"That's easy to understand," Scotty told the Filipino. "No one could blame you, Angel."

"You are good to say it," Angel replied. He seemed relieved.

Rick knew that they had made a friend by expressing their understanding. Before, Angel would have done his best because of Okola. Now, he thought, Angel would do his best because he knew they were friendly and understood how a man's pride can be hurt even when it is not his fault.

"We'd better start keeping an eye peeled," Scotty advised.

They flew in silence, inspecting the road below. There was almost no traffic. Since leaving Trinidad Valley they had seen only the Bontoc bus, a brilliant orange speck on the road below, and two jeeps. They had identified the gates easily. Once they passed a gate where a south-bound panel truck waited. Rick knew that the truck driver couldn't know what kind of vehicle he waited for, but from the air it could be seen that the Bontoc bus was the only moving thing between the two gates.

The Sky Wagon was just above the tops of a series of mountain peaks and steep ridges. The road clung to the sides of the peaks like a dusty brown ribbon. Rick turned up the heater a little because it was cold at eight thousand feet.

Then he lost the road. So did Angel and Scotty. Astonished, Rick circled. He picked up the road again, followed it, lost it once more.

"Where does it go?" he wondered.

"Let's go see," Scotty suggested.

Rick examined the terrain. Their quarry might be on the lost section of the road. He had the choice of going down for a look, or finding where the road emerged and circle for a while. He elected to go down.
