He paused to let the full weight of this announcement impress his hearers, and that his statement was scarcely credited was evidenced by the impatient exclamation of incredulity which escaped the lips of Than Kosis.

"What manner of weird tale are you bringing me, Notan?" he cried.

"It is the truth, my Jeddak," replied the psychologist. "In fact the impressions were strongly marked on the brain of each of the four guardsmen. Their antagonist was a very tall man, wearing the metal of one of your own guardsmen, and his fighting ability was little short of marvelous for he fought fair against the entire four and vanquished them by his surpassing skill and superhuman strength and endurance. Though he wore the metal of Zodanga, my Jeddak, such a man was never seen before in this or any other country upon Barsoom.

"The mind of the Princess of Helium whom I have examined and questioned was a blank to me, she has perfect control, and I could not read one iota of it. She said that she witnessed a portion of the encounter, and that when she looked there was but one man engaged with the guardsmen; a man whom she did not recognize as ever having seen."

"Where is my erstwhile savior?" spoke another of the party, and I recognized the voice of the cousin of Than Kosis, whom I had rescued from the green warriors. "By the metal of my first ancestor," he went on, "but the description fits him to perfection, especially as to his fighting ability."

"Where is this man?" cried Than Kosis. "Have him brought to me at once. What know you of him, cousin? It seemed strange to me now that I think upon it that there should have been such a fighting man in Zodanga, of whose name, even, we were ignorant before today. And his name too, John Carter, who ever heard of such a name upon Barsoom!"

Word was soon brought that I was nowhere to be found, either in the palace or at my former quarters in the barracks of the air-scout squadron. Kantos Kan, they had found and questioned, but he knew nothing of my whereabouts, and as to my past, he had told them he knew as little, since he had but recently met me during our captivity among the Warhoons.

"Keep your eyes on this other one," commanded Than Kosis. "He also is a stranger and likely as not they both hail from Helium, and where one is we shall sooner or later find the other. Quadruple the air patrol, and let every man who leaves the city by air or ground be subjected to the closest scrutiny."

Another messenger now entered with word that I was still within the palace walls.

"The likeness of every person who has entered or left the palace grounds today has been carefully examined," concluded the fellow, "and not one approaches the likeness of this new padwar of the guards, other than that which was recorded of him at the time he entered."

"Then we will have him shortly," commented Than Kosis contentedly, "and in the meanwhile we will repair to the apartments of the Princess of Helium and question her in regard to the affair. She may know more than she cared to divulge to you, Notan. Come."

They left the hall, and, as darkness had fallen without, I slipped lightly from my hiding place and hastened to the balcony. Few were in sight, and choosing a moment when none seemed near I sprang quickly to the top of the glass wall and from there to the avenue beyond the palace grounds.

XXIII Lost in the Sky

Without effort at concealment I hastened to the vicinity of our quarters, where I felt sure I should find Kantos Kan. As I neared the building I became more careful, as I judged, and rightly, that the place would be guarded. Several men in civilian metal loitered near the front entrance and in the rear were others. My only means of reaching, unseen, the upper story where our apartments were situated was through an adjoining building, and after considerable maneuvering I managed to attain the roof of a shop several doors away.

Leaping from roof to roof, I soon reached an open window in the building where I hoped to find the Heliumite, and in another moment I stood in the room before him. He was alone and showed no surprise at my coming, saying he had expected me much earlier, as my tour of duty must have ended some time since.

I saw that he knew nothing of the events of the day at the palace, and when I had enlightened him he was all excitement. The news that Dejah Thoris had promised her hand to Sab Than filled him with dismay.

"It cannot be," he exclaimed. "It is impossible! Why no man in all Helium but would prefer death to the selling of our loved princess to the ruling house of Zodanga. She must have lost her mind to have assented to such an atrocious bargain. You, who do not know how we of Helium love the members of our ruling house, cannot appreciate the horror with which I contemplate such an unholy alliance."

"What can be done, John Carter?" he continued. "You are a resourceful man. Can you not think of some way to save Helium from this disgrace?"

"If I can come within sword's reach of Sab Than," I answered, "I can solve the difficulty in so far as Helium is concerned, but for personal reasons I would prefer that another struck the blow that frees Dejah Thoris."

Kantos Kan eyed me narrowly before he spoke.

"You love her!" he said. "Does she know it?"

"She knows it, Kantos Kan, and repulses me only because she is promised to Sab Than."

The splendid fellow sprang to his feet, and grasping me by the shoulder raised his sword on high, exclaiming:

"And had the choice been left to me I could not have chosen a more fitting mate for the first princess of Barsoom. Here is my hand upon your shoulder, John Carter, and my word that Sab Than shall go out at the point of my sword for the sake of my love for Helium, for Dejah Thoris, and for you. This very night I shall try to reach his quarters in the palace."

"How?" I asked. "You are strongly guarded and a quadruple force patrols the sky."

He bent his head in thought a moment, then raised it with an air of confidence.

"I only need to pass these guards and I can do it," he said at last. "I know a secret entrance to the palace through the pinnacle of the highest tower. I fell upon it by chance one day as I was passing above the palace on patrol duty. In this work it is required that we investigate any unusual occurrence we may witness, and a face peering from the pinnacle of the high tower of the palace was, to me, most unusual. I therefore drew near and discovered that the possessor of the peering face was none other than Sab Than. He was slightly put out at being detected and commanded me to keep the matter to myself, explaining that the passage from the tower led directly to his apartments, and was known only to him. If I can reach the roof of the barracks and get my machine I can be in Sab Than's quarters in five minutes; but how am I to escape from this building, guarded as you say it is?"

"How well are the machine sheds at the barracks guarded?" I asked.

"There is usually but one man on duty there at night upon the roof."

"Go to the roof of this building, Kantos Kan, and wait me there."

Without stopping to explain my plans I retraced my way to the street and hastened to the barracks. I did not dare to enter the building, filled as it was with members of the air-scout squadron, who, in common with all Zodanga, were on the lookout for me.

The building was an enormous one, rearing its lofty head fully a thousand feet into the air. But few buildings in Zodanga were higher than these barracks, though several topped it by a few hundred feet; the docks of the great battleships of the line standing some fifteen hundred feet from the ground, while the freight and passenger stations of the merchant squadrons rose nearly as high.

It was a long climb up the face of the building, and one fraught with much danger, but there was no other way, and so I essayed the task. The fact that Barsoomian architecture is extremely ornate made the feat much simpler than I had anticipated, since I found ornamental ledges and projections which fairly formed a perfect ladder for me all the way to the eaves of the building. Here I met my first real obstacle. The eaves projected nearly twenty feet from the wall to which I clung, and though I encircled the great building I could find no opening through them.
