It was not the darkness of unconsciousness. He'd landed on his back, pulled by steel muscles into an arc that rocked the impact from his hurtling body.

But, somehow, a covering was over his eyes, and two men lay beside him, one on either side. They spoke softly to each other over his head in a language Barry recognized but could not understand; Martian!

He'd found the Martians all right, the hard way! But Grey and his men would ray them all out of existence in a matter of seconds. Overhead the rockets of the ore-king's ships thundered closer. They'd seen his body hurtle from the wreck, and were searching! He wished the Martians hadn't blindfolded him.

An intolerable glare from many ray beams beat through the covering over his eyes. This was it! The heat of those beams brought sweat through every pore of his body, but that was all. The drumming of rocket jets receded. They were leaving!

Why hadn't they seen him? They'd rayed his ship into a heap of molten metal that warmed him where he lay, yards away. But he and his captors were unhurt. Apparently, Grey and his men had decided they'd been wrong about seeing the investigator jump. They'd decided he was still in the wreckage. But why hadn't they seen Grey and the Martians?

The question was quickly answered. As the thrumming of rockets died in the distance, the two Martians pulled Barry to his feet. He blinked as sunlight struck his eyes, and looked about. The three of them were standing in the open, but a large square of rough cloth at their feet explained why the ships above hadn't spotted them. It was colored to blend into the red sand so perfectly it was almost invisible to Barry.

His respect for Martians leaped! A peaceful race they had been, before they were attacked and conquered. But now they were showing how fast they could learn. They'd mastered one of the most effective stratagems of warfare, camouflage.

The clothing of his Martian captors was the same color as the cloth that had covered them, even to masks over the face. One of them tugged at Barry's arm and spoke softly in Martian. They wanted him to go with them. He went gladly. If they took him to their headquarters, he'd have the chance he wanted—to ask their help, and offer them his! His heart was beating wildly. Grey and his followers would learn that Earth Government had an answer for fraud and injustice!

His respect for the Martians increased again, when he was taken through a cleverly concealed passage into a sand-swell. Inside was a rough room, ingeniously hewn and held from collapsing inward.
