"Where is your mother?" she asked, immediately, for there was no sign of a hostess inside.
"She is ill," replied the young man. "The bad news about the bank – a great deal of our money was lost – knocked her terribly. She hasn't told grandmother, or it might kill her. So I had the maid get the guest room ready, and hope that you will excuse them both."
Linda nodded; she had no way of knowing that Mrs. Carter had protested about entertaining this girl whom Jackson had "picked up" on his canoe trip, and had stubbornly refused to see her. The woman had worked herself into such a state of nerves over her losses and over this incident that she had actually made herself ill.
"I'm so sorry," said Linda, sympathetically. "If I weren't so tired, I'd go to a hotel, for this is no time for your mother to be bothered with a guest. But I'll just stay tonight, and leave early tomorrow. I'm flying to the swamp again with the police officers."
"Ann!" cried Jackson aghast, using her name unconsciously. "Don't, please! It's dangerous – you may be killed… And, and, besides – "
"Besides, what?"
"Besides, it isn't done. You shouldn't go off to lonely places like that, without an older woman along."
Linda smiled.
"I can't be bothered with social codes at a time like this," she said. "I have to do all I can to get that money back. Think of the hundreds of people hurt by that bank robbery – if the bank is forced to close its doors! Including your own mother and grandmother! No, I just have to go."
"Let me go instead," he suggested.
"You wouldn't know just where the camp is. It's pretty well hidden, and I know the only spot where a landing is possible. Besides, you can't fly a plane."
"You mean you will pilot the plane yourself? Your autogiro's broken."
"Oh, it'll be another plane – a hired one. Now please don't argue any more, Mr. Carter – you sound like my aunt – and let me go to bed. And will you ask one of the servants to waken me at seven o'clock?"
"Good night, then, Miss Carlton," he said, almost sorrowfully, for it seemed like the end of what might have been a wonderful friendship for Jackson Carter.
Chapter IX
Two Prisoners
Linda's telephone call came early the following morning, and after a simple breakfast served by the cook, she left in the car which Captain Magee sent. Not one of the Carter family appeared at the meal, and there was no message of any kind. Linda, however, attributed this to Mrs. Carter's illness, and wrote a polite note of thanks to her hostess.
She found three plain-clothes men waiting for her at the police station, and they joined her in the car which then took them to the airport. A large cabin plane, capable of accommodating six persons, had been wheeled out on the runway, awaiting their arrival and two service men were standing beside it.
"You are sure you can pilot her, Miss?" inquired one of these men, skeptically.
Linda opened her bag and took out her two licenses – mechanic's and transport pilot's – and handed them to him.
"A mechanic!" he exclaimed, in amazement. "Gee whiz! Will wonders never cease? It's the first time I ever laid eyes on a lady-mechanic!"
Linda laughed.
"May I look the plane over before we start?" she asked. "And will you map out the quickest course to Okefenokee Swamp! I want to get into the southern part of it – Black Jack Island, if you know where that is."
With a grin the man disappeared to consult some one in the hangar, and Linda went ahead with the examination.
"There ought to be plenty of room in here to bring back any prisoners we may get," she said, cheerfully. "I think too, that you had better send for some food and water, Sergeant – for we can't tell how long we may be gone."
When she announced herself satisfied with the inspection, she and her three companions climbed into the cabin while the mechanic fired the engine. The plane taxied along the runway and rose gracefully into the air, to the admiration of the three officers, none of whom could fly.
"You're there with the goods, Miss Carlton!" shouted the one named "Worth," who apparently was in charge of the expedition.
"Don't praise me too soon," returned Linda. "That was child's play. But wait till it comes to landing on that island in the swamp. There is only one spot big enough, in a plane like this."
"Well, we got plenty of gas," remarked Worth, cheerfully. "I'm not afraid. I'm enjoying the flight. It isn't every day that we go up in the skies on our job."
Linda was enjoying it, too. She flew carefully, watching her map, her instruments, and the landscape below. They flew over the island where they had left Susie, and Linda made a mental note of the location, in case she should be able to pick the girl up on the return trip.
It was difficult to keep her direction, for the swamp, covered as it was with grasses and trees, seemed like an unbroken, monotonous expanse from the air, but Linda had succeeded in spotting the little stream down which the boys had paddled the canoe, and she resolved to follow that to the place where they had picked her up. After that it ought to be easy to locate Black Jack Island and the camp of the thieves.
But it was not as simple as she had hoped, even after she had located the island. Again and again she circled about, looking for a space large enough to make a landing. Finally she found what must be the edge of the island, for the water came up unevenly, but this beach appeared very small. It was one thing to bring the autogiro safely to earth in a place like this, and another to land a big plane.
When she had selected her spot, she determined to try "fish-tailing." She glided with considerable speed toward her field; as she approached it, she swung her airplane from side to side, exposing the flat side of the plane's body to the air so as to kill the speed.
Her companions, who had no idea what she was doing, looked at Linda in alarm. Had she lost control of the plane, and were they about to be dashed to pieces?
But a glance at their pilot's calm, confident expression allayed their fears. This girl knew what she was doing! They need not be afraid.
Often at the ground school she had been compelled to land on a given spot – such as a square of canvas; it was no wonder that she now felt sure of herself. A moment later she came down on the very mark that she had selected.
"Pretty neat!" exclaimed Worth, in admiration.
Linda turned off the engine and prepared to get out of the plane. But the Sergeant stopped her.
"You stay in here, Miss Carlton!" he ordered. "This is no place for a girl."
"But I have to show you where the camp is," she protested.
"Then show us from here! And remember, too, that you are our pilot. If anything happened to you, we couldn't get out of this swamp."
Linda saw the reasoning in this last argument, and agreed to remain inside of the cabin until she should be summoned. She sat there tensely, while the three men advanced cautiously towards the trees at the center of the island.
They had not gone more than a dozen yards when a shot rang out from behind a tree, and a bullet whizzed past over their heads. A cry burst from Linda's lips, then an exclamation of relief at the assurance that her companions were unhurt.
"So they're still here!" she thought, excitedly, clasping her hands so tightly together that they grew numb with the pressure. "Oh, if the men only get them without being shot!"
The officers' pistols replied rapidly to the shot from the thieves, in such quick succession that Linda could almost imagine that she was in an actual war zone. But the volley lasted only a moment, for the thieves were short of bullets since "Slats'" disappearance, and before anyone was hurt, "Beefy" and "Jake" surrendered to Sergeant Worth.
Watching the whole proceeding from the window of the plane, Linda drew a deep sigh of relief. Then suddenly she remembered the third member of the gang – the man nick-named "Doc." Where was he? Hiding in the background, waiting to shoot them all down when they were off guard?
Cautiously, therefore, Linda leaned out of the side of the plane and called to Sergeant Worth to come back to her. Leaving the two thieves in charge of the other men, who instantly handcuffed them, Worth returned to the airplane, smiling over his easy victory.
With his assistance Linda jumped out of the cabin and whispered her warning into his ear. The man scowled in disappointment.
"This fellow may be waiting for you, Miss Carlton," he said. "You stay right here – behind the plane, while I go find out where he is."
Linda did as she was told, expecting every moment to hear renewed shooting.
