territory. Already Australia and Asia had fallen. With every known device of interplanetary warfare, the Sirians had captured district after district, until the American continent alone remained untrampled by the invaders. But Standish's story had begun a week before. Through an operative in his vast espionage system, he had learned that the Sirians under command of the ruthless Drum Faggard, were preparing for the "big push." With a dozen chosen companions disguised as Sirians, the Earth engineer had successfully passed through the enemy lines. He had hoped to capture Drum Faggard and a number of his officers-of-staff and race with them back to the Earth's front line breastworks at Omaha. It was a wild scheme; but Standish knew if Faggard were captured, the war would collapse. The plan had failed. Counter-spies had warned the Sirians.

"What sort of questions?" Standish had demanded. Faggard smiled again. "Now that your connections with Earth have been forever severed, it can be of little concern to you what happens to that planet. What I want to know is this: How many anti-rocket guns has Earth located at its Omaha base? What is the number of strato-cruisers stationed at Powerville? How heavy are the
