Hannah and William left about eight o’clock, locking the kitchen door behind them, and the girls stayed out on the front porch until ten, talking and singing to Jane’s ukulele. The threatening storm had not arrived when they finally went to bed.

It was so still, so hot outdoors that not even a branch moved in the darkness. The very silence was oppressive; Jane was sure that she wouldn’t be able to go to sleep when she got into Miss Mattie’s wooden bed with its ugly carving on the headboard. But, in spite of the heat, both girls dropped off in less than five minutes.

They were awakened sometime after two by a loud clap of thunder. Branches of the trees close to the house were lashing against the windows, and the rain was pouring in. Mary Louise jumped up to shut the window. As she crawled back into bed she heard footsteps in the hall. Light footsteps, scarcely perceptible above the rain. But someone—something—was stealthily approaching their door!

Her instinct was to reach for the electric-light button when she remembered that Miss Grant used only oil lamps. Trembling, she groped in the darkness for her flashlight, on the chair beside her. But before she found it the handle rattled on the door, and it opened—slowly and quietly.

There, dimly perceptible in the blackness of the hall, stood a figure—all in white!

CHAPTER XI
The Picnic

The figure in white remained motionless in the doorway of Miss Grant’s room. Mary Louise continued to sit rigid in the bed, while Jane, who was still lying down, clutched her chum’s arm with a grip that actually hurt.

For a full minute there was no sound in the room. Then a flash of lightning revealed the cause of the girls’ terror.

Mary Louise burst out laughing.

“Elsie!” she cried. “You certainly had us scared!”
