“Oh, thank you, Miss Carlton!” he answered gratefully. “It—you—make me feel so at home, and I’ve been kinda homesick in Grand Rapids. And—would you call me ‘Mike,’ please?”

“Certainly, Mike,” agreed his hostess.

“And I’ll see that you get the story of our treasure hunt for your paper,” added Linda, generously. “A treasure hunt by airplane.”

“Gee Whitakers!” cried the boy, enthusiastically. “That is something new!”

Miss Carlton frowned, but said nothing. Amy, too, was silent. She could not be hopeful like the others of hearing from her parents, for she felt sure that there were no parents to hear from.

The telephone rang, and Linda jumped up eagerly, hoping that it meant good news for Amy. To her amazement she heard the fascinating voice of Lord Dudley at the other end of the wire.

“Good morning, Great Aviatrix!” he said. “This is one of your many admirers—Claude Dudley.”

Linda flushed; this was going to be more exciting than news of Amy’s family.

“Good morning, Lord Dudley,” she replied.

“I am going to ask you a big favor, Miss Carlton,” he said. “I have to get back to Chicago to-day, and I was wondering whether you would take me across Lake Michigan in your autogiro. We could lunch at the Lakeside Inn—a place that I know to be particularly charming.”
