Carthoris backed slowly away. He laid one hand upon his heart, the other upon the pommel of his long-sword.
"These are yours—always," he said. A moment later he had entered the palace, and was gone from the girl's sight.
Had he returned at once he would have found her prone upon the ersite bench, her face buried in her arms. Was she weeping? There was none to see.
Carthoris of Helium had come all unannounced to the court of his father's friend that day. He had come alone in a small flier, sure of the same welcome that always awaited him at Ptarth. As there had been no formality in his coming there was no need of formality in his going.
To Thuvan Dihn he explained that he had been but testing an invention of his own with which his flier was equipped—a clever improvement of the ordinary Martian air compass, which, when set for a certain destination, will remain constantly fixed thereon, making it only necessary to keep a vessel's prow always in the direction of the compass needle to reach any given point upon Barsoom by the shortest route.
