After a long silence Ptor Fak said, "What are you going to do with her?"

I knew what he meant; because the same question had been worrying me. "If we succeed in getting out of this," I said, "I am going to take her back to Helium with me and let Dejah Thoris convince her that there are a great many more charming men that I there." I had had other women fall in love with me and this would not be the first time that Dejah Thoris had unscrambled things for me. For she knew that no matter how many women loved me, she was the only woman whom I loved.

"You are a brave man," said Ptor Fak.

"You say that because you do not know Dejah Thoris," I replied; "it is not that I am a brave man, it is that she is a wise woman."

That started me off again thinking about her, although I must confess that she is seldom absent from my thoughts. I could picture her now in our marble palace in Helium, surrounded by the brilliant men and women who crowd her salons. I could feel her hand in mine as we trod the stately Barsoomian dances she loves so well. I could see her as though she were standing before me this minute, and I could see Thuvia of Ptarth, and Carthoris, and Tara of Helium, and Gahan of Gathol. That magnificent coterie of handsome men and beautiful women bound together by ties of love and marriage. What memories they evoked!

A soft hand caressed my cheek and a voice, tense with nervousness said, "Live! Live for me! I shall return at midnight and you must be here;" then she was gone.

For some reason or other which I cannot explain, her words quieted my nerves.

They gave me confidence that at midnight I should be free. Her presence reminded me that she had dropped something into my pocket pouch and I opened it casually and put my hand into it. My fingers came in contact with a number of spheres, about the size of marbles, and I knew that the secret of invisibility was mine.

I moved close to Ptor Fak; and once again with the remaining bit of wire I picked the lock of his shackle, and then I handed him one of the spheres that Rojas had given me.

I leaned very close to his ear. "Take this," I whispered; "in an hour you will be invisible. Go to the far end of the courtyard and wait. When I return I too shall be invisible and when I whistle thus, answer me." I whistled a few of the opening notes of the national anthem of Helium, a signal that Dejah Thoris and I had often used.

"I understand," said Ptor Fak.

"What do you understand?" demanded a voice.

Doggonit! there was that invisibility nemesis again and now all our plans might be knocked into a cocked hat. How much had the fellow heard? What had he seen? I trembled inwardly, fearing the answer. Then I felt hands at my ankle and saw my shackle fall open.

"Well," repeated the voice peremptorily, "what was it that you understood?"

"I was just telling Ptor Fak," I said, "how I was going to kill Motus, and he said he understood perfectly."

"So you think you are going to kill Motus, do you?" demanded the voice. "Well, you are going to be very much surprised for a few minutes, and after that you will be dead. Come along with me; the duel is about to take place."

I breathed a sigh of relief. The fellow had evidently seen or heard nothing of any importance.

"I'll see you later, Ptor Fak," I said.

"Good-by and good luck," he replied. And then, accompanied by the warrior, I entered a city street on my way to the throne room of Ptantus, jeddak of Invak.

"So you think you're pretty good with the sword," said the warrior walking at my side and who was now visible to me.

"Yes," I replied.

"Well, you're going to get a lesson in swordsmanship tonight. Of course it won't do you much good because after it is all over you will be dead."

"You are very encouraging," I said, "but if you are fond of Motus, I suggest that you save your encouragement for him. He is going to need it."

"I am not fond of Motus," said the warrior; "no one is fond of Motus. He is a calot and I apologize to calots for the comparison. I hope that you kill him but of course you won't. He always kills his man, but he is tricky. Watch out for that."

"You mean he doesn't fight fair?" I asked.

"No one ever taught him the word," said the warrior.

"Well, thank you for warning me," I said; "I hope you stay to see the fight, maybe you will be surprised."

"I shall certainly stay to see it," he said. "I wouldn't miss it for the world. But I am not going to be surprised; I know just what will happen. He will play with you for about five minutes and then he'll run you through; and that won't please Ptantus for he likes a long drawn out duel."

"Oh, he does does he?" I said. "Well, he shall have it." That fitted in perfectly with my plans. I had swallowed one of the invisibility spheres just before the warrior unshackled me, and I knew that it would take about an hour for it to effect perfect invisibility. It might be difficult to drag the duel out for an hour, but I hoped to gain a little time by stalling up to the moment that we crossed swords. And I accomplished it now by walking slowly to kill as much time as possible, and twice I stopped to tighten the fastenings of my sandals.

"What's the matter?" demanded the warrior. "Why do you walk so slow? Are you afraid?"

"Terrified," I replied. "Everyone has told me how easily Motus is going to kill me. Do you think that a man wants to run to his death?"

"Well, I don't blame you much," said the warrior, "and I won't hurry you."

"A lot of you Invaks are pretty good fellows," I remarked.

"Of course we are," he said. "What made you think anything different?"

"Pnoxus, Motus, and Ptantus," I replied.

The warrior grinned. "I guess you are a pretty shrewd fellow," he said, "to have sized them up this quickly."

"Everybody seems to hate them," I said; "why don't you get rid of them? I'll start you off by getting rid of Motus tonight."

"You may be a good swordsman," said the warrior, "but you are bragging too much; I never knew a braggart yet who could 'take the princess.'"

"I am not bragging," I said; "I only state facts." As a matter of fact, I often realize that in speaking of my swordsmanship, it may sound to others as though I were bragging but really I do not feel that I am bragging. I know that I am the greatest swordsman of two worlds. It would be foolish for me to simper, and suck my finger, and say that I was not. I am, and everyone who has seen me fight knows that I am. Is it braggadocio to state a simple fact? It has saved a number of lives, for it has kept no end of brash young men from challenging me.

Fighting has been, you might say, my life's work. There is not a lethal weapon in the use of which I do not excel, but the sword is my favorite. I love a good blade and I love a good fight and I hoped that tonight I should have them both.

I hoped that Motus was all that they thought him. The thought might have obtruded on the consciousness of some men that perhaps he was, but no such idea ever entered my head. They say that overconfidence often leads to defeat, but I do not think that I am ever overconfident. I am merely wholly confident, and I maintain that there is all the difference in the world there.

At last we came to the throne room. It was not the same room in which I had first seen Ptantus; it was a much larger room, a more ornate room; and at one side of it was a raised dais on which were two thrones. They were empty now, for the jeddak and the jeddara had not yet appeared. The floor of the room was crowded with nobles and their women. Along three sides of the room were several tiers of benches, temporary affairs, which had evidently been brought in for the occasion. They were covered with gay cloths and cushions; but they were still empty, for, of course, no one could sit until the jeddak came and was seated.
