Three days later Travis, Jil-Lee, and Buck came into the tower valley. Kaydessa was in the northern foothills, twice turned back from the west and the freedom of the outlaws by the Apache scouts. And only half an hour before, Tsoay had reported by mirror what should have been welcome news: the Red helicopter was cruising as it had on the day they watched the hunters enter the uplands. There was an excellent chance of the fugitive's being sighted and picked up soon.

Tsoay had also spotted a party of three Tatars watching the helicopter. But after one wide sweep of the flyer they had taken to their ponies and ridden away at the fastest pace their mounts could manage in this rough territory.

On a stretch of smooth earth Buck scratched a trail, and they studied it. The Reds would have to follow this route to seek the wrecked ship—a route covered by Apache sentinels. And following the chain of communication the result of the trap would be reported to the party at the towers.

The waiting was the most difficult; too many imponderables did not allow for unemotional thinking. Travis was down to the last shred of patience when word came on the second morning at the hidden valley that Kaydessa had been picked up by a Red patrol—drawn out to meet them by the caller.

"Now—the tower weapons!" Buck answered the report with an imperative order to Travis. And the other knew he could no longer postpone the inevitable. And only by action could he blot out the haunting mental picture of Kaydessa once more drawn into the bondage she so hated.

Flanked by Jil-Lee and Buck, he climbed back through the tower window and faced the glowing pillar.

He crossed the room, put out both hands to the sleek pole, uncertain if the weird transport would work again. He heard the sharp gasp from the others as his body was sucked against the pillar and carried downward through the well. Buck followed him, and Jil-Lee came last. Then Travis led the way along the underground corridor to the room with the table and the reader.

He sat down on the bench, fumbled with the pile of tape disks, knowing that the other two were watching him with almost hostile intentness. He snapped a disk into the reader, hoping he could correctly interpret the directions it gave.

He looked up at the wall before him. Three ... four steps, the correct move—and then an unlocking....

"You know?" Buck demanded.
