"Phor Tak," I said, "you hold here within your grasp two secrets which in the hands of a kindly and beneficent power would bring eternal peace to Barsoom."
"Heigh-oo!" he cried. "I do not want peace. I want war. War! War!"
"Very well," I agreed, realizing that my suggestion had not been in line with the mad processes of his crazed brain. "Let us have war then, and what country upon Barsoom is better equipped to wage war than Helium? If you want war, form an alliance with Helium."
"I do not need Helium," he cried. "I do not need to form alliances. I shall make war-I shall make war alone. With the invisible Flying Death I can destroy whole navies, whole cities, entire nations. I shall start with Jahar. Tul Axtar shall be the first to feel the weight of my devastating powers. When the fleet of Jahar has tumbled upon the roofs of Jahar and the walls of Jahar have fallen about the ears of Tul Axtar, then shall I destroy Tjanath. Helium shall know me next. Proud and mighty Helium shall tremble and bow at the feet of Phor Tak. I shall be Jeddak of Jeddaks, ruler of a world." As he spoke his voice rose to a piercing shriek and he trembled in the grip of the frenzy that held him.
He must be destroyed, not alone for the sake of Helium, but for the sake of all Barsoom; this mad mind must be removed if I found that it was impossible to direct or cajole it to my own ends. I determined, however, to omit no sacrifice that might tend to bring about a satisfactory conclusion to this strange adventure. I knew that mad minds were sometimes fickle minds and I hoped that in a moment of insane caprice Phor Tak might reveal to me the secret of The Flying Death and the compound of invisibility. This hope was his temporary reprieve from death; its fulfillment would be his pardon, but I knew that I must work warily-that at the slightest suggestion of duplicity, Phor Tak's suspicions would be aroused and that I should then be the one to be destroyed.
I tossed long upon my sleeping silks and furs that night in troubled thought and planning. I felt that I must possess these secrets; yet how? That they existed within his brain alone, I knew, for he had told me that there were no written formulas, or plans or specifications for either of them. Somehow I must wheedle them out of him and the best way to start was to ingratiate myself with him. To this end I must further his plans insofar as I possibly could.
Just before I fell asleep my thoughts reverted to Sanoma Tora and to the urgent mission that had led me to enter upon what had developed into the strangest adventure of my career. I felt a twinge of self-reproach as I suddenly realized that Sanoma Tora had not been uppermost in my mind while I had lain there making plans for the future, but now with recollection of her a plan was suggested whereby I might not only succor her but also advance myself in the good graces of Phor Tak at the same time, and, thus relieved, I fell asleep.
It was late the following morning before I had an opportunity to speak with the old inventor when I immediately broached the subject that was uppermost in my mind. "Phor Tak," I said, "you are handicapped by lack of knowledge of conditions existing in Jahar and the size and location of the fleet. Nur An and I will go to Jahar for you and obtain the information that you must have if your plans are to be successful. In this way, Nur An and I will also be striking a blow at Tul Axtar while we will be in a position to attend to those matters which require our presence in Jahar."
"But how will you get to Jahar?" demanded Phor Tak.
"Could not you let us take a flier?" I asked.
"I have none," replied Phor Tak. "I know nothing about them. I am not interested in them. I could not even build one."
To say that I was both surprised and shocked would be putting it mildly, but if I had previously entertained any doubts that Phor Tak's brain was abnormally developed, it would have vanished with his admission that he knew nothing about fliers, for it seemed to me that there was scarcely a man, woman or child in any of the flying nations of Barsoom but could have constructed some sort of a flier.
"But how without fliers did you expect to transport The Flying Death to the vicinity of the Jaharian fleet? How did you expect to demolish the palace of Tul Axtar, or reduce the city of Jahar to ruins?"
"Now that you and Nur An are here to help me, I can set my slaves to work under you and easily turn out a dozen torpedoes a day. As these are completed they will immediately be launched and eventually they will find their way to Jahar and the fleet. Of that there is no doubt, even if it takes a year they will eventually find their prey."
"If nothing chances to get in their way," I suggested; "but even so what pleasure will you derive from your revenge if you are unable to witness any part of it?"
"Heigh-oo! I have thought of that," replied Phor Tak, "but one may not have everything."
"You may have that," I told him.
"And how?" he demanded.
"By taking your torpedoes aboard a ship and flying to Jahar," I replied.
"No," he exclaimed stubbornly, "I shall do it my own way. What right have you to interfere with my plans?"
"I merely want to help you," I said, attempting to mollify him by a conciliatory tone and attitude.
"And there is another thought," said Nur An, "that suggests that it might be expedient to follow Hadron's plans."
"You are both against me," said Phor Tak.
"By no means," Nur An assured him. "It is our keen desire to aid you that prompts the suggestion."
"Well, what is yours then?" asked the old man.
"Your plan contemplates the destruction of the navies of Tjanath and Helium following the fall of Jahar," exclaimed Nur An. "This, at least in respect to the navy of Helium, you cannot possibly hope to accomplish at so great a distance and without any knowledge of the number of ships to be destroyed, nor will your torpedoes be similarly attracted to them as they are to the ships of Jahar because the ships of these other nations are not protected by the blue paint of Jahar. It will, therefore, be necessary for you to proceed to the vicinity of Tjanath and later to Helium and for your own protection you will use the blue paint of Jahar upon your ship, for you may never be certain unless you are on the ground at the time that you have destroyed all of the navy of Jahar, or all of their disintegrating ray rifles."
"That is true," said Phor Tak thoughtfully.
"And furthermore," continued Nur An, "if you dispatch more than the necessary number of torpedoes, those that remain at large will certainly be attracted by the blue paint of your own ship and you will be destroyed by your own devices."
"You ruin all my plans," screamed Phor Tak. "Why did you think of this?"
"If I had not thought of it you would have been destroyed," Nur An reminded him.
"Well, what am I to do about it? I have no ship. I cannot build a ship."
"We can get you one," I said.
"How?"
The conversation between Nur An and Phor Tak had suggested a plan to me and this I now explained roughly to them. Nur An was enthusiastic over the idea, but Phor Tak was not particularly keen for it. I could not understand the grounds for his objection, nor, as a matter of fact, did they interest me greatly since he finally admitted that he would be compelled to act in accordance with my suggestion.
Immediately adjacent to Phor Tak's laboratory was a well equipped machine shop and here Nur An and I labored for weeks utilizing the services of a dozen slaves until we had succeeded in constructing what I am sure was the most remarkable-looking airship that it had ever fallen to my lot to behold. Briefly, it was a cylinder pointed at each end and closely resembled the model of The Flying Death. Within the outer shell was another smaller cylinder; between the walls of these two we placed the buoyancy tanks. The tanks and the sides of the two envelopes were pierced by observation ports along each side of the ship and at the bow and stern. These ports could be completely covered by shutters hinged upon the outside, but operated from within. There were two hatchways in the keel and two above which led to a narrow walkway along the top of the cylinder. In turrets, forward, and aft were mounted two disintegrating ray rifles. Above the controls was a periscope that transmitted an image of all that came within its range to a ground glass plate in front of the pilot. The entire outside of the ship was first painted the ghastly blue that would protect it from the disintegrating ray rifles of Jahar, while over this was spread a coating of the compound of invisibility. The shutters that covered the ports being similarly coated, the ship could attain practically total invisibility by closing them, the only point remaining visible being the tiny eye of the periscope.
