Now and then they could see an Igorot village far below, but this was mostly uninhabited country. On Scotty's map, not so far away, were great white patches marked with a single word: UNEXPLORED. It seemed incredible that after nearly fifty years of American Government and a few years of independence, the island of Luzon, seat of the capital, had unexplored areas. But it was true.

Rick knew that he need not watch the road carefully for a little while, except to follow it. If the truck and sedan were headed for Bontoc and Banaue they had a good start. He doubted that they were traveling together.

"You know," he said, "we're not so smart."

"I've always known it," Scotty replied. "But what have we done that's especially stupid?"

"We could have phoned the first gate and asked if the truck and sedan had passed through."

Scotty groaned. "You are so right!"

Angel spoke from the rear seat. "True, true! It is my fault. I am ashamed to you that I did not think of it."

Rick suspected that it hurt Angel to be so humble and admit that he was ashamed. He looked like a proud man, one used to holding his head high.

"We liked Nangolat," he said. "We thought he was Angel Manotok. He had all your papers. We didn't doubt him because he looked like a fine man. We were taken in, all right."

Angel seemed to cheer up a little. "Yes? Then perhaps you understand how it was easy for him to catch me and try to kill me when I also liked him and thought he was my friend."
