After that one shriek her throat contracted with fright, and she lay as if paralyzed.

That horrible thing was so near she could almost touch it. Was it man—or beast—some prehistoric animal? She had never—not even in her wildest imagination—seen anything like this hideous monster. It stood in an upright position like a man and had long scrawny arms and legs, and huge frightful claws which seemed to be reaching out to grab her. Its head was hunched between its shoulders, and over the whole thing was a long, scraggly, hairlike covering.

With eyes fastened on the creature Peggy waited breathlessly. If only the thing would move or do something! Anything would be better than this suspense. But still it stood—motionless. If only she could manage to slide or crawl out of the room! But that monster would be sure to follow stealthily. Yet she must do something. She must get out of this room.

Forcing her eyes for a second from the monster, she glanced toward the door. The next instant she shuddered in fresh terror. There beside the door, almost at her feet, loomed another monster, taller and more horrible than the first.

Almost simultaneously there came a soft thudding sound from the tunnel. What could that be? Some other menace? It was getting nearer—nearer.

Suddenly above the thudding sounded a high-pitched voice—Jo Ann’s voice! Jo and Florence were running to her rescue! They had heard her scream.

“You must get out of this room this instant and warn the girls of their danger,” she commanded herself sternly.

Carefully, slowly, almost without seeming to move, she backed feet first toward the door. To reach it she had to pass so close to this other taller and more horrible creature that she would almost touch it. She held her breath. Already she could feel the clutch of those clawlike hands.

Steeling herself, she inched her body a little nearer. Out of the corner of her eye she watched those threatening claws. Brown leathery claws they were—dried—wrinkled—ghastly.

All at once the reason for their ghastly appearance darted into her mind—the hideous creatures were dead!
