And he sprang forward to renew the combat. I stepped quietly, unflinchingly between him and Heliobas.
"Stop!" I exclaimed; "this cannot go on. Zara herself forbids it!"
The Prince paused, and looked at me in a sort of stupefaction.
"Zara forbids it!" he muttered. "What do you mean?"
"I mean," I went on, "that I have seen Zara since her death; I have spoken to her. She herself sent me here."
Prince Ivan stared, and then burst into a fit of wild laughter.
"Little fool!" he cried to me; "he has maddened you too, then! You are also a victim! Miserable girl! out of my path! Revenge--revenge! while I am yet sane!"
Then pushing me roughly aside, he cast away his sword, and shouted to Heliobas: "Hand to hand, villain! No more of these toy-weapons! Hand to hand!"
Heliobas instantly threw down his sword also, and rushing forward simultaneously, they closed together in savage conflict. Heliobas was the taller and more powerful of the two, but Prince Ivan seemed imbued with the spirit of a hundred devils, and sprang at his opponent's throat with the silent breathless ferocity of a tiger. At first Heliobas appeared to be simply on the defensive, and his agile, skilful movements were all used to parry and ward off the other's grappling eagerness. But as I watched the struggle, myself speechless and powerless, I saw his face change. Instead of its calm and almost indifferent expression, there came a look which was completely foreign to it--a look of savage determination bordering on positive cruelty. In a moment I saw what was taking place in his mind. The animal passions of the mere MAN were aroused--the spiritual force was utterly forgotten. The excitement of the contest was beginning to tell, and the desire of victory was dominant in the breast of him whose ideas were generally--and should have been now-- those of patient endurance and large generosity.
The fight grew closer, hotter, and more terrible. Suddenly the Prince swerved aside and fell, and within a second Heliobas held him down, pressing one knee firmly against his chest. From my point of observation I noted with alarm that little by little Ivan ceased his violent efforts to rise, and that he kept his eyes fixed on the overshadowing face of his foe with an unnatural and curious pertinacity. I stepped forward. Heliobas pressed his whole weight heavily down on the young man's prostrate body, while with both hands he held him by the shoulders, and gazed with terrific meaning into his fast-paling countenance. Ivan's lips turned blue; his eyes appeared to start from their sockets; his throat rattled. The spell that held me silent was broken; a flash of light, a flood of memory swept over my intelligence. I knew that Heliobas was exciting the whole battery of his inner electric force, and that thus employed for the purposes of vengeance, it must infallibly cause death. I found my speech at last.
