This information also interested me greatly since I thought that I saw where it too might have considerable bearing upon my plan of escape, and so, as we descended the runway, I encouraged Ras Thavas to discourse upon the construction of the tower, its relation to the other buildings and especially its accessibility from the pits. We walked again in the outer garden and by the time we returned to Ras Thavas’ quarters it was almost dark and the master surgeon was considerably fatigued. “I feel that I shall sleep well to-night,” he said as I left him. “I hope so, Ras Thavas,” I replied. CHAPTER VII ESCAPE It was usually about three hours after the evening meal, which was served immediately after dark, that the establishment quieted down definitely for the night. While I should have preferred waiting longer before undertaking that which I had in mind, I could not safely do so, since there was much to be accomplished before dawn. So it was that with the first indications that the occupants of the building in which my work was to be performed had retired for the night, I left my quarters and went directly to the laboratory, where, fortunately for my plans, the bodies of Gor Hajus, the assassin of Toonol, and 378-J-493811-P both reposed. It was the work of a few minutes to carry them to adjoining tables, where I quickly strapped them securely against the possibility that one or both of them might not be willing to agree to the proposition I was about to make them, and thus force me to anaesthetize them again. At last the incisions were made, the tubes attached and the motors started. 378-J-493811-P, whom I shall hereafter call by his own name, Dar Tarus, was the first to open his eyes; but he had not regained full consciousness when Gor Hajus showed signs of life. I waited until both appeared quite restored. Dar Tarus was eyeing me with growing recognition that brought a most venomous expression of hatred to his countenance. Gor Hajus was frankly puzzled. The last he remembered was the scene in the death chamber at the instant that his executioner had run a sword through his heart. It was I who broke the silence. “In the first place,” I said, “let me tell you where you are, if you do not already know.” “I know well enough where I am,” growled Dar Tarus. “Ah!” exclaimed Gor Hajus, whose eyes had been roaming about the chamber. “I can guess where I am. What Toonolian has not heard of Ras Thavas? So they sold my corpse to the old butcher did they? And what now? Did I just arrive?” “You have been here six years,” I told him, “and you may stay here for ever unless we three can reach an agreement within the next few minutes, and that goes for you too, Dar Tarus.”
