When Ted Mackay opened his eyes at the hospital the following morning, he did not know where he was. Although he had regained consciousness when the orderlies brought him in from the ambulance the day before, it had not lasted long. An anesthetic was immediately administered, for it was necessary to cut into his arm, and later a drug was given to make him sleep. So, for the moment, he could not understand why he was here—in a ward, undoubtedly, judging from the long row of cots against the wall.

A dull aching pain in his arm and shoulder made him glance suspiciously at his left side. They were bandaged, of course. And then suddenly he remembered.

He had been sent out with a new plane, from his company in Kansas City, to make delivery to a purchaser in Buffalo. Just before he left, a radio message had been received from the Spring City Flying School, asking all pilots and mechanics to look out for a stolen Waco. Naturally, Ted remembered the plane.

He had been flying quite low, to make certain tests with the plane he was delivering, over the fields beyond Green Falls, when he suddenly noticed a wreck. Complying with the regulations of the Department of Commerce, he descended in order to report the casualty and to render assistance, if possible. Smashed as it was, he recognized it immediately as the old Waco, which he had so often piloted at Spring City. He looked about for the pilot, dreading to find his shattered body in the cockpit.

He had been leaning over, peering into the bushes, when a gun went off at his back, hitting him on the left arm, near the shoulder. Reeling about sharply, he just had time to see a shabbily dressed man run for the new plane. And then everything went black; he couldn't recall what happened, or how he got to the hospital.

"The company's new plane!" he suddenly exclaimed aloud, attempting to sit up in his cot. "It's gone!"

He looked about helplessly for the nurse, for anybody, to verify his fears. But nobody came, although down the hall he could hear footsteps of people busy on their early morning duties.

Warned by the pain in his shoulder, he sank back on his pillow to wait, and as he lay there quietly, he went back over the events of the past week that had been so eventful for him. He thought of Linda Carlton, of the pride and joy in her beautiful eyes when she had won her license. And of her farewell! A farewell that might easily be forever! Yet through no fault of his own, merely because his father had disgraced himself.

It had always been like that with Ted; it seemed as if his father had tried to spoil his whole life. Just when the boy was ready to enter High School, Mr. Mackay had been dismissed from his job for stealing from the cash-drawer of the store where he was employed. The judge had let him off, for he knew what a splendid woman Mrs. Mackay was, and Ted and his older sister had gone to work to pay the debt. It was hard sledding after that; Mr. Mackay wandered off, working now in one place and now in another, and Ted put off his hopes of study for a while. Then, just as the family were getting ahead, and Ted had started in at an aviation school, the man came back for more money. The last they heard of him was a year ago, when he had written that he had a real job on a ranch in Texas. But evidently he had done something wrong there, or Mr. Carlton would not be so bitter against his son.

Ted's shoulder was hurting him badly, and his thoughts were not pleasant, so he uttered a weary sigh.

"Well! Well!" exclaimed a cheery voice at the door. "Is the world as sad as all that?"

Ted's mouth relaxed into a smile, the smile that had won him so many friends at the Spring City Flying School. He had not heard the nurse, a pretty probationer, who just entered the ward.

"How's the shoulder this morning?" she asked him brightly. "You're looking better, Mr. Mackay."

"I'm all right," replied Ted, wondering how she knew his name. "But can you give me any news of my plane?"

"Your plane was wrecked, wasn't it?" she inquired.

"No—I hope not! That was the other fellow's plane. The fellow that shot me."

"Oh, I see. Then there were two planes?"

"Certainly. Didn't you know?... You seem to know my name——"

"There were some letters in your pocket—don't you remember? And the address of a company in Kansas City.... But I don't think anybody realizes that there were two planes—that you didn't wreck yours."

"Oh, but I wouldn't wreck a plane in that way!" he protested. "I think too much of them!" His face lighted up with the enthusiasm he always showed when he talked about flying. "But I've got to get to a telephone!" he added. "I must notify my company immediately of the loss."

"Probably your company knows all about it," she replied. "Anyway, you can't do anything now—except lie still while I take your temperature. And then eat your breakfast. After your wound is dressed—if the doctor agrees——"

"But I've got to get dressed right away! I want to notify them so that they can catch that bandit!"

"Yes, yes. In due time. You must be patient."

"You say they didn't know about that other fellow!" he cried, excitedly. "I tell you——"

He stopped suddenly, for he saw that his nurse had gone off to another cot. There was no use trying to argue with nurses, he learned, for they had to follow the rules laid down by the doctors and the hospital authorities.

So, for the next two hours he did exactly as he was told, not even making an attempt to dress. For his nurse had informed him that he must stay there at least another day.

He was dozing when a representative from his company called to see him. But the man urged the nurse not to disturb him, saying that he would come again the following morning. She told him what she knew of Ted's story, and of his anxiety over the stolen plane, and he promised to send out scouts in its pursuit.

Ted's next two visitors were not so thoughtful of his welfare. Mr. Carlton and Ralph Clavering, who made the trip unknown to Linda, arrived about eleven o'clock, and asked that the young man be awakened at once.

"I think you had better come back tomorrow, if you want to talk to Mr. Mackay," said the nurse, noticing that the two men were not any too friendly towards her patient, for they had not even inquired how he was. "He mustn't be disturbed."

"Then we'll wait until he wakes up," replied Mr. Carlton, firmly. "It's very important that we speak with him as soon as possible."

"You're from his company?" she asked.

"No, we're not."

"Just friends?"

"No."

"Then may I ask what reason you have for wishing to see Mr. Mackay at this particular time?"

"Business. Very important business. We think he is involved in the theft of a very expensive necklace."

