Her eyes strayed nervously to an alarm clock that ticked away on a shelf over the sink. She wished the girls would come with the doctor. If little Peter was as sick as his mother thought he was, every minute might be precious. And besides that, they must get back to school.

Then she heard the girls’ voices mingled with the gruff tones of a man—the doctor, of course—and her heart jumped with relief. The next moment the door was flung open and Laura and Vi came in, followed by an immense man who seemed to completely fill the narrow doorway. Then Polly Haddon appeared in the doorway between the two rooms, an empty cup in her hand. At sight of the doctor she set down the cup and motioned him eagerly into the other room.

The latter glanced curiously at Billie, flung his hat on the kitchen table in passing, and disappeared with Mrs. Haddon into the sick room.

“Just luck that we happened to catch the doctor on his way out,” panted Laura, for the big man had hustled the girls back to the cottage on a run. “Say, Billie,” she added, her eyes lighting on the opened hamper, “I see you did the trick. Any bones broken?”

“Tell us about it,” begged Vi.

“I’ll tell you on the way home,” said Billie, her eye once more on the clock. “Miss Walters told us not to stay long, you know. We were to come right back.”

“Gracious, look at the time!” cried Laura, in consternation, following Billie’s eyes to the clock. “Miss Walters will think we have eloped.”

“I wish we could wait and see what the doctor says,” protested Vi, hanging back, and just then Billie raised a warning finger.

“Listen,” she said.

The doctor had raised his voice for a moment and his words came clearly to the girls where they stood near the door.
