For the first time in her life, Linda Carlton was thankful that her father was not at home. He would object to her calling Ted at the hospital, but now it was impossible to ask his permission. Nevertheless, she was trembling when she took off the receiver and gave the hospital's number.

"Mr. Mackay left last night," the attendant told her, "to go to his home. He was very much better."

"Oh!" exclaimed Linda, hopefully. That was good news indeed. But she wanted to learn more.

"Would it be possible for me to talk to his nurse?" she inquired. "I really have something important to ask."

The attendant hesitated; it was not their custom to call nurses from their duties to answer inquiries about their patients. But Linda's voice was so eager that the man decided for once to waive the rule.

"If you will hold the line a minute," he said, "I will see whether she is busy. You don't know which nurse it was?"

"No. Probably one of the ward nurses."

Linda was forced to wait several minutes, but in the end she was rewarded. A cheerful girl's voice informed her that its owner had taken charge of Ted Mackay while he was at the hospital.

"But are you a friend or an enemy of Mr. Mackay, Miss——?" she inquired, cautiously. "Carlton is my name," answered Linda. "And I am a friend."

"I'm glad to hear that. Mr. Mackay is such a nice boy that it is a shame he has to have enemies.... Now, what can I do for you?"

"Tell me what you know of his story," replied Linda. "You see I only know that he was shot and that his enemies are trying to connect him with a thief who stole a valuable necklace. I know it can't be true. It just can't!" She was talking rapidly, excitedly. "I knew if I could see him he could explain everything. But he's gone!"

"Yes, he went home last night. To his mother's. But I can tell you the facts, for he told me the whole story. He was piloting another plane—for his company—and spotted a wreck. It proved to be this thief, who evidently wasn't hurt by the crash, and so shot Mr. Mackay and made off in his new plane. It seems perfectly simple to me. I don't see how anybody could possibly accuse Mr. Mackay, when he was actually wounded himself."

"How does his company feel about it?" asked Linda.

"Same as we do. He is to go back to his job in a day or two, as soon as he feels rested."

"Thank goodness!" cried Linda. "Then everything is O.K. Oh, you can't know how thankful I am! And so grateful to you!"

"You're entirely welcome," concluded the young nurse, pleased to have been of some help.

Linda began to sing as she replaced the receiver, and she went out on the porch in search of her aunt. She just had to tell somebody about Ted's innocence, and the weight which had been taken from her heart at the nurse's reassuring words. Miss Carlton had not heard any particulars about the story; indeed she scarcely knew who Ted Mackay was. So, omitting the parachute jump, Linda began at the beginning and related everything she knew about him, since that day last April when she had met him at the Red Cross Fair, and he had promised to take her up in an airplane.

"And you don't think he's wicked, just because his father is, do you, Aunt Emily?" she asked, anxiously.

"No, of course not, dear. It wouldn't be fair to jump to any such conclusion as that. Every human being has a right to be judged on his own merits—not his parents'."

"That's what I think," agreed Linda. "But Daddy says——"

"Hello, everybody!" interrupted a gay young voice from the hedge in front of the bungalow, and, turning about, Linda saw Ralph Clavering striding up the path.

"Hello!" she answered, trying to make her voice cordial. Such a handsome boy, so charming—why did he have to be so unfair to Ted? Poor Ted, who had never had one-tenth of Ralph's advantages!

"I've got news!" he cried, as he took the steps two at a time, and swung into a chair.

"About the necklace?" demanded Miss Carlton, immediately.

"Yes. From our detectives. They have spotted a gas-station that sold a can of gasoline to a red-headed fellow who said he wanted it for an airplane."

"Really, Ralph!" exclaimed Linda, scornfully. "You don't call that news, do you? There must be plenty of red-haired pilots in our part of the country."

"I know. But that isn't all. This agent carried the gas over in his car to a field where the plane was waiting, and he says there was another chap in it who answered the description of our thief."

"Was the plane a Waco?" questioned Linda, keenly.

"The fellow wasn't sure, but when Greer described it, he thought it was."

"And is that all?" Miss Carlton's tone showed disappointment.

"'Is that all?'" repeated Ralph, in amazement. "Why, that's plenty!"

"I don't see how that will help you to catch your thief," remarked the woman.

"But it will! Greer has telephoned the hospital, and located Mackay today. If he really has gone home, as he said, and hasn't run away, he'll be put through a third degree that'll make him tell where the thief is hiding. Because he must be hiding. He couldn't go very far on the gas in that plane, and all the airports and gasoline stations have been warned to watch out for him."

Linda's eyes were blazing with anger. How could Ralph be so prejudiced, so cruel?

"But Ted doesn't know any more about that thief than we do!" she protested, vehemently. "I talked with his nurse this morning—and she knew all about it. Ted met that thief by accident!"

"By accident is right," remarked Ralph, with a scornful smile. "But never mind, Linda—don't you worry about it any more. Let's talk about the masque ball tonight. You're going with me, aren't you?"

"I certainly am not!" announced the girl, haughtily. "I wouldn't go with anybody who could be so unfair——".

"Children!" interrupted Miss Carlton, distressed at their inclination to quarrel. She had been so happy about the friendship between Ralph and Linda—it was eminently right! When her niece did decide to get married—though she hoped such an event was still far off—she couldn't imagine any young man who would suit her so well as Ralph Clavering. Such family! Such social position! And plenty of money! For Miss Carlton was always afraid that sometime her brother might lose his. He was so careless about it, he spent it so recklessly upon both his sister and his daughter. And, though the older woman had enough of her own securely invested in bonds to take care of her old age, she feared for Linda. Educated as she had been at that expensive private school, she was in no way trained to earn a living. She did not dream that Linda would be only too delighted to go into aviation as if she were a boy on her own responsibility—like Ted Mackay!

