"We're both through now, both of us!" The younger man saw Hume glance around him with waking belief.

"But how—?"

"I knocked you out, that's how," Vye returned.

"Knocked me out? I crossed when I was unconscious!" Hume's voice steadied, strengthened. "Let me see!" He rolled over on his side, threw out his arm, and this time the hand found no wall. For him, too, the barrier was gone.

"Once through, you are free," he added wonderingly. "Maybe they never foresaw any escapes." He struggled up, sitting with his hands hanging loosely between his knees.

Vye turned his head, looked down the trail. The length of distance lying between them and the safari camp now faced them with a new problem. Neither of them could make that trek on foot.

"We're out, but we aren't back—yet," Hume echoed his thought.

"I was wondering, if this door is open—" Vye began.

"The flitter!" Again Hume's mind matched his. "Yes, if those globes aren't hanging around just waiting for us to try."

"They might act only to get us here, not to keep us once we're in." That might be wishful thinking, they wouldn't know until they tried to prove it.
