Realizing that the instant that I emerged from the interior of the flier I should be entirely visible, I waited, watching through my periscope until the warrior upon the roof just below me turned his back; then I emerged quickly from the ship through one of the upper hatches and dropped to the roof upon the side closest to the warrior. I was about four feet from the edge of the roof and he was standing almost below me, his back toward me. Should he turn he would discover me instantly and would give an alarm before I could be upon him. My only hope of success, therefore, was to silence him before he realized that he was menaced. I have learned from the experiences of John Carter that first thoughts are often inspirations, while sober afterthought may lead to failure, or so delay action as to nullify all its effect. Therefore, in this instance, I acted upon inspiration. I did not hesitate. I stepped quickly to the edge of the roof and hurled myself straight at the broad shoulders of the sentry. In my hand was a slim dagger. The end came quickly. I think the poor fellow never knew what happened to him. Dragging his body to the interior of the hangar I stripped the harness from it, at the same time, though almost mechanically, I noted the ships within the hangar. With the exception of one, a patrol boat, they all bore the personal insignia of the Jed of Tjanath. They were the king's ships--an ornate cruiser heavily armed, two smaller pleasure crafts, a two-man scout flier and a one-man scout flier. They were not much, of course, by comparison with the ships of Helium, but I was quite sure that they were absolutely the best that Tjanath could afford. However, having my own ship, I was not particularly concerned with these other than that I am always interested in ships of all descriptions. Not far from where I stood was the entrance to a ramp leading down into the palace. Realizing that only through boldness might I succeed, I walked directly to the ramp and entered it. As I rounded the first turn I was appalled to see that the ramp passed directly through a guard room. Upon the floor fully a score of warriors were stretched upon their sleeping silks and furs. I did not dare to pause; I must keep on. Perhaps I could pass them without arousing their curiosity. I had had but a brief glimpse of the room before I entered it, and in that glimpse I had seen only men apparently wrapped in sleep and an instant later, as I emerged into the room itself, I saw that it contained only those whom I had first seen. No one within it was awake, but I heard voices in an adjoining room. Hurrying quickly across the apartment I entered the ramp upon the opposite side. I think my heart had stood still as I strode silently across that room among those sleeping men, for had a single one of them awakened he would have inevitably known that I was no fellow member of the guard.
