"Everything is going wrong," I said to Ptor Fak a moment later, after I saw a warrior enter one of the streets, hoping that it was he who had spoken to us and that there were no others around.

"It seems hopeless, doesn't it?" said Ptor Fak.

"No," I snapped, "not while I still live."

The following afternoon Kandus's voice came and sat down beside me. "How goes it?" he asked.

"Terrible," I said.

"How is that?" he asked.

"I can't tell you," I said, "because there is probably a guard standing right here listening to everything that I say."

"There is no one here but us," said Kandus.

"How do you know?" I asked; "your people are as invisible to you as they are to me."

"We learn to sense the presence of others," he explained; "just how, I can't tell you."

"How you do it is immaterial," I said, "as long as you are sure there is no one here listening to us. I will be perfectly frank with you, I succeeded in removing Ptor Fak's shackle and my own. Someone caught me at it and took the piece of wire away from me." I did not tell Kandus that I had broken the wire he had given me in two and that I still had the other half of it in my pocket pouch. There is no use in telling even a friend everything that you know.

"How in the world could you have hoped to escape even if you could remove your shackles?" he asked.

"It was only the first step," I told him. "We really had no plan, but we knew that we certainly could not escape as long as we were shackled."

Kandus laughed. "There is something in that," he said, and then he was silent for a moment. "The girl who was captured with you," he said presently.

"What of her?" I asked.

"Ptanus has given her to Motus," he replies; "it was all done very suddenly. Why, no one seems to know, because Ptantus hasn't any particular love for Motus."

If Kandus didn't know why, I thought that I did. I saw Rojas's hand and a green-eyed devil in it-jealousy is a heartless monster. "Will you do something more for me, Kandus?" I asked.

"Gladly, if I can," he replied.

"It may seem like a very silly request," I said, "but please don't ask me to explain. I want you to go to Rojas and tell her that Llana of Gathol, the girl that Ptantus has given to Motus, is the daughter of my daughter." It may seem strange to you denizens of Earth that Rojas could have become infatuated with a grandfather, but you must remember that Mars is not Earth and that I am unlike all other Earth men. I do not know how old I am. I recall no childhood. It seems to me that have just always been, and I have always been the same. I look now as I did when I fought with the Confederate army during the Civil War-a man of about thirty. And here on Barsoom, where the natural span of life is around a thousand years and people do not commence to show the ravages of old age until just shortly before dissolution, differences in age do not count. You might fall in love with a beautiful girl on Barsoom; and, as far as appearances were concerned, she might be seventeen or she might be seven hundred.

"Of course I don't understand," said Kandus, "but I'll do what you ask."

"And now another favor," I said. "Ptantus half promised me that he would let me duel with Motus and he assured me that Motus would kill me. Is there any possible way of arranging for that duel to be fought today?"

"He will kill you," said Kandus.

"That is not what I asked," I said.

"I don't know how it could be done," said Kandus.

"Now if Ptantus has any sporting blood," I suggested, "and likes to lay a wager now and then, you bet him that if Motus will fight me while Motus is still visible, that he cannot kill me but that I can kill him whenever I choose."

"But you can't do it," said Kandus. "Motus is the best swordsman on Barsoom. You would be killed and I should lose my money."

"How can I convince you?" I said. "I know that I can kill Motus in a fight. If I had anything of value, I would give it to you as security for your wager."

"I have something of value," said Ptor Fak, "and I would wager it and everything that I could scrape together on Dotar Sojat." He reached into his pocket pouch and drew froth a gorgeous jewelled medallion. "This," he said to Kandus, "is worth a jeddak's ransom-take it as security and place its value on Dotar Sojat."

A second later the medallion disappeared in thin air, and we knew that Kandus had reached out his hand and taken it.

"I'll have to go inside and examine it," said Kandus' voice, "for of course I cannot see it now that it has become invisible. I'll not be gone long."

"That is very decent of you, Ptor Fak," I said, "that medallion must be almost invaluable."

"One of my remote ancestors was a jeddak," explained Ptor Fak; "that medallion belonged to him, and it has been in the family for thousands of years."

"You must be quite certain of my swordsmanship," I said.

"I am," he replied; "but even had I been less certain, I should have done the same."

"That is friendship," I said, "and I appreciate it."

"It is priceless," said a voice at my side, and I knew that Kandus had returned.

"I will go at once and see what can be done about the duel."

"Don't forget what I asked you to tell Rojas," I reminded him.

After Kandus left us, time dragged heavily. The afternoon wore on and it became so late that I was positive that he had failed in his mission. I was sitting dejectedly thinking of the fate that was so soon to overtake Llana of Gathol. I knew that she would destroy herself, and I was helpless to avert the tragedy.

And, while I was thus sunk in the depths of despair, a hand was placed on mine.

A soft hand; and a voice said, "Why didn't you tell me?"

"You didn't give me a chance," I said; "you just ran out on me without giving me a chance to explain."

"I am sorry," said the voice, "and I am sorry for the harm I have done Llana of Gathol; and now I have condemned you to death."

"What do you mean?" I asked.

"Ptantus has commanded Motus to fight you and kill you."

I threw my arms around Rojas and kissed her. I couldn't help it, I was so happy.

"Good!" I exclaimed. "Though neither of us realized it at the time, you have done me a great favor."

"What do you mean?" she demanded.

"You have given me the chance to meet Motus in a fair fight; and now I know that Llana of Gathol will be safe-as far as Motus is concerned."

"Motus will kill you," insisted Rojas.

"Will you be there to see the duel?" I asked.

"I do not wish to see you killed," she said, and clung to me tightly.

"You haven't a thing to worry about, I shall not be killed; and Motus will never have Llana of Gathol or any other woman."

"You can tell his friends to start digging his grave immediately," said Ptor Fak.

"You are that sure?" said Rojas.

"We have the princess," said Ptor Fak, which is the same as saying in America "It is in the bag." The expression derives from the Barsoomian chess game, Jetan, in which the taking of a princess decides the winner and ends the game.

"I hope you are right," said Rojas. "At least you have encouraged me to believe, and it is not so difficult to believe anything of Dotar Sojat."

"Do you know when I am to fight Motus?" I asked.

"This evening," replied Rojas, "before the whole Court in the throne room of the palace."

"And after I have killed him?" I asked.

"That is to be feared, too," said Rojas, "for Ptantus will be furious. He will not only have lost a fighting man but all the money he has wagered on the duel."

"But it will soon be time," she added, "and I must go now." I saw her open my pocket pouch and drop something into it, and then she was gone.

I knew from the surreptitious manner in which she had done it that she did not wish anyone to know what she had put in my pocket pouch, or in fact that she had put anything into it; and so I did not investigate immediately, fearing that someone may have been watching and had their suspicions aroused. The constant strain of feeling that unseen eyes may be upon you, and that unseen ears may be listening to your every word was commencing to tell upon me; and I was becoming as nervous as a cat with seven kittens.
