She seemed not to hear. A distant look entered her blue eyes. "Tell me, Mr. Dulfay, have you ever heard of an artifact kept here in Klovada known as the Jupiter Stone?" I went slowly rigid. The girl breathed deeply and continued. "Some time ago a great scientist communicated with me as overchief of power-control of the seven cities and outlined a plan similar to the one in which you are now engaged. He was a great man, but under stress of excessive work, his mind broke. He was taken to a mental hospital, where I am told he is now known by the simple name of Hol-Dai. "Before his illness Hol-Dai worked out a method to overcome the plague. It was simple. A person would visit each of the seven cities. He would have temporary protection against the plague, but of course he would become a carrier for the germs. When he finally reached Klovada, the final city, he would be a walking vial of the bacillus in all its seven forms. "Now the Jupiter Stone, of which I spoke before. It is a great thing, capable of generating untold amounts of power, if properly harnessed. So far, however, the scientists have been unable to move it because it lies protected by a small but peculiar form of space warp. But the stone has other potentialities. This man, Hol-Dai, discovered that it will transform the plague bacillus from a positive form to a negative form. "In other words if this hypothetical visitor of the seven cities were, at the end of his journey, to expose himself to the radiations of the Jupiter Stone, a curious event would take place. He would become a carrier for bacilli which, when released, would immediately begin to combat the plague. Practically an anti-toxin, you see. Again, continuing our hypothetical case, if this man were to retrace his steps, again visiting each of the seven cities, it is estimated this action would result in the complete end of the plague within a period of months." "I see," I said. Far back in a corner of my mind a doubt was beginning to grow. "Why hasn't this been done before?" She smiled. "Because until you came no one knew how to acquire temporary protection against the disease and no one had the courage to expose himself to it without that protection. Now I am aware that you have found that protection. But as you must know, if you let yourself be struck by the radiations of the Jupiter Stone, you would die within six weeks!" "You mean...?" "I mean that if you go through with your role as Tepondicon you will never live to know your glory." <tb> She tapped her pencil on the desk. "I might add that Hol-Dai also told us of a plan to nullify the space warp surrounding the Jupiter Stone. Since his sickness, however, that plan has remained a mystery." I breathed easier. So Hol-Dai had not tricked me. But this girl with all her babbling of curing the plague must be an utter fool. What did I care about cure? It was the stone I wanted!
