She nodded, and I lowered her away. Presently the rope went slack, and I knew that she had reached the sill of the room below. I waited for her to unfasten it from her body; then I engaged the hook over the sill upon which I sat, and quickly descended to the room below.

I did not wish to leave the hook and the rope as they were, because, in the event that anyone should enter Ozara's cell above, this evidence would point immediately to the room below; and I did not know how long we might have to wait here.

As gently as possible, I shook the hook loose and was fortunate in catching it as it dropped and before it could scrape against the side of the tower.

As I entered the room, Ozara came close to me and placed her hands upon my breast. She was trembling, and her voice was trembling as she spoke.

"I was so surprised to see you, John Carter," she said. "I thought that you were dead. I saw them strike you down, and Ul Vas told me that they had killed you.

"What a terrible wound; I do not see how you recovered. When you faced me in the, room above and I saw the blood dried upon your skin and in your hair, it was as though a dead man had come back to life."

"I had forgotten what a spectacle I must present," I said. "I have had no opportunity to wash the blood from me since I was wounded. What little water they brought me barely sufficed for drinking purposes; but as far as the wound is concerned, it does not bother me. I am quite recovered; it was only a flesh wound."

"I was so frightened for you," she said; "and to think that you took that risk for me, when you might have escaped with your friends."

"You think they got away all right?" I asked.

"Yes," she replied, "and Ul Vas is very furious about it. He will make you and me pay, if we do not escape."

"Do you know of any way by which we can escape from this castle?" I asked her.

"There is a secret doorway, known only to Ul Vas and two of his most faithful slaves," she replied. "At least, Ul Vas thinks that only those three know of it; but I know. It leads out to the edge of the river where the waters lap the walls of the castle.

"Ul Vas is not well-liked by his people. There are plots and intrigues in the castle. There are factions that would like to overthrow Ul Vas and set up a new jeddak. Some of these enemies are so powerful that Ul Vas does not dare destroy them openly. These, he murders secretly; and he has his two faithful slaves carry the bodies to this secret doorway and cast them into the river.

"Once, suspecting something of the kind, I followed him, thinking that I might discover a way to escape and return to my own people in Domnia; but when I saw where the passage led, I was afraid. I would not dare to jump into the river; and even if I did, beyond the river there is a terrible forest. I do not know, John Carter, that we would be much better off either in the river or the forest than we are here."

"If we remain here, Ozara, we know that we shall meet death and that there will be no escape. In the river or the forest beyond, there will be at least a chance; for often wild beasts are less cruel than men."

"I know that all too well," she replied; "but even in the forest there are men, terrible men."

"Nevertheless, I must take the chance, Ozara," I told her. "Will you come with me?"

"Wherever you take me, John Carter, whatever fate befalls us, I shall be happy as long as I am with you. I was very angry when I learned that you loved that woman from Barsoom," she said; "but now she is gone, and I shall have you all to myself."

"She is my mate, Ozara."

"You love her?" she demanded.

"Of course," I replied.

"That is all right," she said, "but she is gone, and you are mine now."

I had no time to waste on such matters then. It was apparent that the girl was self-willed; that she had always had her own way, had everything that she wished, and could not brook being crossed, no matter how foolish her whim might be. At another time, if we lived, I might bring her to her senses; but now I must bend every effort to escape.

"How can we reach this secret doorway?" I asked. "Do you know the way from here?"

"Yes," she replied; "come with me."

We crossed the room and entered the corridor. It was very dark, but we groped our way to the stairs that I had ascended from the pit earlier in the day. When she started down these, I questioned her.

"Are you sure this is the right way?" I asked. "This leads to the cell in which I was imprisoned."

"Perhaps it does," she said; "but it also leads to a distant part of the castle, close to the river, where we shall find the doorway we are seeking."

I hoped that she knew what she was talking about as I followed her down the stairway and through the Stygian darkness of the corridor below.

When I had come through it before, I had guided myself by pressing my right hand against the wall at my side. Now Ozara followed the opposite wall; and when we had gone a short distance, turned into a corridor at our right that I had passed without knowing of its existence, because I had been following the opposite wall; and of course in the absolute darkness of the corridor, I had not been able to see anything.

We followed this new corridor for a long distance, but finally ascended a circular stairway to the next level above.

Here we came into a lighted corridor.

"If we can reach the other end of this without being discovered," whispered Ozara, "we shall be safe. At the far end is a false door that leads into the secret passageway ending at the door above the river."

We both listened intently. "I hear no one," she said.

"Nor I."

As we started down the long corridor, I saw that there were rooms opening from it on either side; but as we approached each door I was relieved to find that it was closed.

We had covered perhaps half the length of the corridor when a slight noise behind us attracted my attention; and, turning, I saw two men step from one of the rooms we had recently passed. They were turning away from us, toward the opposite end of the corridor; and I was breathing a sigh of relief, when a third man followed them from the room. This one, through some perversity of fate, glanced in our direction; and immediately he voiced an exclamation of surprise and warning.

"The Jeddara!" he cried, "and the black-haired one!"

Instantly the three turned and ran toward us. We were about halfway between them and the door leading to the secret passage that was our goal.

Flight, in the face of an enemy, is something that does not set well upon my stomach; but now there was no alternative, since to stand and fight would have been but to insure disaster; and so Ozara and I fled.

The three men pursuing us were shouting at the tops of their voices for the evident purpose of attracting others to their assistance.

Something prompted me to draw my long sword as I ran; and it is fortunate that I did so; for just as we were approaching a doorway on our left, a warrior, attracted by the noise in the corridor, stepped out. Ozara dodged past him just as he drew his sword. I did not even slacken my speed but took him in my stride, cleaving his skull as I raced past him.

Now we were at the door, and Ozara was searching for the secret mechanism that would open it to us. The three men were approaching rapidly.

"Take your time, Ozara," I cautioned her, for I knew that in the haste of nervousness her fingers might bungle the job and delay us.

"I am trembling so," she said; "they will reach us before I can open it."

"Don't worry about them," I told her. "I can hold them off until you open it."

Then the three were upon me. I recognized them as officers of the Jeddak's guard, because their trappings were the same as those worn by Zamak; and I surmised, and rightly, that they were good swordsmen.
