Scotty spoke for the first time. He addressed Nast. "Because you're a fellow American I thought the decent thing to do would be just to kill you outright."

Nast shuddered visibly. "You're both joking, of course. But it isn't a very funny joke, I a.s.sure you."

Rick smiled. "No, it isn't very funny. But neither is Dr. Briotti's disappearance. You'd better tell us where he is."

"What makes you think Mr. Nast knows?" Lazada asked.

Rick considered. They had no proof. No one had seen Nast in the sedan that had taken Tony from the airport. The boys saw movement at the entrance to the dining room and realized that two Filipinos were watching them like hawks, and that the hands in their pockets certainly held pistols.

Rick shifted tactics. "Do you have much faith in your bodyguards?"

Lazada raised his eyebrows. "Faith? Of course. They are loyal to me. If anyone tries to get close to me without my permission, they step in and remove that person. Or, if anyone should try violence...."

Rick smiled. "How good do you think they would be against a sniper with a rifle five hundred yards away?"

"Obviously, they would be ineffective."

"Just the point I wanted to make," Rick agreed. "You realize, of course, that there is no protection against a.s.sa.s.sination, except to take refuge in a fortress of some kind and stay there. That's impossible for a public figure like yourself."

"True. Your point, then, is what?"

"That Dr. Briotti has friends with rifles. It would distress us to find that he had been harmed."

"It would distress me," Lazada a.s.sured them. "I was very much impressed by Dr. Briotti's knowledge and enthusiasm. I a.s.sume that you think I have some knowledge about his disappearance. I do not."

"Me either," Nast added hastily.

Lazada's round face glistened with perspiration. "I will control my anger, Mr. Brant. I take your age into account. Allow me to remind you, however, that I am an official of the Philippine Government and that you are an alien. You are here on sufferance, and you have only such rights as you can persuade us to give you. Oh, I know there are agreements. But let us be realistic. Do not force me to lose my temper and do something for which I would be sorry."

"All right." Rick rose. "I'm not as enthusiastic about this expedition as I used to be, but we're going through with it, anyway, starting tomorrow. The sooner we finish, the better for everybody." He looked at Nast. "Except you. I can only promise you that your pal Lazada will never be able to give you the golden skull to smuggle into China."

The boys walked back to their own table and left Nast and Lazada staring after them. That would give them something to chew over, Rick thought.

"I'm not sure that we were smart," Scotty said when they were seated once more. "I'm sure Nast had something to do with Tony's disappearance, but I can't tell you why I'm sure. Was it wise to throw it up to them?"

Rick shrugged. "Maybe not. But it's done now."

The boys slept with locked windows and doors, but they slept soundly.

Down the hall, Angel also regained strength and optimism while he slept, so that the three awoke the next morning with a determination to make some real progress. They had followed their plans and obtained a jeep the night before. But they would need blankets and warmer clothing, unless their supplies could be recovered.

Over breakfast, Scotty estimated their chances. "Suppose we find out that the truck is somewhere in the Ifugao country. Would that guarantee our getting it back? No, it would not. So, we'd better write off the stuff in the truck as lost."

Fortunately, stores open early in Baguio, and the boys were able to buy the things they needed. Scotty also bought an extra five-gallon gasoline can for the jeep. Then Angel and Scotty loaded their few belongings into the vehicle, shook Rick's hand, and headed for Bontoc.

They had agreed that it might be convenient to have the Sky Wagon at Bontoc, too, so Rick would fly up later, planning to arrive at about the same time. Now, he sat down in the hotel lobby and penned a note to the American amba.s.sador, describing the events of yesterday and telling of their future plans. He gave the note to the desk clerk, with instructions that it was not to be sent for three days.

Rick figured that at the end of that time he would either reclaim the note, or that all of them would be in need of help, and the American amba.s.sador would get the letter and use it as a reason for sending a strong note to the Philippine Government, or maybe call out the Marines, the Navy, and the Air Force. Rick was a little vague on just what would happen.

The note written, he tried to read for a while. Scotty and Angel were not well started, and it would be pointless for him to go on to Bontoc alone. He wondered where Chahda was, and what he was doing. The Hindu boy had his own way of operating, and it was one Rick and Scotty could not hope to copy. Chahda had the gift of mimicry. He could fade into a new background as though he belonged to it.

Rick hoped that Chahda, somehow, was keeping a protective eye on Tony.

He couldn't read. He tried napping, but that was no good, either. At last, unable to remain idle a moment longer, he took a taxi to the airport, topped off the Sky Wagon's tanks with gas, checked the plane thoroughly, got a weather report and took off.

He climbed to fifteen thousand feet and scanned the terrain for landmarks. He spotted Mount Panay to the west, verifying its name on the map. Then he picked up the Bontoc Road and searched for the highest point, where it emerged from the valleys and swung across a peak over seven thousand feet above sea level.

