"You are tiring, Motus," I said to him; "hadn't you better finish me off now before you become wholly exhausted?"

"I'll finish you off all right, slave," he came back, "if you'll stand still and fight."

"It is not time to kill you yet, Motus," I said, glancing up at the clock, "when the hand points to eleven xats past the 8th zode, I shall kill you."

"Silence," screeched the referee.

"What is the slave saying?" demanded Ptantus in stentorian tones.

"I said," I shouted back at him, "that I should kill Motus at exactly 8 zodes, 11 xats. Watch the clock, Ptantus, for at that instant you are going to lose your wager, and Motus his life."

"Silence," commanded the jeddak.

"Now, Motus," I whispered, "I am going to show you how easily I can kill you when the time comes," and with that I disarmed him and, sent his sword clattering across the floor.

A mighty gasp arose from the audience, for now under the rules of a duel of this nature, I was at liberty to run Motus through the heart; but instead I rested my point upon the floor and turned to the referee.

"Go and fetch Motus's sword," I said, "and return it to him."

Motus was trembling a little. I could see his knees shake though almost imperceptibly. I knew then what I had suspected before-Motus was yellow.

While the referee was retrieving Motus's sword, a little ripple of applause ran through the stands. But Ptantus only sat and scowled more fiercely; I fear that Ptantus did not like me.

When Motus's sword was returned to him, he came for me furiously; and I knew perfectly well what was in his mind; he was going to finish me off immediately.

I disarmed him again; and again I lowered my point, while the referee without waiting to be told ran after the blade.

Now Motus was more wary. I could see that he was trying to work me around to some position in which he wished to have me. I noticed presently that the referee was not within my range of vision, and a quick glance told me he was standing directly behind me; it was not intuition that told me why, for I had seen that trick played before by crooked swordsmen with an accomplice. I heard a few groans from the stands; and then I knew that I was right, for no honorable person could witness such a thing without voicing his disapproval.

When Motus next lunged, hoping to force me back, the referee would «accidentally» be close behind me; I would bump into him, and Motus would have me at his mercy. It is a despicable trick; and Ptantus must have seen it coming, but he made no move to prevent it.

I watched Motus's eyes and they telegraphed his intention to me an instant before he lunged, throwing all his weight behind it. I had slightly crouched in anticipation of this and my Earthly muscles carried me to one side, and Motus's sword drove to the hilt through the body of the referee.

For a moment pandemonium reigned in the throne room. The entire audience stood up in the stands and there were cheers and groans, and something told me that the cheers were for me and the groans for Motus and the referee.

Motus was a terribly unstrung and rattled man as he jerked his blade from the body of the dead man, but now I gave him no respite. I went after him in earnest, though not yet for the kill. I cut a deep gash across his swollen jaw.

"You will not make a good-looking corpse now, Motus," I said, "and before I am through with you, you are going to look a great deal worse."

"Calot!" he snapped, and then he rushed me, cutting and thrusting violently. I parried every cut and thrust and wove a net of steel around him, and every time he missed I brought blood from some new spot on his body.

"You have three xats to live, Motus," I said; "you had better make the best of them."

He rushed at me like a madman; but I sidestepped him and as he turned I took off one of his ears as neatly as a surgeon could have done it-I thought he was going to faint, for his knees seemed to give beneath him and he staggered about for a moment.

I waited for him to recover control of himself, and then I went to work on him again. I tried to carve my initials on his breast, but by this time there was not a whole place large enough; from the waist up he looked like a plate of raw hamburger.

The floor was covered with his blood by now; and as he rushed me again furiously, he slipped and fell. He lay there for a moment glaring at me, for I am sure he expected that I would finish him off then; but instead I said, "You have a xat and a half to live yet, Motus."

He staggered to his feet and tried to throw himself upon me, screaming imprecations as he came. I think that by this time Motus had gone quite mad from pain and terror. I felt no sympathy for him-he was a rat; and now he was fighting like a cornered rat.

"The floor is too slippery here," I said to him; "lets go over by the jeddak's throne-I am sure that he would like to see the finish."

I maneuvered him around into position and backed him across the floor until we stood directly in front of Ptantus.

It is seldom that I have ever punished a man as I punished Motus; but I felt that he deserved it, and I was the plaintiff, prosecuting attorney, jury, and judge; I was also the executioner.

Motus was gibbering now and making futile passes at me with his blade. Ptantus was glaring at me, and the audience was tense with breathless expectancy. I saw many an eye glance quickly at the clock.

"One more tal, Motus," I said. A tal is about eight tenths of an Earthly second.

At that Motus turned suddenly and ran screaming toward the great doorway that led from the throne room; and again the audience rose to its feet, and there were groans and cries of "Coward!"

The fight was to have been to the death and Ptantus had wagered that I would not kill Motus. If I did not kill him, I feared that Ptantus would then claim the money; so I risked everything on an art I had often practiced for my own amusement. I carried my sword hand far behind my right shoulder and then brought it forward with all my strength, releasing the blade point first. It flew like a sped arrow and drove through Motus's body below the left shoulder blade at exactly 11 xats past the 8th zode.

I turned and bowed to Ptantus, now having no sword with which to salute him. He should have acknowledged this customary courtesy but he did nothing of the sort, he merely glared at me and stood up. The jeddara arose too; and, with the trumpeters before them and the courtiers behind, the two stalked out of the throne room, making a wide detour to avoid the blood and the two corpses.

After they had left, the warrior who had brought me from the courtyard came and touched me on the arm. "Come," he said. "All you get out of this is to be chained to your tree again."

"I got a great deal more than that out of it," I replied, as I accompanied him across the throne room; "I had the satisfaction of avenging a cowardly kick."

As we crossed towards the doorway, someone started cheering and then practically the entire audience took it up. "That is an unusual demonstration," said the warrior, "but you deserve it. No one on Barsoom ever saw such swordplay as you showed us tonight-and I thought you were boasting!" He laughed.

I knew that it would be necessary for us to cross a couple of courtyards before we reached the one in which I had been confined; and I realized that if I suddenly disappeared before the warrior's eyes, he would know that I had obtained invisibility spheres; and while of course he couldn't have found me, it would certainly have started an investigation and would have upset our plans for escape. If they knew that I was at large and invisible, one of the first things that they would most naturally have done would have been to place a guard over my flier.