"No!" cried the nurse, aghast. It couldn't be true! Why, she had never seen anybody with franker eyes or a more truthful, honest face than this young man with the wounded arm! There must be some mistake.

"Did he act as if he wanted to get out of the hospital as quickly as possible?" asked Ralph, shrewdly.

"Why, yes—but that was only natural. All men, especially young men, are impatient about staying here. Only last week, the day after a man was operated on for appendicitis, he said he had to get back to his office—he just had to! You should have heard him rave. We laughed at him."

"Well, we'll sit down here in the reception room and read the magazines," announced Mr. Carlton. "And you send us word when he wakes up."

There was nothing further she could do, but somehow she was against them. Already she was on Ted's side. She didn't believe he was one of those wicked gangsters you read about in the papers. Why, he was only a boy! A boy tremendously interested in aviation. She could see his eyes shine when he talked about flying, and the absolute tragedy he believed it to be because, a fine plane had been wrecked. It seemed worse to him than being shot. Poor fellow! He would get well, of course, but was this going to cripple him so he wouldn't be able to fly?

About twelve o'clock, when it was time for the lunch trays to be brought in, he awakened. But the nurse had no intention of informing those two men in the waiting-room.

However, they did not wait to be informed. Perhaps Mr. Carlton suspected that the nurse was against him, or perhaps it was merely that he knew that he hadn't much longer to stay—it was imperative that he return to his ranch that night. Anyway, he and Ralph strolled down the hall and found Ted eating his lunch. They walked right into the ward without asking the nurse's permission.

"How d'do, Mackay," said Mr. Carlton, briefly. "How's your wound?"

"Better, thank you, sir," replied Ted, smiling. He had recognized Linda's father instantly, and a feeling of joy surged through him. What a decent thing for the man to do! Probably Linda had heard of his accident, and asked him to come to inquire for him. Of course he was totally unaware of the loss of the pearls; he had no idea that the thief who had taken the two planes had done so for the sole purpose of stealing a necklace.

Remembering Ralph, too, he managed to smile at him also.

"You certainly managed to wreck your plane," remarked Mr. Carlton, not knowing exactly how to begin. "You're in luck that you weren't killed!"

"I didn't wreck my plane, sir," corrected Ted, quietly. "It was the fellow who shot me that wrecked his—or rather the school's, for he had stolen it from the Spring City Flying School, you know. Then he shot at me, and flew off in my plane."

"Oh, is that so?" Mr. Carlton, raised his brows, and his eyes narrowed. He didn't believe a word of it.

"And—er—how did you and this thief happen to be together?" he inquired.

"I was taking a new plane to Buffalo, and flying low, making some tests, when I spotted the wreck. So I brought mine down."

"You knew, then, that he had stolen Miss Clavering's pearls?"

"What?" cried Ted, starting upright in bed, and then, shocked by the pain from his sudden movement, dropping back to his pillow.

"You never heard of a valuable pearl necklace that this young man was carrying from Spring City to his sister, by my daughter's plane?" persisted Mr. Carlton. His tone was mocking, insulting.

"On my honor, Mr. Carlton——"

"Come now, Mackay," interrupted Ralph. "Why not make a clean breast of it? We know you—or this other fellow—heard Linda and me discussing it at the field, and we know you used him as an accomplice. We saw him hanging around outside——"

"You are making a big mistake, Mackay," put in Mr. Carlton, "if you don't confess everything now. I'd be willing to give you another chance—if you tell us how you can get a hold of that fellow, and get the necklace back. I know you weren't brought up right—it's not exactly your fault if you don't know right from wrong——"

But this was too much for Ted to bear. The man was insulting his mother! If he hadn't been Linda's father, Ted would have struck him, crippled though he was. Instead, overpowered by nervous exhaustion, he let out a terrific scream that at least stopped the abuse.

"I do know right from wrong!" he cried. "My mother is the finest woman that ever lived, and she knew what to teach her children! What you say is a lie!"

By this time everybody in the ward was looking and listening in breathless interest, and the head nurse, attracted by the noise, stopped in the corridor.

"You men will leave at once," she commanded, from the doorway, and Mr. Carlton, who was so used to giving orders to others, found that for once he had to obey. He and Ralph picked up their hats and were gone without another word.

After that, Ted was quite ill. His temperature went up, and he became delirious. The little nurse was both angry and remorseful. It was her fault, she thought, for not keeping those dreadful men out. Accusing an innocent boy like her patient!

The visitors, however, went away dismayed. They hadn't proved a thing.

"Unfortunately I have to leave tonight right after dinner," said Mr. Carlton, as Ralph drove him back to his sister's. "I guess we'll have to turn the whole thing over to the detectives."

"Well, we'll see what Greer and his men can do," replied the other. "One good thing, Mackay can't get away from us, crippled as he is. And the other fellow is such a poor pilot that he'll crash sooner or later."

"If he doesn't get out of the country first," muttered Mr. Carlton, dolefully.

"What does Linda think about the affair?" inquired Ralph, for he had not seen the girl since her aunt helped her to go to bed the preceding afternoon.

"I don't know. I haven't seen her. She was still asleep when I left this morning."

"I imagine she believes Mackay guilty. That's what knocked her over so yesterday."

"Well, she'll get over that," returned her father, briefly. And he invited Ralph to come into the house for luncheon.

The young man, however, had the good taste to decline. It would be a ticklish situation at best—and besides, Linda ought to have some time to be alone with her father, if he were leaving so soon.

"But tell Linda I'll be over after dinner," he added. "The bunch is planning a canoe party."
