"She's all right," declared Bob confidently. "You see, I couldn't go to sleep, and after I'd been in bed about an hour I got up and sat by the window. I was staring down into the garden, and all of a sudden I saw something white begin to move and creep about. I watched it a few moments and I got the idea it was a burglar or a sneak thief, it kept so close to the house. I came down to call Mr. Littell and bumped into you."
"Do you suppose it is Libbie?" chattered Esther. "Why would she go into the garden in the middle of the night?"
"Walking in her sleep," explained Bob. "I've heard it is dangerous to waken a sleep-walker suddenly. Perhaps you'd better call Mrs. Littell, Betty, and I'll sit here on the window seat and see that she doesn't walk out into the road."
The two girls hurried off and tapped lightly on Mrs. Littell's door. That lady hurriedly admitted them, her motherly mind instantly picturing something wrong.
"It's Libbie," said Betty softly. "Bob saw her from his window in the garden and he thinks she's walking in her sleep. We don't want to frighten her. What can we do?"
"I'll be right out," said Mrs. Littell reassuringly. "Libbie's mother used to walk in her sleep, too. I think I can get the child into bed without waking her at all."
