“Let’s go into Dad’s office and out on his balcony so we can watch for her,” suggested Florence a moment later. “She’ll surely be back in a few minutes.”
“I’m going to give her a piece of my mind,” fumed Peggy. “She ought to know better than to go off that way. Something might happen to her.”
Looking in every direction, the girls were dismayed at seeing no signs of Jo Ann.
“She seems to have disappeared in thin air,” said Peggy anxiously. “Something must be wrong. She wouldn’t stay away this long.”
Almost simultaneously Florence turned her head, listening. “What was that? Didn’t you hear someone whistle?”
The next moment a faint but distinct whistling note sounded.
“That’s Jo’s whistle,” exclaimed Peggy. “But where is she?”
“Here I am!” called a low voice. “Up on the roof.”
“What!” The girls gasped in amazement.
Blankly they stared above them as a red, flushed face, framed with tousled hair, peeped over the edge of the roof.