"If I admit I'm jealous of Redhead, and say I'm sorry," conceded Ralph, "will you forgive me and go to the dance with me tonight?"

His beautiful dark eyes were pleading, and for a moment Linda almost weakened, thinking of all their experiences together, and especially that moment when they both had thought they were so happy, in regaining the box that supposedly held the necklace. But she remembered Ted, and the cruel gruelling he would be subjected to very soon, because of Ralph's suspicions, and she closed her lips tightly.

"Not unless you promise to call off your detectives from Ted Mackay," she pronounced, firmly.

"But I can't do that—couldn't now, even if I wanted to. It's too late."

"Then I'm not going to the party with you."

"But Linda, dear," put in Miss Carlton, going towards the screen door in her embarrassment at being a witness to the quarrel, "it's too late to arrange to go with anybody else. All the other girls already have their partners!"

"I'll go with you, Auntie!" replied the girl, complacently. "Lots of girls go with their parents."

"Very well," agreed her aunt, disappearing into the living-room, with the unpleasant thought that it was only the unpopular girls who were forced into such a situation.

As soon as she had gone, Ralph came over to Linda's chair. But he was afraid to touch even her hand—she looked so aloof and determined.

"Linda—after all we've been to each other——" he began.

She stood up, holding her head high.

"I think you'll have to excuse me, Ralph," she said. "I'm very busy."

"All right," he returned, sullenly. "Have it your own way, then! I'll get Louise to go with me."

"Very well. Good-by." Her tone was icy; she did not even offer to shake hands with him.

Ralph turned and hurried down the steps, angry at himself for pleading so hard, angrier at her for being so cold. No girl ever thought of treating him—Ralph Clavering—like that before! The very idea! Most young ladies would be only too delighted at his invitation! And all for the sake of a penniless, dishonest, red-headed pilot! For Ralph had not yet learned that there were some things which he could not buy with his father's millions.

So he strode to the nearest telephone booth, and called Louise Haydock who, although she was flattered by the invitation, did not immediately accept. She had already promised Harriman Smith, and she so informed Ralph.

"Well, there isn't any law that says a girl can't go with two men, is there?" he demanded. "If she happens to be popular enough! Can't we all three go together?"

"Why aren't you going with Linda?" inquired Louise, shrewdly.

"We've quarreled," he admitted.

"Then make it up!" she advised. "Pull yourself together, Ralph—and apologize."

"I tried to, but it was no good. No, we're off!"

"Then Linda hasn't any partner?"

"She says she's going with her aunt," muttered Ralph.

"Oh, that won't do!" exclaimed Louise. "Wait, Ralph, I'll fix everything. I'll get Harry to take Linda—he's crazy about her anyhow—and then I'll go with you."

"O.K., Lou. You're the little sport!"

"And fixer," added the girl, to herself, as she bade Ralph good-by, and called first Harry and then Miss Carlton.

Louise's suggestion seemed like an act of Providence to the older woman; it would have been mortifying indeed to her to have Linda appear at the ball without a masculine escort, as if the girl were a mere wallflower. Harriman Smith had been most agreeable about the whole arrangement; anything Louise decided suited him, he told her. And Linda, too, was delighted with the news.

She came out of her bedroom while her aunt was talking on the telephone, dressed in her flyer's suit.

"Where are you going dear?" inquired Miss Carlton, in anxious surprise.

"I'm going scouting," explained Linda. "I think I'll fly around—pretty low—and look for wrecks. I have a hunch that that thief has smashed his plane by now. He was such a poor pilot, you know I told you."

"Well, be careful," cautioned her aunt. "But so long as you fly low, I won't worry."

Linda smiled to herself. If Aunt Emily only realized how infinitely more dangerous it was to fly low than high!

She found her Pursuit in perfect condition, and had it taken to the runway, where she taxied off without the least difficulty. She climbed to about fifteen hundred feet, and flew over past the hospital and the field where the Waco had been smashed. Then she carefully came lower, using her glasses to watch the ground as she flew.

The country was open—there were no buildings and few trees, so she felt safe in keeping within sight of the ground. She was flying along confidently, when suddenly a long pole seemed almost on top of her. Swerving sharply upward, she just avoided striking some wires that the pole was supporting.

"Oh!" she gasped. "What a lucky break! Suppose I hadn't had a foolproof plane!" For she knew that her Arrow had been designed especially for amateurs like herself.

"Crazy of me to fly so near to the ground!" she exclaimed, in self-contempt. "After all the warnings I've had! I deserve a crash!" And she continued to climb upward to safety.

As she flew onward, steadying her thoughts, she decided that it was senseless to try to hunt the thief with a plane. If she wanted to look for him it would be much more reasonable to use her car—or to hike. So she abandoned that project entirely.

But as she continued her flight towards Green Falls, it suddenly occurred to her that she might help Ted in another way. She could establish his alibi for him—by means of his company! That red-haired man that the agent claimed he saw with the thief couldn't have been Ted, and she would take means of proving it. Then, if Ralph's detectives insisted upon throwing him into prison, there would be a way to have him released.

So she flew back to the airport, confident that her morning had not been entirely wasted, and, to her aunt's relief, she arrived home in time for lunch.
