Thuvia shrank back. She thought the man mad. Her hand stole to the jewelled hilt of her dagger. The man saw the move, and stopped. A cunning expression entered his eyes. Then they became at once dreamy and penetrating as they fairly bored into the girl's brain.

Thuvia suddenly felt a change coming over her. What the cause of it she did not guess; but somehow the man before her began to assume a new relationship within her heart.

No longer was he a strange and mysterious enemy, but an old and trusted friend. Her hand slipped from the dagger's hilt. Tario came closer. He spoke gentle, friendly words, and she answered him in a voice that seemed hers and yet another's.

He was beside her now. His hand was up her shoulder. His eyes were down-bent toward hers. She looked up into his face. His gaze seemed to bore straight through her to some hidden spring of sentiment within her.

Her lips parted in sudden awe and wonder at the strange revealment of her inner self that was being laid bare before her consciousness. She had known Tario for ever. He was more than friend to her. She moved a little closer to him. In one swift flood of light she knew the truth. She loved Tario, Jeddak of Lothar! She had always loved him.

The man, seeing the success of his strategy, could not restrain a faint smile of satisfaction. Whether there was something in the expression of his face, or whether from Carthoris of Helium in a far chamber of the palace came a more powerful suggestion, who may say? But something there was that suddenly dispelled the strange, hypnotic influence of the man.

As though a mask had been torn from her eyes, Thuvia suddenly saw Tario as she had formerly seen him, and, accustomed as she was to the strange manifestations of highly developed mentality which are common upon Barsoom, she quickly guessed enough of the truth to know that she was in grave danger.

Quickly she took a step backward, tearing herself from his grasp. But the momentary contact had aroused within Tario all the long-buried passions of his loveless existence.

With a muffled cry he sprang upon her, throwing his arms about her and attempting to drag her lips to his.

«Woman!» he cried. «Lovely woman! Tario would make you queen of Lothar. Listen to me! Listen to the love of the last jeddaks of Barsoom.»

Thuvia struggled to free herself from his embrace.

«Stop, creature!» she cried. «Stop! I do not love you. Stop, or I shall scream for help!»

Tario laughed in her face.

«'Scream for help,'» he mimicked. «And who within the halls of Lothar is there who might come in answer to your call? Who would dare enter the presence of Tario, unsummoned?»

«There is one,» she replied, «who would come, and, coming, dare to cut you down upon your own throne, if he thought that you had offered affront to Thuvia of Ptarth!»

«Who, Jav?» asked Tario.

«Not Jav, nor any other soft-skinned Lotharian,» she replied; «but a real man, a real warrior-Carthoris of Helium!»

Again the man laughed at her.

«You forget the bowmen,» he reminded her. «What could your red warrior accomplish against my fearless legions?»

Again he caught her roughly to him, dragging her towards his couch.

«If you will not be my queen,» he said, «you shall be my slave.»

«Neither!» cried the girl.

As she spoke the single word there was a quick move of her right hand; Tario, releasing her, staggered back, both hands pressed to his side. At the same instant the room filled with bowmen, and then the jeddak of Lothar sank senseless to the marble floor.

At the instant that he lost consciousness the bowmen were about to release their arrows into Thuvia's heart. Involuntarily she gave a single cry for help, though she knew that not even Carthoris of Helium could save her now.

Then she closed her eyes and waited for the end. No slender shafts pierced her tender side. She raised her lids to see what stayed the hand of her executioners.

The room was empty save for herself and the still form of the jeddak of Lothar lying at her feet, a little pool of crimson staining the white marble of the floor beside him. Tario was unconscious.

Thuvia was amazed. Where were the bowmen? Why had they not loosed their shafts? What could it all mean?

An instant before the room had been mysteriously filled with armed men, evidently called to protect their jeddak; yet now, with the evidence of her deed plain before them, they had vanished as mysteriously as they had come, leaving her alone with the body of their ruler, into whose side she had slipped her long, keen blade.

The girl glanced apprehensively about, first for signs of the return of the bowmen, and then for some means of escape.

The wall behind the dais was pierced by two small doorways, hidden by heavy hangings. Thuvia was running quickly towards one of these when she heard the clank of a warrior's metal at the end of the apartment behind her.

Ah, if she had but an instant more of time she could have reached that screening arras and, perchance, have found some avenue of escape behind it; but now it was too late-she had been discovered!

With a feeling that was akin to apathy she turned to meet her fate, and there, before her, running swiftly across the broad chamber to her side, was Carthoris, his naked long-sword gleaming in his hand.

For days she had doubted his intentions of the Heliumite. She had thought him a party to her abduction. Since Fate had thrown them together she had scarce favoured him with more than the most perfunctory replies to his remarks, unless at such times as the weird and uncanny happenings at Lothar had surprised her out of her reserve.

She knew that Carthoris of Helium would fight for her; but whether to save her for himself or another, she was in doubt.

He knew that she was promised to Kulan Tith, Jeddak of Kaol, but if he had been instrumental in her abduction, his motives could not be prompted by loyalty to his friend, or regard for her honour.

And yet, as she saw him coming across the marble floor of the audience chamber of Tario of Lothar, his fine eyes filled with apprehension for her safety, his splendid figure personifying all that is finest in the fighting men of martial Mars, she could not believe that any faintest trace of perfidy lurked beneath so glorious an exterior.

Never, she thought, in all her life had the sight of any man been so welcome to her. It was with difficulty that she refrained from rushing forward to meet him.

She knew that he loved her; but, in time, she recalled that she was promised to Kulan Tith. Not even might she trust herself to show too great gratitude to the Heliumite, lest he misunderstand.

Carthoris was by her side now. His quick glance had taken in the scene within the room-the still figure of the jeddak sprawled upon the floor-the girl hastening toward a shrouded exit.

«Did he harm you, Thuvia?» he asked.

She held up her crimsoned blade that he might see it.

«No,» she said, «he did not harm me.»

A grim smile lighted Carthoris' face.

«Praised be our first ancestor!» he murmured. «And now let us see if we may not make good our escape from this accursed city before the Lotharians discover that their jeddak is no more.»

With the firm authority that sat so well upon him in whose veins flowed the blood of John Carter of Virginia and Dejah Thoris of Helium, he grasped her hand and, turning back across the hall, strode toward the great doorway through which Jav had brought them into the presence of the jeddak earlier in the day.

They had almost reached the threshold when a figure sprang into the apartment through another entrance. It was Jav. He, too, took in the scene within at a glance.

Carthoris turned to face him, his sword ready in his hand, and his great body shielding the slender figure of the girl.
