“Nobody home, I guess,” he announced.

From her seat in the car Mary Louise stared at the house, peering into the strip of glass above the boards on the windows. She thought she saw a flicker of light, as if a candle were burning. Yes, she was sure of it—and—a face appeared at the window! Two frightened eyes looked right into hers. A second later another face appeared, more plainly than the first, for this person evidently had hold of the candle. The first face had vanished, and Mary Louise saw only that of an exceedingly ugly woman—someone who looked somehow familiar.

That very instant the tiny light went out, and at the same moment Mary Louise sank unconscious in her seat. A stone, hurled from the tree above her, had hit her right on the head!

CHAPTER VIII
Knocked Out

Max, who was standing on the ground near by, heard the heavy thud of the stone as it hit the floor of the car. Turning about sharply, he saw Mary Louise slumped in her seat, unconscious from the blow. He flung open the door and jumped in beside her.

[“Mary Lou! Mary Lou! Are you alive?” he cried desperately.]

The girl did not answer.

“Help! Help!” he shrieked, at the top of his lungs.

A mocking laugh sounded from the tree above. Max looked up, but in the darkness he could see no one. How he wished he had his flashlight! But it was behind in the rumble seat, and he daren’t waste a minute; he must get Mary Lou to a doctor with all possible speed.

Starting his engine immediately—for there was no reply to his call for help—he circled around the tree and crept cautiously down the slippery hill, praying as he had never prayed before. Oh, suppose Mary Louise were dead!
