Young Joe's nerves snapped. He leaped up with a shriek, and, springing across the room, fell beside Shand and clung to him.

"Did you hear it?" he cried. "It's out there! It's been following me! It's not human! Don't let it in!"

They were too much shaken themselves to laugh at his panic terror. Both men by the fire jumped up and turned around. Husky knocked over his box, and the cards scattered broadcast. He sidled towards the others, keeping his eyes on the door.

"Stop your yelling!" Shand hoarsely commanded.

"Did you hear it? Did you hear it?" Joe continued to cry.

"Yes, I heard it," growled Shand.

"Me, too," added the others.

Joe's rigid figure relaxed. "Thank God!" he moaned. "I thought it was inside my head."

"Listen!" commanded Jack.

They stood close together, all their late animosities forgotten in a common fear. There was nothing to be heard but the wind in the tree-tops.
