"And who might that be?"

"Vad Varo," I replied.

"Ah, Vad Varo! I have seen him often. I was to have taken service in his guard when I finished my training. He married Valla Dia, our princess. He is a great warrior. And who is your friend that is his friend?"

"John Carter, Prince of Helium, Warlord of Mars," I replied.

Then indeed did his eyes go wide. "John Carter, you know him? Who has not heard of him, the greatest swordsman of all Barsoom? But how could such as you be friend of John Carter?"

"It may seem strange to you," I admitted, "but the fact remains that John Carter is my best friend."

"But what do you know of John Carter?" demanded the red man in the adjoining cage. "I am from Helium; and there is no creature like you in the entire empire. I think you are a great liar. You lied to me, and you lied to Jal Had, and now you are lying to this young slave. What do you think you can gain by telling so many lies? Have you never heard that Martians pride themselves upon being truthful men?"

"I have not lied," I said.

"You do not even know what John Carter looks like," taunted the red man.

"He has black hair and grey eyes, and a lighter skin than yours," I replied; "and he came from Jasoom, and he is married to Dejah Thoris, Princess of Helium. When he came to Barsoom, he was captured by the green men of Thark. He has fought in Okar, the land of the yellow men in the far north; and he has fought therns in the Valley Dor; the length and breadth of Barsoom, he has fought; and when I saw him last, we were in Morbus together."

The red man looked surprised. "By my first ancestor," he exclaimed, "but you do know a lot about John Carter. Perhaps you are telling the truth after all."

The young slave had looked at me with rapt attention. I could see that he was much impressed; and I hoped that I had won his confidence and that later I might win his friendship, for I wanted a friend in the palace of Jal Had, Prince of Amhor.

"So you have seen John Carter," he said. "You have talked with him, you have touched him. Ah, how wonderful!"

"Some day he may come to Amhor," I said, "and if he does, tell him that you knew Tor-dur-bar, and that you were kind to him; and John Carter will be your friend, too."

"I shall be as kind to you as I can," he said, "and if there is anything that I can do for you, I shall be glad to do it."

"There is something that you can do for me," I said.

"What is it?" he asked.

"Come closer, so that I may whisper it to you." He hesitated. "Do not be afraid; I shall not harm you."

Then he came close to the cage. "What is it?" he asked.

I kneeled and bent my lips close to his car. "I wish to know all that you can learn about the girl, Janai; I mean, what is happening to her in the palace of Jal Had, and what is going to happen to her."

"I shall tell you all that I can learn," he said; and then he took his empty hamper and went away.

Monotonous days came and went, relieved only by conversation with the red man in the adjoining cage, and by visits twice a day from the young slave from Duhor, whose name was Orm-O.

Quite a friendship developed between the red man from Helium and me. His name was Ur Raj; and when he told me it, I recalled having met him several years before.

He was from Hastor, a city on the frontier of the empire, and had been a padwar aboard one of the warships stationed there. I asked him if he remembered an officer named Vor Daj, and he said he remembered him very well.

"Do you know him?" he inquired.

"Intimately," I replied. "In fact, there is nobody in the world whom I know so well."

"But how do you know him?" he demanded.

"He was at Morbus with John Carter," I replied.

"He was a splendid officer," he said. "I recall having a long conversation with him when the grand fleet came to Hastor."

"You and he discussed an invention that you were working upon that would detect and locate enemy ships at a great distance, identifying them by the sound of their motors. You had discovered that no two motors gave forth the same vibrations, and you had developed an instrument that recorded these vibrations accurately at great distances. You also introduced him to a very beautiful young lady whom you hoped to take as your mate."

Ur Raj's eyes went wide in astonishment. "But how in the world could you know of these matters?" he demanded. "You must have been very intimate with him indeed if he narrated to you the gist of conversations that took place years before with a comparative stranger."

"He told neither me nor any other about your invention," I replied, "because he promised you that he would not say anything about it until you had fully developed it and offered it to the navy of Helium."

"But then if he did not tell you, how could you know these things?" he demanded.

"That, you may never know," I replied; "but you may rest assured that Vor Daj never abused your confidence."

I believe that Ur Raj was a little in awe of me after that, believing that I had some supernatural or occult powers. I used to catch him gazing at me intently as he squatted upon the floor of his cage, doubtless trying to fathom what seemed an inexplicable mystery to him.

The slave boy, Orm-O, became quite friendly, telling me all that he could learn about Janai, which was little or nothing. I gathered from him that she was in no immediate danger, as Jal Had's oldest wife had taken her under her protection.

Jal Had had several wives; and this first wife he feared above all things on earth. She had long objected to sharing the affections of Jal Had with other women; and she did not intend that the number should be increased, especially by the acquisition of so beautiful a young woman as Janai.

"It is rumored," said Orm-O, "that she will put Janai out of the way at the first opportunity. She is hesitating now only because of the fear that Jal Had, in his rage, would destroy her if she did so; but she may find a way to accomplish it without bringing suspicion upon herself. In fact, she has several times recently received Gantun Gur, the Assassin of Amhor, who recently returned from captivity. I can tell you that I should not like to be Janai, especially if Gantun Gur listens too long to Vanuma and accepts a commission from her."

This information caused me considerable concern for the welfare of Janai. Of course, I felt quite certain that Gantun Gur would not kill her; but that would not keep Vanuma from finding some other means, if she had determined to destroy Janai. I asked Orm-O to warn Janai, and he said that he would if he ever had an opportunity.

The danger threatening Janai was constantly on my mind, and my inability to aid her drove me almost to distraction. If there were only something that I might do. But there was nothing. I seemed to be utterly helpless, and Janai's situation equally hopeless.

Sometimes we had dull days at the zoo; but as a rule there was a steady stream of people passing along the avenue between the cages, and almost always there was a little crowd gathered in front of my cage when the avenue was not jammed by those who came and stood looking at me for hours at a stretch. There were always new faces; but there were those that I had learned to recognize because they came so often; and then one day I saw Gantun Gur in the crowd. He shouldered his way toward me, eliciting much grumbling and some hard words; but when someone recognized him and his name was passed around, the spectators gave way before him, for no one wished to antagonize the Assassin of Amhor. What a reputation the original must have gained!

"Kaor, Tor-dur-bar," he said, coming close to the cage.

"Kaor, Gantun Gur," I replied. "It is good to see you again; and I wish that I might speak to you privately."
