Chase, his hand on his revolver, climbed out of the autogiro and slipped cautiously around the side. He kept his eyes riveted on the Sky Rocket, but there was no movement whatsoever.

“They’re probably hiding,” he whispered, as the noise of the rotors died out. “You girls stay right here, and creep up on them.”

Dot and Linda did as they were told. In tense silence they watched the young man advance nearer and nearer to the Sky Rocket, expecting every moment to hear a shot ring out from the underbrush that grew along the beach.

It was a deserted spot; there were no cottages or boathouses about. The only sound was the breaking of the waves, with monotonous regularity, upon the shore.

Chase got nearer and nearer; he actually came up to the yellow plane, and peered all around it. Still there was no sign of human life anywhere. He looked into the cockpit; then he sauntered towards the scattered bushes on the beach, examining them with his glasses. And still nothing happened.

Unable to bear the suspense any longer, the girls came out from behind the Ladybug and started to advance towards the Sky Rocket. At the same time Chase, satisfied that the enemy was nowhere about, proceeded slowly back to meet them.

“We’re too late again,” he observed, gloomily. “They’ve abandoned it, there’s no doubt of that. Evidently got scared and decided to leave it.”

Running up to the plane, Linda began to examine it eagerly.

“It seems to be in good condition,” she said. “And that certainly is a lucky break. If I couldn’t get both, I’d rather have the plane than the girl!”

Chase regarded her in amazement.

“But she has your money!” was his comment.

“I know. But I care more about Mr. Eckert’s plane—it’s worth a whole lot more than five thousand dollars. And he was such a good sport to lend it to me. I can just imagine how dreadfully he’d feel, if he thought he’d never see it again. I know how I felt when I lost the Ladybug.”

“But where do you suppose they have gone?” asked Dot. “The Spragues, I mean.”

Linda dropped down to a sitting position on the sand and fished in her pocket for a map.

“They must have taken a boat from somewhere near here,” she said. “So if we can find out where we are, and the nearest seaport town, we might be able to catch them before they sail.”

“We’re pretty far south on this peninsula,” put in Chase, looking over Linda’s shoulder at the map.

“Yes, I think so.... You know what I believe would be best, Bert? If the Sky Rocket is in good condition—we’ll look her over in a minute and find out—one of us could fly her south along the coast, and another take the Ladybug north. In that way we ought to pick up news of our honeymooners pretty quickly.”
171

“Good idea!” returned Chase, immediately. “Which plane do you want, Linda?”

“I think I’d rather have the Sky Rocket,” returned the girl. “If you can manage the Ladybug. Because if I should find out that the Spragues have sailed somewhere in a boat, I might like to pursue them. And the Sky Rocket can go so much faster, and carry enough gas for a trip across the United States.”

“It’s all one to me,” agreed Chase. “If you’ll trust me with the Ladybug.”

“Certainly,” Linda assured him. “Now I think I’ll go look the Sky Rocket over, and tighten some of those wires that I see out of ‘stream-line’. That makes a lot of difference, you know.”

Linda finished her job in less than an hour, and after they had eaten the remainder of their food supply, she gave Chase a few instructions about flying the autogiro. Satisfied that he knew how to manage it, the girls insisted that he take off first, flying back north along the sea-coast.

“And when you’re through, you can park the Ladybug at the Los Angeles airport,” concluded Linda. “I’ll pick her up there, after the girl has been caught—by us, or somebody else.”
172

She and Dot stood watching the young man take off and soar into the air, until he was finally lost to sight. Once again they were alone, but with more hope of success than they had had before. Now both planes had been regained, and they had the Sky Rocket to rely on. They felt, with it, that they had the world—or better still, the air—at their command.

“There must be a seaport pretty near here,” said Linda, as she and Dot climbed into the powerful yellow plane. “If the Spragues haven’t left from there, they at least ought to be able to find out by wire what vessels have left the coast.”

She flew straight down to Cape San Lucas, a seaport town, which boasted of a sizable airport. It was terribly hot here, when she brought the plane to the ground; the heat seemed to rise in waves to hit them in the face as the girls climbed out of the cockpits. For the airport was located behind the town, and that morning no ocean breezes brought cooling refreshment to landward.
173

It was a large airport, and it kept attendants who could speak all the principal languages. The man who came forward, a dark Mexican, surprised the girls by speaking perfect English.

Briefly Linda told him the facts of her story—about the stolen planes, which had since been regained, and the forged check for five thousand dollars. But she said nothing about the part in the talking-picture, or of the girl’s having taken her name. There was no reason, she felt, for emphasizing that point or drawing publicity to herself.

“So we think this couple have sailed,” she concluded. “Though under what name, we don’t know. Probably neither Sprague nor Bower, but something else, to fool us, and throw the police off the track. Our first desire is to find out what big vessels have left this vicinity today or yesterday.”

“I’ll get in touch with the docks immediately,” the man assured her. “Though I think can tell you myself. A vessel named the ‘Mona’ left here yesterday for Hawaii. There isn’t another until day after tomorrow, which sails for South America.”

Linda’s eyes shone with excitement.

“Hawaii!” she exclaimed. “I always did want to fly the Pacific!”
174

“You wouldn’t try it!” he cried, in horror.

“Why not?” she demanded. “It’s only a matter of about two thousand miles—less than a non-stop flight across the United States. And I have a marvellous plane.”

“You mean—this?” he asked, pointing to the Sky Rocket.

“Yes. She’s a marvel, even if she has only one motor. She can make a hundred and fifty miles an hour, and is equipped with all the newest inventions and improvements.”

“I can see that.... But the danger—in any kind of plane,” he remonstrated. “No woman has ever attempted it, and plenty of airmen have found a watery grave in the Pacific.”

“Well, some woman has to be first,” returned Linda. “I’ll think about it, anyway. In the meanwhile, I think I’ll go down to have a talk with the men at the docks.... By the way, have you an expert mechanic?”

“The very best!”

“Then please have him give the Sky Rocket a thorough inspection. Doubly thorough, for tell him what I am contemplating. And have him take a look at the wireless that is already installed. And fill her up with gas and oil.”
175

“O. K.,” agreed the man, shaking his head as if he thought Linda were crazy.

“Oh, yes—and could you get me a rubber life-boat?” she inquired.

“At considerable cost.”

“Well, get me one if you can, and have it put in,” said Linda, as if she were ordering an ice-cream soda.

“Then you really are serious about going?” asked the man, unable to believe she meant what she was saying.

“If I find good reason to think that couple sailed for Hawaii,” she replied. “But not if I don’t. It isn’t a stunt, you see.”

The girls left immediately in a taxicab for the dock. Here they saw numerous small boats and yachts, and it occurred to Linda to wonder whether the missing couple might not have gone off in a pleasure boat. But after all, they couldn’t get far in the Pacific in a yacht, unless it were one specially built for the purpose, and the idea seemed improbable.

They made their inquiries about the couple of a sailor.
176

“Yes, there were several young couples among the passengers that left for Hawaii yesterday,” he informed them. “About thirty passengers, all told.”

“But did one of the young couples look like honeymooners?” demanded Dot.

“Can’t say as I noticed. But you can look at the list of passengers in the office. That ought to tell you.”
