The crack of rifle fire punctuated the whine of the engine. Again he watched splinters fly—one close enough to score his cheek. By will alone he held himself immovable and kept Dessie captive, though her little body flinched at the sound of each shot. Those above could not see their quarry or they would not be spraying bullets so indiscriminately. This raking of the brush was to force him out.

And the worst of it was that they could do just that! Dard knew that the searching stream of death quartering the thicket would either kill them or force them to move.

He blinked at the bushes and made his first constructive move, stripping Lotta’s scarf off Dessie’s head and shoulders. Quickly he tangled the thick wool in some thorned branches. Then he put Dessie on her knees in the snow and pushed her away from that thorn bush. She obediently wormed her way off[as Dard followed, moving by inches. Luckily the ’copter was now making the rounds of the perimeter of the thicket and for a minute or two there had been no shooting. Dard traveled on until the scarf end pulled taut in his hand, until he could keep his grip on the loose end only with thumb and forefinger at the full extent of an outstretched arm. Then he lay waiting.

The ’copter was moving in again while more than one marksman added to a crisscross fire. Dard bit deep on the soft inner side of his lip. Now! By the sound the ’copter was just in the right position. As a rifle cracked, Dard gave two quick jerks of the scarf, and was answered by a loud burst of fire. Then he screamed wildly, and Dessie, shocked out of her bewilderment, echoed him thinly. Another tug at the scarf for good measure and then he was racing on hands and knees, bumping Dessie before him. If they would only believe that he, or Dessie, or both had been hit! That should bring them down, set them fighting their way to the spot where he had fastened the scarf. And then there would be a slim chance, a terribly slim chance, to get away.

Dard cringed at the sound of the vicious attack the ’copter riders were still centering behind him—an attack delivered without any call to surrender. All that blind hatred which had boiled over during the purge was still smoldering in those who were now hunting them. He had always known that anyone of proven scientist blood would have little chance if the Peacemen tracked him down, but now the last faint hope of mercy for the helpless was gone.

Pulling Dessie he reached the end of the thicket in which they bad taken refuge. By some blind chance they had come out on the side which faced the peak. But before them lay a wide open sweep of ground, impossible to cross undetected. Dard faced it bleakly. The brightness of the sunlight somehow made that last blow harder.

But, even as his misery and despair weakened him, he suddenly noted again flashes of light on the peak-coming in too regular a pattern to be sun fostered. While he was still gaping up at that, a shadow swept over. The ’copter landed directly on that virgin expanse of snow before him. He sagged and his arms tightened about Dessie who gave a muffled cry as his grip hurt her. This was the end—the could not run any more.

The Peacemen were taking their time about leaving the ’copter. It looked as if they were still reluctant to approach that thicket. What had Sach done that made them so wary?

Two of them crept around the tail of the machine, and Dard saw the gun mounted on the ’copters’ roof swing about to cover them. The men crawled slowly through the snow. But before they had reached beyond the length of the ’copter, that blink of light on the peak stepped up into a steady glow. Dard’s eyes dropped from it to the Peacemen and so he did not see deliverance arrive.

There was a swish of sound followed by a tinkle as if glass had splintered. Green fog bellowed out about the machine—the same fatal green of the ray Sach had used on the cave slope.
