the eyes of Thuvia of Ptarth—only horror for the thing the man had done and for its possible consequences. “Release me.” Her voice was level—frigid. The man muttered incoherently and drew her roughly toward him. “Release me!” she repeated sharply, “or I call the guard, and the Prince of Dusar knows what that will mean.” Quickly he threw his right arm about her shoulders and strove to draw her face to his lips. With a little cry she struck him full in the mouth with the massive bracelets that circled her free arm. “Calot!” she exclaimed, and then: “The guard! The guard! Hasten in protection of the Princess of Ptarth!” In answer to her call a dozen guardsmen came racing across the scarlet sward, their gleaming long-swords naked in the sun, the metal of their accoutrements clanking against that of their leathern harness, and in their throats hoarse shouts of rage at the sight which met their eyes. But before they had passed half across the royal garden to where Astok of Dusar still held the struggling girl in his grasp, another figure sprang from a cluster of dense foliage that half hid a golden fountain close at hand.

Astok still clutched Thuvia’s wrist as the young warrior confronted him.

Her champion turned toward the girl. “Kaor, Thuvia of Ptarth!” he cried. “It seems that fate timed my visit well.” “Kaor, Carthoris of Helium!”
