But I still had Xenora. As we walked, I put my arms around her, protectingly, in the grim determination that this strange world should not rob me also of the dream girl for whom I had searched two worlds. My love of her kept me from utter despair, but even then I knew that our ideal life could not go on. I would have to find what it was that had taken Sam--to identify the thing that Xenora called so vaguely "the menace of the purple wood." Might it be the wild plant monsters, or was it something even more alien and terrible? And I thought more seriously of the danger to the earth, that I had been trying so vainly to forget. Sam's responsibility had fallen on my shoulders. I must see what I could do. With the wonderful intuitive knowledge of one another's thoughts that Xenora and I have always had, she understood what was passing in my mind before I said anything. Softly, she took my fingers in her hand, and looked at me with deep sympathy in her eyes. "I know, Melvin, what you think. And it is right. It is hard, so soon after you have come here to find me--but it must be. I can guide you to the city of my people. I can even show you to the brink of the pit of Xath, if you would go there!" "You are very brave and true, my princess!" "I come from Lothar! If you feel that your duty bids you risk the violet death in Xath, I would not dissuade you. But the Lord of Flame is mighty--no man can fight him! He has power over all!" "Except our love," I said. I stopped, and took her in my arms, and pressed her red warm lips against my own. In the whole world, she was all that was mine. She clung to me fiercely, as if the terrible power of the pit of flames was trying to tear her away. At last we went on, and presently we reached the Omnimobile, hidden in the purple grove. In Sam's absence, it looked very cheerless and lonely. We got aboard and made ready for departure. I tuned up the motors, and examined the electric weapons, and cleaned and loaded the little cannon again. As I worked, Xenora went in the galley and fixed a lunch. We ate quickly, under the silent pall of bitter tragedy, thinking of the smiling old man that should have been with us. Then we climbed into the conning-tower, and I switched on the engines. The humming of the generators rose again, and the great machine lumbered clumsily out of the little wood, where it had been hidden for so many happy days. For many hours we held a north-westward course over the green plateaus and through the purple woodlands, with the light of the crimson day shining through the ports. Xenora stood by me and chose the route. For the last few miles we crept along just east of a high, bare ridge of rocks. At last she bade me stop the machine in a clump of trees at the foot of the hill. The last city of Lothar, she said, lay but a mile beyond.
