“Then why do they build their houses so high?” asked Peggy.

“It makes them cool,” Florence answered as the car turned off the narrow street onto the pavement around the Plaza.

“Why, we’re almost home!” exclaimed Jo Ann in surprise. “Is it possible that this is part of your house?”

“Not exactly, but it’s all connected into one long building,” she replied, wondering at Jo Ann’s interest.

“Oh, then that’s the very thing!” Jo Ann cried, beaming.

“Whatever are you talking about, Jo?” asked Peggy.

“Why, how to get up on top of the house, of course! Don’t you see—I can climb up that scaffold to the top of the house; then it’ll be easy to let a rope down to the mysterious window. I’ve been wondering how I’d ever get on top of the house—it’s so high.”

“But, Jo, you can’t do that!” gasped Florence in alarm. “It’s too high, and anyway——”

“You’re not going to do it,” declared Peggy emphatically. “You might get hurt.”

“Don’t be silly,” scoffed Jo Ann. “I haven’t broken my neck yet.”
