“Some one I know very well,” replied the lifeguard. “I can’t convince myself that my suspicion could be true. And yet, Mrs. Allison’s remark about the black trunks and brown sweat shirt set me to thinking. Many bathers wear black trunks. But I know of only one hereabouts who has a brown sweat shirt.”

“Who is he?” demanded Vevi, fairly overcome by curiosity.

Barney however, would not mention a name.

“I’m not sure that I have the right slant on the situation,” he replied. “It would be unfair and unwise to accuse anyone without absolute proof. What I must do is keep closer watch than ever of this beach.”

“The thief may over-step himself,” remarked Miss Gordon.

“The Brownies will help you watch the beach,” eagerly offered Vevi. “Jamie will too, won’t you?”

Now Barney Fulsom had forgotten that the little boy was standing close by. He turned quickly toward him as did all the Brownies. Everyone was surprised to see that the youngster appeared very disturbed.

“You’ll help, won’t you, Jamie?” Vevi repeated her question.

The boy stared at her a moment as if he had not heard.

“I—I won’t be here much longer,” he mumbled at last. “I’m going to run away. I’ve made up my mind!”
