Chapter 16: Invisible Foes

Looking down in the direction that Zanda had indicated, I saw what appeared to be a large building on the bank of a river. The structure nestled in a clearing in the forest, and where the rising sun touched its towers they sent back scintillant rays of many-hued light.

One section of the building faced upon what appeared to be a walled court, and it was an object lying in this court which aroused our interest and excitement to a far greater extent than the building itself.

"What do you think it is, Zanda?" I asked, for it was she who had discovered it.

"I think that it is Gar Nal's ship," replied the girl.

"What makes you think that?" asked Jat Or.

"Because it is so much like this one," she replied. "Both Gar Nal and Fal Savas stole ideas from one another whenever they could, and I should be surprised indeed if their ships did not closely resemble one another."

"I am sure that you are right, Zanda," I said. "It is not reasonable to assume that the inhabitants of Thuria have, by some miraculous coincidence, constructed a ship so similar to that of Fal Sivas's; and the possibility is equally remote that a third Barsoomian ship has landed on the satellite."

I directed the brain to spiral downward, and presently we were flying at an altitude that gave us a clear view of the details of the building and the surrounding terrain.

The more closely we approached the ship in the courtyard the more certain we became that it was Gar Nal's; but nowhere did we see any sign of Gar Nal, Ur Jan, or Dejah Thoris; nor, indeed, was there any sign of life about the building or its grounds. The place might have been the abode of the dead.

"I am going to ground the ship beside Gar Nal's," I said. "Look to your weapons, Jat Or."

"They are ready, my--Vandor," he replied.

"I do not know how many fighting men are aboard that ship," I continued. "There may be only Gar Nal and Ur Jan, or there may be more. If the fight goes our way, we must not kill them all until we are positive that the princess is with them.

"They left Barsoom at least a full day ahead of us; and while it is only a remote possibility, still they may have made some disposition of their prisoner already. Therefore, we must leave at least one of them alive to direct us to her."

We were descending slowly. Every eye was on the alert. Zanda had stepped from the control room a moment before, and now she returned with the harness and weapons of a Martian warrior strapped to her slender form.

"Why those?" I asked.

"You may need an extra sword hand," she replied. "You do not know against how many foemen you will be pitted."

"Wear them, if you like," I said, "but remain in the ship where you will be safe. Jat Or and I will take care of the fighting."

"I shall go with you and fight with you," said Zanda, quietly but emphatically.

I shook my head. "No," I said; "you must do as I say and remain on this ship."

She looked me steadily in the eye. "Against my will, you insisted upon making me a free woman," she reminded me. "Now I shall act as a free woman and not as a slave. I shall do as I please."

I had to smile at that. "Very well," I said; "but if you come with us, you will have to take your chances like any other fighting man. Jat Or and I may be too busy with our own antagonists to be able to protect you."

"I can take care of myself," said Zanda, simply.

"Please stay on board," pleaded Jat Or solicitiously; but Zanda only shook her head.

Our ship had settled quietly to the ground beside that of Gar Nal. I caused the door in the port side to be opened and the ladder lowered. Still there was no sign of life either on the other craft or elsewhere about the castle. A deathly silence hung like a heavy mantle over the entire scene.

Just a moment I stood in the doorway looking about; and then I descended to the ground, followed by Jat Or and Zanda.

Before us loomed the castle, a strange weird building of unearthly architecture, a building of many towers of various types, some of them standing alone and some engaged in groups.

Partially verifying Fal Sivas's theory of the tremendous mineral wealth of the satellite, the walls of the structure before us were constructed of blocks of precious stones so arranged that their gorgeous hues blended and harmonized into a mass of color that defied description.

At the moment, however, I gave but cursory attention to the beauties of the pile, turning my attention instead to Gar Nal's ship. A door in its side, similar to that in our ship, was open; and a ladder depended to the ground.

I knew that in ascending that ladder, a man would be at great disadvantage if attacked from above; but there was no alternative. I must discover if there were anyone on board.

I asked Zanda to stand at a little distance, so that she could see into the interior of the ship and warn me if an enemy exhibited himself. Then I mounted quickly.

As the ship was already resting on the ground, I had only to ascend a few rungs of the ladder before my eyes were above the level of the cabin floor. A quick glance showed me that no one was in sight, and a moment later I stood inside the cabin of Gar Nal's ship.

The interior arrangement was slightly different from that of Fal Sivas's, nor was the cabin as richly furnished.

From the cabin, I stepped into the control room. No one was there. Then I searched the after part of the ship. The entire craft was deserted.

Returning to the ground, I reported my findings to Jat Or and Zanda.

"It is strange," remarked Jat Or, "that no one has challenged us or paid any attention to our presence. Can it be possible that the whole castle is deserted?"

"There is something eerie about the place," said Zanda, in low, tense tones.

"Even the silence seems fraught with suppressed sound. I see no one, I hear no one, and yet I feel--I know not what."

"It is mysterious," I agreed. "The deserted appearance of the castle is belied by the well-kept grounds. If there is no one here now, it has not been deserted long."

"I have a feeling that it is not deserted now," said Jat Or. "I seem to feel presences all around us. I could swear that eyes were on us--many eyes, watching our every move."

I was conscious of much the same sensation myself. I looked up at the windows of the castle, fully expecting to see eyes gazing down upon us; but in none of the many windows was there a sign of life. Then I called aloud, voicing the common peace greeting of Barsoom.
