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.
