In the darkness he could not see whether there were the imprints of other sandals than Tara's-only that the dust was disturbed-and when it led him into gloomy corridors he lost the trail altogether. A perfect labyrinth of passages and apartments were now revealed to him as he hurried on through the deserted quarters of O-Mai. Here was an ancient bath-doubtless that of the jeddak himself, and again he passed through a room in which a meal had been laid upon a table five thousand years before-the untasted breakfast of O-Mai, perhaps. There passed before his eyes in the brief moments that he traversed the chambers, a wealth of ornaments and jewels and precious metals that surprised even the Jed of Gathol whose harness was of diamonds and platinum and whose riches were the envy of a world. But at last his search of O-Mai's chambers ended in a small closet in the floor of which was the opening to a spiral runway leading straight down into Stygian darkness. The dust at the entrance of the closet had been freshly disturbed, and as this was the only possible indication that Gahan had of the direction taken by the abductor of Tara it seemed as well to follow on as to search elsewhere. So, without hesitation, he descended into the utter darkness below. Feeling with a foot before taking a forward step his descent was necessarily slow, but Gahan was a Barsoomian and so knew the pitfalls that might await the unwary in such dark, forbidden portions of a jeddak's palace.
