"But I didn't have any escape gadgets." Ross was struck by the unfairness of that.

"No," Ashe agreed, his voice even and cold, "they are not entrusted to first-run men. You might slip up and use them at the wrong moment. However, you appear to have done fairly well...."

The heat of Ross's rising anger was chilled by the noise which cracked over their heads, ground to them through the walls, flattened and threatened them. He had thought those first shocks the end of this ice burrow and the world; he knew that this one was.

And the silence that followed was as threatening in its way as the clamor had been. Then there was a shout, a shriek. The space of light near the cell door was widening as that barrier, broken from its lock, swung open slowly. The fear of being trapped sent the men in that direction.

"Out!"

Ross was ready enough to respond to that order, but they were stopped by a crackle of sound that could be only one thing—rapid-fire guns. Somewhere in this warren a fight was in progress. Ross, remembering the arrogant face of the bald ship's officer, wondered if this was not an attack in force—the aliens against the looting Reds. If so, would the ship people distinguish between those found here. He feared not.

The room outside was clear, but not for long. As they lay watching, two men backed in, then whirled to stare at each other. A voice roared from beyond as if ordering them back to some post. One of them took a step forward in reluctant obedience, but the other grabbed his arm and pulled him away. They turned to run, and an automatic cracked.

The man nearest Ross gave a queer little cough and folded forward to his knees, sprawling on his face. His companion stared at him wildly for an instant, and then skidded into the passage beyond, escaping by inches a shot which clipped the door as he lunged through it.

No one followed, for outside there was a crescendo of noise—shouting, cries of pain, an unidentifiable hissing. Ashe darted into the room, taking cover by the body. Then he came back, the fellow's gun in his hand, and with a jerk of his head summoned the other two. He motioned them on in a direction away from the sounds of battle.

"I don't get all this," McNeil commented as they reached the next passage. "What's going on? Mutiny? Or have our boys gotten through?"
