"Well, isn't he working hard on it?" Betty wanted to know.
"I thought Will was going to get us clues," Mollie went on. "Or your father?"
"Oh, of course they may find the owners, but they are waiting for something to be published in the papers."
"Well, is Allen doing any more?" Amy asked. "If he is he hasn't said anything to us about it, though of course you'd be the first one to hear of it, Betty," she said, innocently enough.
"I?" cried the Little Captain, with upraised eyebrows. "Why I, pray?"
"Oh, because you and Allen are——"
"That's enough!" laughed Mollie. "Spare her blushes, child!"
"Oh!" exclaimed Amy, in confusion.
"You needn't worry about me," said Betty, quickly. "What I meant was that Allen is working on a plan to solve the mystery."
"Has he told you all about it?" Grace wanted to know.