If he had estimated Scotty's travel time correctly, the jeep should just now be emerging into the brilliant sunlight of the peaks. He wished for binoculars, but they had failed to bring any, one of those oversights that happen on any expedition.

There was a little traffic on the road. A car of some kind was at the peak, probably stopped to allow the occupants to see the magnificent view. Then he saw that the car was being driven off the road into a grove of trees just beyond the peak. That was odd.

He identified the jeep. In a moment or two it would be at the peak. He would go down and wave. Then he would go back to the airport, have lunch, and fly on to Bontoc. That way, he would get there only slightly ahead of Scotty and Angel.

He lost alt.i.tude. Below, men were getting out of the car which had driven into the scant cover of a scrub-pine grove. Rick watched as they walked to the peak. Sunlight reflected from metal. Probably lunch boxes, he thought. The men were going to have their picnic lunch while looking over the wonderful mountains of northern Luzon. Good idea. Probably that was why they had parked the car off the road.

Then he saw that they were not stopping at the peak, but were taking positions along the road a short distance beyond it. Again, sunlight glinted from metal as one of them sat down in a copse just off the road.

Sweat suddenly poured on Rick's forehead. He wasn't watching simple picnickers! He was watching an ambush being set up--and it could only be for one vehicle, because there was only one in sight along the miles of twisting highway.

Scotty and Angel!

Rick spun the Sky Wagon up on a wing and let it slide. He held the slide for long moments while the altimeter ticked off the lost alt.i.tude. Not until it registered eight thousand feet did he level off, only a thousand feet above the mountaintops. For a moment he couldn't see Scotty and Angel, then he saw them climbing toward the peak at a good speed. In about twenty seconds they would reach it.

He gauged the amount of clearance he had. It wasn't much. Then he put the stick forward and dove for the road. He leveled off so low that his prop wash kicked up dust. The jeep seemed to rush at him and he had a glimpse of Scotty's surprised face, then he was roaring up in a climb that flattened him against the seat. He leveled off and looked for the jeep. It was still moving ahead.

Rick groaned. Scotty thought he was just playing! He should have written a note and dropped it, but now there was no time. The jeep would be in the ambush before he could let his friends know why he had buzzed them.

He was helpless. There wasn't anything in the Sky Wagon that he could throw at the enemy. But he could at least try to make them keep their heads down. He roared in for the attack, aiming at the places where the attackers waited.

The ambushers had the advantage. All they had to do was sit still. Rick could not hurt them without cracking up the plane and actually landing on them. Still, it was terrifying to have the plane roar past scarcely two feet above one's head, and Rick knew the attackers would be worried about the possibility of an accident.

One man had weak nerves. On Rick's second pa.s.s he stood up and ran, heading for the comforting shelter of the trees. Scotty saw him. The jeep braked to a halt.

Instantly the ambushers opened fire. Scotty and Angel jumped from the exposed jeep and took to the ditch. Rick dove at the riflemen again and saw them shoot at him.

He gained a little alt.i.tude and circled, estimating the situation. There were four attackers, counting the one who had run for the car. That left three effective ones. Scotty and Angel were unarmed, a grave mistake.

They should have purchased weapons. However, since he had been able to warn them, the attack had failed. They were in good cover, and as long as he was overhead, ready to dive on the attackers if they should try for a better position, the two were all right.

Rick thought he saw a way out. At least there was no harm in trying. He took the pad of paper he kept in the door pocket and printed a message to the attackers.

YOU HAVE LOST. NO MATTER WHICH WAY YOU GO, I CAN FOLLOW. I CAN HAVE THE POLICE TRAP YOU AT BONTOC OR BAGUIO. I CAN CARRY POLICE TO BONTOC FASTER THAN YOU CAN DRIVE THERE. BUT IF YOU LEAVE YOUR RIFLES IN THE ROAD, GO TO YOUR CAR, AND HEAD FOR BAGUIO, I WILL DO NOTHING.

He searched for a weight and found his emergency fishing kit, a war surplus item which he carried in case he might someday find himself at a good fishing spot without tackle. From the kit he extracted a heavy sinker. A piece of fishing line completed the rig. He lashed the sinker to the folded paper. Now to toss it out so it would land among the attackers. He swung low over the road, gauging his distance. When he saw the peak rushing at him he released the weighted paper, climbed swiftly, and saw one of the attackers run to get it.

Apparently it made sense to the three men. They talked among themselves for a moment, then carried their rifles to the middle of the road and went to the car. Scotty and Angel realized that something was going on, but prudently remained under cover. Not until the ambushers' car roared past on the way to Baguio did they emerge and wave at Rick. He waggled his wings, then turned and made a beeline for the city. He wanted guns and ammunition, and there was no time like the present to buy them!
