Hekalu Selba's face gave no hint of anger; in fact he seemed at the point of laughing. "You have done as I expected you would. Your refusal shows me how patriotic you are and gratifies me very much, Mr. Shelby," he said blandly. "You are as a man of Earth should be. However, there is another side to the question. I have certain plans and to have you at large might endanger their fulfillment. Therefore I must ask you to accompany me on a little trip. That weapon of yours will be well taken care of. Now, kindly raise your hands high above your head." The Martian was pointing a bejeweled automatic straight at the chest of his visitor. "You are being covered from two other points in this room so try not to cause any misunderstanding," he added. Shelby saw the wisdom of obeying the order for he felt quite certain that Hekalu Selba and his minions would not hesitate to shoot him down. What a colossal idiot he had been! He had sensed a trap when the noble had called him over the view-phone and yet he had taken no sensible precautions! Hekki was searching him now. His long fingers were moving deftly from pocket to pocket. They closed upon his automatic and drew it forth. "Ah," the Martian breathed, "it's as I thought. You have brought a souvenir. A most worthy precaution. And, now that you are no longer in a position to cause any trouble," he continued sneeringly, "I may as well tell you about my ambition--Oh, it is simple enough; men have thought of it before but none had the nerve or ability to put it over. Briefly it is this--to become Master of both Earth and Mars! My friends are waiting for me out there beyond the Red Planet--waiting for their commander. And there is another little hope--there is a certain beautiful flower of your race--" Here he stopped to allow his captive to imagine the rest. A hard light came into Austin Shelby's eyes. It was the only outward indication of the sudden tornado of emotions and thoughts that swirled in his mind. This man sought to enforce his will upon the planets! The question of whether he was capable of realizing this tremendous dream or not, the Earthman did not pause to debate. Fifty years before, Saranov had attempted it, and as a result a score of great cities became shambles. Certainly the present foe of mankind was more powerful than Saranov. The monstrous associate of Hekalu and the flitting specks of light far beyond Mars seemed to bear out the nobleman's boast. And if he somehow got possession of the Atomic Ray! And Jan--What was he going to do to Jan! Certainly it was she to whom he had referred! It was this last idea which hammered on Shelby's brain hardest of all. A little fiend within him seemed to shriek. "Escape! Send your weapon to the War Office! Kill Selba if you can, for everything is at stake!" Escape, yes, but how? "Place your wrists together behind your back now," Hekalu was saying. "I have a pair of magnificent manacles--careful. Do not make an abrupt movement."
