"The funny thing was that they never took anything of value," Fred added. "Most of our belongings were tin——"
"Except our bathing suits, of course," broke in Frank, with a grin. "But even they were sort of moth-eaten and uninviting. Nothing to tempt a thief, you'd say!"
After they returned to the Hall the girls thought a great deal about this new turn of events.
"Stealing bathing suits and things," Jo repeated dreamily. "Sounds sort of familiar, doesn't it? Like the theft of gym and bathing suits from the gym and the boathouse?"
"You mean it looks as though the same thief robbed both places?" Sadie asked, and Jo nodded.

There was a slight sound behind her, and she started and turned swiftly.
