"Nobody knows where he lives, unless it be the jeddak. They say he has a secret apartment in the palace, but I don't know about that. What I do know is that he's the most powerful man in Kamtol, next to Doxus; and that he has the power of life and death over every man and woman in the Valley of the First Born. Why, he could strike either one of us dead right while we are sitting here talking; and we'd never see what killed us."

I was even more convinced now than I had been before that I had found what I had hoped to in that secret room beneath the palace but how to utilize the knowledge!

I immediately took advantage of my freedom to go out into the city, only a part of which I had seen during the short time that I had been out with Ptang. The guards at the palace gate were as surprised when they read my pass as Man-lat had been. Of course, pass or no pass, I was still an enemy and a slave—a person to be viewed with suspicion and contempt; but in my case the contempt was tempered by the knowledge that I had bested their best at swordsmanship. I doubt that you can realize in what high esteem a great swordsman is held everywhere on Mars. In his own country he is worshipped, as might be a Juan Belmonte in Spain or a Jack Dempsey in America.

I had not gone far from the palace, when I chanced to look up; and, to my surprise, saw a number of fliers dropping down toward the city. The First Born I had seen in the Valley Dor had all been flying men; but I had not before seen any fliers over the valley, and I had wondered.

Martian aeroplanes, being lighter than air, or in effect so; because of the utilization of that marvellous discovery, the ray of repulsion, which tends to push them away from the planet, can land vertically in a space but little larger in area than themselves; and I saw that the planes I was watching were coming down into the city at no great distance from the palace.

Fliers! I think that my heart beat a little faster at the sight of them. Fliers! A means of escape from the Valley of the First Born. It might take a great deal of scheming; and would certainly entail enormous risks; but if all went well with the other part of my plan, I would find a way—and a flier.
