“It’s Adelia⁠—and she has a big flashlight,” came, a moment later, from Frank. “What do you know about that!”

“She’s looking for the treasure herself!” cried Joe. “Huh! And after all she said about our looking being nothing but foolishness!”

They saw the woman gaze out of the window for a few seconds. In one hand she held the flashlight. For a moment she turned the light into her own face, and the boys saw there a look of utter disgust.

“Didn’t find it, I’ll bet a cookie!” chuckled Joe.

“Come on⁠—let’s get away before she spots us,” returned his brother, and they were soon on their way.

As they walked home, Joe and Frank talked the matter over. They smiled when they thought of the eccentric woman up in that dusty old tower, but their minds soon went back to Slim and the troubles of the Robinson family.
