"Children," interrupted Miss Carlton, who had been patiently waiting to serve the refreshments, "wouldn't you all feel better if you ate something? Then we can discuss what are the best steps to take to capture the thief."

They agreed, but Linda and Ralph and Kitty were all extremely nervous; they hated to lose any time. Ralph decided to telephone to a lawyer at once in Spring City, to put expert detectives on the job, and to get in touch with the Flying School.

"Lucky the necklace was insured," remarked Maurice Stetson, as he drank his ginger-ale.

"Yes, but Dad will never get me another!" moaned Kitty, disconsolately. "He'll say I was careless, and invest the insurance in bonds, to be kept in trust till I'm older—or something like that." She started to cry afresh. "And I only wore the necklace twice—at graduation and at the class dance!"

Linda watched her sorrow with more than sympathy—with remorse. It was her fault, she was sure! Of course she couldn't imagine caring so much for a pearl necklace, when such lovely imitations were made, but it wasn't her place to judge. Kitty probably wouldn't understand why she loved her Arrow so much.

Slowly, painfully, she came to her decision. She rose and went over to the couch where Kitty was sitting, and crowded in between the latter and Dot.

"It's my fault, Kit," she said, "and of course I can't pay for it—but I can help. I'm—I'm—going to sell my airplane, and—give you the money. Then you can start buying a new one—a couple of pearls at a time."

Kitty squeezed her hand affectionately.

"You're a dear, Linda, but I couldn't possibly let you do that. Besides, it was really Ralph's fault."

"Of course it was!" put in the young man, returning from making his telephone call. "But we're going to catch that thief!" he announced, with conviction. "I've just been talking with Lieutenant Kingsberry at the field, and he says that fellow didn't even have a license, that they only took him on temporarily, as sort of errand boy. And he deliberately stole that plane!"
