly, but just enough to make the keys jangle ever so slightly.

Instantly Firg was awake, but he did not rise. He was never to rise again.

Silently, swiftly, before the stupid creature could realize his danger, the keen blade of the dagger had pierced his heart.

Soundlessly, Firg collapsed. His slayer hesitated a moment with poised dagger as though to make certain that the work had been well done. Then, wiping the tell-tale stains from the dagger's blade with the victim's loin cloth, the figure arose and hurried from the chamber, in one hand the great keys upon their golden ring.

Colt stirred uneasily in his sleep and then awakened with a start. In the waning moonlight he saw a figure beyond the grating of his cell. He heard a key turn in the massive lock. Could it be that they were coming for him? He rose to his feet, the urge of his last conscious thought strong upon him—escape. And then as the door swung open, a soft voice spoke, and he knew that the girl had returned.

She entered the cell and threw her arms about Colt's neck, drawing his lips down to hers. For a moment she clung to him, and then she released him and, taking one of his hands in hers, urged him to follow her; nor was the American loath to leave the depressing interior of the death cell.

On silent feet Nao led the way across the corner of the sacrificial court, through a dark archway into a gloomy corridor. Winding and twisting, keeping always in dark shadows, she led him along a circuitous route through the ruins, until, after what seemed an eternity to Colt, the girl opened a low, strong, wooden door and led him into the great entrance hall of the temple, through the mighty portal of which he could see the inner wall of the city.

Here Nao halted, and coming close to the man looked up into his eyes. Again her arms stole about his neck, and again she pressed her lips to his. Her cheeks were wet with tears, and her voice broke with little sobs that she tried to stifle as she poured her love into the ears of the man who could not understand.
