"Curt!" It was Lorine's whispered voice in the doorway behind him. He felt the grip of an electro pressed into his hand.

"We had a fighting chance, Tor," Curt grated, "but you've ruined that! The Zemmd has contacted us. He'll send his men down here. Yes, we'll die!" He brought the electro unobserved to his side. "And you'd leave the entire Federation prey to these things because of your damned stupid fanaticism about Mars!"

"Don't try to stop me!" With his free hand Tor brought the Martian scene sharper into focus. Nothing else mattered to him.

"A last chance, Tor! You can reach Earth on that thing. Let me contact Earth and warn them of what goes on here! Even if we die, they can send the Fleet and blast this place—"

Curt saw it was no use.

He brought his gun around fast, tried a snap shot from the waist. But Tor was faster. He swayed aside, then his own electro sent its beam.

Curt's arm went numb from wrist to shoulder, as the Martian's beam caught his gun squarely and sent it spinning from his grasp. Curt dived low, in a try for the radiant-rifle a few yards away. Again Tor blasted. A spray of molten froth from the floor sent Curt tumbling back. He poised for another try. To think of failure now was to think of death!

But he had failed. This was death!

He heard Lorine cry out, heard Jeffers cursing behind him, as a rush of feet came toward them down the corridor!
