“Certainly, child,” Miss Sallie replied, her serenity undisturbed. “It is true your father may not have returned from his fishing trip, but there is no reason why we should not go without him.”

Ruth closed her eyes. Could it be possible that they might be invited to eat food paid for by money gained dishonestly? Surely Monsieur Duval could not have spoken the truth!

“Here comes that Mrs. De Lancey Smythe,” remarked Miss Sallie with sudden energy. “I do wish that woman would keep away from us.”

“Aunt Sallie,” said Ruth, “what do you dislike most about Mrs. De Lancey Smythe?”

“Don’t ask me, my dear,” returned Miss Stuart rather impatiently. “Everything I should say. I must confess that the very sight of her irritates me.”

“There is something peculiar about her, at any rate,” said Ruth, “I have seen her face grow hard as rock and look positively wicked when she thought no one was noticing her. Marian is afraid of her, too.”

“Nonsense, Ruth,” replied Miss Sallie severely. “You and Barbara let your imaginations have too free rein. I don’t approve of the woman and dislike her intensely, but I am not going to make her out an ogre.”

“She is, though,” persisted Ruth. “That’s why you don’t like her, only you don’t know it yourself. Some day you’ll see I am right. Oh, here come Mollie and Grace. What’s new, chilluns?” and springing to her feet Ruth called to Bab then hurried toward the approaching girls.

Mollie and Grace had been out in a boat all morning with some new friends they had made at the hotel. As Ruth walked toward them she noticed that Mollie’s cheeks were very red, and that she wore a look of suppressed excitement. Grace seemed almost equally agitated. Before she could reach them, however, she was hailed by a crowd of young people who were strolling on the beach, and she and Bab were obliged to stop and hold conversation.

Mollie felt that it was imperative to summon Bab and Ruth. How could she manage without being observed? A sudden thought came to her. Putting her hand back to her curls she hastily untied the ribbon that bound them. The ribbon was blue. In an instant Mollie twisted it into a bow knot and pinned it on her left shoulder. Would Barbara and Ruth remember what the secret signal meant?
