Then there were metal and rubber. Metal in his belt, in Lehn's belt; metal mesh, because the damp air rotted everything else. Rubber on his feet, on Lehn's feet. Rubber was insulation. Metal was a conductor.

MacIan realized with part of his mind that he must be mad to do what he planned to do. But he went to work just the same.

Ten minutes later he left the hut and crossed the soaking clearing in the downpour. Thekla had left the liha-tree for a hut directly opposite Lehn's; he rose warily in the doorway, gun ready. His sly black eyes took in MacIan's wild blue gaze, the fever spots burning on his lean cheekbones, and he smiled.

"Get on back to the hut," he said. "Be a pity if you die before the Nahali have a chance to try electro-therapy."

MacIan didn't pause. His right arm was hidden behind his back. Thekla's jaw tightened. "Get back or I'll kill you!"

MacIan's boots sucked in the mud. The beating rain streamed from his white hair, over his craggy face and gaunt shoulders. And he didn't hesitate.

Thekla's pointed teeth gleamed in a sudden snarl. His thumb snapped the trigger; a bolt of blue flame hissed toward the striding Scot.

MacIan's right hand shot out in the instant the gun spoke. One of Lehn's rubber boots cased his arm almost to the shoulder, and around the ankle of it a length of metal was made fast; two mesh belts linked together. The spitting blue fire was gathered to the metal circle, shot down the coupled lengths, and died in the ground.

The pistol sputtered out as a coil fused. Thekla cursed and flung it at MacIan's head. The Scot dodged it, and broke into a run, dropping Lehn's boot that his hands might be free to grapple.

Thekla fought like a low-canal rat, but MacIan was bigger and beyond himself with the first madness of fever. He beat the little Martian down and bound him with his own belt, and then went looking for his clothes and gun.
