Eyes speak the truth more often than the lips. The eyes of Rapas the Ulsio told me that he did not agree with me that the killing of one of Ur Jan's assassins was of no concern to either him or me, but his lips spoke otherwise.

"Of course," he said, "it is nothing to me; but Ur Jan is furious. He has offered an immense reward for the positive identification of the man who killed Uldak and Povak. Tonight he meets with his principal lieutenants to perfect the details of a plan which, they believe, will definitely and for all time end the activities of John Carter against the guild of assassins. They--"

He stopped suddenly, and his eyes registered a combination of suspicion and terror. It was as though for a moment his stupid mind had forgotten the suspicion that it had held that I might be John Carter and then, after exposing some of the secrets of his master, he had recalled the fact and was terrified.

"You seem to know a great deal about Ur Jan," I remarked, casually. "One would think that you are a full-fledged member of his guild."

For a moment he was confused. He cleared his throat several times as though about to speak, but evidently he could not think of anything to say, nor could his eyes hold steadily to mine. I enjoyed his discomfiture greatly.

"No," he disclaimed, presently; "it is nothing like that. These are merely things that I have heard upon the street. They are merely gossip. It is not strange that I should repeat them to a friend."

Friend! The idea was most amusing. I knew that Rapas was now a creature of Ur Jan's and that, with his fellows, he had been commissioned to kill me; and I had been commissioned by Fal Sivas to kill Rapas; yet here we were, dining and gossiping together. It was a most amusing situation.

As our meal drew to an end, two villainous-looking fellows entered and seated themselves at a table. No sign passed between them and Rapas, but I recognized them both and knew why they were there. I had seen them both at the meeting of the assassins, and I seldom forget a face. Their presence was a compliment to me and an admission that Ur Jan realized that it would take more than one swordsman to account for me.

I should have been glad to put my mark upon their breasts, but I knew that if I killed them, the suspicion that Ur Jan harbored that I might be John Carter would be definitely confirmed. The killing of Uldak and Povak and the marking of their breasts with the sign of the Warlord might have been a coincidence; but if two more men, sent to destroy me, met a similar fate, no doubt could remain even in a stupid mind but that all four had come to their end at the hands of John Carter himself.

The men had but scarcely seated themselves when I arose. "I must be getting along, Rapas," I said; "I have some important work to do tonight. I hope you will forgive me for running off like this, but perhaps I shall see you again tomorrow night."

He tried to detain me. "Don't hurry away," he exclaimed; "wait just a few moments. There are a number of things I should like to talk to you about."

"They will have to wait until tomorrow," I told him. "May you sleep well, Rapas," and with that I turned and left the building.

I went only a short distance along the avenue in the opposite direction to that which led toward the house of Fal Sivas. I concealed myself in the shadows of a doorway then and waited, nor had I long to wait before the two assassins emerged and hurried off in the direction in which they supposed I had gone. A moment or two later Rapas came out of the building. He hesitated momentarily and then he started walking slowly in the direction taken by the assassins.

When all three were out of sight, I came from my hiding-place and went at once to the building on the top of which my flier was stored.

The proprietor was puttering around one of the hangars when I came onto the roof. I could have wished him elsewhere, as I did not particularly care to have my comings and goings known.

"I don't see much of you," he said.

"No," I replied; "I have been very busy." I continued in the direction of the hangar where my ship was stored.

"Going to take your flier out tonight?" he asked.

"Yes."

"Watch out for the patrol boats," he said, "if you are on any business you wouldn't want the authorities to know about. They have been awfully busy the last couple of nights."

I didn't know whether he was just giving me a friendly tip, or if he were trying to get some information from me. There are many organizations, including the government, that employ secret agents. For aught I knew, the fellow might be a member of the assassins' guild.

"Well," I said, "I hope the police don't follow me tonight." He pricked up his ears. "I don't need any help; and, incidentally, she is extremely good-looking."

I winked at him and nudged him with my elbow as I passed, in a fashion that I thought his low mentality would grasp. And it did.

He laughed and slapped me on the back. "I guess you're worried more about her father than you are the police," he said.

"Say," he called after me, as I was climbing to the deck of my flier, "ain't she got a sister?"

As I slipped silently out over the city, I heard the hangar man laughing at his own witticism; and I knew that if he had had any suspicions I had lulled them.

It was quite dark, neither moon being in the heavens; but this very fact would make me all the more noticeable to patrol boats above me when I was passing over the more brilliantly lighted portions of the city, and so I quickly sought dark avenues and flew low among the dense shadows of the buildings.

It was a matter of only a few minutes before I reached my destination and dropped my flier gently to the roof of the building that housed the headquarters of the assassins' guild of Zodanga.

Rapas' statement that Ur Jan and his lieutenants were perfecting a plan aimed at my activities against them was the magnet that had lured me here this night.

I had decided that I would not again attempt to use the anteroom off their meeting-place, as not only was the way to it fraught with too much danger but even were I to safely reach the shadowed niche behind the cupboard, I still would be unable to hear anything of their proceedings through the closed door.

I had another plan, and this I put into immediate execution.

I brought my flier to rest at the edge of the roof directly above the room in which the assassins met; then I made a rope fast to one of the rings in her gunwale.

Lying on my belly, I looked over the edge of the roof to make sure of my position and found that I had gauged it to a nicety. Directly below me was the edge of a balcony before a lighted window. My rope hung slightly to one side of the window where it was not visible to those within the room.

Carefully I set the controls of my ship and then tied the end of a light cord to the starting lever. These matters attended to, I grasped the rope and slipped over the eaves of the roof, carrying the light cord in one hand.

I descended quietly, as I had left my weapons on my flier lest they clank against one another or scrape against the side of the building as I descended and thus attract attention to me.

Very cautiously I descended; and when I had come opposite the window, I found that I could reach out with one hand and grasp the rail of the balcony. I drew myself slowly to it and into a position where I could stand securely.

Shortly after I had dropped below the edge of the roof, I had heard voices; and now that I was close to the window, I was delighted to discover that it was open and that I could hear quite well nearly all that was going on within the room. I recognized Ur Jan's voice. He was speaking as I drew myself to the balcony.
