“Peg! Oh, Peg! Come here quick!” she called excitedly in another moment. “I knew I was on the right track. Look!” Again she paced the length of the hall from the door, back. “You see,” she explained, “there’s about eight feet difference in the distance on this side of the wall and that in the kitchen.”
“What do you mean?” asked Peggy in surprise. “It’s bound to be the same.”
“But it isn’t. That’s what I’m trying to tell you. Now, if the wall measures less on this side, wouldn’t you figure there was some reason for it?”
“Why—yes, I suppose so.”
“Well, then! What would you call a space eight feet deep—and with a window in it?”
Peggy stared, wide-eyed. “Why, Jo! You mean—there’s a room back there?”
“Exactly! It couldn’t be anything else,” Jo Ann replied, taking the shade off the light. “Here, hold this light at this angle so it’ll shine on the middle of this wall.”
“Is that right?” asked Peggy, trying to do as she was told.
“No, shine it over a little to your left.” The next moment Jo Ann exclaimed in disgust, “Oh, gee! It’s so dark in this corner, even that doesn’t do much good. Wish I had a light ’way back here.”
“Wait a minute. I’ll get my flashlight,” called Peggy, running quickly to her room.
