"You get off here!" Balta said, and Murray felt the muzzle of the neuro-pistol on his spinal column.

A grinning soldier seized a countersunk ring and raised the trap-door.

"So you're going to murder me," Murray said, speaking calmly.

"I take no chances," was Balta's short answer. "Step!"

Murray stepped, swaying like a man in deadly fear. He lowered his feet through the hole. Looking down, he saw that they were about to pass over a bitter salt lake, occasionally found in the Martian desert. He looked up into the muzzle of the menacing neuro-pistol.

"Balta, you're a dog!" he stated coldly.

"A live dog, anyway," the other remarked with a twisted grin. "You know the saying about dead lions."

Murray's fingers clenched on the edge of the rug. It was thin and strong, woven of fine metal threads. They were just over the edge of the salt lake.

Murray dropped through, but retained his death-like grip on the rug. It followed jerkily, as the men above tripped, fell, and rolled desperately clear.
