He gestured with the boots. Four steps-five-side by side they crept down. Kimber drew his stun gun and fired. The noiseless charge of the ray hit its mark. The man on the bench twisted, turning a horribly contorted face to them before he fell to the floor.
In that same instant Kimber hurled himself out and down. There was one startled shout as Dard went out into space too. Then the boy struck another body and they went to the floor together in a kicking clawing fury. Dodging a blow Dard brought his boots down club fashion in the other’s face. He struck heavily three times before hands clutched his shoulders and wrenched him off the now limp man. Kimber, a raw and bleeding scrape over one eye, shook him out of the battle madness.
Dard’s eyes focused on the pilot as the terrible anger drained out of him. They tied the limp bodies with the men’s own belts and lacings before Kimber took his place on the bench before the Voice.
He pulled a much-creased sheaf of papers from the breast of his blouse and spread them out on the sloping board beneath the first rank of push buttons. Dard fidgeted thinking the pilot was taking entirely too long over that business.
But the boy had sense enough to keep quiet as Kimber rubbed his hands slowly together as if to clear them of moisture before raising his eyes to study the row upon row of buttons, each marked with a different symbol. Slowly, with a finicky touch and care, the pilot pressed one, another, a third. There was a change in the hum of the Voice, a faster rhythm; the great machine was coming to life.
Kimber picked up speed, stopping only now and again to consult his scrawled notes. His fingers were racing now. The hum deepened to a throb which, Dard feared, must certainly be noticeable in the Temple overhead.
The boy withdrew to the stairway, his attention as much on the door at the top as on Kimber. He drew his gun. As Kimber had said, the mechanism of the arm was childishly simple-one pointed it, pushed the button on the grip-easy. And he had two charges to use. Caressing the metal he looked back at the Voice.
Under the light Kimber’s face displayed damp drops, and now and again he rubbed his hand across his eyes. He was waiting-his part of the job finished-waiting for the Voice to assimilate the data fed it and move in its ponderous way to solve the problem. But every minute they were forced to linger added to the danger of their position.
One of the captives rolled over on his side, and, over the gag they had forced into his jaws, his eyes blared red hate at Dard. The hum of the Voice faded to a lulling murmur. There was no other sound in the cavern. Dard crossed to touch Kimber’s shoulder.
“How long?” he began.
