My plan was formulated and I lay awake upon my sleeping silks and furs in the darkness of my room, awaiting the time when I might put it into execution. My window, which was upon the third floor, overlooked the walled enclosure, upon the scarlet sward of which I had made my first bow to Barsoom. Across the open casement I had watched Cluros, the farther moon, take his slow deliberate way. He had already set. Behind him, Thuria, his elusive mistress, fled through the heavens. In five xats (about 15 minutes) she would set; and then for about three and three quarters Earth hours the heavens would be dark, except for the stars.
In the corridor, perhaps, lurked those watchful eyes. I prayed God that they might not be elsewhere as Thuria sank at last beneath the horizon and I swung to my window ledge, in my hand a long rope fabricated from braided strips torn from my sleeping silks while I had awaited the setting of the moons. One end I had fastened to a heavy sorapus bench which I had drawn close to the window. I dropped the free end of the rope and started my descent. My Earthly muscles, untried in such endeavours, I had not trusted to the task of carrying me to my window ledge in a single leap, when I should be returning. I felt that they would, but I did not know; and too much depended upon the success of my venture to risk any unnecessary chance of failure. And so I had prepared the rope.
Whether I was being observed I did not know. I must go on as though none were spying upon me. In less than four hours Thuria would return (just before the sudden Barsoomian dawn) and in the interval I must reach Valla Dia, persuade her of the necessity of my plan and carry out its details, returning to my chamber before Thuria could disclose me to any accidental observer. I carried my weapons with me and in my heart was unbending determination to slay whoever might cross my path and recognize me during the course of my errand, however innocent of evil intent against me he might be.
The night was quiet except for the usual distant sounds that I had heard ever since I had been here—sounds that I had interpreted as the cries of savage beasts. Once I had asked Ras Thavas about them, but he had been in ill humor and had ignored my question. I reached the ground quickly and without hesitation moved directly to the nearest entrance of the building, having previously searched out and determined upon the route I would follow to the vault. No one was visible and I was confident, when at last I reached the doorway, that I had come through undetected. Valla Dia was so happy to see me again that it almost brought the tears to my eyes.
“I thought that something had happened to you,” she cried, “for I knew that you would not remain away so long of your own volition.”
I told her of my conviction that I was being watched and that it would not be possible for me longer to bring food to her without incurring almost certain detection, which would spell immediate death for her.
“There is a single alternative,” I said, “and that I dread even to suggest and would not were there any other way. You must be securely hidden for a long time, until Ras Thavas’ suspicions have been allayed; for as long as he has me watched I cannot possibly carry out the plans I have formulated for your eventual release, the restoration of your own body and your return to Duhor.”
“Your will shall be my law, Vad Varo.”
I shook my head. “It will be harder for you than you imagine.”
“What is the way?” she asked.
