“It is fortunate that you left me here, red man,” said the bowman. “I but just now intercepted one who seemed over-anxious to reach this door—it was he whom they call Astok, Prince of Dusar.”

Carthoris smiled.

“Where is he now?” he asked.

“He escaped my blade, and ran down this corridor,” replied Kar Komak.

“We must lose no time, then!” exclaimed Carthoris. “He will have the guard upon us yet!”

Together the three hastened along the winding passages through which Carthoris and Kar Komak had tracked the Dusarians by the marks of the latter’s sandals in the thin dust that overspread the floors of these seldom-used passage-ways.

They had come to the chamber at the entrances to the lifts before they met with opposition. Here they found a handful of guardsmen, and an officer, who, seeing that they were strangers, questioned their presence in the palace of Astok.

Once more Carthoris and Kar Komak had recourse to their blades, and before they had won their way to one of the lifts the noise of the conflict must have aroused the entire palace, for they heard men shouting, and as they passed the many levels on their quick passage to the landing stage they saw armed men running hither and thither in search of the cause of the commotion.

Beside the stage lay the Thuria, with three warriors on guard. Again the Heliumite and the Lotharian fought shoulder to shoulder, but the battle was soon over, for the Prince of Helium alone would have been a match for any three that Dusar could produce.

Scarce had the Thuria risen from the ways ere a hundred or more fighting men leaped to view upon the landing stage. At their head was Astok of Dusar, and as he saw the two he had thought so safely in his power slipping from his grasp, he danced with rage and chagrin, shaking his fists and hurling abuse and vile insults at them.
