"Relax," Rick said, but he didn't really mean it. "It was just an idea he had that this Ifugao might be tied up with Angel. After all, Okola recommended Angel." He recognized the fallacy in his argument as soon as the words were out, but Scotty was already pointing to it.

"Yes. Angel is Okola's boy, and so is this Nangolat. What's more likely than their being close friends? Angel could be giving Nangolat a helping hand."

The taxi climbed the winding streets of Baguio, passed the American military rest camp and the Baguio residence of the American ambassador, and finally entered the airport.

One quick look around the field showed them that the truck was missing. The Sky Wagon was waiting by itself. On Rick's quick instructions the taxi raced to the plane. They got out and took a quick look.

"No sign of damage," Scotty said. "Let's ask at the airport office."

The office was closed. It was operated by Philippine Air Lines, and was only kept open during the day, starting one hour before the day's first flight to Manila or from the big city. The first flight on this day was not until ten thirty.

A pair of workmen with shovels were scratching listlessly at the gravel on the opposite side of the field. The boys jumped into the taxi and told the driver to cross the field.

Rick leaned out. "Did you see a truck?"

The men smiled and nodded.

"How long ago?" Rick called.
