The day following the coming of Vas Kor to the palace of the Prince of Helium great excitement reigned throughout the twin cities, reaching its climax in the palace of Carthoris. Word had come of the abduction of Thuvia of Ptarth from her father's court, and with it the veiled hint that the Prince of Helium might be suspected of considerable knowledge of the act and the whereabouts of the princess.
In the council chamber of John Carter, Warlord of Mars, was Tardos Mors, Jeddak of Helium; Mors Kajak, his son, Jed of Lesser Helium; Carthoris, and a score of the great nobles of the empire.
"There must be no war between Ptarth and Helium, my son,"said John Carter. "That you are innocent of the charge that has been placed against you by insinuation, we well know;but Thuvan Dihn must know it well, too.
"There is but one who may convince him, and that one be you. You must hasten at once to the court of Ptarth, and by your presence there as well as by your words assure him that his suspicions are groundless.
Bear with you the authority of the Warlord of Barsoom, and of the Jeddak of Helium to offer every resource of the allied powers to assist Thuvan Dihn to recover his daughter and punish her abductors, whomsoever they may be.
"Go! I know that I do not need to urge upon you the necessity for haste."Carthoris left the council chamber, and hastened to his palace.
Here slaves were busy in a moment setting things to rights for the departure of their master. Several worked about the swift flier that would bear the Prince of Helium rapidly toward Ptarth.
At last all was done. But two armed slaves remained on guard. The setting sun hung low above the horizon.
In a moment darkness would envelop all.
One of the guardsmen, a giant of a fellow across whose right cheek there ran a thin scar from temple to mouth, approached his companion. His gaze was directed beyond and above his comrade. When he had come quite close he spoke.
"What strange craft is that?" he asked.
The other turned about quickly to gaze heavenward.
Scarce was his back turned toward the giant than the short-sword of the latter was plunged beneath his left shoulder blade, straight through his heart.
Voiceless, the soldier sank in his tracks--stone dead.
Quickly the murderer dragged the corpse into the black shadows within the hangar. Then he returned to the flier.
Drawing a cunningly wrought key from his pocket-pouch, he removed the cover of the right-hand dial of the controlling destination compass. For a moment he studied the construction of the mechanism beneath.
Then he returned the dial to its place, set the pointer, and removed it again to note the resultant change in the position of the parts affected by the act.
A smile crossed his lips. With a pair of cutters he snipped off the projection which extended through the dial from the external pointer--now the latter might be moved to any point upon the dial without affecting the mechanism below. In other words, the eastern hemisphere dial was useless.
Now he turned his attention to the western dial.
This he set upon a certain point. Afterward he removed the cover of this dial also, and with keen tool cut the steel finger from the under side of the pointer.
As quickly as possible he replaced the second dial cover, and resumed his place on guard. To all intents and purposes the compass was as efficient as before; but, as a matter of fact, the moving of the pointers upon the dials resulted now in no corresponding shift of the mechanism beneath--and the device was set, immovably, upon a destination of the slave's own choosing.
Presently came Carthoris, accompanied by but a handful of his gentlemen. He cast but a casual glance upon the single slave who stood guard. The fellow's thin, cruel lips, and the sword-cut that ran from temple to mouth aroused the suggestion of an unpleasant memory within him.
He wondered where Saran Tal had found the man-- then the matter faded from his thoughts, and in another moment the Prince of Helium was laughing and chatting with his companions, though below the surface his heart was cold with dread, for what contingencies confronted Thuvia of Ptarth he could not even guess.
First to his mind, naturally, had sprung the thought that Astok of Dusar had stolen the fair Ptarthian; but almost simultaneously with the report of the abduction had come news of the great fetes at Dusar in honour of the return of the jeddak's son to the court of his father.
It could not have been he, thought Carthoris, for on the very night that Thuvia was taken Astok had been in Dusar, and yet--He entered the flier, exchanging casual remarks with his companions as he unlocked the mechanism of the compass and set the pointer upon the capital city of Ptarth.
